Scott Sibella pleaded guilty in January to violating federal anti-money laundering rules that required the casino to file reports of suspicious transactions. His sentence was handed down in federal court by U.S. District Judge Dolly Gee, who also ordered Sibella to pay a fine of $9,500. Gee took into consideration that Sibella, 61, took responsibility for his actions, cooperated with investigators, and had no previous criminal history.

Sibella’s attorneys had asked the judge to consider probation. They submitted testimonial letters of support, including one from Clark County Sheriff Kevin McMahill, the elected head of the Las Vegas Metropolitan Police Department.

The MGM Grand and nearby Cosmopolitan of Las Vegas previously settled a related case stemming from a U.S. Justice Department money laundering probe. The resorts agreed to pay a combined $7.45 million, submit to an external review and step up their anti-money laundering compliance programs.

Separately, Nevada casino regulators are considering revoking or suspending Sibella’s state gambling license and fining him up to $750,000. A complaint filed April 30 by state Gaming Control Board investigators has not yet been considered by the Nevada Gaming Commission.

The bookmaker central to Sibella’s case, Wayne Nix, is a former minor league baseball player who lives in Newport Coast, California. He’s awaiting sentencing after pleading guilty in April 2022 to operating an illegal gambling business and filing a false tax return.

According to his plea agreement with the government, Sibella allowed Nix to gamble at MGM Grand and affiliated properties with illicit proceeds generated from the illegal gambling business without notifying the casinos’ compliance department.

Sibella told federal investigators in January 2022 “that he had ‘heard that Nix was in the booking business’ and he ‘couldn’t figure out how he had all the money he gambled with.’”

“I didn’t want to know because of my position,” Sibella told investigators. “I stay out of it. If we know, we can’t allow them to gamble. I didn’t ask, I didn’t want to know I guess because he wasn’t doing anything to cheat the casino.”

Sibella was president and chief operating officer of the MGM Grand for eight years and then president of Resorts World Las Vegas until 2023.

His sentencing comes as the Justice Department undertakes a wide-ranging investigation into illegal sports gambling operations in Southern California laundering money through Las Vegas casinos. The most notable case involves Ippei Mizuhara, Los Angeles Dodgers star Shohei Ohtani’s former interpreter. Federal prosecutors say Mizuhara transferred money he stole from the Japanese superstar in a scheme to pay off debts to illegal bookmakers.

Sibella held top executive positions at The Mirage and Treasure Island casinos on the Las Vegas Strip before becoming president of the more than 6,800-room MGM Grand in 2011. He left the company in February 2019 and joined Resorts World Las Vegas before Malaysia-based Genting Group opened the $4.3 billion, 66-floor resort in June 2021.

Sibella was dismissed by Resorts World in September 2023 after the company said he “violated company policies and the terms of his employment.”
