Ninth Circuit Rules Kalshi Sports Bets, Eyes Supreme Court
Appeals court rejects federal swap protection for Kalshi sports contracts, teeing up SCOTUS review.
The Ninth Circuit Court of Appeals has ruled that Kalshi's sports event contracts qualify as bets under state law, not federally protected swaps — a decision that, per Legal Sports Report, almost certainly sets up a landmark U.S. Supreme Court showdown over the future of prediction markets.
Why It Matters
For anyone holding a position on a prediction market platform, this ruling draws a hard line between financial derivatives and sports wagering — a distinction worth billions in regulatory exposure. If the Supreme Court affirms the Ninth Circuit, platforms like Kalshi face the prospect of operating under a patchwork of state gambling laws rather than the comparatively permissive federal Commodity Exchange Act framework. That outcome would hand state regulators and existing licensed sportsbooks a significant competitive advantage. Conversely, a reversal would potentially open every U.S. state to federally sanctioned sports prediction contracts, disrupting the licensed sportsbook industry overnight. Gambling — in any form — involves real financial risk, and this ruling underscores that the legal container matters as much as the product itself.
Context
Kalshi has argued that its event contracts are financial instruments regulated by the Commodity Futures Trading Commission (CFTC), insulating them from state gambling statutes. The Ninth Circuit's ruling, published as of September 2026 according to Legal Sports Report, rejected that framing for sports-specific contracts. The case crystallises a years-long tension between the CFTC's expansive view of its own jurisdiction and state gaming authorities who see prediction markets as unlicensed sportsbooks in a different wrapper.
What's Next
Kalshi's most plausible path forward is a petition for certiorari to the U.S. Supreme Court; if granted, a decision would likely reshape the entire U.S. prediction-market and sports-betting landscape. Watch for an expedited CFTC response and potential emergency relief motions in the interim.
