A federal appeals court delivered a sharp rebuke Friday to Kalshi, the prediction market platform that claimed federal law shields it from state gambling regulators. The ruling means states retain the power to enforce their sports betting laws against the company — and deepens a split among federal courts that could force the Supreme Court to settle the question.
Kalshi operates digital markets where users trade “event contracts” — bets on everything from election outcomes to weather patterns. When the platform launched sports betting contracts last year, state regulators in Ohio and Tennessee moved to enforce their gambling laws. Kalshi sued, arguing the Commodity Futures Trading Commission has “exclusive jurisdiction” over its products under federal commodities law.
Court Rejects Federal Shield Claim
The Sixth Circuit panel rejected that argument on two grounds. First, the court found Kalshi’s sports contracts don’t qualify as “swaps” — the type of financial derivative that falls under exclusive federal oversight. Second, even if they were swaps, the Commodity Exchange Act doesn’t prevent states from regulating gambling within their borders.
The decision hands ammunition to attorneys general in conservative states who’ve watched prediction markets explode without clear regulatory authority. These platforms operate in a gray zone: sophisticated enough to attract venture capital and Wall Street interest, but functionally identical to the sports betting apps states carefully regulate.
Circuit Split Sets Up Possible Supreme Court Review
Friday’s ruling conflicts with decisions from other federal appeals courts, creating the kind of legal split that often prompts Supreme Court intervention. For states trying to protect residents from predatory gambling operations — or simply collect tax revenue from betting activity — the uncertainty is costly.
Kalshi’s business model depends on the federal preemption argument. Without it, the company faces a patchwork of state regulations that could force it to obtain gambling licenses, pay state taxes, and comply with consumer protection rules in all 50 states. That’s expensive and cuts into the platform’s appeal to investors who valued regulatory arbitrage as much as the technology itself.
The company will likely appeal. Watch for a petition asking the Supreme Court to resolve whether federal commodities law really creates a nationwide exemption from state gambling enforcement — or whether states retain the police powers they’ve exercised since before the Constitution was ratified.
Key Points
- Federal appeals court rejected Kalshi’s claim that commodities law preempts state gambling regulation of its sports betting contracts
- Ruling conflicts with other federal circuits, setting up potential Supreme Court review of state regulatory authority
- Decision forces prediction market platforms to potentially comply with 50 different state gambling regimes instead of federal-only oversight
