California Sports Betting

Banking and Payouts

Cryptocurrency is the primary banking method at every book on this page, and it is the only method that produces fast withdrawals. Bitcoin is universally supported. Most books also handle Litecoin, Ethereum, Bitcoin Cash and a range of other coins, with BetOnline, SportsBetting.ag and BetUS supporting the widest lists.

Credit and debit card deposits are accepted at most of these books, but they fail frequently because U.S. card issuers block gambling-coded transactions. No book on this page returns withdrawals to a credit card. Non-crypto payout methods include courier check, bank wire, money order and peer-to-peer transfer, and they typically take one to three weeks and carry minimums that are often $500 or higher.

Every book requires identity verification before a first withdrawal. Bettors should complete verification when the account is opened rather than when a payout is requested, because verification delays are the most common cause of slow first withdrawals.

Bonuses and Rollover

Offshore welcome bonuses are advertised aggressively and are worth considerably less than the headline number suggests. A bonus is credited as non-withdrawable funds subject to a rollover requirement, meaning a multiple of the bonus, and often the deposit as well, must be wagered before anything can be withdrawn.

Rollover multiples on sportsbook bonuses at these books commonly range from about 5x to 14x, and higher percentage bonuses carry the highest multiples. Many bonuses also exclude low-odds wagers from counting toward rollover, which forces bettors into higher-variance bets to clear the requirement.

The practical guidance is to calculate total required action before accepting any bonus, and to decline the bonus if the number is larger than a bettor intends to wager anyway. Bonus funds that cannot be cleared are not money.

Warning Signs and Books to Avoid

New offshore brands appear constantly, and the failure rate is high. Signals worth treating as disqualifying include no verifiable operating history, no named licensing jurisdiction, bonus offers far above the market, no published withdrawal timelines, customer support available only through a web form, and a pattern of unresolved nonpayment complaints on independent betting forums.

Bettors should also be skeptical of any site claiming to be legal or licensed in California. No sportsbook holds a California license, because California issues none.

Offshore Books Compared With the Legal Alternatives

Californians who want exposure to sports outcomes have three practical options, and they carry different risk profiles.

Offshore sportsbooks offer the most familiar product, the deepest markets and the widest range of bet types, with no regulatory protection and an unresolved question about the bettor's own legal exposure.

Federally regulated prediction markets offer sports event contracts through exchanges overseen by the Commodity Futures Trading Commission. The product is more limited and the pricing model is different, but the operator is federally registered. The trade-off is that the legal status of sports event contracts is under active appellate review.

Pari-mutuel horse racing is the only form of sports wagering in California that is unambiguously legal, licensed by the state and available online through regulated operators. The trade-off is that it covers one sport.

California Sports Betting Laws Explained

California gambling law is built on a general prohibition with specific carve-outs. Anything not expressly authorized is illegal. Sports betting has never been expressly authorized.

Penal Code Section 337a

Section 337a is the central statute. It criminalizes bookmaking and pool selling, occupying any place for the purpose of recording or registering bets, and receiving, holding or forwarding money to be wagered on the result of any contest. It applies to sporting events and to essentially any contingent event.

The statute is a wobbler, meaning it can be charged as a misdemeanor or a felony. A first offense carries up to a year in county jail and a fine of up to $5,000. Subsequent or aggravated offenses can be charged as felonies.

Section 337a predates the internet by decades, and its application to online wagering has never been definitively settled by a California appellate court. That gap is the source of most of the disagreement about individual bettor liability.

Penal Code Section 330

Section 330 prohibits banked and percentage games, meaning games where the house holds a stake in the outcome. It is the statute that underlies the long-running dispute between tribal casinos and card rooms over which table games card rooms may legally spread. It is not a sports betting statute, but it defines the boundary of what non-tribal operators can offer in California, and that boundary is central to the political fight over legalization.

Penal Code Section 337o and Assembly Bill 831

Gov. Gavin Newsom signed AB 831 on Oct. 11, 2025, and it took effect Jan. 1, 2026. The law added Section 337o to the Penal Code and made it unlawful to operate, conduct or offer an online sweepstakes game in California that uses a dual-currency model, simulates casino-style or sports wagering play and awards cash or cash equivalents.

