California Sports Betting: Best Prediction Markets and DFS Options

No, as of October 30, 2026, sports betting in California is not legal, including online sports betting. That means Californians do not have access to the traditional online sportsbooks and sports betting sites available in states where sports betting is legal.

Why isn't sports betting legal in California?

The reason is simple. California voters rejected two California sports betting initiatives in November 2022 that would have legalized sports betting in the state. Proposition 26 would have legalized retail sports betting at tribal casinos and select horse racetracks, while Proposition 27 sought to authorize statewide online sports betting. 

As a result, California remains one of the largest states without legal retail or online sportsbooks. The status of California sports betting could eventually change. Tribal groups have expressed interest in pursuing a new sports betting ballot initiative, potentially as early as 2028. 

Are prediction markets legal in California? 

Yes, while sports betting remains out of reach, California residents can access the top prediction market apps such as Kalshi, Polymarket, and Novig, which are federally regulated by the Commodity Futures Trading Commission (CFTC) and legal to use in California. These trading platforms allow users to speculate on sports-related events and other real-world markets through event contract trading, a mechanism that closely resembles online betting. 

Daily fantasy sports (DFS) also remains a legal option for Californians looking to speculate on sports through a fantasy-game format.

What is the best sports betting app available in California?

Because traditional sportsbooks and online sports betting are illegal in California, residents can use federally regulated prediction market trading apps, such as Kalshi and Polymarket. These prediction market platforms are legal to use in California—along with certain daily fantasy sports platforms, such as DraftKings DFS—and let users speculate on sports outcomes and other real-world events much like top sports betting apps.

In California, prediction market users can now legally access these platforms and place trades on moneylines, spreads, game totals, and player props for all NFL games. California matchups to watch in Week 7 include Los Angeles Rams at Las Vegas Raiders and San Francisco 49ers at Atlanta Falcons. 

Read our prediction markets vs. sports betting guide to learn all the differences between the way prediction markets and online sportsbooks operate.

As sports betting is not legal in California, the state does not currently license or regulate sportsbooks.

While traditional sportsbooks aren't legal, prediction markets are available and currently legal to use in the Golden State. These prediction market sites operate under federal oversight rather than state sports betting laws. Platforms such as Kalshi and Polymarket are regulated by the CFTC, allowing users to trade event contracts in states where sports betting remains prohibited.

California residents should also remember that gambling winnings and prediction market profits are generally considered taxable income under both federal and California tax laws.

📅 2027: California tribal gaming interests could begin preparations for a proposed 2028 sports betting ballot initiative, although no statewide measure has been formally confirmed.

📅 2026: Sports betting remains illegal in California, with no legalization measure on the November ballot. In July, California tribal gaming leaders reaffirmed plans to target a 2028 ballot initiative for online sports betting, although no proposal has officially qualified.

📅 2025: California tribes, gaming stakeholders and sportsbook operators continue discussions about the future of legal sports betting, but no legislation or statewide ballot measure advances.

📅 2024: California moves further away from an immediate sports betting ballot campaign following the overwhelming defeat of the 2022 measures. Tribal leaders continue to emphasize that any future proposal will require broad tribal support.

📅 2022: California voters overwhelmingly reject both sports betting initiatives. Proposition 26, which would have permitted retail sports betting at tribal casinos and certain racetracks, received only about 33% support, while Proposition 27, which proposed statewide online sports betting, received roughly 18% support.

📅 2021: Competing tribal and commercial sports betting campaigns gather support and signatures for measures that ultimately qualify for California's 2022 general election ballot.

📅 May 2018: The U.S. Supreme Court overturns PASPA, allowing individual states to legalize and regulate sports betting and opening the door for California to consider its own legalization framework.

Since the top sports betting apps are not legal in California, most residents interested in sports betting in California now use prediction market platforms to speculate on sports outcomes.

Here is how to get started with one of our top prediction market apps if you live in California:

1. Choose a prediction market platform

Select one of the top prediction market platforms available in California. Options include popular trading apps such as Kalshi or Polymarket. Other options include ProphetX and OG, both federally and CFTC-regulated trading apps with a strong focus on sports trading outcomes, featuring game markets for the Rams, Chargers, Dodgers, Lakers, and other California-based professional teams.

2. Create an account

Sign up using your email address and complete the required registration process. To claim the current welcome offer, click on one of our SI-Verified links or input one of the provided promo codes from this page when prompted.

• 🟢 Kalshi promo code: VIP60
• 🔵 Polymarket promo code: SIBONUS
• 🧙‍♂️ ProphetX promo code: SICOM
• ➡️ Novig promo code: SIBONUS
• 🐶 Underdog promo code: SICOM
• 🟠 OG promo code: SIBONUS
• ➕ Plus500 promo code: SICOM

3. Verify your identity

Most prediction market platforms require identity verification to comply with federal regulations and financial laws.

4. Deposit funds

Link a bank account, debit card, or approved payment method and fund your account.

5. Browse available sports markets

Look for contracts tied to sporting events, championship outcomes, season-long futures, or game-specific markets. Many of the prediction market platforms on this page are also among the top NFL prediction market apps.

6. Buy and sell contracts

Prediction markets allow users to trade 'Yes' or 'No' contracts tied to real-world outcomes, including sporting events. Rather than placing a traditional bet, you'll purchase contracts priced between $0.01 and $0.99 based on the market's estimated probability of an outcome occurring.

7. Track results and withdraw winnings

Once the event concludes, contracts settle at either $1 or $0. If your prediction is correct, you'll receive the full $1 value for each contract you own. If the outcome is incorrect, the contract becomes worthless.

