The Macau underground may face impact from new China corruption law

Macau, China, USA. 2 September 2026. Shaw, N. Source: MACAU DAILY TIMES 澳門每日時報

A draft of a Macau anti–corruption law and jurisdiction framework is an attempt to combat underground gambling and transnational crime networks.

The draft also contains a sovereignty clause, stating China may take countermeasures or blocking measures if another country improperly applies its anti-corruption laws extraterritorially against Chinese citizens, companies or organizations in ways that harm China’s sovereignty, security or development interests.

New enforcement framework

The draft would establish a national cross-border anti-corruption mechanism, led by the National Commission of Supervision. Departments responsible for foreign affairs, public security, justice, finance, commerce, anti-money laundering, auditing, state assets, financial regulation, securities regulation and cyberspace administration would participate, according to their responsibilities.

The framework would manage interdepartmental investigations, prosecutions and international cooperation. It would also require authorities to monitor cross-border corruption risks in sectors considered vulnerable to bribery and related financial misconduct.

The draft allows Chinese authorities to seek assistance from overseas institutions in locating suspects, investigating financial accounts, obtaining testimony and documents, freezing assets, confiscating illegal proceeds and returning recovered property. It also provides for cooperation involving extradition, the transfer of sentenced persons, repatriation and overseas prosecution.

Cross-Border Corruption Law Poses New Challenges in Macau’s Fight Against Underground Gambling

Macau’s battle against underground gambling is increasingly becoming a battle over borders.

Illegal money changing, underground banking, proxy betting, unlawful lending and the laundering of criminal proceeds through casino chips can involve transactions spanning Macau, mainland China, Hong Kong and overseas financial networks. The problem for investigators is straightforward but formidable: a gambling transaction may occur in Macau while the money, suspects, evidence and alleged corruption supporting it are scattered among several jurisdictions.

China is now developing another potentially powerful weapon against that problem.

In August 2026, Chinese lawmakers began reviewing a draft law specifically targeting transnational corruption. The proposed legislation is intended to close gaps in China's ability to investigate cross-border corruption, recover illicit assets, pursue suspects abroad and cooperate with foreign jurisdictions. The first draft contains six chapters and 47 articles.

For Macau, whose enormous gaming industry operates alongside one of the world's most closely controlled borders for capital movement, the implications could be significant.

A Casino Industry Built Around a Border

Macau occupies a unique position in Chinese law.

It is part of China, but maintains its own legal system under the "One Country, Two Systems" framework. While gambling permitted in Macau resorts, it remains generally prohibited in mainland China. Likewise, money that can legally be wagered on a Macau casino floor may have crossed the border through transactions that violate mainland financial, gambling or corruption laws.

That distinction has helped create an underground financial industry around Macau gaming.

For decades, VIP junkets provided credit and financial services to wealthy mainland gamblers. As authorities dismantled much of the traditional junket system, some of the demand shifted toward smaller and more decentralized networks: illegal money changers, underground banks, informal lenders and electronic-payment intermediaries.

The physical bet may therefore be the least complicated part of the transaction.

A gambler might transfer renminbi to a mainland account controlled by an underground banking network, and receive Hong Kong dollars or casino chips in Macau. The money could subsequently pass through other gamblers, intermediaries or businesses before returning to the mainland or moving overseas.

When corruption facilitates any part of that chain, investigators encounter an immediate jurisdictional problem.

Beijing's New Cross-Border Weapon

China's proposed transnational corruption law represents an effort to address precisely this type of difficulty, on a broader scale.

The draft legislation received its first review by the Standing Committee of the National People's Congress on August 25, 2026. According to official reporting, it is intended to improve mechanisms for case handling and international cooperation while addressing persistent difficulties in detecting corruption, gathering evidence, recovering illicit assets and securing convictions.

The proposal follows years of increasingly aggressive Chinese efforts to pursue corruption beyond mainland borders.

Under China's Operation Sky Net, launched in 2015, authorities have pursued fugitives and illicit assets overseas. Reuters reported in August 2026, that more than 3,000 fugitives had been returned from roughly 120 countries and approximately US$10 billion in assets recovered since the operation began.

China had already expanded the reach of other economic laws. Its revised Anti-Unfair Competition Law, effective October 15, 2025, strengthened provisions against commercial bribery and established jurisdiction over certain unfair competitive conduct occurring outside mainland China when that conduct harms China's domestic market or Chinese business operators.

The new transnational corruption proposal goes further by constructing a dedicated framework for corruption extending across national or jurisdictional boundaries.

For Macau's gaming industry, that raises an important question:

Where does Macau's jurisdiction end, and mainland China's anti-corruption jurisdiction begin when the same criminal enterprise operates in both?

The Underground Gambling Problem

This is not an abstract legal issue.

Underground gambling networks rarely organize themselves according to jurisdictional boundaries.