The provision that drew the most attention from the industry extends liability beyond operators. Under AB 831, financial institutions, payment processors, geolocation providers, gaming content suppliers, platform providers and media affiliates that knowingly and willfully support a prohibited sweepstakes operation can be charged. Violations are misdemeanors punishable by fines of $1,000 to $25,000, up to a year in county jail, or both, and each violation is a separate count.

AB 831 targets sweepstakes products specifically. It does not address offshore sportsbooks. Its significance is that it demonstrates California is now willing to write affiliate and vendor liability directly into gambling statutes.

The California Constitution and Tribal Exclusivity

Article IV, Section 19 of the California Constitution governs gambling in the state. Proposition 1A, approved by voters in 2000, amended it to authorize tribal governments to conduct Class III gaming, meaning slot machines and banked card games, on tribal land under compacts negotiated with the state.

That exclusivity is the structural fact that shapes everything else. Under the federal Indian Gaming Regulatory Act and the compacts negotiated under it, California's federally recognized tribes hold exclusivity over Class III gaming, a category that includes sports betting. Any framework that gives sports betting to a non-tribal operator cuts into that exclusivity, which is why tribal governments have opposed every commercial proposal put forward.

Why Legalization Requires a Constitutional Amendment

Because gambling authority is written into the state constitution, the Legislature cannot legalize sports betting by ordinary statute. A constitutional amendment is required, and there are two routes to one.

The Legislature can place an amendment on the ballot by a two-thirds vote of both chambers, which is what SCA 6 attempted in 2020 before it died at the deadline. Alternatively, a citizens' initiative can qualify by gathering valid signatures from registered voters equal to 8 percent of the votes cast in the last gubernatorial election, which is the route Propositions 26 and 27 took.

Either way, the measure then goes to a statewide vote. After a successful vote, tribal-state compacts would need to be renegotiated and ratified, and a regulator would need to write and implement rules. That sequence is why industry observers describe the gap between a successful ballot measure and a live market in years rather than months.

Who Would Regulate Sports Betting in California

Both 2022 measures identified the Bureau of Gambling Control, a division of the California Department of Justice, as the regulator. The California Gambling Control Commission licenses and oversees card rooms and tribal gaming operations and would likely have a role in any framework. Neither agency currently has authority over sports wagering, because none exists to regulate.

Legal Gambling Age in California

The minimum age depends on the activity. Pari-mutuel horse racing and the California State Lottery are open to anyone 18 or older. Tribal casinos set their own minimums, generally 18 or 21 depending on whether alcohol is served. Both 2022 sports betting measures would have set the minimum at 21, and any future framework is expected to do the same. Prediction markets require users to be 18 or older.

Timeline of California Sports Betting Laws, Bills and Ballot Measures

Before 2018: California Under PASPA

The federal Professional and Amateur Sports Protection Act barred states other than Nevada from authorizing sports betting. California had no independent path to legalization, and the question was largely theoretical.

2017: ACA 18

Assemblyman Adam Gray introduced Assembly Constitutional Amendment 18, an attempt to get California positioned ahead of a possible PASPA repeal. Tribal interests declined to engage and the measure went nowhere.

2018: PASPA Struck Down

The U.S. Supreme Court struck down PASPA in Murphy v. NCAA in May 2018, making sports betting a state-level decision. California became the largest prize in the country overnight.

2019: ACA 16 and SCA 6

Sen. Bill Dodd and Gray introduced companion constitutional amendments in June 2019 to place a sports betting question before voters. The measures were intentionally skeletal, with the details to be negotiated with stakeholders. Rather than come to the table, tribal governments responded by filing their own ballot initiative limited to retail sports betting at tribal casinos and horse racing tracks.

2020: SCA 6 Advances and Dies

An informational hearing in January 2020 produced little movement. The pandemic then halted signature gathering on the tribal initiative, and a $54 billion state budget deficit gave lawmakers an opening to revive the legislative route. Dodd and Gray amended SCA 6 with implementation language authorizing retail and online sports betting at tribal casinos and racetracks, with card rooms offered legal clarity but no sports betting.

Tribal leaders opposed it forcefully. SCA 6 cleared the Senate Governmental Organization Committee on a 9 to 3 vote but needed two-thirds approval in both chambers before a late June deadline to qualify for the ballot. It never got a floor vote and died.

