California Prediction Markets: Best Prediction Market Apps in CA

California’s prediction market boom is largely driven by the fact that the state doesn’t offer licensed betting options for sports. With traditional sports wagering still not legalized, residents have increasingly turned to prediction platforms that operate under a federal designation rather than state licensing. The article highlights several available apps, including Novig, launched in August 2026, focused exclusively on sports with live trading and market-driven pricing, but restricted to users 21+. It also covers Polymarket’s January 2026 U.S. relaunch after CFTC designation, Kalshi’s CFTC contract-market status since November 2020, OG.com’s event contracts, and notes that users must manually enter promo codes for some offers.
