Is Gambling Legal in California?

California’s position in eight figures, each one taken from a statute, a regulator or the Secretary of State.

• 67 tribal casinos: run by 64 tribes, according to the California Gambling Control Commission. Tribal land is the only place in the state where Slots are legal.
• 17.7% yes: the vote for Proposition 27, statewide online sports betting, in November 2022.
• 33.0% yes: the vote for Proposition 26, in-person sports betting at tribal casinos and racetracks, on the same ballot.
• $25,000 fine: the top penalty under Penal Code 337o for running an online sweepstakes casino, along with up to a year in county jail.
• 77 to 0: the Assembly vote on AB 831, the sweepstakes ban. The Senate passed it 36 to 0.
• 21 years old: the minimum age to walk onto a licensed cardroom floor.
• 18 years old: the minimum age to buy a California Lottery ticket or bet on a horse race.
• Zero gambling measures: on the November 3, 2026 statewide ballot.

The sources for all eight are listed at the foot of the page.

That’s the law as it stands in September 2026. The sections below explain each row, starting with why nobody can simply hand out online casino licenses here.

California gambling laws give nobody a license to run an online casino, so every real-money casino site taking California players is doing it without one. That isn’t a gap a regulator is about to fill. It’s written into the state constitution.

The Constitution Rules Out Nevada-Style Casinos

Article IV, Section 19 of the California Constitution says the Legislature “has no power to authorize, and shall prohibit, casinos of the type currently operating in Nevada and New Jersey.” Lawmakers can’t license commercial online casinos around that sentence with an ordinary bill. It would take a constitutional amendment, and that means a statewide vote.

The same section lists the exceptions, and they explain the whole market: horse racing and betting on it, charity Bingo, nonprofit raffles, the California State Lottery, and gaming on tribal land under compacts.

What the Penal Code Says About Players

Penal Code 330 sits in a chapter first enacted in 1872. It names the banned games, including Roulette and “twenty-one,” and adds “any banking or percentage game played with cards, dice, or any device, for money.” It covers “every person who plays or bets at or against any of those prohibited games,” not only the person running the game.

A violation is a misdemeanor, with a fine of $100 to $1,000, up to six months in county jail, or both. The section was written long before the internet and says nothing about where a game is hosted.

In person, quite a lot is legal. But every product has its own box and its own regulator, and none of those boxes is a commercial casino.

Tribal Casinos

Tribal land is the only place in California where you’ll find Slots and house-banked table games. Section 19(f) of the constitution lets the Governor sign compacts, and under them “slot machines, lottery games, and banking and percentage card games are hereby permitted to be conducted and operated on tribal lands.”

The California Gambling Control Commission counts 64 tribes running 67 casinos. Most game under a tribal-state compact, 62 tribes and 48 of them with casinos, and 19 tribes operate under federal Secretarial Procedures issued by the US Department of the Interior when no compact is in effect.

Cardrooms

A cardroom can’t bank a game. Players bet against each other, which is why Poker has always been legal here, and a rotating player-dealer position lets rooms offer Blackjack-style games without the house taking the other side. Under Business and Professions Code 19921, nobody under 21 may enter a licensed gambling establishment’s gaming floor.

That model spent 2026 in court. On July 8, the San Francisco Superior Court issued a writ in California Gaming Association v. Bonta blocking the Bureau of Gambling Control’s rules on Blackjack and player-dealer games. On July 10 it ruled that the Bureau “lacks statutory authority to issue the regulations.” The Bureau has appealed, so for now the rooms keep dealing.

The Lottery, Horse Racing and Charity Games

The California State Lottery is authorized by the constitution, and state law bars selling a ticket to anyone under 18. Horse racing is overseen by the California Horse Racing Board, and its rules say no minor may buy or cash a parimutuel ticket.

Eligible nonprofits can run raffles as long as at least 90 percent of the gross receipts go to charitable purposes in California, and cities and counties can allow Bingo for charity.

None of the three is legal online, and sports betting isn’t legal in person either. California voters had two chances to change that in November 2022 and said no both times.