Many prediction market users also choose to sell their contracts before settlement to lock in profits or limit losses as market prices change. After your position settles, you can withdraw funds or continue trading other markets.

California residents can't claim traditional sportsbook promos, but they can still take advantage of welcome offers from platforms that offer sports-related event contracts on the NFL and other real-world markets.  

These are the best prediction market promos and promo codes for California residents to use for NFL on for Week 7 matchups, including the San Francisco 49ers at Atlanta Falcons, and all season long:

Kalshi in California is one of the most accessible prediction market platforms available today. I found the interface easy to use on both desktop and mobile, and the platform offers a deep selection of sports event contracts across leagues like the NFL, NBA, MLB, and major international events.

The latest Underdog promo code SICOM lets eligible new users play $10 and get $50 in Bonus Entries. Make one qualifying $10+ play to unlock $50 in Bonus Entries. Your qualifying play does not need to win.

Daily fantasy sports (DFS) in California offer residents another legal way to engage with their favorite leagues and players, alongside prediction markets and beyond traditional sports betting, which is illegal in the state. Instead of wagering on a team or game outcome, DFS contests are based on the statistical performances of individual athletes. Players can build fantasy lineups or make player-based selections, depending on the available contest format.

Some of the top options for California DFS include:

• DraftKings Fantasy
• FanDuel Fantasy
• PrizePicks
• Underdog Fantasy
• Sleeper

Daily fantasy sports vs. prediction markets

Prediction markets allow you to trade event contracts on a specific game outcome, such as whether or not the Dodgers will win their next game. Daily fantasy sports, by comparison, require you to build a lineup of players and compete against other users based on those players' statistical performances rather than simply predicting a single outcome.

For Californians, both DFS and prediction markets are available, but they work very differently:

• 🎯 Prediction markets: Trade contracts on whether a specific outcome will happen (e.g., Will the Dodgers beat the Giants?).
• 🏆 Daily fantasy sports: Draft a lineup of players and compete based on their real-game statistics.
• 💵 Prediction markets: Potential returns are based on the contract price you buy or sell.📊 Daily fantasy sports: Your payout depends on how your lineup performs relative to other entrants or the contest's prize structure.
• ⚖️ Prediction markets: Focus on forecasting a single event or market outcome.
• 👥 Daily fantasy sports: Requires managing multiple players across one or more games.

✅ California: Both prediction markets and DFS are widely accessible and legal, while traditional online sportsbooks remain unavailable in the state.

California is home to more major professional sports franchises than any other state, creating no shortage of betting and prediction market opportunities.

California sports betting fans can follow several major football events this week, including USC's highly anticipated home matchup against Ohio State and the first Chargers-Rams regular-season meeting of 2026.

Here are the major events for the week of Oct. 26–Nov. 1, 2026:

The California football slate features two notable Saturday college matchups. Cal visits NC State at noon ET, while USC hosts Ohio State at 7:30 PM ET in a sold-out Big Ten showdown. The Buckeyes enter the matchup with a 6-1 record, while USC is looking to recover from its second loss of the season.

In the NFL, Chargers-Rams at 4:05 PM ET on Nov. 1 gives California traders a head-to-head matchup between the state's two Los Angeles teams. The Rams improved to 3-4 with Sunday's victory over the Raiders, while San Francisco enters its Week 8 bye at 6-1 after losing 29-20 to Atlanta.

How California sports betting works on prediction markets

Traditional online and retail sportsbooks remain illegal in California, so California sports betting fans interested in NFL and college football outcomes can explore sports event contracts on eligible prediction market platforms.

These platforms offer contracts covering NFL games, college football and season-long futures. Available markets can include game winners, spreads, totals and player outcomes, depending on the platform and applicable restrictions.

Contract prices reflect the market's implied probability, so a 59¢ contract on the 49ers represents roughly a 59% market-implied chance of that outcome.

Prediction markets operate under a different regulatory framework from traditional sportsbooks, although the legality of sports event contracts remains subject to ongoing legal challenges.

What to know about California sports betting and prediction markets on October 30, 2026

Is sports betting legal in California? Traditional online and retail sportsbooks are not legal in California. Eligible prediction market platforms offer sports event contracts under federal commodities regulation, although their legal status remains contested, including restrictions arising from litigation involving tribal lands.

What California games can I follow this week? The main events are Cal at NC State and USC vs. Ohio State on Saturday, Oct. 31, followed by Chargers vs. Rams on Sunday, Nov. 1 at 4:05 PM ET. The 49ers have a Week 8 bye.

How do prediction market prices work? Sports event contracts commonly trade between 1¢ and 99¢, reflecting the market's implied probability of an outcome. A winning Yes contract generally settles at $1, while losing contracts settle at zero.

Can I trade California futures? Yes, where available and permitted. Prediction markets offer Super Bowl 2027 winner and conference championship futures alongside individual game markets. Available contracts vary by platform and eligibility.

Updated Oct. 26, 2026. Schedules, contract availability and market prices may change.

For Californians frustrated by the state's ban on legal sportsbooks and the inability to use top sportsbooks, prediction markets offer the best practical alternative.

Prediction markets allow users to buy and sell contracts tied to real-world outcomes. Rather than placing a traditional bet with a sportsbook, participants trade contracts whose value rises or falls based on the likelihood of an event occurring.

Because leading prediction market operators are federally regulated, they can generally offer sports-related event contracts nationwide, including in California.