2021: Four Initiatives and the Signature War

The tribal coalition won a court fight for additional signature-gathering time and certified just over a million valid signatures, qualifying its retail-only measure for the November 2022 ballot. Two additional proposals then emerged, one backed by card rooms and one by commercial sportsbook operators, both contemplating online betting. A November 2021 poll showed weak voter support for online sports betting, an early indicator of what was coming.

2022: Propositions 26 and 27 Both Fail

The card room measure collapsed in April 2022 after litigation and tribal opposition. The commercial operator measure qualified in June when the secretary of state certified more than a million signatures. Californians voted on both remaining measures in November.

Proposition 26 would have authorized in-person sports betting at tribal casinos and licensed racetracks and permitted tribal casinos to offer roulette and dice games. It contained no online provision. Voters rejected it by more than 2 to 1.

Proposition 27 would have authorized statewide online sports betting run largely by commercial operators partnered with tribes, with revenue directed toward homelessness programs. It was backed by DraftKings, FanDuel and BetMGM. Roughly 82 percent of voters rejected it, one of the widest margins for a major measure in modern California ballot history.

Combined spending on the two campaigns exceeded $400 million, making it the most expensive ballot fight in state history at the time.

2023: Initiatives 23-0030 and 23-0031

Two initiatives filed with the attorney general's office, the Sports Wagering Regulation and Tribal Gaming Protection Act and the Tribal Gaming Protection Act, proposed a tribally run sports betting industry and a framework for compact negotiation. Both were withdrawn after tribal organizations objected that they had not been consulted. In a letter to the attorney general the same year, the California Nations Indian Gaming Association characterized daily fantasy pick'em games as illegal sports wagering, an early move in what became the 2025 fantasy sports fight.

2024: SB 549

Newsom signed Senate Bill 549, the Tribal Nations Access to Justice Act, in September 2024. The bill by former Sen. Josh Newman gave California's gaming tribes a one-time grant of standing to sue card rooms in state court over whether the games they spread constitute illegal house-banked play. Tribes had been repeatedly dismissed from earlier suits on the grounds that as sovereign governments they lacked standing.

The same year, proponents of new sports betting initiatives called off their efforts, and industry figures including Indian Gaming Association conference chair Victor Rocha began publicly describing 2028 as the realistic target.

January 2025: Tribes Rule Out 2026

CNIGA confirmed it would not pursue a ballot initiative for the 2026 election. By April, reports emerged of constructive discussions between tribal governments and commercial sportsbook operators, with DraftKings and FanDuel pitching a revenue-sharing partnership model designed to address tribal control concerns.

July 2025: The Attorney General's DFS Opinion

Bonta released Opinion No. 23-1001 on July 3, 2025, concluding that paid daily fantasy sports contests violate Section 337a because participants place bets on the outcomes of sporting events. The 33-page opinion drew no distinction between formats, covering pick'em, draft-style and peer-to-peer contests alike.

The opinion answered a 2023 request from former Sen. Scott Wilk and a follow-up from Assemblyman Tom Lackey. Underdog had sued to block its release, and a Sacramento Superior Court judge declined to intervene, noting that attorney general opinions are advisory and do not carry the force of law. Newsom's office publicly disagreed with the conclusion. Bonta told reporters that enforcement was the next step.

October 2025: AB 831 Signed and the Card Room Suit Dismissed

Newsom signed AB 831 on Oct. 11, 2025, after unanimous votes in both chambers.

Days earlier, Sacramento Superior Court Judge Lauri Damrell dismissed the tribal coalition's SB 549 lawsuit against more than 90 card room and third-party proposition player defendants. Damrell did not reach the underlying question of whether card room games are house-banked. She held instead that SB 549 itself is preempted by the federal Indian Gaming Regulatory Act, reasoning that IGRA is comprehensive and leaves states no role outside the compacting process. The tribes filed notice of appeal, with briefing running into 2026.

November 2025: Federal Court Denies Injunction Against Kalshi

Three California tribes, the Blue Lake Rancheria, the Chicken Ranch Rancheria of Me-Wuk Indians and the Picayune Rancheria of the Chukchansi Indians, had sued Kalshi and its distribution partner Robinhood in July 2025, arguing that sports event contracts accessible to users physically located on reservations constitute unauthorized Class III gaming under IGRA.