Consider a hypothetical operation in which a mainland official or businessman wants to gamble HK$5 million in Macau without moving an equivalent amount legally through China's financial system.

An underground banker could accept RMB in Guangdong. An associate in Macau supplies casino chips. Another intermediary settles accounts in Hong Kong. Cryptocurrency could eventually be used to balance the books among participants.

If corrupt payments are involved, the same operation potentially touches gambling law, banking regulation, money laundering, commercial bribery and public corruption.

• The casino transaction occurs in Macau.
• The RMB transfer occurs in mainland China.
• The settlement could occur in Hong Kong.
• The cryptocurrency might move through wallets controlled somewhere else entirely.

That fragmentation is one of the fundamental weaknesses criminals can exploit.

Macau Has Its Own Anti-Corruption System

Macau is not dependent upon mainland law to prosecute corruption.

Its anti-corruption framework includes the Macau Penal Code, Law No. 19/2009 on the Prevention and Suppression of Bribery in the Private Sector, and Law No. 10/2014 governing corruption in foreign trade.

The Commission Against Corruption of Macao, or CCAC, investigates corruption involving both public and private sectors.

But Macau itself acknowledges difficulties with its existing legislation.

The CCAC's 2026 policy program says Macau's private-sector anti-corruption law has been in force for 16 years and now contains significant differences compared with laws in neighboring jurisdictions and international conventions applicable to Macau. The commission says those differences create "difficulties and challenges" in applying the law and plans to study substantial revisions.

That matters enormously to gaming.

Integrated resorts are enormous private-sector businesses involving casinos, hotels, retail operations, contractors, financial relationships and thousands of employees. The CCAC specifically identified management of integrated resort enterprises among areas appearing in its private-sector corruption caseload.

The regulatory challenge is therefore not limited to corrupt government officials.

It can include private commercial corruption as well.

The Evidence May Be Somewhere Else

Cross-border corruption investigations have another fundamental problem: the investigator and the evidence may be in different jurisdictions.

Macau investigators can obtain casino surveillance footage, gaming records and evidence located within Macau. But an investigation into an underground gambling network might also require mainland bank records, Hong Kong corporate documents, telecommunications records, cryptocurrency exchange information or testimony from suspects outside Macau.

Macau's existing foreign-trade corruption legislation does not itself solve all those problems. A 2026 legal review of Macau's anti-corruption framework notes that the legislation addresses cross-border bribery but does not establish a comprehensive mechanism for harmonizing cooperation and forensic difficulties between overseas authorities.

Differences between legal systems compound the problem.

Conduct treated as one offense in Macau might fall under another statute in mainland China. Rules governing searches, electronic evidence, financial records, corporate liability and admissibility can differ.

That means investigators cannot simply collect evidence in one jurisdiction and assume it can automatically be used in another.

Macau, Hong Kong and Mainland China Must Cooperate

In practice, authorities are already moving toward deeper regional cooperation.

During the first nine months of 2025, Macau's CCAC handled 57 cross-border mutual-assistance cases. Of the 48 requests received from outside Macau, 36 came from mainland Chinese agencies and 12 from Hong Kong's Independent Commission Against Corruption or other Hong Kong enforcement departments. Macau itself made another nine requests for assistance outside the territory.

Those figures illustrate how routine cross-border corruption investigations are becoming.

The CCAC says Macau, mainland and Hong Kong authorities are developing regular exchanges to examine investigative strategies and the legal compatibility of cross-border corruption cases, particularly within the Guangdong-Hong Kong-Macau Greater Bay Area.

For underground gambling investigations, such cooperation can be indispensable.

Catching an illegal money changer inside a Macau casino is relatively simple compared with dismantling the financial organization behind him.

The person carrying HK$500,000 may be only the visible end of a network containing dozens of mainland mule bank accounts, intermediaries, lenders and settlement agents.

Corruption and Underground Banking Converge

The most serious risk occurs when underground gambling infrastructure becomes useful for purposes beyond gambling.

An informal settlement network capable of transferring gambling money between Guangdong and Macau can potentially launder other money as well:

• Bribes.
• Fraud proceeds.
• Embezzled public money.
• Proceeds of organized crime.

Once different sources of money enter the same settlement network, distinguishing gambling capital from criminal proceeds becomes substantially harder.

Casino chips add another layer.

They are not conventional currency, but inside a casino ecosystem they can temporarily function as highly liquid stores of value. Money can enter as cash, become chips, circulate through gaming activity and eventually emerge again through redemption.

This does not mean ordinary chip transactions constitute money laundering. It means investigators examining a criminal network must reconstruct the economic purpose behind apparently legitimate casino transactions.

Cryptocurrency Complicates the Border Further

Digital assets make the concept of a border even less useful.

An underground settlement system once required cash couriers, bank accounts and physical meetings. Stablecoins and other digital assets potentially allow portions of the settlement process to occur almost instantaneously.

A gambling-related debt created in Macau could theoretically be settled between cryptocurrency wallets without either party physically carrying money across the Gongbei border.

