During the recent 2026 Indian Gaming Tradeshow and Convention held in San Diego, prediction markets emerged as a central topic of discussion. In states like California and Florida, these markets have seen notable growth recently, raising alarms among Indian gaming officials who view them as a potential threat to tribal sovereignty. The market valuations of operators such as Kalshi and Polymarket have dramatically increased in 2026, leading to heightened concerns among tribal leaders regarding the competitive landscape of these trading platforms. At the conference, IGA Chairman David Bean warned that upcoming legal rulings will ultimately hold greater weight than public sentiment on this contentious issue.
After the conference concluded, a decision by the US 3rd Circuit Court of Appeals posed a setback for tribal gaming interests. In a close 2-1 ruling, the court determined that New Jersey could not temporarily prohibit Kalshi from providing sports event contracts within the state. Meanwhile, Jason Giles, executive director of the IGA, signaled that this case is among many that the organization is keeping an eye on.
In a significant ruling last November, the California District Court in the case Blue Lake Rancheria vs Kalshi dismissed claims that the Indian Gaming Regulatory Act took precedence over the Unlawful Internet Gaming Enforcement Act, a pivotal internet gaming regulation from 2006. Although this outcome was disappointing, Giles expressed satisfaction with the early rulings against prediction market operators in various states as they continue to unfold.
Giles remains focused on the ongoing efforts by states to engage in a drawn-out battle against prediction markets. Currently, more than a dozen states are pursuing lawsuits against these operators. "Anywhere they’re operating, they’re going to be sued," he stated, noting that states are becoming increasingly aware of the challenges posed by these market players.
The issue of anti-money laundering, or AML, also resurfaced at IGA, following last year's extensive money laundering controversies along the Las Vegas Strip. Weak AML practices at numerous Strip casinos facilitated illegal bookmakers in laundering their profits through these establishments. In response, Nevada regulators issued significant fines, amounting to millions of dollars, against at least four companies – Resorts World Las Vegas, Wynn Resorts, Caesars Entertainment, and MGM Resorts. Two of these entities also entered into non-prosecution agreements with the Justice Department, leading to major upgrades in AML and Know-Your-Customer protocols across Strip casinos.
In previous IGA discussions, the balancing act between compliance and cost efficiency was a hot topic. Last year, illegal bookmaker Matt Bowyer was awaiting sentencing on multiple charges, including transactional money laundering. Following his sentencing to five months in federal prison, Bowyer was included on Nevada's exclusion list, preventing him from entering licensed casinos. He garnered significant attention when he was transferred to a California halfway home after serving part of his sentence. Bowyer was noted for taking in $325 million in sports wagers from Ippei Mizuhara, the former interpreter for baseball star Shohei Ohtani.
Bowyer's situation drew attention again last month, as discussions about his past activities continued, notably his involvement with Pechanga Resort Casino in California, where Mizuhara reportedly repaid debts to Bowyer's associate linked to marker accounts. To date, Pechanga has not faced any charges in connection with Bowyer.
The IGA also featured a panel on compliance and data protection, where Melissa Aarskaug from Druvstar highlighted significant blind spots that may hinder compliance efforts in the casino industry. Aarskaug drew comparisons to challenges faced by Stryker Corporation, which reported a severe cyberattack in March that compromised sensitive employee data.
Amid advancements in AI, a panel emphasized the importance of human interaction in compliance efforts. Experts discussed the effectiveness of contemporary surveillance technologies like facial and voice recognition, but cautioned that these systems can fail if different departments within a casino do not share crucial information. Andrew Cardno, chief technology officer at Quick Custom Intelligence, explained the complexity of integrating numerous monitoring systems, noting the daunting challenge of achieving real-time integration when multiple systems are in place.
In the early stages of the IGA, Arizona Attorney General Kris Mayes’ lawsuit against Kalshi generated significant dialogue. Filed last month, Mayes accused Kalshi of running an unlicensed gambling operation, marking the first instance of criminal charges against the company in the US. Martin Harver, president of the Salt River Pima Maricopa Indian Community, expressed concerns over potential tax revenue losses and the lack of age verification systems that allow underage individuals to trade in sports contracts.
In response to the rise of prediction markets, IGA leaders announced the establishment of a litigation fund aimed at defending tribal sovereignty. Although details regarding funding targets and specific case allocations remain forthcoming, Giles underscored the necessity for such a fund when facing major entities.
Additionally, California implemented new regulations banning traditional blackjack games at card rooms, benefiting tribal interests that have long advocated for these restrictions. James Siva, chairman of the California Nations Indian Gaming Association, emphasized the legal grounds for challenging the games that were previously being offered.
