Supreme Court review becomes the only remaining move for Kalshi

Dani Lever, Kalshi's spokeswoman, said something careful in the hours after the Ninth Circuit handed down its unanimous ruling: the court had actually agreed with the Third Circuit on a fundamental point. Federal law prevents states from regulating trading on a federally licensed exchange. She is not wrong about that narrow proposition. She is describing the only ground Kalshi has left to stand on.

The Ninth Circuit's three-judge panel did not say that the Commodity Exchange Act is irrelevant to Kalshi's operations. It said the CEA likely does not pre-empt Nevada gaming regulations as applied specifically to sports event contracts. That word — likely — is doing structural work. The panel was evaluating whether the district court abused its discretion in dissolving a preliminary injunction. Judge Andrew Gordon's original dissolution survives because Kalshi could not show a sufficient likelihood of preemption. That is a procedural posture, not a final ruling on the merits. But procedural losses compound. Kalshi is now operating in a legal environment where two federal circuits have reached the same outcome through different reasoning, and that surface agreement obscures the circuit split that actually exists underneath it.

The Third Circuit held in April that Kalshi's sports-event contracts qualify as financial swaps and futures under the CEA, which would place them exclusively under CFTC jurisdiction. The Ninth Circuit declined to reach that characterization. The two courts are not contradicting each other on preemption doctrine — they are applying different analytical frameworks to the same products, which produces the same near-term outcome for Kalshi but leaves the foundational question unresolved. That unresolved question is the only reason a Supreme Court petition has any logic to it.

Nevada Gaming Control Board Chairman Mike Dreitzer read the ruling as total vindication. Bill Miller of the American Gaming Association called it a significant win for consumer protections. Those statements are accurate as far as they go. What they do not address is the CFTC's own posture, which Lever noted in her statement: the Commission is working to clarify its regulations. Whether that clarification, if it comes, would alter the preemption analysis under either circuit's framework is not answered anywhere in the public record. The courts assessed the CEA as it currently exists. A rulemaking that explicitly addressed sports event contracts would be litigated on different facts.

Connecticut filed suit the same week, seeking to ban Kalshi from operating unlicensed sports event contracts in the state. The suits are separate proceedings, but they draw from the same legal premise the Ninth Circuit just declined to foreclose: that state gaming frameworks reach what federal derivatives law does not fully cover.

The preemption question under the Commodity Exchange Act has two components that tend to collapse into each other in reporting on this litigation. The first is whether Kalshi's contracts are federally regulated instruments. The second is whether federal regulation of those instruments displaces state gaming authority. A court can answer yes to the first and still answer no to the second if it finds the state regulation operates in a distinct domain. That is approximately where the Ninth Circuit landed, and it is the gap that Kalshi needs the Supreme Court to close.