That changes the investigative problem from:

Who carried the money?

to:

Who controlled the wallet?

Authorities then have to reconstruct blockchain transactions with real individuals, bank accounts, mobile devices and casino activity.

Cross-border corruption legislation may provide authorities with additional mechanisms for pursuing the people and assets involved, but technology continues to make the underlying networks more geographically dispersed.

A Question of Jurisdiction

China's proposed legislation therefore creates an interesting challenge for Macau.

Stronger cross-border anti-corruption powers could make it considerably more difficult for corrupt officials, underground bankers and their intermediaries to exploit jurisdictional boundaries.

But enforcement must still coexist with Macau's separate legal system.

Macau has its own prosecutors, courts, criminal laws and anti-corruption agency. Mainland authorities have their own investigative and supervisory institutions.

The central issue will consequently be coordination rather than simply expanding enforcement.

Investigators must determine which jurisdiction has authority over particular defendants, where prosecution should occur, how evidence can legally be transferred, and how assets located in another jurisdiction can be restrained or confiscated.

These questions become particularly complicated when a single organization commits different offenses on opposite sides of the border.

The Casino Operator Is Caught in the Middle

Macau's casino concessionaires also face potentially greater compliance burdens.

A major integrated resort may simultaneously have obligations arising from Macau gaming regulation, anti-money-laundering rules, private-sector corruption law and increasingly assertive mainland Chinese anti-corruption enforcement.

The revised Chinese Anti-Unfair Competition Law already increases exposure surrounding commercial bribery. The new transnational corruption legislation could further raise expectations surrounding companies and individuals whose business activities intersect with mainland China.

The draft law reportedly includes obligations concerning corporate integrity and compliance as well as legal liabilities for violations.

For Macau casino operators, that makes knowing the customer only part of the problem.

They increasingly need to understand the network surrounding the customer:

• Who supplied the chips?
• Who extended the credit?
• Where did the funds originate?
• Was an intermediary involved?
• Does the transaction have connections to an underground bank?
• Could an employee or outside agent be receiving an improper benefit?

Those questions push casino compliance far beyond conventional surveillance of gaming tables.

From Casino Policing to Network Policing

Macau's underground gambling problem has consequently evolved.

Twenty years ago, authorities could concentrate heavily on illegal bookmakers, loan sharks and recognizable junket organizations.

The modern underground gambling economy is more decentralized.

Its infrastructure may include casino floors in Cotai, smartphones in Zhuhai, mule bank accounts elsewhere in mainland China, companies in Hong Kong and digital wallets accessible almost anywhere.

China's emerging cross-border anti-corruption framework potentially gives authorities stronger tools to attack those networks.

Yet legislation alone cannot eliminate the jurisdictional problem.

Successful enforcement will depend upon intelligence sharing, compatible evidence standards, financial tracing and sustained cooperation among Macau, mainland China, Hong Kong and—in cases where money travels farther—foreign jurisdictions.

That is ultimately the paradox facing Macau.

The casinos remain firmly inside Macau.

The underground financial networks serving them increasingly do not.

As China expands the international reach of its anti-corruption regime, Macau may become one of the most important testing grounds for whether cross-border law can successfully confront a gambling economy whose money, intermediaries and evidence can move far more easily than the investigators pursuing them.

Eswatini gambling probe expands as police investigate organized crime

Eswatini • 28 August 2026 • Source: iGB

Eswatini’s Royal Eswatini Police Service (REPS) has reported to the High Court that the country’s illegal online gambling investigation has expanded into an international fraud and organized crime probe.

Detective Constable Ntokozo Dlamini of the Organised Crime Unit filed the affidavit. According to the document, Telegram and WhatsApp material recovered from seized devices pointed to alleged links between the criminal enterprise and senior politicians, police officials, and immigration officials, to investigate whether politicians were unwittingly renting accommodation to foreign nationals involved in illegal online gambling.

“I also want to request the PM as well, he must investigate for us and ascertain if these criminals who have been involved in online gambling are not in the homes of some of us,” — Mdluli said in the Senate.

Mdluli also flagged that penalties remain low enough for offenders to pay a fine and continue business. In June, 84 of the arrested foreign nationals were convicted of immigration offences, not gambling offences. Principal Magistrate Fikile Nhlabatsi handed down six-month sentences with the option of paying a fine of E500 (USD$30).

Investigation puts regulatory framework under scrutiny

Eswatini’s Gaming Control Act of 2022 is in force, but its implementing regulations are still being developed. MPs called for new gambling licences to be halted until the regulations are finalized and submitted before parliament, first during a House of Assembly sitting on 18 December 2025.

The Ministry of Tourism and Environmental Affairs has since paused new applications and renewed only four existing licences under strict oversight. The Ministry of Finance has told the High Court that the unregulated environment risks landing Eswatini on international financial crime grey market lists.