U.S. District Judge Jacqueline Scott Corley denied the preliminary injunction in November. She found that secretarial procedures function as compacts under IGRA, a point favorable to the tribes, but concluded that the relevant provisions address internet games offered by tribes and say nothing about outside companies. She then held that the Unlawful Internet Gambling Enforcement Act governed the transactions, and that its definition of a bet or wager excludes transactions conducted on an entity registered under the Commodity Exchange Act, placing Kalshi within the exclusion.

January 2026: AB 831 Takes Effect

Dual-currency sweepstakes platforms exited California ahead of the Jan. 1 effective date. Sweepstakes sportsbook products, including Fliff, are no longer available to California players.

March 2026: Executive Order and Prediction Market Bills

Newsom issued an executive order barring gubernatorial appointees from using nonpublic information to trade on prediction market platforms. California lawmakers joined counterparts in Kentucky and Minnesota in introducing bills to regulate or restrict prediction markets, with sports-linked contracts the primary target.

July 2026: Ninth Circuit Argument and the 2028 Confirmation

The U.S. Court of Appeals for the Ninth Circuit heard argument on the tribes' appeal in the Kalshi case in July 2026, under case number 25-7504. Twenty-seven states and the District of Columbia filed an amicus brief supporting the tribes. A ruling is pending. In May, the Ninth Circuit had denied a tribal motion to reassign the appeal to the panel hearing a separate prediction markets case, citing significant differences between the two.

At the National Council of Legislators from Gaming States Summer Meeting in San Diego, CNIGA Chairman James Siva confirmed that tribes remain focused on 2028 for a tribally led online sports betting initiative. Siva was joined by CNIGA Vice Chair Steve Stallings, Cahuilla Band of Indians Chair Erica Schenk and Yuhaaviatam of San Manuel Nation Vice Chair Johnny Hernandez Jr.

Why California Still Has Not Legalized Sports Betting

California is not stalled because of moral opposition or legislative inattention. It is stalled because several well-funded groups with competing interests each hold enough political leverage to block an outcome they dislike, and none has been able to assemble a coalition broad enough to win.

The Tribal Coalition

California has 109 federally recognized tribes. Roughly 73 of them do not operate gaming facilities, and revenue-sharing arrangements distribute gaming proceeds to non-gaming tribes, which means any expansion has to satisfy far more governments than just the large casino operators.

Tribal governments hold Class III exclusivity and the political organization to defend it. They defeated a campaign funded by the largest sportsbook companies in the country in 2022. Siva has framed the current work explicitly around equity among tribes, stating that the goal is to ensure no tribe is left behind as gaming expands. Building that internal consensus before going to voters is the stated reason for the long timeline.

The Card Rooms

California's card rooms represent the most entrenched conflict. Tribes contend that the player-banked games card rooms spread, using third-party proposition players as the bank, violate tribal exclusivity under Proposition 1A. Card rooms maintain they are in full compliance.

The stakes extend well beyond the industry. Some municipalities derive a substantial share of their general fund revenue from card room taxes. San Jose officials have said the city receives roughly $30 million a year from card rooms, equivalent to funding for about 150 police officers. That local dependence gives card rooms legislative allies that tribes cannot easily overcome, and the unresolved SB 549 appeal keeps the conflict live.

Horse Racing Tracks

California's racetracks were included in Proposition 26 and would likely be included in any retail framework. The industry has contracted, and the tracks are not a driving force, but they remain a stakeholder with a claim on any expansion.

Commercial Sportsbook Operators

DraftKings, FanDuel and BetMGM spent heavily on Proposition 27 and lost decisively. Since 2025 they have pursued a different approach, pitching revenue-sharing partnership structures that leave tribes in control rather than seeking direct market access. Whether that is enough to earn tribal support for a 2028 measure is the open question.

Prediction Markets as a New Pressure

The most significant change since 2022 is that a substitute product arrived without waiting for a vote. Federally regulated prediction markets now offer sports event contracts to Californians, and tribal leaders describe them as a direct threat to both revenue and sovereignty, competing with regulated gaming while operating outside the same framework and, in their view, without contributing local employment or tax revenue.

