California Sports Betting Explained: Best Offshore Sites to Bet Online in 2025

Top Mobile Sportsbooks for California Bettors in 2025

Californians love to bet on the go, which makes mobile performance a crucial part of the online sports betting California experience. While most offshore sportsbooks don’t offer dedicated mobile apps, several platforms stand out with smooth, reliable mobile browser versions.

Everygame delivers the strongest mobile interface overall, offering an app-like design on both iOS and Android. It’s fast, intuitive, and ideal for live betting—even when your connection isn’t perfect.

If you prioritize real-time stats and in-play betting, Bovada is another top option. Its browser-based mobile platform is quick, responsive, and well-suited for betting on popular California teams like the Lakers and 49ers from anywhere in the state.

How We Chose the Best California Online Sportsbooks

Our team reviewed dozens of offshore sportsbooks to determine the best California sports betting sites for 2025. To give bettors the most accurate insights, we evaluated each platform using key criteria such as market depth, odds competitiveness, bonus value, payment flexibility, crypto transaction speed, site security, and overall user experience—both on desktop and mobile. Since many players rely on sports betting apps California fans can access through their mobile browsers, mobile performance was a major focus.

Every platform was tested hands-on across multiple devices to assess real-time betting flow, live wagering features, interface speed, and withdrawal processing. We also considered how well each sportsbook supports sports betting in California, including coverage of local teams, in-play betting tools, and the variety offered by leading online sportsbooks. Because many residents explore California online sports betting through offshore platforms, consistency and trustworthiness played an important role in our scoring.

To ensure complete accuracy, our team verified all promotions, payout structures, and licensing details as of mid-2025. Only sportsbooks with proven reputations, strong player feedback, active licenses, and robust features made our final list of top sports betting sites California bettors can rely on. These platforms remain the most trusted options for sports betting California players until regulated alternatives launch statewide.

Is Online Sports Betting Legal in California?

California sports betting is still not legalized as of mid-2025. Residents cannot access state-regulated sportsbooks because both Proposition 26 (retail tribal betting) and Proposition 27 (online and mobile sports betting) were rejected by voters in November 2022—Prop 26 by nearly two-thirds and Prop 27 by more than 80%. As a result, there are currently no legal California sports betting apps or state-licensed online sportsbooks available.

However, Californians can legally use reputable offshore sportsbooks that operate under international licenses. These platforms accept California players without violating state law. Many bettors also turn to daily fantasy sports (DFS) and social betting apps, which remain legal alternatives within the state.

This information is provided for educational purposes only and should not be taken as legal advice. At present, Californians rely on licensed offshore sportsbooks and DFS platforms to participate in sports betting in California until legislation changes.

Key takeaway: Sports betting isn’t regulated in California yet, but offshore sportsbooks and DFS platforms offer legal ways to wager. With tribal and voter interest slowly shifting, a new ballot initiative could bring legalization as early as 2026.

Key Betting Regulations & Developments

• 2022 – Proposition 27 (Online Sports Betting): CA voters rejected Prop 27 by over 80%, which would have allowed mobile sports betting through partnerships with tribes. Its defeat effectively halted online legalization for now.
• 2022 – Proposition 26 (Retail Tribal Betting): Also defeated by nearly 67%—this proposition aimed to legalize in-person betting at tribal casinos and racetracks.
• 2023–2024 – Tribal Sports Betting Initiative (Filed): A tribe-led initiative was introduced to authorize exclusive tribal-controlled online and retail betting but is still under review, with no ballot yet.
• Early 2025 – DraftKings/FanDuel + Tribal Talks: Sports operators announced ongoing negotiations with tribal leaders to support a 2026 ballot initiative, emphasizing a tribal-led governance model.
• Market Commentary & Sponsorship Trends: In late 2024, industry analysts noted California remains one of two large “holdout” states, though operators continue sponsoring teams and events to build grassroots support.

