How Does Polymarket Work in California
Polymarket functions as a decentralized exchange where users buy and sell “shares” in the outcome of future events. It is a legal workaround to sports betting because it is classified as a prediction market regulated by the Commodity Futures Trading Commission (CFTC).
Instead of betting against a “house” (like a sportsbook), you are trading “event contracts” with other users. If you think the Los Angeles Lakers will win their next game, you buy “Yes” shares. If they win, each share settles at $1.00. This structure mirrors a financial derivatives market, which falls under federal jurisdiction, often preempting restrictive state-level gambling laws.
Polymarket as a Legal Alternative to California Sportsbooks
Since California has yet to legalize mobile sportsbooks like DraftKings or FanDuel, Polymarket has become the go-to destination for local sports fans. Because these are traded as “event contracts,” you can legally take positions on your favorite local teams.