CNIGA has said it will commission a study to quantify revenue losses attributable to these platforms. The presence of a functioning substitute cuts both ways. It reduces the urgency for consumers, and it increases the urgency for tribes.

Voter Sentiment

Polling has improved since 2022. An August 2025 poll found roughly 60 percent of California voters open to legalizing sports betting. That is a meaningful shift from the 2022 result, though the 2022 vote was shaped as much by voter confusion between two competing measures and by an unpopular advertising campaign as by opposition to sports betting itself.

When Will Sports Betting Be Legal in California?

The earliest realistic date for a vote is November 2028. The earliest realistic date for a live regulated market is 2029 or later.

Why 2026 Was Never Happening

CNIGA ruled out a 2026 measure in January 2025, and no initiative was filed or circulated for signatures in time to qualify. Nothing appears on the November 2026 ballot.

The 2028 Tribal Initiative

Siva has confirmed on multiple occasions in 2026 that tribes are preparing a tribally led initiative covering both in-person and online sports betting for the 2028 ballot. The framework has not been released. Tribes have been polling voters, including in June 2026, to shape the campaign, and the stated approach is to build consensus among all 109 tribes and educate voters before circulating anything, rather than repeating the 2022 pattern of competing measures.

What Has to Happen First

A measure has to be drafted and filed with the attorney general's office for title and summary. Signatures equal to 8 percent of votes cast in the last gubernatorial election must be gathered and verified by county elections officials, a process that takes months and typically requires collecting well above the minimum. The measure has to be certified for the ballot ahead of the statutory deadline. Then it has to win a majority of votes.

What Happens After a Yes Vote

Passage would not produce a market immediately. Tribal-state compacts would need to be renegotiated and ratified, a regulator would need to be designated and staffed, regulations would need to be drafted and adopted, operators and vendors would need to be licensed and platforms would need to be certified. Comparable states have taken 12 to 24 months from authorization to launch, and California's compacting requirement makes it more complex than most.

What a Legal California Market Would Look Like

Any framework emerging from a tribally led initiative would almost certainly place tribes in control of licensing, with commercial operators participating as platform providers or partners rather than as direct licensees. In-person registration requirements, tribal server siting and revenue-sharing provisions covering non-gaming tribes are all plausible components based on prior proposals and public statements.

On size, California would immediately become the largest sports betting market in the country by population. Comparable per-capita handle in mature states suggests annual handle well into the tens of billions of dollars, though tax structure, product restrictions and the extent of the prediction market substitution would all affect the actual figure.

Land-Based Sports Betting in California

There is no land-based sports betting in California. Not at tribal casinos, not at racetracks, not at card rooms, not anywhere.

This is often misunderstood, because California has a large tribal gaming industry and a long-established horse racing industry. Neither is authorized to take a sports wager. Tribal casinos operate under compacts that cover Class III gaming as defined at the time those compacts were negotiated, and sports betting is not included. Adding it would require both voter approval of a constitutional amendment and renegotiated compacts. Racetracks are licensed for pari-mutuel wagering on racing only. Card rooms are limited to player-banked card games and are prohibited from offering banked games at all, let alone sports betting.

Proposition 26 would have changed this by authorizing retail sportsbooks at tribal casinos and at licensed racetracks. It failed by more than 2 to 1 in 2022. If a 2028 measure passes and includes a retail component, tribal casino properties would be the venues where sportsbooks are built, and the buildout would follow compact renegotiation.

The nearest legal retail sportsbooks to California are in Nevada, Arizona and Oregon. Bettors sometimes travel to place wagers, and a bet placed legally in another state is a legal transaction in that state. Mobile betting accounts opened in those states will not function inside California, because geolocation technology blocks wagering outside licensed jurisdictions. Attempting to defeat geolocation is a violation of those operators' terms and grounds for account closure and forfeiture.

Legal Sports Wagering Alternatives in California

Prediction Markets

Prediction markets are exchanges regulated by the Commodity Futures Trading Commission where users trade contracts tied to the outcome of future events, including sporting events. A contract settles at $1 if the outcome occurs and at $0 if it does not, and the price between those points reflects the market's implied probability.

