California tribe sues Kalshi over alleged breach of gaming compacts

California tribe files suit claiming Kalshi bypasses tribal gaming compacts

A California tribe has gone to federal court arguing that Kalshi's sports event contracts violate tribal gaming compacts that give Native nations exclusive authority over sports betting within state boundaries. The suit adds a fifth legal front to a jurisdictional fight that the CFTC's own general counsel has already described, in public testimony, as voluminous.

The tribal claim is structurally different from what Ohio, Illinois, and Arizona have brought. State enforcement actions rest on gambling statutes — the argument being that a sports event contract is a wager dressed in derivatives language. The tribal complaint rests on compact authority, a distinct legal instrument negotiated between sovereign nations and state governments, ratified under the Indian Gaming Regulatory Act. IGRA creates a federal framework that sits alongside, not beneath, the Commodity Exchange Act. The preemption question that has carried Kalshi through Illinois and carried Kalshi through Ohio does not automatically answer the compact question. These are different sources of law, and the Supremacy Clause analysis that displaces a state gambling statute does not reach into a federal compact the same way.

Rob Schwartz, a former CFTC general counsel who moderated the Predict 2026 discussion in New York this week, called the broader jurisdictional picture a litigation mess, and that framing predates this filing. Tyler Badgley, the CFTC's current general counsel, organized the litigation into four categories: DCMs suing states, states pursuing criminal enforcement, the CFTC seeking injunctions, and everything else. The tribal suit is everything else. Badgley used that phrase with some precision — class actions, IGRA claims, collateral enforcement. That bucket is the one without a clear procedural track, and it is filling up.

What the compact theory does is route around the swap-versus-gambling binary that has defined the litigation to date. Federal courts have been asked, repeatedly, to decide whether a sports event contract is a CFTC-regulated derivative or state-regulated gambling. That is a binary that the IGRA framework does not need to resolve. A tribe can argue that regardless of how the contract is classified, the compact grants exclusivity, and that exclusivity is a federal right. The CFTC's designation of Kalshi as a DCM does not, on its face, abrogate a compact. Whether it implicitly does so is a question that has not been litigated in this context.

I have not seen a prediction market contract on this specific tribal claim. The markets tracking Kalshi's Supreme Court petition are pricing federal preemption as the dominant theory. I think that is mispriced in one direction: the preemption wins, if they come, resolve the state statute claims. They do not resolve the compact claims. Those require either Congressional action or a separate body of litigation that runs on a longer clock than anything the Supreme Court term will settle.

The legal standard that applies here is whether the Indian Gaming Regulatory Act's compact framework is preempted by the Commodity Exchange Act, and whether CFTC designation of a contract market constitutes federal authorization sufficient to override tribal exclusivity rights negotiated under a separate federal statute.
