Frequently asked questions

What's the best prediction market app in California in 2026?

For most California traders, Polymarket is our top pick: it has the deepest politics and news liquidity in the world, low trading fees, and a $25 trading bonus on a $10 deposit with code VENICE (18+). Robinhood ranks second for traders who already hold a brokerage account there, and Kalshi is our #3 pick — the best choice if you want the widest market catalog. The platforms argue that federal commodities law overrides California gambling statutes for event contracts traded on a Designated Contract Market; for sports contracts the courts are still deciding.

How do you rank these prediction market apps?

We score apps on six weighted criteria: California availability, market depth and liquidity, fees and payout speed, app/UX quality, regulatory standing (CFTC vs offshore), and welcome-bonus terms. Rankings are reviewed monthly and re-tested with real deposits. We never accept payment to influence rank order — only the affiliate links inside each card are monetized, as disclosed on every page.

Are these prediction market apps legal for California residents?

Every app shown here is a CFTC-regulated exchange that accepts eligible Californians, or is flagged as not available in California (Rebet). The platforms argue federal commodities law overrides California's gambling statutes; for sports contracts the courts are still deciding. Eligible Californians can sign up today (status: Available, dispute pending, as of 13 October 2026), except Kalshi on three tribes' lands.
