Kalshi faces intensifying legal and regulatory pressure as state and federal authorities challenge its business model. While the company maintains its markets are financial instruments under CFTC oversight, a unanimous 3-0 ruling by the Ninth Circuit Court of Appeals has determined that its sports event contracts are likely sports bets rather than federally regulated swaps. This decision allows states to enforce gaming laws against the platform and creates a judicial split with the Third Circuit. To resolve this jurisdictional conflict, New Jersey has petitioned the U.S. Supreme Court to determine whether prediction markets should be regulated as gambling by states or as financial derivatives by the CFTC. New Jersey is specifically seeking to overturn a Third Circuit decision that favored Kalshi. Attorney General Jennifer Davenport argues that the Commodity Exchange Act does not grant the CFTC exclusive authority to override state police powers regarding gambling, consumer protection, and age restrictions. ~~This legal battle has expanded to include Arizona, Massachusetts, New York, and Connecticut.

Non-compliance carries a $500,000 daily fine. Additionally, Kalshi faces private litigation from FlightAware, which alleges the platform used its data and trademark without permission to settle wagers on flight cancellations. Despite these challenges, Kalshi has expanded into regulated crypto derivatives and reported monthly notional trading of approximately $40 billion in August.