The mechanical difference from a sportsbook matters. A sportsbook is the counterparty to the bet and sets the price. An exchange matches buyers and sellers and takes a fee, and positions can generally be sold before the event resolves. Pricing is driven by order flow rather than by a book managing its own risk.

Kalshi is a CFTC-designated contract market and is the most widely used platform in California. Polymarket operates a U.S. product, and access is also available through brokers and partners including Robinhood, Crypto.com, FanDuel Predicts and DraftKings Predictions. Contracts cover major league championships, individual games and a range of non-sports categories including economics, politics and entertainment.

The legal position is contested and unresolved. Kalshi's argument is that event contracts are financial products under the Commodity Exchange Act and that federal regulation preempts state gambling law. That argument prevailed at the district court level in California in November 2025 and is now before the Ninth Circuit. It has not prevailed everywhere. A federal judge in the Southern District of New York ruled in 2026 that New York gambling law is not preempted by the Commodity Exchange Act, creating a split with a Third Circuit decision in New Jersey and increasing the likelihood of Supreme Court review.

Californians should understand that they are using a product whose legality is being actively decided. Gains are generally reported on Form 1099-B and treated under capital gains rules rather than as gambling income, which is a meaningful difference from a sportsbook, but tax treatment should be confirmed with a professional.

Daily Fantasy Sports

Paid daily fantasy sports contests are offered in California and have been for more than a decade. California has never passed a law authorizing them, and as of July 3, 2025, the state's chief legal officer has formally concluded that they are illegal.

Bonta's opinion concluded that participants in both pick'em and draft-style contests place bets on sporting events in violation of Section 337a. Because an attorney general opinion is advisory rather than binding, operators responded differently. DraftKings said it respectfully disagreed and continued operating. FanDuel said it was reviewing the opinion and told customers to continue playing normally. Underdog withdrew its standard pick'em product from California in July 2025 and replaced it with a peer-to-peer format in which entries are matched against other users rather than against a posted line. PrizePicks, Sleeper, Betr Picks, ParlayPlay and DraftKings Pick6 have continued to accept California entries.

The distinction operators draw is between contests where the user competes against the house on a posted statistical line, which most closely resembles a player prop, and contests where users compete against each other. Bonta drew no such distinction. Bettors should treat the category as legally disputed rather than settled, and understand that operator confidence is not a legal determination.

Horse Racing

Pari-mutuel wagering on horse racing is the only form of sports wagering in California that is unambiguously legal and state-licensed. It has been legal since 1933 and is overseen by the California Horse Racing Board. The minimum age is 18.

In pari-mutuel wagering, all bets on a race go into a pool, the track takes a percentage and the remainder is distributed among winning tickets. Odds reflect how the pool is distributed rather than a line set by a bookmaker, and final odds are not known until wagering closes.

Live racing continues at Santa Anita Park in Arcadia, Del Mar near San Diego and Los Alamitos in Orange County, along with seasonal fair meets in Northern California and harness racing at Cal Expo. Golden Gate Fields in Berkeley closed in 2024, a significant contraction for Northern California racing. Santa Anita regularly hosts the Breeders' Cup and runs the Santa Anita Derby and Santa Anita Handicap. Del Mar's summer meet is among the best attended in the country.

California permits advance deposit wagering, meaning residents can fund an account and bet on racing online from anywhere in the state through licensed operators including TwinSpires, FanDuel Racing and 1/ST BET. These are regulated, licensed businesses, and they are categorically different from offshore sportsbooks. Off-track betting facilities across the state accept wagers on California races and on tracks nationwide and internationally.

What Is No Longer Available

Sweepstakes sportsbooks, which used a dual-currency model to offer wagering-style play for redeemable prizes, are banned as of Jan. 1, 2026, under AB 831. Fliff, McLuck, Pulsz, WOW Vegas and other major platforms exited California before the deadline. Bettors should not use any dual-currency sweepstakes product from within California, and publishers should be aware that the statute reaches media affiliates who knowingly promote them.

California Teams to Bet On

No state has more to follow. California is home to 19 franchises across the five major professional leagues, plus the largest concentration of Division I college programs in the country.

NFL

The Los Angeles Rams and Los Angeles Chargers share SoFi Stadium in Inglewood, and the San Francisco 49ers play at Levi's Stadium in Santa Clara. Levi's Stadium hosted Super Bowl LX in February 2026.