Popular Sports for Online Betting in California

California’s sports culture is as massive as its population, making it a hotbed for online sports betting, even via offshore platforms. Here are the most popular sports that California bettors wager on regularly:

NFL (Football) – California is home to the San Francisco 49ers and Los Angeles Rams, two of the league’s most bet-on teams. College football also draws huge action, especially from USC and UCLA fans.

NBA (Basketball) – The Los Angeles Lakers and Golden State Warriors have massive fanbases and frequent playoff appearances, driving consistent betting interest across the state.

MLB (Baseball) – With iconic teams like the Dodgers, Giants, and Angels, baseball is a staple for daily and futures betting throughout the season.

NCAA (College Sports) – March Madness betting spikes every spring, especially with Pac-12 programs like UCLA and USC competing on the national stage.

Soccer – MLS franchises LAFC and LA Galaxy are popular, while international tournaments like the World Cup see surging California traffic.

NASCAR & Golf – From Sonoma Raceway to Pebble Beach, major events attract prop bets and loyal fan wagering all year.

Major California Sports Events You Can Bet On in 2025

California regularly hosts some of the most anticipated sporting events in the U.S., drawing significant betting attention, especially from local fans looking to wager on familiar ground.

Indian Wells Masters (Tennis) – Known as the BNP Paribas Open, this elite tennis tournament in Indian Wells is one of the biggest non-Grand Slam events and a favorite for futures and match betting.

LA Grand Prix (Formula 1) – With Formula 1 expanding in the U.S., the new Los Angeles Grand Prix is generating buzz among motorsports bettors seeking high-speed action and unique betting props.

Rose Bowl Game (College Football) – Held annually in Pasadena, the Rose Bowl is a college football tradition and a major draw for spread and over/under bets.

US Open (Golf) – Often hosted at courses like Pebble Beach, this PGA major draws heavy betting interest, especially on top-ranked golfers and tournament matchups.

Cricket World Cup / Local Cricket – With a growing South Asian community, international cricket events—especially the World Cup—attract niche but dedicated offshore betting traffic.

Sports Betting Landscape in California: Trends & Market Size

California sports betting remains one of the biggest untapped opportunities in the United States. With nearly 40 million residents, the Golden State represents a massive potential market for California online sports betting. Analysts from Eilers & Krejcik estimate that full legalization could generate more than $3 billion in annual revenue. A nationwide study also notes that offshore sportsbooks currently handle nearly twice the wagering volume of regulated U.S. platforms, highlighting how active sports betting California already is—despite the lack of state-regulated options.

Because voters rejected prior proposals, many residents still ask why is sports betting illegal in California, especially given the size of the market. Even so, betting activity remains strong through offshore sportsbooks, daily fantasy platforms, and even niche football betting sites, especially during high-profile events like the Super Bowl or March Madness. Offshore options also function as the de facto sports betting apps California players rely on until regulated platforms arrive.

Trends from 2024 show continued national growth, with legal wagering surpassing $130 billion. And even without state-regulated sportsbooks, California bettors remain highly engaged—using offshore platforms, DFS apps like Underdog Pick’Em, and searching for the best sports betting sites California or other trusted sports betting sites California to place their wagers safely.

Here’s a snapshot of California’s gambling market by segment:

As public interest climbs and legislative momentum builds, California may finally legalize sports betting—likely via a new ballot initiative in 2026–28.

How California Taxes Your Sports Betting and Gambling Winnings

All gambling winnings are fully taxable income on both your federal and California state tax returns. The IRS requires you to report all winnings—including offshore sportsbook payouts—on Form 1040 (“Other Income”) even if no Form W‑2G is issued. Federally, winnings over $5,000 are typically subject to 24% withholding; actual tax liability may vary depending on overall income. 

California treats non-lottery gambling winnings as ordinary income and taxes them at your regular state rate. Large wins may be automatically withheld by payers. You can deduct gambling losses only if you itemize deductions and only up to the amount of your winnings. Always consult a tax professional for personalized advice.

