Best California Sports Betting Sites 2025

Updated May 2025 — Expert Verified

California remains the largest US state without legal sports betting. The twin defeats of Propositions 26 and 27 in November 2022 — after record-shattering campaign spending — left the Golden State's massive sports fan base without a single regulated sportsbook. No new legislation has advanced, and the political dynamics that torpedoed both measures remain firmly in place. For CA residents who want to place real-money wagers on sports, offshore and international sportsbook platforms are the primary option. These platforms are not licensed in any US state, but they accept California players and offer pre-match betting, live wagering, and competitive odds across major leagues. This guide reviews the top offshore sportsbooks that serve California players, explains the current legal landscape, and addresses what the future may hold.

Detailed Reviews — Offshore Sportsbooks for California Players

#1 Tenobet — "The Complete Sports and Casino Experience"

Welcome Offer: 400% up to $5,000 New players only. 25x wagering. T&Cs apply.

Visit Tenobet | Rating: 4.9/5

Payment Methods: Visa, Mastercard, Bitcoin, Ethereum, bank transfer, e-wallets

Pros:

• Full sportsbook with pre-match and live betting across major leagues
• 3,500+ casino games alongside the sportsbook
• 400% match with 25x wagering — strong value
• Dollar-denominated — no currency conversion for US players
• Clean interface that transitions smoothly between sports and casino

Cons:

• Some niche sports markets have thinner lines than dedicated sportsbooks
• Newer platform still building a long-term track record

Tenobet earns the top sportsbook ranking for California players because it delivers the strongest combination of sports betting and casino gaming in a single platform. The sportsbook covers every major US league along with international soccer, tennis, MMA, and esports. Both pre-match and live betting are available, with competitive odds that hold up against dedicated offshore sportsbooks.

What distinguishes Tenobet from competitors that bolt a sportsbook onto a casino is the integration quality. Switching between placing a sports bet and spinning a slot takes one tap. Your account balance is unified, and the interface maintains its clean, modern feel across both sections. For CA sports fans who also enjoy casino games, Tenobet eliminates the need for separate platforms.

The 400% welcome match up to $5,000 is the most generous dollar-denominated sportsbook bonus on this list. At 25x wagering, the terms are competitive. Live betting deserves special mention — odds update in real time, markets stay open deep into games, and the interface makes placing in-play wagers intuitive on mobile. During football season, the Sunday live betting experience rivals what players in regulated states access through licensed operators.

Players must be 18+ to participate. Terms and conditions apply to all offers.

#2 Donbet — "Deep Markets with a Distinctive Style"

Welcome Offer: 150% up to £750 + 50 Free Spins New players only. T&Cs apply.

Visit Donbet | Rating: 4.8/5

Payment Methods: Visa, Mastercard, Bitcoin, Ethereum, Skrill, Neteller, bank transfer

Pros:

• Deepest sportsbook market coverage on this list
• 4,000+ casino games alongside the sportsbook
• Mafia-themed design gives the platform distinctive character
• Pre-match, live, and outright markets across major sports

Cons:

• GBP-denominated bonus requires currency conversion for US players
• 150% match is lower than Tenobet's 400%

Donbet fields the most comprehensive sportsbook among the platforms we reviewed for California players. Beyond standard US league coverage, Donbet offers extensive soccer markets spanning European leagues and international fixtures, along with tennis, boxing, and cricket. The depth of props and alternative lines on major US sports is above average for an offshore operator, which matters for bettors who want more than moneyline and spread options. The casino side adds 4,000+ games, and the 50 Free Spins provide a taste of the casino without additional deposits. Donbet is the strongest pick for CA sports bettors who value market depth and variety above all else.

Players must be 18+ to participate. Terms and conditions apply to all offers.

#3 Goldenbet — "Where the Odds Work in Your Favor"

Welcome Offer: Casino + Sports Welcome Bonus New players only. T&Cs apply.

Visit Goldenbet | Rating: 4.7/5

Payment Methods: Visa, Mastercard, Bitcoin, Ethereum, bank transfer, e-wallets

Pros:

• Consistently competitive odds across major US sports
• Strong live betting platform with real-time updates
• Combined sportsbook and casino welcome offer
• Clean interface with fast page loading

Cons:

• Welcome bonus details are less transparent than competitors
• Fewer unique features compared to more specialized platforms

Goldenbet's core value proposition is straightforward: better odds. While most offshore sportsbooks offer comparable markets, Goldenbet consistently prices its lines more favorably across NFL, NBA, and major soccer leagues. Over time, those differences compound into meaningful value for regular bettors.

The live betting platform is well-executed — odds update smoothly, markets remain available deep into contests, and the bet slip process is fast. The combined casino and sportsbook welcome bonus lets new players allocate across both verticals, which is useful for the CA player who wants to bet on the Lakers and play blackjack in the same session. Goldenbet focuses on doing the fundamentals well — pricing, execution speed, and market availability — and delivers on those priorities.

Players must be 18+ to participate. Terms and conditions apply to all offers.

#4 Freshbet — "90,000+ Live Events for the In-Play Bettor"

Welcome Offer: Up to €1,500 New players only. T&Cs apply.

Visit Freshbet | Rating: 4.7/5

Payment Methods: Visa, Mastercard, Bitcoin, Ethereum, Litecoin, Skrill, Neteller, bank transfer

Pros:

• 90,000+ live events — deepest live betting catalog available
• 3,000+ casino games alongside the sportsbook
• Covers obscure leagues and lower-tier competitions
• Multiple crypto and fiat payment methods

Cons:

• Euro-denominated bonus requires currency conversion
• Volume of live events can make navigation challenging

Freshbet distinguishes itself through one staggering number: more than 90,000 live sports events for in-play betting annually. That includes major US sports, international soccer lower divisions, esports tournaments, and niche competitions that most offshore sportsbooks do not touch. When US sports are in their offseason, you can bet live on European basketball, South American soccer, or Asian table tennis. For the California bettor who wants action at any hour, Freshbet eliminates seasonal dead zones.