The NFL drives more betting handle than any other sport in the United States, and Super Bowl Sunday is consistently the largest single-day handle of the year in every regulated market. A large population of Las Vegas Raiders fans also remains in Northern California following the franchise's relocation from Oakland.

NBA

The Los Angeles Lakers play at Crypto.com Arena, the Los Angeles Clippers moved into the Intuit Dome in Inglewood in 2024, the Golden State Warriors play at Chase Center in San Francisco and the Sacramento Kings play at Golden 1 Center. The Lakers and Warriors are among the most heavily bet franchises in the league nationally, both in game markets and in championship futures.

WNBA

The Los Angeles Sparks are one of the league's original franchises. The Golden State Valkyries began play in 2025 at Chase Center as the league's first expansion team in more than a decade. WNBA betting volume has grown sharply, and market depth has expanded accordingly.

MLB

California has more MLB teams than any other state. The Los Angeles Dodgers at Dodger Stadium, the San Francisco Giants at Oracle Park, the San Diego Padres at Petco Park and the Los Angeles Angels at Angel Stadium in Anaheim all play in the state. The Athletics left Oakland after the 2024 season and are playing at Sutter Health Park in West Sacramento while a permanent Las Vegas ballpark is built.

Baseball's daily schedule and long season make it the sport where line shopping and disciplined bankroll management matter most, and the Dodgers in particular are among the most bet teams in the sport.

NHL

The Anaheim Ducks play at Honda Center, the Los Angeles Kings at Crypto.com Arena and the San Jose Sharks at SAP Center. The state supports three franchises despite its climate, and the Kings and Ducks have combined for multiple Stanley Cup titles since 2007.

MLS and NWSL

Los Angeles FC and the LA Galaxy both play in the Los Angeles market, the San Jose Earthquakes are one of the league's original clubs and San Diego FC began play in 2025. On the NWSL side, Angel City FC plays in Los Angeles, Bay FC in the Bay Area and the San Diego Wave in San Diego. Soccer betting markets are deep at most books, with match result, both teams to score, corners, cards and player markets widely available.

College Football and Basketball

California has more NCAA Division I programs than any other state. USC and UCLA now compete in the Big Ten, while Cal and Stanford moved to the ACC, both realignments taking effect in 2024. San Diego State, Fresno State and San Jose State compete in the Mountain West and Pac-12 successor structures. Deep basketball traditions run through UCLA, USC, Stanford, Saint Mary's, Santa Clara, Loyola Marymount, Pepperdine, San Diego State and UC Santa Barbara.

Whether California college teams could be bet on under a future framework is an open question. Proposition 26 would have prohibited wagering on California college teams during league play, and several states with legal betting restrict or ban in-state college wagering and college player props. Any 2028 measure may contain similar limits.

Golf, Combat Sports and Motorsports

California hosts PGA Tour events at Torrey Pines, Pebble Beach and Riviera Country Club, all of which draw significant futures and matchup betting. The UFC stages cards in Los Angeles, Anaheim, Sacramento and San Diego, and California has a long boxing history centered on venues throughout Southern California.

Major Events in California

SoFi Stadium and Levi's Stadium both hosted matches during the 2026 FIFA World Cup. Los Angeles will host the Summer Olympics in 2028, the same year tribes are targeting for a sports betting vote. The Rose Bowl in Pasadena continues to host one of college football's marquee games each January. Santa Anita remains a regular Breeders' Cup site.

Taxes on Sports Betting Winnings

Gambling winnings are taxable income under federal law regardless of where the bet was placed and regardless of whether the operator was licensed. That includes winnings from offshore sportsbooks. Offshore books do not issue W-2G forms and do not report to the Internal Revenue Service, which does not remove the obligation to report.

California taxes gambling winnings as ordinary income at rates that reach 13.3 percent at the top bracket. California State Lottery prizes are exempt from state income tax, but no similar exemption applies to sports wagering. Gambling losses may be deducted only against gambling winnings and only by taxpayers who itemize.

Federal treatment of gambling loss deductions changed for tax year 2026, limiting the deductible portion of losses. Anyone with meaningful volume should work with a tax professional rather than relying on prior-year assumptions.

