CFTC-regulated prediction markets are available in California. As the largest state by population, CA represents a major market for platforms like Kalshi and Polymarket.
Prediction markets (also called event contracts) let you trade on the outcome of real-world events — elections, economic indicators, weather, and more. Unlike sports betting, these are CFTC-regulated financial instruments traded on designated contract markets.
Since California does not have legal online sports betting, prediction markets offer one of the few legal ways to trade on event outcomes. CFTC-regulated platforms are available regardless of state sports betting laws.