The casino side offers over 3,000 games, making Freshbet a viable dual-purpose platform. The welcome bonus reaches €1,500 when claimed across eligible deposits, providing meaningful starting capital. The challenge is information density — with so many live events running simultaneously, the interface can feel crowded. Experienced bettors who know their sport will find what they need quickly.

Players must be 18+ to participate. Terms and conditions apply to all offers.

#5 MyStake — "Sports Betting Plus Exclusive Casino Mini-Games"

Welcome Offer: 150% up to €1,000 New players only. T&Cs apply.

Pros:

• Full sportsbook with live betting across major sports
• 7,000+ casino games with exclusive mini-games
• VIP program rewards both sportsbook and casino activity
• Strong cryptocurrency support

Cons:

• 150% match is modest compared to Tenobet's 400%
• Platform can feel busy given the content volume

MyStake pairs a solid sportsbook with something no other platform offers: exclusive mini-games. After placing your sports bets, jump into Chicken, Dino, or Icefield for fast-paced action. The sportsbook covers all major US leagues plus international soccer, tennis, and esports. With 7,000+ casino games and a VIP program spanning both verticals, MyStake is ideal for the California player who wants variety under one roof.

Players must be 18+ to participate. Terms and conditions apply to all offers.

Pros:

• 70+ game providers — widest provider network reviewed

Cons:

Pros:

• 450% welcome bonus among the most generous available
• 4,000+ casino games with strong variety
• Fast payout processing

Cons:

• No dedicated sportsbook — casino-focused platform

Lucki Casino appears on this list as a top casino companion for California sports bettors. While it does not operate a dedicated sportsbook, the 450% welcome bonus and 4,000+ game library make it a compelling secondary platform for CA players who already have a sportsbook account at Tenobet or Donbet.

Players must be 18+ to participate. Terms and conditions apply to all offers.

Pros:

What Is Offshore Sports Betting, and Why Do California Residents Use It?

Offshore sportsbooks are real-money sports wagering platforms operating from jurisdictions outside the United States. They hold international licenses and accept players from US states where regulated sports betting is unavailable. California, as the nation's largest state and one of the biggest sports markets in the world, generates enormous demand for these platforms.

That demand exists because California has no legal path to sports betting. The decisive failure of both Propositions 26 and 27 in November 2022 shut down the most serious legalization efforts in the state's history. Proposition 26, backed by tribal gaming interests, would have authorized in-person sports betting at tribal casinos and racetracks. Proposition 27, supported by commercial operators, proposed statewide online betting through operator-tribe partnerships. The tribal coalition opposed Prop 27 aggressively, and voters rejected both — Prop 26 with about 70% voting no, Prop 27 with roughly 83% opposed. Combined spending exceeded $400 million.

The result is a vacuum. California's sports fan base — home to NFL, NBA, MLB, NHL, and MLS franchises across Los Angeles, San Francisco, San Diego, and Sacramento — has no regulated outlet for sports wagering. Offshore platforms fill that gap with pre-match betting, live in-play wagering, futures, props, and parlays across all major sports and many niche markets. These platforms are not subject to US regulation, meaning players do not receive the consumer protections available in states like New Jersey, Colorado, or Arizona. But they provide the only real-money sports betting option for California's millions of fans, and the platforms reviewed in this guide have demonstrated consistent payout processing and fair market operations.

Offshore vs. Regulated US Sportsbooks

Critical Warning: Offshore sportsbooks are not regulated by any US authority. Deposits are not protected by state gaming regulations, and disputes cannot be resolved through US channels. Never deposit more than you can afford to lose.

How to Choose the Right Offshore Sportsbook in California

2. Assess Odds Pricing — Small differences compound over time. Goldenbet offers the tightest lines.
3. Evaluate Cross-Platform Needs — Want sportsbook + casino? Tenobet, MyStake, and Rolletto are strongest. Dedicated sports? Donbet and Goldenbet.
4. Test Withdrawals Early — Small deposit, place bets, request a withdrawal before committing more.

6. Read Current Bonus Terms — Offers change. Verify wagering requirements, minimum odds, and expiration before depositing.

Is Sports Betting Legal in California?

Traditional sports betting is not legal in California. You cannot place a wager through any licensed operator — online or in person — anywhere in the state.

Proposition 26: In-Person Sports Betting

Proposition 26 would have authorized in-person sports betting at tribal casinos and four licensed horse racetracks. Despite tribal backing, it failed with approximately 70% of voters saying no.

Proposition 27: Online Sports Betting

Proposition 27 proposed statewide online sports betting through commercial-tribal partnerships. Nearly every tribal nation campaigned against it, and voters rejected it by roughly 83% to 17%.

Combined Campaign Spending

The two campaigns combined for more than $400 million — the most expensive ballot fight in American history at the time.

Current Status and Future Outlook

As of May 2025, no sports betting legislation has advanced. No ballot measures have qualified. The earliest realistic window for a new attempt is 2028, though even that is speculative. Tribal influence remains strong, commercial operators lack leverage, and voter appetite for expanded gambling appears limited.

Legal Summary: Sports betting is illegal in California. Props 26 and 27 both failed in November 2022. Offshore sportsbooks accept CA players but operate outside US oversight. No legislation is currently pending.

---

Responsible Gambling in California

Offshore sports betting involves real money and real financial risk. Set a bankroll before you begin, never wager money you cannot afford to lose, and avoid increasing stakes to chase losses. Take breaks during extended sessions.