The forensic examination of the seized devices continues. The police say they will produce a comprehensive report at a later stage.

The findings could add further pressure on Eswatini to strengthen its gambling regulatory and enforcement framework. Either way, what began in March 2026 as a raid on unlicensed operators in Mbabane and Ezulwini has become a broader case involving multiple victims in a wide-ranging and sophisticated criminal enterprise. In all likelihood, it will have a significant impact on how gambling is regulated going forward.

Illegal Gambling in Eswatini: Online Betting, Underground Operations and a Growing Enforcement Challenge

Eswatini has a legal, regulated gambling industry, but beneath that market is a more complicated landscape of unlicensed betting, underground gaming, and potentially illicit online operations. The distinction is important: gambling itself is not prohibited in the Kingdom of Eswatini, but conducting or participating in gambling outside the country's licensing framework can constitute an offence.

Recent investigations have also pushed illegal gambling beyond the traditional image of a back-room card game. In 2026, allegations involving online operators, offshore money flows, immigration violations, and possible organized crime have put gambling regulation under considerably greater scrutiny.

From Gambling Houses to Online Platforms

Eswatini has prohibited unauthorized gambling for well over a century. The country's Crimes Act contains provisions making it an offence to keep or visit an unlawful gambling house and separately restricts unauthorized betting houses. It also provides for the forfeiture of gambling equipment and funds in certain cases.

The legal market, however, permits gambling conducted under government authorization. Casinos have historically operated under the Casino Act, which establishes licensing and operating requirements and regulates who may participate in casino gambling.

Modern gambling has increasingly shifted toward smartphones, internet betting, and electronic payments. Eswatini's current regulatory framework includes the Gaming Control Act No. 7 of 2022, which has already been used in criminal prosecutions involving allegations of participation in gaming outside licensed operations.

That distinction creates two parallel markets: licensed gambling businesses subject to regulatory oversight, and operators or networks that attempt to take wagers without the necessary authorization.

The Underground Market Goes Digital

Illegal gambling no longer necessarily requires a physical gambling den. An operator can potentially reach customers through websites, messaging applications, and mobile payment systems while locating servers, payment processors, or corporate entities outside Eswatini.

This presents regulators with a substantially different enforcement problem. A physical gambling house can be raided and its tables and cash seized. An internet gambling operation can move its infrastructure, accounts, and communications across several jurisdictions.

Eswatini's anti-money-laundering legislation specifically recognizes this development. Gambling houses, casinos, and lotteries—including operators carrying on such operations through the internet—are included among the country's "accountable institutions."

That means regulated gambling is not simply a licensing issue. It also sits within the country's financial crime prevention system.

The 2026 Mbabane Gambling Case

The scale that an alleged illegal operation can reach was illustrated by a major case reported in 2026.

According to the Eswatini Observer, 85 defendants appeared in connection with a gambling investigation in Mbabane and collectively faced 168 charges. The allegations included violations of the Gaming Control Act as well as 165 immigration-related counts. Prosecutors alleged that during February and March 2026 the accused unlawfully engaged in gaming involving an event or contingency other than through an appropriately licensed operator.

The case demonstrates how contemporary illegal gambling investigations can overlap with other areas of criminal and administrative law rather than remaining isolated betting offences.

Allegations of a Larger Gambling and Money-Laundering Network

Other developments in 2026 have raised even more serious allegations.

In June, Swaziland News reported that National Commissioner of Police Vusi Manoma Masango had recommended temporarily halting the issuance of gambling licences while police investigated what the publication described as a multibillion-emalangeni illegal-gambling and extortion scandal.

According to the report, preliminary investigations were examining indicators of alleged fraudulent gambling operations, cyber-enabled scams, money laundering, immigration abuses, and possible human-trafficking elements. These remain allegations and should not be treated as established findings unless proven through the courts or confirmed by authorities.

A subsequent July report described a dispute in which a gambling-company director accused another operator of having run an illegal online casino since 2019. That report also referred to investigations concerning offshore transfers and alleged tax evasion. Again, those allegations should be distinguished from proven criminal liability.

Taken together, the reports show why Eswatini authorities increasingly have to view illegal gambling as a potential financial crime problem rather than simply an unauthorized entertainment business.

Gambling and Money Laundering

Gambling businesses can be attractive to money launderers because they involve large numbers of financial transactions and can create an apparent explanation for the movement of funds.

Eswatini's Money Laundering and Financing of Terrorism (Prevention) Act places gambling houses, casinos, lotteries, and internet gambling operations within the country's AML framework.

The OECD's 2025 review of Eswatini similarly noted that the country's AML/CFT framework treats gambling, casinos, and lotteries as accountable activities subject to obligations including customer due diligence and identification of beneficial owners.

Regulatory authorities also publish specific AML/CFT and Know Your Customer guidance for casinos and gaming houses.

These requirements matter because an operator that accepts substantial wagers without effective customer identification can provide opportunities for disguising the origin or ownership of funds.

