Tribal Gaming's Four-Track Response to Prediction Markets, Analyzed

Tribal gaming's response to prediction markets has moved beyond a single lawsuit. Over the past year, tribes and their trade organizations have built what amounts to a multi-front campaign: federal and state litigation, formal comments to regulators, resolutions calling on Congress to act, opposition to legislative text, and, this week, a main-stage industry panel at the Global Gaming Expo in Las Vegas. Understanding how these efforts fit together helps explain both the strengths of the tribal position and the obstacles it still faces in the fight over prediction markets and tribal gaming exclusivity.

The core grievance is easy to state. Tribes hold Class III gaming rights under the Indian Gaming Regulatory Act, exercised through compacts negotiated with states, and many of those compacts trade revenue-sharing payments for exclusivity. Prediction-market platforms that list contracts on sporting events, tribal leaders argue, offer what amounts to sports betting without a compact, a license, or a revenue share. Kalshi, the best-known platform, maintains that it operates a federally regulated financial exchange rather than a gambling operation. How that classification question is answered determines whether the tribal compact system is affected at all.

Track one: the courts

Litigation has been the most visible track. Three California tribes and four New Mexico tribes have each sued Kalshi separately over the past year, advancing theories rooted in IGRA and in the location of gaming activity. Their cases have reached federal appellate courts, and other courts have addressed related questions in disputes involving states. Our analysis of the Ninth Circuit proceedings involving Blue Lake Rancheria and our coverage of the New Mexico tribes' suit explain the theories in detail.

The courts track has strengths and limits. A favorable ruling can be precedent-setting, but results in different circuits may not align, and litigation is slow relative to the pace at which prediction-market products are expanding. Tribes are also not the only litigants: states, including Connecticut, have taken their own enforcement steps, as our report on Connecticut's cease-and-desist action against nine prediction markets describes.

Track two: agencies and resolutions

A second track runs through regulators and formal statements. In May, Oklahoma Attorney General Gentner Drummond submitted a comment to the Commodity Futures Trading Commission calling Kalshi unequivocally gambling. On July 17, the Inter-Tribal Council of the Five Civilized Tribes adopted a resolution asking Congress and federal regulators to require prediction-market platforms to comply with existing tribal, federal, and state gaming laws. Our report on the Oklahoma tribes' position on prediction markets covers those developments.

These statements do two things. They build an administrative record that can be cited in later proceedings, and they signal that tribal opposition spans regions and operators, not just the plaintiffs in active cases. The tradeoff is that comments and resolutions do not bind anyone. Their value depends on whether regulators and lawmakers take them into account.

Track three: Congress

The legislative track has become more urgent as crypto market-structure legislation moves through the Senate. The Indian Gaming Association maintained its opposition to the revised Clarity Act ahead of a Senate cloture vote scheduled for September 15. Tribal concern centers on whether federal financial-market legislation could be read to strengthen the position of prediction-market platforms against gaming law. We examined the bill's text and the tribal objections in our analysis of the revised Clarity Act.

Congress is the track with the highest potential impact and the least predictability. A statute could settle the classification question across the country, but the outcome would depend on how the bill's language treats event contracts, and tribes have limited control over that drafting.

Track four: the industry coalition

The newest track is public coalition-building. At G2E 2026, which runs September 28 through October 1 at the Venetian Expo, the opening-day main-stage panel is titled "The Power of Unity: Confronting the Prediction Markets Challenge." The session, scheduled for 4:00 p.m. on September 28, was billed as a discussion of how prediction markets bypass tribal frameworks to offer backdoor sports betting. The panel is moderated by Jason Giles, executive director of the Indian Gaming Association, and includes IGA Chairman David Bean, American Gaming Association President and CEO Bill Miller, tribal advocate and political strategist Holly Macarro, and California Nations Indian Gaming Association Chairman James Siva.

The panel pairs tribal organizations with the commercial industry's national trade group, a signal that opposition to prediction markets is not confined to Indian Country.

The presence of the American Gaming Association alongside tribal groups matters. Tribal and commercial operators often disagree on sports betting, online gaming, and land-use questions, so a shared stance on prediction markets is notable. The title's emphasis on unity also acknowledges a real problem: as our piece on fractures in tribal consensus documents, tribes have not all reached the same position on how to respond. Readers can preview the broader agenda in our G2E 2026 tribal gaming agenda preview.

What the campaign has to prove

Each track supports the others, but none has yet resolved the underlying question. Court rulings have not produced a uniform national answer, agency comments are not decisions, and legislation remains pending. The strength of the campaign lies in its breadth, since it does not depend on a single forum. Its weakness is the same breadth: coordinating positions across many tribes, with different compacts and business interests, is difficult.

The next several months will show which track carries the most weight. For the legal framework behind all four, the site's Legal Guide to IGRA and Class III gaming offers background, and the events calendar lists upcoming industry meetings where the issue is likely to surface.
