2025 was a tumultuous autumn for the American sports betting industry, with a series of scandals involving athletes, bookmakers, and casinos from the beginning to the end of the year, pushing old issues such as sports integrity and regulatory effectiveness back into the spotlight. From the massive theft case involving Shohei Ohtani's translator to NBA and MLB players suspected of manipulating games, to top Las Vegas casinos receiving hefty fines for inadequate anti-money laundering efforts, these events force us to question: Has the legalization of sports betting truly made the games safer?
Major cases burst in succession, from translation theft to league scandals
In January this year, federal law enforcement arrested Shane Hennan at Las Vegas airport as he attempted to flee to Colombia, kicking off the year's scandals. By October, nearly thirty defendants including Hennan and Miami Heat guard Terry Rozier were widely indicted, with prosecutors calling it the "largest scale gambling enterprise dismantling operation" since the repeal of the PASPA Act in 2018. Among these, the most notable was the case of Shohei Ohtani's former translator Kazuhiro Mizuura. He was sentenced to 57 months in prison before the Super Bowl, for stealing nearly 17 million dollars from the MLB superstar to pay off gambling debts to illegal bookmaker Matt Bower. Mizuura had bet a total of 325 million dollars with Bower, and was still owing 24 million dollars when arrested, a sum likely never to be recovered. This stirred up a hornet's nest, leading to the uncovering of even larger issues.
Casino regulation red flags, Las Vegas giants receive hefty fines
The Mizuura case not only exposed individual crimes but also tore open huge gaps in anti-money laundering (AML) compliance in Las Vegas casinos. Investigations found that illegal bookmakers like Bower were laundering money by gambling heavily in casinos. "Casino A," matching the characteristics of "Resorts World Las Vegas" (RWLV), became a disaster area, with Bower and another bookmaker each losing 10 million dollars there. Despite lacking proof of legal funding sources, Bower was able to bet millions each time at RWLV, even with executives altering his profession in internal meetings to cover up his bookmaker identity.
As a result? This spring, the Nevada Gaming Commission issued a series of record-breaking fines: RWLV was fined 10.5 million dollars (the second highest in state history), MGM Resorts settled for 8.5 million dollars, and Wynn Las Vegas was fined 5.5 million dollars. In October, Caesars Entertainment also settled for 7.8 million dollars due to related issues. Former Deputy Governor Brian Krolicki called these scandals a "wake-up call" that all of Las Vegas Boulevard must adhere to regulations. These are not small numbers.
League integrity eroded, regulatory model debate heats up
The sports leagues themselves are also mired in controversy. Apart from NBA's Rozier, prosecutors also accused Portland Trail Blazers coach Chauncey Billups of participating in gang-manipulated poker games and leaking team information. Two pitchers from the Cleveland Guardians were accused of deliberately pitching poorly to manipulate "micro-betting" outcomes, directly prompting MLB to reach an agreement with major betting companies to limit micro-betting to 200 dollars.
This series of events sparked a fierce debate: Has the legalization of sports betting made the games more transparent, or has it made them more susceptible to corruption? New York State Representative Paul Tonko believes that the current state-by-state regulatory model has "fundamental flaws," and relying solely on leagues and state regulatory agencies' "voluntary self-regulation" is ineffective. Former New Jersey Governor Chris Christie argued that the regulated market is still functioning. This debate concerning the soul of sports and the future of the betting industry will continue into 2026 and beyond.