Where to Bet in Person: Retail Sports Betting in California

As of 2025, California has no state-regulated retail sportsbooks—meaning you can’t legally place in-person sports bets at any casino, racetrack, or stadium. While multiple California sports betting initiatives have failed, many residents still visit tribal casinos and licensed card rooms to gamble on slots, poker, and table games.

For horse racing, wagering is permitted at tracks like Santa Anita Park, Del Mar Racetrack, and through Off-Track Betting (OTB) facilities. However, until a new law passes or a future ballot measure succeeds, retail sports betting remains unavailable across the state.

The Road to Legal Sports Betting in California: What’s Next?

Most analysts agree that California sports betting is nearly certain to become legal eventually, though likely not until after another state ballot, possibly in 2026 at the earliest. Recent discussions in early 2025 have brought DraftKings, FanDuel, and tribal leaders to the table at the Indian Gaming Tradeshow, with industry bodies forming joint frameworks that could lead to a tribal-backed ballot initiative.

Public support remains cautious—polls in 2022 found only 34% of likely voters in favor of Prop 27, while recent surveys show support slowly climbing. At the same time, mobile gaming growth and increasing offshore activity suggest pent-up demand is building among California bettors.

Bottom line: The path is slow but promising. With tribal-commercial partnerships gaining momentum and growing public interest, a renewed push in 2026 is likely, making California sports betting one of the most anticipated regulatory stories of the decade.

What Other Forms of Gambling Are Legal in California?

While sports betting remains off-limits for now, California offers several other legal gambling options that are popular across the state. Here are the most common and accessible forms of gambling currently permitted:

• Tribal Casinos (Indian Gaming): California has over 65 licensed tribal casinos, including Pechanga, Yaamava’, and Thunder Valley. These casinos legally offer slot machines, blackjack, roulette, and other table games, regulated under tribal-state compacts.
• State Lottery: The California Lottery is fully legal and includes scratchers, draw games, and multi-state lotteries like Powerball and Mega Millions. Proceeds support public education.
• Card Rooms: Dozens of card rooms such as Commerce Casino and The Bicycle Hotel & Casino legally operate poker, Pai Gow, and other player-versus-player games. Online poker is not currently legal in California.
• Daily Fantasy Sports: DFS platforms like DraftKings and FanDuel are legal to use in CA. These are classified as games of skill, not gambling, under state interpretation.
• Horse Racing (Pari-Mutuel): Live and simulcast horse racing betting is legal at tracks like Santa Anita Park, as well as Off-Track Betting (OTB) locations throughout the state.
• Charitable Gaming / Poker Tournaments: Nonprofit organizations may run bingo games, raffles, and poker tournaments under regulated conditions, usually for fundraising purposes.

How California Sports Betting Compares to Other States

California remains one of the few major states without legalized sports betting, placing it behind most of its neighbors in the western U.S. and far behind national leaders.

Nevada legalized both retail and mobile sports betting in 2018 and remains a top destination for California bettors, especially those near the Las Vegas Strip and Reno. Many drive across the border just to place legal wagers.

Arizona launched mobile sports betting in 2021, followed by Oregon in 2022. Both states now have regulated apps, allowing full mobile access to local and out-of-state bettors.

Washington has extremely limited gambling laws, with no legal mobile or DFS options, while Utah bans all forms of gambling entirely due to constitutional prohibitions.

Meanwhile, larger states like New York and Ohio have embraced mobile betting, with New York generating over $1 billion in annual tax revenue from legalized sportsbooks.

Bottom line: California lags far behind—but with its size and demand, it has the potential to leap ahead quickly once laws are passed.

Gambling should always be a form of entertainment—not a financial strategy. If you choose to bet online from California, it’s essential to play responsibly. Set clear spending limits, avoid chasing losses, and never wager more than you can afford to lose.
