Are prediction markets legal in California?
- Yes. CFTC-regulated event-contract exchanges like Kalshi are legal in 48 states plus D.C. under federal commodities law, including California. They are not classified as sports betting under California law because they trade as commodities derivatives on a federally-regulated venue.
Is Kalshi legal in California?
- Yes. Kalshi is a CFTC-regulated Designated Contract Market (DCM) and is open to California residents 21 and over. You can fund an account with a US bank or debit card and trade event contracts immediately.
What's the difference between Kalshi and Polymarket?
- Kalshi is US-regulated, USD-funded, and the easier choice for Californians. Polymarket is crypto-funded (USDC on Polygon), offers deeper political and global markets, and now serves US traders again through perpetual-futures products. Most Californians start on Kalshi.
Do I owe California taxes on prediction-market winnings?
- Yes. Net gains from CFTC event contracts are taxable as ordinary income at both the federal and California state level. Platforms issue 1099 forms above reporting thresholds. See our California taxes guide for full detail.
What's the minimum to start trading?
- In California, most platforms have no account minimum. Kalshi lets you fund as little as $5; Polymarket requires a USDC wallet but no minimum balance. Start small while you learn how contract pricing works.
How are prediction markets different from sportsbooks?
- Sportsbooks set odds, take a margin, and pay you against the house. Prediction markets are peer-to-peer exchanges where the price of a contract reflects the real-time probability of the outcome. And there is no house edge baked into the odds.
Does it matter if I'm in LA, SF, or San Diego?
- No. CFTC-regulated prediction markets are legal statewide in California: Los Angeles, San Francisco, San Diego, Sacramento, Fresno, the whole state. Funding works from any California bank or debit card.
