Seventh Circuit takes Kalshi tribal land case as IGRA conflict widens

The Ho-Chunk Nation did not file its lawsuit over a legal abstraction. It filed because Kalshi was offering sports-event contracts to users on tribal land without tribal gaming authorization, and two federal courts had already said that the Indian Gaming Regulatory Act applies to those contracts regardless of what the Commodity Exchange Act says about designated contract markets. The Seventh Circuit has now agreed to hear Kalshi's appeal of the Wisconsin federal court's denial of its motion to dismiss. That decision to grant the petition is where this story actually begins.

The UIGEA carveout is the mechanism Kalshi has been relying on. The Unlawful Internet Gambling Enforcement Act contains a specific exemption for CFTC-regulated designated contract markets, and Kalshi's argument is that this exemption insulates its contracts from state and tribal gambling law. Both the Ninth Circuit, in Blue Lake Rancheria versus Kalshi, and the Western District of Wisconsin have rejected that argument in the tribal context. They held that IGRA's tribal gaming authorization requirement survives the UIGEA carveout. The Seventh Circuit taking the case does not disturb those rulings. It means a third federal court is now examining the same question with the benefit of two prior answers it is not bound to follow.

I have spent enough time in proceedings where one circuit's read on a preemption carveout diverges from another's to know that the Seventh Circuit's interest here is not neutral. Courts grant petitions because they see something worth examining. The more instructive possibility is that the panel wants to test whether the Blue Lake and Wisconsin analyses hold when pushed harder on the UIGEA text. If the Seventh Circuit reads the carveout more broadly, you have a circuit split on tribal land applicability of IGRA to CFTC-regulated markets. A circuit split on a question this structural does not stay unresolved.

The consensus read on this litigation treats IGRA as a secondary front — smaller than the state preemption fights in Utah, Missouri, and Wisconsin, less commercially urgent than the criminal exposure Kalshi's founders face. I think that framing is wrong about the timeline, if not the stakes. The state preemption cases turn on whether the Commodity Exchange Act's exclusive jurisdiction language displaces state gambling regulation. That is a clean federal question that moves toward the Supreme Court on a track everyone can see. The tribal question is structurally different because IGRA is its own federal regime. Kalshi is not arguing that tribal gaming law is preempted by federal law. It is arguing that one federal statute's carveout reaches inside another federal statute's authorization framework. That argument has lost twice. The Seventh Circuit is now the third examination.

Gaming attorney Daniel Wallach noted publicly that the court's consideration of this issue could have significant implications for the intersection of federal prediction market regulation and tribal sovereignty. The legal standard the Seventh Circuit will apply is whether IGRA's requirement of tribal authorization for gaming on Indian lands survives the UIGEA's carveout for CFTC-regulated designated contract markets — and whether Congress, in drafting that carveout, intended it to reach gaming conducted on tribal land subject to a separate and comprehensive federal authorization scheme.
