CFTC preemption claim narrows after Ninth Circuit tribal ruling

A federal appellate panel has now said, twice, that the Indian Gaming Regulatory Act can reach a CFTC-registered exchange. The second time, it sent the case back down rather than dismissing it. That distinction is doing a great deal of work.

The mechanics of what happened in the Ninth Circuit matter more than the headline suggests. Kalshi entered this litigation holding a CFTC designation as a designated contract market and argued, in effect, that federal registration under the Commodity Exchange Act occupied the field. The Ninth Circuit's answer was not that the argument was wrong in principle — it was that IGRA is a specific federal statute protecting a specific federal interest, and specificity in statutory construction tends to defeat generality. When Congress wrote IGRA, it was writing a rule about who gets to offer gaming in particular jurisdictions. A DCM registration is not a response to that rule. It operates in a different register entirely.

This is where Kalshi's legal position has a structural problem that goes beyond any single case. Federal preemption under the Supremacy Clause is strongest when Congress has either explicitly displaced state law or when the regulatory scheme is so comprehensive that displacement is implied. The CFTC's framework for event contracts does neither with respect to tribal gaming. The Commission regulates derivatives markets; it has never purported to settle the question of whether a contract that looks like a wager on an athletic contest is subject to IGRA. The Ninth Circuit is reading that silence correctly. The Commission's silence is not authorization. Authorization requires a text.

What I think the current market pricing on Kalshi's federal preemption argument misses is that the tribal cases and the state attorney general actions are not the same problem dressed differently. The Missouri AG's cease-and-desist, Kalshi's suspension from Washington state, the Massachusetts injunction — those are Supremacy Clause disputes. The Ninth Circuit tribal litigation is an IGRA dispute. IGRA has its own standing, its own enforcement mechanism, and its own legislative history that has nothing to do with derivatives market architecture. Kalshi can win every state preemption argument and still lose on IGRA, because the statutes don't talk to each other and the courts are not required to reconcile them.

The practical consequence is that the DCM designation Kalshi has spent years building as a regulatory moat may not extend to the geographic and legal territory it needs most. A platform that can offer event contracts in forty states but faces a categorical IGRA barrier to the remaining jurisdictions where tribal gaming compacts are operative has a business problem, not just a litigation problem. Those compacts cover more territory than the map of current enforcement actions suggests.

The Commission could resolve this by issuing a formal interpretation of how CEA jurisdiction interacts with IGRA. It has not done so. Under the Chevron framework as modified by Loper Bright, a court facing this question now gives the agency's silence considerably less deference than it would have three years ago.

The standard a reviewing court will apply is straightforward: whether Congress, in enacting the Commodity Exchange Act and its Dodd-Frank amendments, spoke clearly enough to displace a prior, specific federal statutory scheme protecting tribal gaming rights. The answer to that question is in the legislative record, not in the CFTC's registration decision.
