California Sports Betting: History, Current Laws, and What’s Next in 2026
California is the biggest sports betting market that doesn’t actually exist. With nearly 40 million residents, some of the most passionate fan bases in the country, and neighboring states like Nevada and Arizona already running full-blown mobile sportsbooks, you’d think the Golden State would have legalized wagering years ago. Instead, California remains one of the largest holdout states in the nation, and getting there has turned into one of the messiest, most expensive political fights in American ballot history. Here’s how California got to this point, where things actually stand heading into 2026, and what it would realistically take to change.
The Road to 2022: Why California Never Just Passed a Law
Most states that legalized sports betting after the Supreme Court struck down PASPA in 2018 did it the simple way — a bill worked its way through the legislature, a governor signed it, and sportsbooks opened. California can’t do that. Because gambling expansion in the state requires a constitutional amendment, any change has to go through the initiative process and win approval directly from voters. That single structural quirk is a huge part of why California has struggled for nearly a decade to get anywhere.
Early attempts to legalize sports betting go back to around 2017, before states even had the option to regulate it themselves. Card rooms tried to get their own version onto the ballot in 2020 but couldn’t gather enough signatures. Tribal groups and commercial operators each began building their own competing visions for what a legal market should look like, and those visions didn’t line up.
By 2022, two very different proposals had qualified for the November ballot. Proposition 26, backed by California’s gaming tribes, would have allowed retail-only sports betting at tribal casinos and licensed horse racing tracks, with no online component at all. It also would have opened the door for tribal casinos to add craps and roulette to their game offerings. Proposition 27, backed by national commercial operators including DraftKings, FanDuel, and BetMGM, took the opposite approach: statewide online and mobile sports betting, with no retail component.
The two campaigns ended up spending more than $450 million combined, making it the most expensive ballot measure fight in U.S. history on any topic, in any state. Tribes poured over $200 million into defeating Prop 27, viewing mobile betting as a direct threat to their existing casino monopoly, while commercial operators spent heavily trying to get their own measure across the finish line. The result was a saturation of dueling attack ads that left voters confused and skeptical of both options. When the votes came in, both measures failed by lopsided margins — Prop 26 lost by roughly a two-to-one margin, and Prop 27 fared even worse, going down by more than 80% opposition in some counts.
California Sports Betting – How to Bet Today
Where Things Stand Heading Into 2026
Fast forward to today, and the short answer is simple: sports betting is still completely illegal in California, in every form. There are no licensed retail sportsbooks at tribal casinos, no legal online or mobile betting apps, and no path currently open on the ballot. Companies like DraftKings, FanDuel, BetMGM, and Caesars don’t offer traditional sports wagering anywhere in the state.
Since the 2022 defeat, a few groups have tried to revive the conversation. The Pala Band of Mission Indians floated its own online betting initiative for the 2024 cycle before backing away after pushback from other tribes. Other operator-aligned groups, including Eagle 1 Acquisitions, filed additional proposals aimed at bringing tribes and commercial sportsbooks to the table together, but the California Nations Indian Gaming Association voted unanimously to oppose those third-party efforts, and without tribal buy-in, no measure has a realistic shot at passing.
More recently, DraftKings and FanDuel have floated a different approach — a single tribal-led entity that would oversee online sports betting statewide, paired with guaranteed annual payments to each of California’s 109 federally recognized tribes. The idea is meant to bridge the divide that sank Props 26 and 27 by putting tribes in the driver’s seat rather than competing against them. As of early 2026, though, no formal agreement has been finalized, and tribal leaders have publicly said they don’t plan to put anything on the 2026 ballot. Most industry watchers now consider November 2028 the earliest realistic window for a new attempt, and even that depends on stakeholders actually reaching consensus rather than repeating the expensive stalemate from 2022.
The Rules Are Actually Getting Tighter, Not Looser
If anything, California has moved to close off the workarounds people were using instead of legal sports betting, rather than open new ones. In July 2025, Attorney General Rob Bonta issued a formal legal opinion concluding that paid daily fantasy sports contests count as a form of sports wagering under California law, putting operators like PrizePicks and Underdog on shaky legal footing. Many of them responded by shifting to peer-to-peer contest formats to try to stay compliant.
Then, in October 2025, Governor Gavin Newsom signed Assembly Bill 831, which took effect January 1, 2026, and banned so-called sweepstakes-style sportsbooks that use a dual-currency model to hand out cash prizes. That law pushed platforms like Fliff out of the California market entirely, closing off a gray-area option a lot of residents had been using to simulate real-money sports betting. Regulators have also started paying closer attention to prediction markets like Kalshi and Polymarket that let users bet on sports outcomes through a different legal wrapper, and lawmakers introduced bills in early 2026 aimed at reining those in as well.
What’s Actually Legal for California Sports Fans
None of this means California is a total dead zone for sports wagering. A few legal avenues remain open:
- Horse racing — Pari-mutuel wagering on horse races is legal and can be done online through licensed platforms like TVG and TwinSpires, since horse racing operates under a separate legal framework from traditional sports betting.
- Tribal casino gaming — California’s tribal casinos remain a massive industry, though they currently offer traditional casino games rather than sports wagering.
- Card rooms — Licensed card rooms operate legally across the state, though they’re limited to card games rather than sports betting.
- The California Lottery — Standard state lottery games remain unaffected by any of this.
Daily fantasy sports and sweepstakes-style apps exist in a much shakier position following the Attorney General’s 2025 opinion and the new sweepstakes ban, so anyone using those platforms should understand the legal ground has shifted under them recently.
Some California residents turn to offshore sportsbooks that accept U.S. players despite not being licensed anywhere in the country. These sites operate completely outside state or federal regulation, which means none of the consumer protections that come with a licensed market — things like dispute resolution, responsible gambling tools, or guaranteed payouts — apply to them.
The Bottom Line
California’s sports betting saga is a case study in how gambling expansion can stall out even in a state desperate for the tax revenue and consumer demand that usually drives legalization elsewhere. The core problem has never really been whether Californians want to bet on sports — it’s that tribes, card rooms, and commercial operators all want fundamentally different markets, and the state’s ballot-measure requirement means all three groups essentially have to agree, or at least stop actively fighting each other, before anything can pass. Until that happens, California will keep watching neighboring states cash in on a market it hasn’t figured out how to open, with 2028 now the commonly cited target for the next real attempt.