Prediction market gains are treated differently. Because the platforms are CFTC-regulated exchanges, profits are generally reported on Form 1099-B and taxed under capital gains rules rather than as gambling income. That can be advantageous, but the treatment should be confirmed for an individual situation.

Responsible Gambling in California

The absence of a regulated market in California removes the consumer protections that regulated markets require. There are no mandated deposit limits, no state self-exclusion program covering sportsbooks and no operator obligation to intervene when a customer shows signs of harm. That makes self-management more important here than in a regulated state, not less.

Warning Signs

Behaviors that warrant attention include betting more than intended or more than can be afforded to lose, chasing losses with larger wagers, borrowing money to bet, hiding betting activity from family, betting to relieve stress or low mood, restlessness or irritability when attempting to cut back, and betting interfering with work, sleep or relationships.

Where to Get Help in California

The California Office of Problem Gambling, part of the state Department of Public Health, administers CalGETS, the California Gambling Education and Treatment Services program. CalGETS provides free, confidential treatment to California residents and their family members, including counseling and support services.

The California Problem Gambling Helpline is available 24 hours a day at 1-800-GAMBLER. Support is also available by text and chat. The National Council on Problem Gambling operates a national helpline at the same number and maintains resources for family members as well as for gamblers.

Gamblers Anonymous holds meetings throughout California, and Gam-Anon provides support for family and friends.

Practical Controls

Set a monthly amount that can be lost without consequence and treat it as the ceiling. Do not deposit beyond it. Keep gambling funds in a separate account from bills and savings. Do not bet with borrowed money or credit. Track every wager, because the perception of results and the actual results diverge quickly. Take scheduled breaks, particularly after a large win or a large loss. If tools such as deposit limits or session limits are available on a platform, use them.

California Sports Betting FAQ

Is sports betting legal in California?

No. There is no legal online or retail sports betting in California. Voters rejected Propositions 26 and 27 in November 2022, and no measure has qualified for a ballot since.

When will sports betting be legal in California?

The earliest realistic vote is November 2028, which is the target tribal leaders have publicly confirmed. A live market would follow later, after compact renegotiation and regulatory implementation.

Can I get in trouble for betting online in California?

Penal Code Section 337a is written broadly enough that its language reaches placing a bet as well as accepting one, and legal commentary disagrees about whether it applies to individual online bettors. Enforcement has historically targeted operators rather than customers, and there is no record of California prosecuting an individual for placing an online sports bet. This is not legal advice, and anyone concerned should consult a California attorney.

Will DraftKings and FanDuel launch sportsbooks in California?

Not without a constitutional amendment approved by voters. Both companies funded Proposition 27, which failed with roughly 82 percent voting no. Since 2025 they have pursued partnership models with tribal governments instead of seeking direct market access.

Are offshore sportsbooks safe?

They are unregulated. Several have long operating histories and pay customers reliably, but there is no California or U.S. regulator to appeal to if an account is closed, a wager is voided or a withdrawal is refused, and player funds are not protected.

Is Kalshi legal in California?

Kalshi is a CFTC-designated contract market and continues to operate in California. Three California tribes have challenged its sports event contracts, a federal judge denied their injunction in November 2025 and the Ninth Circuit heard the appeal in July 2026. A ruling is pending.

Is DraftKings daily fantasy legal in California?

Attorney General Bonta concluded on July 3, 2025, that paid daily fantasy contests violate Section 337a. The opinion is advisory rather than binding, and DraftKings and most other operators have continued to accept California entries.

Are sweepstakes sportsbooks still available in California?

No. AB 831 took effect Jan. 1, 2026, and dual-currency sweepstakes platforms exited the state.

Can I use a Nevada betting app from California?

No. Regulated sportsbook apps use geolocation to confirm a bettor is inside a licensed jurisdiction and will not accept a wager from California. Attempting to circumvent geolocation violates operator terms and can result in account closure and forfeited funds.

What is the legal gambling age in California?

Eighteen for horse racing and the state lottery, 18 or 21 at tribal casinos depending on the property, and 18 for prediction markets. Both 2022 sports betting measures would have set the minimum at 21.

Who would regulate sports betting in California?

Both 2022 measures designated the Bureau of Gambling Control within the California Department of Justice. The California Gambling Control Commission would likely have a role as well.
