Best California Sportsbook Promos & Bonuses for September 2026
California sports betting still isn’t legal, and it won’t be on the ballot this year. Tribal leaders confirmed this summer that they’re targeting a 2028 sports betting measure instead of trying again in 2026, still wary after the costly defeat of Propositions 26 and 27 back in 2022. Meanwhile, the rise of prediction markets like Kalshi and Polymarket has added a new wrinkle to the conversation, giving Californians another way to trade on sports outcomes while a licensed sportsbook market remains years away.
Until real-money sports betting arrives, Californians can still sign up for DFS pick’em and social sportsbook promos. This page ranks and reviews the best available apps and tracks the latest on the future of California sportsbook promos.

Can you bet on sports in California?
California sports betting is illegal. At the moment, it is not possible to bet on sports legally in person or online in the state. To place wagers related to sports, those in the Golden State must register for a Daily Fantasy Sports site such as the ones listed above.
When will online sportsbooks come to California?
The future of sports betting in California is unclear. After voters denied two ballot options in 2022, no attempts to legalize sports betting have made any traction. Many experts now project that legal sports betting in California, if brought to voters, won’t happen before 2028.
California DFS pick’em and social sportsbooks
While no legal sports betting apps exist in California, daily fantasy sports and social sportsbooks are available. California has never formally legalized DFS or social sportsbooks, but it has not made them explicitly illegal. These platforms continue to operate in the state despite being unregulated, and some are now offering sportsbook promos and bonuses to new users. Below is a look at some of our favorites:
1. FanDuel Predicts
Sign Up & Unlock Your Offer at FanDuel Predicts

No promo code is required, and the bonus is non-withdrawable and subject to the promotion’s applicable terms and expiration period.
What is FanDuel Predicts?
FanDuel Predicts is FanDuel’s prediction-market platform, giving users the ability to trade contracts on real-world events ranging from sports and entertainment to financial markets, cryptocurrencies and economic indicators.

- Sports and entertainment: Trade on outcomes involving major sports and entertainment events, with availability varying by state.
- Financial markets: Make predictions on benchmarks such as the S&P 500 and Nasdaq-100, as well as commodities, cryptocurrencies and economic indicators.
- Yes or No contracts: Choose whether you think an event will happen, decide how much to trade and see the potential payout before placing your position.
- Cash out early: Depending on the market, users can sell their position before an event is resolved rather than waiting for the final outcome.
- Combination contracts: FanDuel Predicts has expanded its offering to include combination event contracts alongside its traditional markets.
2. Polymarket

Polymarket’s current U.S. promotion offers eligible new users a $50 Trading Bonus when they deposit $10, with the offer currently promoted using promo code . The promotion is available in most eligible U.S. states, although some states are excluded, and the bonus can be used to trade eligible prediction markets.
What is Polymarket?
Polymarket is a peer-to-peer prediction market where users buy and sell shares tied to the outcomes of real-world events. Markets cover a huge range of subjects, including sports, politics, elections, economics, finance, crypto, culture, technology and geopolitics, with share prices generally representing the market’s implied probability of an outcome.
- Huge variety of markets: Choose from thousands of markets covering sports, politics, finance, crypto, culture and breaking news.

The $20 bonus gives new users additional funds to explore ProphetX’s sports prediction markets after making their first trade. The current offer is listed as available in eligible U.S. states, subject to regulatory approval and the applicable promotional terms.
What is ProphetX?
ProphetX is a peer-to-peer sports prediction exchange where users trade event contracts based on the expected outcome of games and sporting events. Rather than simply accepting a fixed price, ProphetX gives traders access to market-based pricing and tools such as limit orders, while offering markets across sports including the NFL, NBA, MLB, NHL, soccer, golf and UFC.
- Sports-first platform: ProphetX focuses heavily on sports markets, making it particularly appealing to users who want prediction trading centered on games and competitions.
- Peer-to-peer exchange: Trades are matched between participants rather than against a traditional sportsbook.

- Parlay trading: ProphetX also supports multi-event combinations, giving users another way to build positions across multiple sporting events.

What is Underdog Fantasy?
There are two ways to play Underdog Fantasy contests:
- Best ball: This format is all about the draft. Complete a snake draft with your fellow participants, and then set your team aside until the contest wraps up. The app automatically selects your best available lineup each week for the duration of the contest. Plenty of options exist when it comes to buy-in amounts, contest lengths, and field sizes.
- Pick’em: This style of game has two types of contests. With higher/lower, you select one or the other for a range of lines that Underdog sets, similar to a player prop bet. With rivals, you choose between two players, selecting who you think will score more fantasy points.
Possible California sportsbook promos
Though it may be years before legal sports betting becomes available in California, we can make educated guesses about which sportsbooks might eventually launch in the Golden State and begin offering sportsbook promos.
1. FanDuel Sportsbook
The leader among sports betting apps nationwide, FanDuel Sportsbook is the most likely app to launch in California. The company has been at the forefront of the push to legalize sports betting in the state and has even hired executives with experience with California tribes, including former National Indian Gaming Commission chairman E. Sequoyah Simermeyer.
2. DraftKings Sportsbook
After FanDuel, DraftKings Sportsbook has probably been the second most active sportsbook in attempting to lobby for legal sports betting in California. DraftKings is also already live in almost every other state where online sports betting is legal.
3. Fanatics Sportsbook
One of the fastest-growing sportsbooks in the US, this retail giant is likely to be in the conversation with any new state launch. Fanatics Sportsbook has already been a prominent player in newly legal states such as North Carolina, Kentucky, and Vermont, and California would likely not be any different.
4. Caesars Sportsbook and BetMGM Sportsbook
Though a distant third and fourth in terms of market share in many states, Caesars Sportsbook and BetMGM Sportsbook are well-established brands that would certainly push to capitalize on the opportunity California presents.

California sportsbook promo FAQs
Any online sports betting site claiming to take bets in California operates illegally and outside US laws. We do not recommend using these offshore sportsbooks as they are unregulated and do not hold licenses anywhere in the country.
FanDuel Sportsbook is not available in California, as sports betting is not yet legal or available in the state.
Many of the above apps, the California State Lottery, and horse betting require users to be at least 18 years old. However, if sports betting becomes legal in the state, users will likely have to be 21 or older.
Some experts have predicted that legal sports betting will not be available in California until at least 2026. The earliest possible date would be 2025, but the current political climate suggests that is unlikely.
None, at the moment. DFS pick’em and social sportsbook apps are available, but no legal sports betting apps are live in the state.
Without laws permitting legal sports betting in the state, it is hard to say whether college sports betting will eventually be legal in California. Some states prohibit betting on in-state college teams, while others have no restrictions on college sports betting at all.
Until sports betting is legalized in California, we will not know the specifics of what you might be able to wager on. However, if sports betting does become legal in the state, bettors will likely be able to wager on all the state’s professional teams, such as the Los Angeles Lakers, Los Angeles Rams, Los Angeles Dodgers, San Francisco 49ers, and Golden State Warriors.
