Conflicting Appellate Rulings Push Kalshi Event Contract Dispute to Supreme Court
A split between federal appellate courts has positioned Kalshi's sports event trading contracts for a decisive U.S. Supreme Court review.

A legal battle over prediction market operator Kalshi is heading to the U.S. Supreme Court following contradictory decisions from the Third and Ninth Circuit Courts of Appeals. The dispute centers on whether federal commodities law preempts state-level sports gambling regulations.
The emerging circuit split provides state authorities with the legal foundation to challenge previous rulings that shielded Kalshi's event contracts from local gaming prohibitions. The outcome will decide the regulatory boundaries for federally registered prediction markets.
A Supreme Court resolution will carry significant consequences for prediction platforms, clarifying whether decentralized and regulated derivatives venues can offer sports and event contracts nationwide without individual state licenses.
Key takeaways
- Ninth and Third Circuits split on state gaming laws versus Kalshi contracts.
- The legal dispute is positioned for U.S. Supreme Court consideration.
- Final ruling will define federal vs. state authority over prediction markets.