Why Illegal Online Gambling Is Difficult to Control

Eswatini faces many of the same problems confronting gambling regulators elsewhere in Africa. Offshore websites can accept local customers without maintaining a substantial physical presence in the country. Social-media and messaging channels can serve as informal betting networks, while electronic payments make wagering possible without a traditional bookmaker's counter.

Cross-border financial flows make enforcement still harder. A customer may be physically located in Eswatini while the gambling platform, corporate owner, bank account, and technical infrastructure are located in several different countries.

That creates a regulatory contest between increasingly borderless gambling technology and laws that ultimately have to be enforced within national jurisdictions.

A Changing Illegal-Gambling Landscape

Eswatini's underground gambling market is therefore better understood as a spectrum.

At one end are traditional unauthorized gambling rooms and informal bookmakers. At the other are sophisticated digital operations capable of handling wagers electronically and moving funds internationally. Between them are informal betting agents, unlicensed websites, and other arrangements that can blur the boundary between legitimate and illegal gambling.

The events of 2026 suggest that authorities are paying increasing attention to that boundary. Criminal prosecutions, police investigations, and greater scrutiny of gambling licences indicate that the government is treating unauthorized gambling as potentially connected to wider questions of taxation, immigration, cybercrime, and financial integrity.

For Eswatini, the challenge will be keeping regulation relevant as gambling continues migrating from casino floors and betting shops onto phones and international digital networks. The underground gambling den has not disappeared—it may simply no longer need a retail entrance.

Behind the Back Room: Underground Gambling Dens in Tennessee

Columbia, Tennessee, USA. 27 August 2026. LeDisco, Jacques. Source: Gamblers Den. Tennessee is hardly the first place that comes to mind when American gamblers think of casinos. The state has no commercial casino resorts, and its legal gambling market is largely confined to the Tennessee Education Lottery, charitable gaming permitted by law, fantasy sports and regulated online sports wagering.

Yet underneath that highly restricted market is an underground gambling economy—one built around illegal slot-style machines, cash payouts and businesses that can function as small, improvised gambling rooms.

Recent law-enforcement actions suggest that these operations are not merely relics of the old-fashioned back-room poker game. In parts of Tennessee, illegal gambling has migrated into convenience stores, tobacco shops, bars and other otherwise ordinary businesses.

The Modern Tennessee Gambling Den

The stereotypical gambling den is a hidden room filled with poker players, bookmakers and stacks of cash. Tennessee has certainly seen operations resembling that model. A federal prosecution announced in 2013, for example, alleged that an illegal gambling organization operating around Jackson used five locations, including businesses containing hidden rooms where customers played electronic slot machines.

Today's version can be considerably less conspicuous.

Rather than an obvious casino, investigators have increasingly encountered electronic gambling machines installed inside ordinary retail businesses. Players put money into machines resembling slots or sweepstakes games and, investigators allege, receive cash payout winnings.

That distinction is critical. An amusement game sitting in the corner of a store is legal; a machine being used to accept wagers and generate cash winnings is considered an illegal gambling operation.

The scale became dramatically apparent in Columbia in August 2026.

The $1.3 Million Columbia Crackdown

On August 25, 2026, authorities executed 22 search warrants at 20 businesses and two residences following an undercover investigation into suspected illegal gambling in Columbia.

According to the Columbia Police Department, investigators recovered:

• $1,328,269 in cash
• 144 gambling machines
• more than 100 pounds of kratom and THCA narcotics
• and arrested 13 people.

The investigation reportedly began in July after complaints from residents and businesses. Undercover officers subsequently infiltrated 50 businesses and identified 20 locations where authorities alleged that illegal gambling was occurring and cash winnings were being paid from gambling machines.

Those figures illustrate why illegal machine gambling can become much more than a handful of devices generating pocket money. When numerous locations are networked to operators, distributors or centralized cash management, what appears to be a collection of neighborhood machines can potentially develop into a substantial underground economy.

The Columbia raids involved local police along with the Tennessee Bureau of Investigation, IRS, ICE, the 22nd Judicial District Attorney's Office and other agencies.

Memphis and Shelby County

West Tennessee has experienced similar enforcement activity.

In 2024, authorities seized illegal gambling machines from five Shelby County locations, along with approximately $15,000. Officials said some of the investigated locations could also be connected with illegal firearms and money laundering.

Russian Roulette

The controversy has also involved machines marketed as so-called "No Chance Games."

In July 2025, a three-judge Tennessee Chancery Court panel ruled in Torch Electronics v. Mulroy that the machines at issue constituted illegal gambling devices under Tennessee law, according to the Shelby County District Attorney's Office. The ruling strengthened prosecutors' ability to seize machines despite arguments that their particular game mechanics removed them from conventional gambling laws.

Shelby County District Attorney Steve Mulroy has argued that illegal gambling locations can become associated with additional criminal activity and that authorities have pursued both the machines and proceeds generated from them.

