6th Circuit Oral Arguments: July 30, 2026
Combined hearing for Ohio and Tennessee appeals. The outcome will shape how federal commodities law interacts with tribal sovereignty claims in circuits nationwide.
Most coverage of the prediction markets legal fight frames it as CFTC versus the states: a federal agency asserting that its license overrides state gambling laws under the Supremacy Clause. That framing fits the Sixth and Fourth Circuit cases well — but it misses a structurally distinct challenge that tribal nations are mounting in parallel.
Tribal gaming interests are not arguing that state law wins. They are arguing that the Indian Gaming Regulatory Act (25 U.S.C. § 2701 et seq.), enacted in 1988, is itself a federal statute — and that when two federal laws conflict, the Supremacy Clause provides no resolution. A court cannot hold that the Commodity Exchange Act displaces IGRA by declaring federal law supreme, because both laws carry equal federal dignity. That structural argument has now reached two federal circuits simultaneously.
KalshiEx LLC v. Schuler
No. 26-3196 (Ohio)
KalshiEX LLC v. Orgel
No. 26-5235 (Tennessee)
Central question: Does CFTC jurisdiction preempt state gambling enforcement? 30 Indian tribes and 11 tribal associations filed amicus briefs warning that a broad preemption ruling would undermine IGRA.
Blue Lake Rancheria, et al. v. Kalshi, Inc., et al.
No. 25-7504 (9th Circuit)
Central question: Does IGRA bar CFTC-licensed platforms from offering sports-event contracts accessible from tribal land, even if CEA preempts state gaming laws? Judges pressed Kalshi on whether its contracts are materially different from sports wagers when placed from tribal territory.
The core tribal argument has three layers, each building on the last:
Sports-event contracts = Class III gaming on tribal land
IGRA defines Class III gaming broadly to include casino-style games and sports wagering. Tribal gaming interests argue that when a user on tribal land places a prediction market contract on a sporting event outcome, they are engaging in Class III gaming regardless of how the contract is classified by the CFTC. The location of the user — not the classification of the product — triggers IGRA's compact requirement.
IGRA is federal law — the Supremacy Clause does not resolve federal-vs-federal conflicts
The Supremacy Clause (U.S. Const. Art. VI, cl. 2) makes federal law supreme over conflicting state law. It does not rank competing federal statutes against each other. A court cannot hold that the Commodity Exchange Act displaces IGRA under the Supremacy Clause because IGRA is itself federal. The court must instead determine whether Congress intended the CEA to implicitly repeal or supersede IGRA — a much harder legal standard, since implied repeals are disfavored.
Compact exclusivity is violated regardless of where the exchange is licensed
Many tribal-state gaming compacts grant tribes exclusive rights to offer sports wagering within their lands. Tribal gaming interests argue that a CFTC license does not override compact exclusivity, because compacts are approved by the Secretary of the Interior under federal law. Platforms operating under CFTC authority were not parties to those compacts and did not obtain the required authorization — meaning the exclusivity violation exists independent of the CFTC-vs-state fight.
State preemption track
CEA vs. state gambling law. Resolved by Supremacy Clause (federal overrides state). A 6th Circuit win for Kalshi would end state enforcement in Ohio and Tennessee and set persuasive precedent for other circuits.
Effect on tribal question: None, as a formal legal matter. The Supremacy Clause holding operates on federal-vs-state conflicts only.
Tribal sovereignty track
CEA vs. IGRA. Cannot be resolved by the Supremacy Clause — both are federal statutes. Court must ask whether Congress intended CEA to impliedly repeal IGRA's compact requirements, a high bar courts are reluctant to clear.
Effect of CFTC state win: Tribal cases proceed independently. The 9th Circuit ruling and any similar tribal suits are unaffected by state-preemption outcomes.
There is one significant risk to the tribal position: if a court rules that sports-event contracts are categorically financial instruments — not gaming — that characterization removes the predicate IGRA itself requires. IGRA only protects against gaming; if the product is not gaming, the tribal sovereignty argument loses its foundation. Both tracks share this upstream vulnerability.
Scenario A: Courts hold event contracts are financial instruments, not gaming
The strongest possible outcome for platforms. State enforcement is preempted by CEA; IGRA engagement fails because there is no qualifying gaming activity. Access opens broadly, including in most compact states. Geofencing of tribal lands becomes unnecessary. This outcome requires at least one circuit (likely the Sixth) to make an affirmative finding about product characterization — not just jurisdiction.
Scenario B: Courts hold CEA preempts state law but leave IGRA unresolved
A partial platform win. State enforcement is blocked in states where circuit courts apply the preemption ruling. But the tribal track survives and may require platforms to geofence tribal lands in compact states — particularly in California, New York, and New Mexico where active tribal litigation is proceeding. Access depends on where you are physically located, not just which state you live in.
Today, platform access depends on your location — not on how these cases resolve. Kalshi, Polymarket, and Robinhood remain available in most states. The tribal sovereignty challenge is a separate legal track that proceeds regardless of the Sixth or Fourth Circuit outcomes.
The most immediate practical implication: if you are physically located on tribal land — or in a state where tribal-state gaming compacts grant exclusive sports-betting rights — your access may be subject to a separate set of legal constraints that no CFTC license or state-preemption ruling resolves.
No geofencing order for tribal lands has been issued against any prediction market platform to date. The question is whether the Ninth Circuit, or a subsequent Supreme Court ruling, creates that requirement.
