California's prediction-market guide.
Prediction markets are legal in California. Every platform on this page is CFTC-regulated under federal commodities law — which means they bypass California's sports-betting ban entirely. Here's where to start, what's tradable, and how taxes work.

Updated Jul 3, 2026California prediction-market FAQ
Are prediction markets legal in California?
Yes. CFTC-regulated event-contract platforms like Kalshi, Sleeper, Chalkboard, Novig, and Polymarket's iOS app operate legally in California under federal commodities law. They are not classified as gambling, so California's sports-betting ban does not apply.
Which platform is best for California residents?
OG by Crypto.com is our #1 overall pick for California traders — largest welcome bonus and broad device support. Polymarket's US iOS app is #2 for the deepest live in-play book. Kalshi is #3, the broadest CFTC-regulated platform and best for politics. Rebet is #4 for social-first traders. Chalkboard, Novig, and Sleeper round out sports props, sharp peer-to-peer markets, and group-chat trading.
Do I have to pay California state tax on prediction-market winnings?
Yes. Prediction-market profits are taxable as ordinary income at both the federal and California state levels. Platforms typically issue a 1099 if your net winnings exceed reporting thresholds. See our prediction-market taxes guide for details.
Can I use Polymarket in California?
Yes — Polymarket relaunched a CFTC-regulated US app available on iPhone in 2025, and it is fully legal for California residents. The web version remains restricted in the US.
What is the difference between prediction markets and sports betting?
Prediction markets are CFTC-regulated event contracts, classified as financial derivatives — not gambling. Sports betting is regulated state-by-state and remains illegal in California. Prediction markets bypass that ban because they fall under federal commodities law.