Enforcement continued into 2026. In June, authorities investigating two Memphis stores reportedly seized eight slot machines and thousands of dollars characterized by investigators as gambling or drug proceeds.

Nashville's Gambling-Machine Problem

Middle Tennessee has faced its own publicity.

In June 2026, Nashville's Beer Permits Office publicly encouraged residents to report suspected illegal gambling machines in local businesses after media coverage generated numerous complaints. The city warned that criminal activity occurring at establishments holding beer permits could also expose operators to regulatory action against those permits.

Illegal gambling can consequently threaten much more than the machines themselves. A business may face criminal investigation, seizure of money and equipment and potentially separate licensing or nuisance proceedings.

A South Nashville establishment provides an extreme example. In August 2025, authorities padlocked 404 Bar and Grill after it was declared a public nuisance. Metro Police said the establishment had generated more than 120 police calls during approximately five and a half years involving allegations ranging from gunfire and drug transactions to fighting and illegal gambling.

The case does not mean gambling machines inherently produce those other crimes. It demonstrates, however, why authorities sometimes treat gambling locations as part of a broader public-safety risk rather than simply confiscating a machine.

Convenience Stores as Mini-Casinos

The most striking characteristic of Tennessee's modern underground gambling market may be how mundane its locations can appear.

A player does not necessarily descend a staircase into a smoke-filled basement. The entrance might simply be the front door of a neighborhood convenience store.

In Gallatin, police announced in August 2026 that searches of three convenience stores resulted in the seizure of 10 alleged illegal gambling machines, a cash payout machine that financial crime investigators believed had been associated with the machines. Three store owners were charged with possession of a gambling device.

This retail model has obvious advantages for an illicit operator. Existing businesses already provide electricity, customers, cash registers and long operating hours. Gambling machines can occupy relatively little retail floor space while attracting repeat customers.

However, the same characteristics also make the activity highly visible to investigators. Cash payouts, surveillance cameras, undercover play and the physical machines themselves can potentially provide evidence once police begin investigating.

Why the Machines Are So Controversial

Electronic gambling devices occupy a recurring battleground between machine operators and prosecutors.

Manufacturers may describe particular products as amusement, skill or sweepstakes games rather than gambling machines. Prosecutors look beyond the label to questions such as whether customers risk something of value, whether chance determines the return and whether winnings have monetary value.

Tennessee's criminal code addresses gambling promotion, aggravated gambling promotion and possession of gambling devices. Under Tennessee law, knowingly investing in, financing, owning, controlling, supervising, managing or participating in a "gambling enterprise" can constitute aggravated gambling promotion, a Class E felony.

Tennessee lawmakers have also moved to strengthen the state's ability to prosecute illegal gambling devices and online gambling through consumer-protection enforcement. Legislation passed by the General Assembly in 2026 addressed operating or possessing gambling devices and permitting gambling devices on premises controlled by a person, while preserving gambling specifically authorized under state law.

From Back-Room Casino to Digital Underground

Tennessee's illegal gambling landscape is simultaneously moving in another direction: online.

The state permits regulated online sports wagering, but that does not mean any website willing to accept a Tennessee customer is legal.

Tennessee regulators have repeatedly pursued offshore sportsbooks. By December 2025, the Tennessee Sports Wagering Council said it had served cease-and-desist letters on 24 illegal entities and assessed a combined $800,000 in fines against illegal online sports-gaming operators.

The Tennessee Attorney General has also targeted sweepstakes casinos. In December 2025, the office announced that cease-and-desist letters had been sent to almost 40 online sweepstakes casinos and said the targeted platforms had either disabled the disputed operations or agreed to shut them down.

The result is an underground gambling market divided between two worlds.

One is intensely physical: machines inside convenience stores, cash behind counters and gambling rooms concealed within legitimate retail businesses.

The other exists on smartphones and offshore servers, where the casino has no physical Tennessee address at all.

An Underground Industry Hiding in Plain Sight

Tennessee's gambling dens therefore do not necessarily resemble the secret casinos in popular culture.

Some still involve hidden rooms and private gambling. But increasingly, authorities describe something much more decentralized: a machine in a tobacco shop, several terminals inside a convenience store, a cash payout from a register or numerous retail locations connected to a larger operation.

The August 2026 Columbia investigation is particularly revealing. Authorities say undercover officers found suspected illegal gambling at 20 of the 50 businesses they checked, culminating in the seizure of 144 machines and more than $1.3 million in cash.

That is a revolution from a friendly poker game in somebody's basement.

It represents a shadow casino economy capable of embedding itself inside legitimate-looking retail businesses—operating without the regulatory controls, licensing requirements and consumer protections imposed on Tennessee's legal wagering industry.

And as Tennessee authorities intensify enforcement against both physical gambling machines and unlicensed internet operators, the state's underground gambling business is increasingly becoming a contest between technology, cash, creative interpretations of gambling law and investigators trying to determine exactly what is happening behind the counter.