How Propositions 26 and 27 Lost

Proposition 26 would have allowed in-person sports betting at tribal casinos and racetracks. It drew 3,514,597 yes votes, 33.0%, against 7,129,127 no votes. Proposition 27, statewide online sports betting, did far worse at 17.7%, losing 8,849,206 to 1,906,342, according to the Secretary of State’s Statement of Vote.

Nothing on the November 3, 2026 ballot touches gambling, so there’s no vote on sports betting this year.

Where You Can Play Legally Instead

If you want a licensed online casino, you have to be physically inside a state that regulates one, such as New Jersey, Pennsylvania or Michigan. For the national picture, see our US online gambling laws guide.

Because nothing is legal online in California, offshore sites target players here hard. They’ll take your deposit, but they hold no California license and offer no US consumer protection. If they hold back a withdrawal or void your winnings, you have almost no recourse, and there’s no state self-exclusion list they have to honor.

There’s also no California regulator to complain to. The Gambling Control Commission and the Bureau of Gambling Control deal with cardrooms and tribal compacts, and the state has never licensed an online casino for them to oversee.

So treat a real-money casino ad aimed at Californians as a warning sign in itself. The missing legal option is exactly why these sites are risky. It isn’t a reason to use them.

Online sweepstakes casinos are now illegal to run in California. Assembly Bill 831 was approved by the Governor on October 11, 2025, became Chapter 623 of the Statutes of 2025, and took effect on January 1, 2026.

What AB 831 Bans

The bill added Penal Code 337o, which makes it unlawful “to operate, conduct, or offer an online sweepstakes game in this state.” It’s aimed at the dual-currency model: coins you buy or get free, games that simulate Slots, Video Poker, Blackjack, Roulette, Bingo or sports wagering, and a route to cash or cash-equivalent prizes.

It reaches the businesses around the casino as well. Any “financial institution, payment processor, geolocation provider, gaming content supplier, platform provider, or media affiliate” that knowingly and willfully supports one is breaking the law too. The penalty is a misdemeanor, with a fine of $1,000 to $25,000, up to a year in county jail, or both.

What It Leaves Alone

The statute says it doesn’t make unlawful a game “that does not award cash prizes or cash equivalents,” and it leaves ordinary marketing sweepstakes alone. That’s why the sweepstakes brands we review list California among the states where you can’t play for prizes.

It wasn’t close, either. AB 831 passed the Assembly 77 to 0 and the Senate 36 to 0.

The legal gambling age in California depends on what you’re playing. Here’s how it breaks down.

Where to Get Help in California

California runs its own problem gambling helpline through the Office of Problem Gambling at the California Department of Public Health. Call 1-800-GAMBLER (1-800-426-2537) to reach a counselor any time, day or night, text “SUPPORT” to 53342, or use the chat at 800gambler.chat. It’s free and confidential.

The national line works from California too. You can call or text 1-800-MY-RESET, the National Problem Gambling Helpline run by the National Council on Problem Gambling. You don’t have to be in crisis to reach out, and doing it early is easier than most people expect.

Not soon. A legal online casino run by commercial operators would run straight into the constitution’s ban on Nevada-style casinos, and changing that takes a statewide vote.

The last vote shows how steep that climb is. Online sports betting drew 17.7% in 2022, and the November 3, 2026 ballot carries no gambling question at all.

If that changes, this page changes with it. I update the status when a law actually passes or a measure qualifies for the ballot, not when a bill is merely filed.

Winnings are taxable even though you can’t gamble online here. The IRS treats gambling winnings as income, and a casino, racetrack or lottery issues a federal Form W-2G on larger payouts. The minimum reporting threshold for payments made in 2026 is $2,000.

California taxes them too, with one big exception. The Franchise Tax Board says all gambling winnings are taxable, including winnings from lotteries, raffles, horse races and casinos, but it does not tax winnings from the California Lottery, including SuperLotto, Powerball and Mega Millions.

Losses only help up to what you won. In the Franchise Tax Board’s own example, someone who won $10,000 and lost $15,000 can deduct $10,000, so keep your own records of both.
