What this means for California traders
Kalshi and Polymarket are regulated at the federal level by the CFTC, so their college football markets are generally available across the US, including California. A small number of states have contested federally-regulated sports event contracts, which is why some entries read as limited rather than fully available.
ProphetX is a peer-to-peer sports prediction exchange that operates state by state, so its availability in California is not available. Where a platform is available, you can sign up with our code and trade college football futures like the national title, Heisman and conference winners.
Redshirt Analytics is not a law firm and this is not legal advice. Rules change; always confirm current availability with each platform for your location before funding an account.