Mainland man arrested for robbing suspected prostitute of RMB90,000

Judiciary Police (PJ) have arrested a 37-year-old mainland fruit shop owner for allegedly robbing a suspected mainland prostitute of RMB90,000 (USD$13,392) at a Cotai hotel room.

The suspect and the victim met in the hotel lobby on Aug. 20. Following a sexual transaction the next evening, the suspect held the victim in a headlock, threatened her with a fruit knife, and bound her hands and feet with tape to force until she disclosed her mobile transfer password. The victim was compelled to exchange money through illicit money exchangers for HKD100,000 in gaming chips, which the suspect lost while gambling.

The victim later reported the incident with a friend’s assistance.

Police recovered a 9-centimeter fruit knife and tape from the room. Investigations revealed the suspect purchased the items hours prior, indicating premeditation. The suspect will be transferred to the Public Prosecutions Office on charges of armed robbery. PJ officers are also separately investigating the victim’s suspected involvement in prostitution.

Behind the Casino Lights: Sex Work, Prostitution Networks and Trafficking Risks in Macau

Mahjong Makeout

Macau’s casino industry is famous for enormous integrated resorts, VIP gaming rooms and a nightlife economy built around millions of visitors. Alongside the regulated gambling business, however, a less visible commercial-sex economy has long operated in and around casino hotels, entertainment districts, massage businesses and other venues.

The distinction between independent sex work, organized prostitution and human trafficking is particularly important in Macau. Selling sex between consenting adults is not itself treated in the same way as operating a prostitution business or coercing another person into prostitution. Organizing, procuring or profiting from another person's prostitution can bring criminal charges, while trafficking for sexual exploitation is a serious criminal offense.

Macau police operations also demonstrate that foreign visitors engaged in prostitution can face immigration consequences even where investigators find no additional criminal offense, because working in the sex trade can violate the conditions under which they were permitted to enter or remain in Macau.

Why Casinos Attract the Sex Trade

The connection between prostitution and casinos is largely economic rather than a formal part of casino operations.

Macau concentrates large numbers of relatively affluent visitors into a small geographic area. Casino resorts combine hotels, restaurants, bars, entertainment venues and gambling floors, creating a substantial nightlife customer base.

Historically, sex workers and intermediaries have therefore gravitated toward areas surrounding casinos and casino hotels. Macau Judiciary Police cases show that commercial-sex activity has occurred around properties in Cotai, ZAPE and other casino districts, as well as inside hotel rooms.

A 2015 Judiciary Police investigation, for example, uncovered a Chinese-South Korean prostitution organization that recruited women and arranged transportation to areas around hotel casinos in the Dynasty and Cotai districts. Syndicate members solicited customers and booked encounters between customers and sex workers.

The casino, in other words, can function as a customer marketplace without the gambling operation itself necessarily being involved in prostitution.

Independent Sex Workers and Organized Networks

Macau's commercial-sex market cannot accurately be described as a single underground organization. It ranges from individuals working independently to highly structured criminal enterprises.

Police cases illustrate the difference.

In February 2025, Judiciary Police encountered a mainland Chinese woman in a ZAPE hotel who admitted coming to Macau to engage in prostitution and charging MOP 300 (USD$37) per transaction. Investigators reported finding no evidence that she was involved in another criminal offense, but she was referred to immigration authorities because the activity was inconsistent with the purpose of her authorized stay.

Other investigations have uncovered something different: organizations recruiting workers, advertising services, arranging transportation, supplying rooms, collecting money and controlling the commercial operation.

In a major 2019 investigation coordinated between Macau and Guangdong authorities, police said a syndicate used illegal telecommunications equipment to distribute advertisements for sexual services around casinos and even on hotel-and-casino shuttle buses. Phones and messaging applications were then used to arrange prostitution involving people from mainland China and Russia. Macau police arrested 23 alleged syndicate members and intercepted 25 sex workers during the operation.

Technology has consequently changed the business. Solicitation no longer needs to occur primarily on a casino floor or street. Websites, messaging applications and mobile advertising allow an organization to connect a customer near a casino with a worker located elsewhere.

The Cotai Casino-Hotel Environment

Cotai presents particularly favorable conditions for this decentralized model.

Its integrated resorts contain thousands of hotel rooms and enormous entertainment complexes while attracting a constantly changing population of visitors. A sex worker or intermediary can theoretically locate customers around entertainment areas while conducting the actual transaction elsewhere in a hotel.

A January 2024 police operation illustrates the pattern. Acting on information concerning suspected prostitution at a Cotai hotel, Judiciary Police coordinated with hotel security and subsequently intercepted eight mainland Chinese women. Police reported that the women admitted engaging in prostitution and quoted prices of HKD 1,500 - HKD 2,500 (USD$192-320) per transaction. They were subsequently referred to immigration authorities.

