California sports betting laws in 2026: still illegal, tribes target 2028, Kalshi enjoined

Sports betting is still illegal in California, online or in person. As of Nov. 9, 2026, the state has no licensed sportsbook and no regulator to license one. Nothing about it was on this year's ballot either. The newest development is in court, not in Sacramento: a federal judge in San Francisco has barred Kalshi from offering sports contracts on the land of two California tribes.

Our California guide covers the full legal background and which platforms are available in the state. This story covers what changed this fall and what is coming next.

Why legalizing it takes a statewide vote

California can't legalize sports betting by passing an ordinary bill. The state constitution limits gambling, Proposition 1A gave tribes the exclusive right to run casino gaming, and the Penal Code makes bookmaking a crime. Any change needs a constitutional amendment approved by voters. In November 2022 voters turned down both options they were offered. Proposition 26 would have allowed in-person betting at tribal casinos and racetracks. Proposition 27, backed by national sportsbook operators, would have allowed online betting. Both failed by wide margins.

The California Nations Indian Gaming Association is now aiming for 2028. Chairman James Siva told CDC Gaming this summer that "2028 is the goal." Siva has said the tribes plan to cover both retail and online betting, not just in-person betting as in 2022. Legal Sports Report reported that the tribes have kept polling voters since 2022, including a round in June. It also reported that they plan to pitch a tribally regulated market as a contrast to prediction markets. California is still the largest state without legal sports betting.

The Kalshi ruling

While the ballot plan waits, the fight has moved to prediction markets. These are federally regulated exchanges where users trade contracts on game outcomes. On Sept. 16 the Ninth Circuit ruled in Blue Lake Rancheria v. Kalshi that Kalshi's sports contracts are likely unauthorized gaming when traded from the plaintiff tribes' land. Kalshi has since switched those contracts off on three tribal reservations.

The district court followed up last week. The Block reported that U.S. District Judge Jacqueline Scott Corley granted a preliminary injunction. It bars Kalshi from offering sports event contracts on the lands of Blue Lake Rancheria and the Chicken Ranch Rancheria of Me-Wuk Indians. Attorney General Rob Bonta has backed the tribes in the litigation.

The Ninth Circuit ruling and the injunction both apply to tribal land, not the rest of California. Neither one makes sports betting legal anywhere in the state, and neither one bans prediction markets statewide.

Where that leaves Warriors fans

It is not legal to bet on sports in California. No California casino, card room or app can take a sports bet, and no offshore site is licensed to serve the state. Several CFTC-regulated prediction exchanges are available to most California residents, including Novig, Kalshi and Polymarket US. On these exchanges you take a position at a price set by other traders, not by a house. The minimum age is 21.

What happens next depends on the courts and on whether the tribes' 2028 measure makes the ballot. Further rulings in the Kalshi case could change what is offered and where. Our California page is rechecked after every ruling, and Warriors coverage stays on our team page.
