Nevada regulators have taken the first formal step toward banning convicted California bookmaker Wayne Nix from every casino in the state, in a move that tightens the link between anti-money-laundering enforcement and individual suitability for access to the Strip.
At a meeting in Las Vegas on Wednesday, the Nevada Gaming Control Board (NGCB) voted to nominate Nix for placement on the state’s List of Excluded Persons – the so-called “Black Book”. The Nevada Gaming Commission will make the final decision later this month; if it agrees, Nix will join a small group of fewer than 40 people permanently barred from setting foot in any licensed casino.
The case is directly tied to earlier findings that MGM Grand and the Cosmopolitan accepted millions in cash and wagers from Nix while he was running an illegal bookmaking business in California.
From Strip high-roller to would-be casino outcast
Nix, a former minor-league baseball player, pleaded guilty in April 2022 in federal court to conspiracy to operate an illegal gambling business and to filing a false tax return. His sentencing, repeatedly delayed, is now set for 6 March.
According to evidence summarised by state lawyers, Nix took bets from clients in California and other states, then travelled to Las Vegas with the proceeds in duffel bags, paper sacks and designer purses. Once in Nevada, he used that cash to gamble, settle casino markers and cultivate relationships with marketing hosts, offering commissions in return for referrals to new players.
Investigators later concluded that the MGM Grand accepted around US$4m in cash from Nix, while the Cosmopolitan – now under MGM control but separately managed at the time – booked more than US$900,000 in wagers linked to him.
Those transactions became central to a wider anti-money-laundering (AML) probe that cost former MGM Grand president Scott Sibella his gaming licence. Sibella pleaded guilty in 2023 to failing to file required reports on Nix’s activity; in April 2025, MGM Resorts agreed to pay a US$8.5m penalty over AML failures involving Nix and another bookmaker.
Board: Nix “has no place” in Nevada casinos
Presenting the exclusion case, Deputy Attorney General Mike Somps argued that Nix met multiple statutory grounds for being blacklisted: he is a convicted felon, has breached California gaming laws, and has what the complaint described as an “unsavoury reputation” that could undermine public confidence in regulated gambling.
Board member George Assad said the bookmaker’s conduct went far beyond ordinary high-stakes play. In his words, Nix “wasn’t in Nevada just to gamble, but was laundering money”, and regulators needed to send a clear signal that casinos cannot serve as a conduit for illegal bookmaking proceeds.
“We’re not going to tolerate it here in Nevada,” Assad added, arguing that formal exclusion is one way to “change the culture up and down the Strip” by drawing a bright line between regulated operators and off-the-books betting rings.
NGCB chair Mike Dreitzer underlined that Nix was widely recognised on the Strip as a bookmaker, not a typical tourist. In the board’s view, he “has no place being in a casino at any time in Nevada” and his presence poses “a threat to the interests of the state and licensed gaming generally”.
Nix did not appear at the hearing and has not commented publicly on the proceedings.
Part of a wider AML crackdown
The Nix case is one of several recent enforcement actions in Nevada where illegal bookmakers and casino AML controls have collided.
In the past year, regulators have also sanctioned Resorts World Las Vegas and Caesars Entertainment over their dealings with another California bookie, Matthew Bowyer, whose network was linked to former Los Angeles Dodgers star Shohei Ohtani’s ex-interpreter. Resorts World agreed to a US$10.5m settlement earlier in 2025, while Caesars Palace last month accepted a US$7.8m fine and pledged to overhaul its AML programme.
In that Caesars case, chief executive Tom Reeg told commissioners “there is no customer that’s worth illegitimate profits” and acknowledged that the company “didn’t catch Bowyer and we should have”.
Assad told Wednesday’s meeting that both Nix and Bowyer have “brought so much negative publicity to the state” that they now “certainly qualify for the list of excluded persons”. The Board will hear Bowyer’s own Black Book case in January.
Implications for operators: suitability in the spotlight
For Nevada licensees, the Nix nomination underscores how aggressively regulators now link individual patron behaviour, AML controls, and corporate suitability.
In the MGM matter, investigators found that casino executives and hosts had ample warning signs about Nix’s background, yet continued to extend him credit and accept large cash buy-ins. That pattern fed directly into the US$8.5m settlement and the revocation of Sibella’s licence.
The Black Book case now adds a second layer of consequence. If the Commission approves the exclusion, MGM and every other Nevada operator will have a clear obligation to permanently bar Nix from their properties, with the risk of further disciplinary action if he is allowed to play.
Deputy AG Somps told the Board that Nix’s use of casinos as a hub for his betting business – meeting clients, paying debts, and recruiting new customers – blurred the line between regulated and unregulated markets in a way that regulators cannot ignore.
Nix ruling to signal how far Nevada will go on AML enforcement
The Nevada Gaming Commission is expected to consider Nix’s Black Book nomination at its meeting later this month. Approval would make him one of a small number of individuals formally “persona non grata” in the state’s casinos, a designation that regulators say is reserved for cases where criminal conduct and reputational harm intersect.
Whatever the outcome, the proceedings mark another escalation in Nevada’s effort to show that high-end patrons and long-standing relationships are no defence when casinos become entangled with unlicensed bookmaking and weak AML controls.