That case also demonstrates the increasingly important role played by hotel security departments. Casinos and hotels have substantial surveillance infrastructures, meaning coordination between resort security and police can make traditional physical solicitation considerably more difficult.

Organized Prostitution Can Be Extremely Lucrative

The scale of the underground economy became particularly visible in June 2026.

Macau Judiciary Police announced that 26 people had been arrested following a long-running investigation into three organizations allegedly operating prostitution businesses under the cover of sauna establishments.

Police alleged that the organizations operated between 2016 and 2024 and generated approximately MOP 230 million to MOP 320 million (USD$29-40 million) in illicit proceeds. Authorities seized assets worth more than MOP 50 million during the operation.

The case was especially significant because investigators alleged that serving and retired law-enforcement personnel consulted the organizations on how to evade enforcement activity in exchange for substantial payments. Police said the suspects communicated information about patrols and investigations using secret communications and prearranged code words.

The investigation demonstrates how organized prostitution can become something much larger than individual transactions between workers and customers. At sufficient scale it can involve property, advertising, financial management, transportation, corruption and organized-crime structures.

The Critical Issue of Human Trafficking

Not every sex worker is a trafficking victim, and prostitution should not automatically be equated with trafficking.

The distinction is nevertheless crucial because Macau has documented vulnerabilities to sexual exploitation.

The U.S. State Department's 2025 Trafficking in Persons assessment placed Macau in Tier 3 and reported concerns about the identification and protection of trafficking victims. The report said foreign victims have historically been recruited from mainland China, Russia and Southeast Asia, sometimes through misleading advertisements for modeling, entertainment or casino-related employment.

Reported trafficking indicators have included restrictions on movement, threats, excessive working hours and confiscation of identity documents. The report also noted historical allegations that personnel associated with some casino or entertainment establishments cooperated with criminal networks facilitating illegal commercial sex.

Macau has encountered such cases directly.

In an earlier Cotai investigation, Judiciary Police uncovered an organization suspected of recruiting women in mainland China and bringing them to Macau for prostitution. Police said the organization controlled the proceeds and retained substantial portions of the money generated by the women. Suspects were referred for prosecution on allegations that included human trafficking and criminal association.

The difference between consensual sex work and trafficking therefore matters enormously. A migrant voluntarily selling sexual services presents a fundamentally different situation from someone recruited through deception, debt, threats or coercion.

Debt and Economic Coercion

Exploitation does not always resemble physical imprisonment.

A 2025 Judiciary Police investigation concerned an Indonesian woman recruited to work as a massage therapist in Macau. Police said the business owner subsequently demanded that she provide sexual services to customers. According to investigators, her need to earn money to repay agency fees and support her family contributed to her compliance.

Authorities alleged that she had provided such services to more than 100 customers before the investigation. Two local men were referred to prosecutors on pandering-related allegations.

Cases of this kind demonstrate why investigators must examine recruitment fees, employment promises, control over earnings and immigration status rather than assuming that every person encountered in commercial sex entered the business under identical circumstances.

Casinos, Hotels and Enforcement

Macau's casinos operate within one of the world's most heavily monitored gaming environments. Modern integrated resorts employ extensive camera networks, security personnel and access controls.

Consequently, organized prostitution increasingly exists in an uneasy relationship with the legitimate casino industry.

Casinos provide what underground operators want—international visitors, affluent gamblers, nightlife and hotel accommodation—but those same properties possess sophisticated surveillance and security systems capable of detecting suspicious activity.

Macau authorities regularly conduct operations in casino districts and cooperate with hotel security. The result is a continuing contest between enforcement and increasingly decentralized commercial-sex networks.

A Changing Underground Economy

Macau's commercial-sex economy has evolved alongside the casino industry itself.

The traditional image of workers openly circulating around casino hotels captures only part of the contemporary market. Police investigations show an ecosystem that has included independent workers, massage and sauna establishments, hotel-based prostitution, online advertising, messaging platforms, transportation networks and sophisticated criminal organizations.

Recent cases also demonstrate that the sums involved can be substantial. The alleged MOP 230–320 million generated by the three organizations investigated in the 2026 sauna case shows that organized prostitution can operate as a significant underground business rather than simply an informal sideline to Macau nightlife.

Yet the most important distinction remains between consensual adult sex work and exploitation.

For Macau authorities, the challenge is not merely removing open prostitution from casino districts. It is identifying the organizations that recruit and control workers, distinguishing immigration violations from trafficking, detecting coercion and debt exploitation, investigating corruption, and ensuring that potential trafficking victims are recognized rather than automatically treated as offenders.

Behind Macau's casino lights, commercial sex therefore represents a complicated intersection of tourism, migration, organized crime, policing and the enormous economy surrounding casino gambling. The casinos may provide the geography and clientele, but the underground networks surrounding them reveal a much broader story about the businesses that develop wherever large amounts of money, transient visitors and nightlife converge.
