You can gamble online in California in exactly one way: betting on horse races through a licensed advance deposit wagering platform. Online casinos, online poker, and online sports betting are not legal in the state. Daily fantasy sports operates in a gray area, and sweepstakes casinos, which many Californians have used as a workaround, become illegal on January 1, 2026.
Horse Race Betting Is the Only Legal Option
California authorizes online wagering on horse races through advance deposit wagering. Under Business and Professions Code Section 19604, the California Horse Racing Board can license racing associations, racing fairs, and wagering hubs to accept deposits and bets online or by phone.1California Legislative Information. California Code BPC 19604 You fund an account with a licensed platform, then place bets on races at California tracks and elsewhere. That’s it. If you want to bet real money over the internet from within California and stay on the right side of state law, horse racing is the option.
Online Casinos, Poker, and Sports Betting Are Not Legal
California Penal Code Section 330 makes it a misdemeanor to run or play any banking or percentage game for money, with penalties of $100 to $1,000, up to six months in county jail, or both.2California Legislative Information. California Penal Code Section 330 The statute predates the internet and names old games like faro and monte rather than online platforms, but no California law authorizes online casino games or online poker, and there is no licensing framework for them. The state has 79 licensed brick-and-mortar card rooms operating legally, and none are authorized to offer games online.3California Gambling Control Commission.

Sports betting is the same story. After the Supreme Court struck down the federal ban in Murphy v. NCAA in 2018, many states legalized it.5Supreme Court of the United States. Murphy v. National Collegiate Athletic Association, No. 16-476 California voters rejected two competing sports betting ballot measures in November 2022 by roughly two-to-one margins. Proposition 26 would have allowed in-person betting at tribal casinos and horse racing tracks. Proposition 27 would have authorized statewide online and mobile sports betting. Both failed, and neither has been replaced. There is no legal way to place an online sports bet from California.
Sweepstakes Casinos: Legal Now, Illegal in 2026
Sweepstakes casinos have been the most popular workaround for Californians. These sites use a dual-currency model: you buy a virtual currency for entertainment, and a second “sweepstakes” currency comes free with each purchase. The sweepstakes currency plays on games that look and feel like slots, poker, and table games, and winnings in that currency redeem for cash. Operators argued the structure sidestepped gambling laws because you were technically buying coins, not placing bets.
California ended that argument with Assembly Bill 831, which takes effect January 1, 2026. The law adds Penal Code Section 337o, making it illegal to operate an online sweepstakes game that uses a dual-currency system, simulates gambling, and awards cash or cash equivalents. Liability extends to vendors, payment processors, and others who knowingly support these platforms. Enforcement is already ramping up: in August 2025, the Los Angeles City Attorney filed a civil action against sweepstakes platform Stake.us under existing law. Legitimate promotional sweepstakes tied to actual product sales stay legal, so a soft-drink promotion or a fast-food scratcher isn’t affected.
Daily Fantasy Sports Is a Gray Area
Platforms like DraftKings and FanDuel have offered daily fantasy sports contests in California for years, but the legal footing is shaky. The California Attorney General has publicly stated that DFS contests are illegal under existing state gambling law. The operators argue DFS is a game of skill, not chance, and therefore falls outside the definition of gambling. No statute explicitly authorizes DFS in California, and no statute explicitly bans it.
UIGEA’s federal exemption for fantasy sports doesn’t settle the question either. That exemption just means DFS isn’t treated as unlawful internet gambling under federal law; it doesn’t override state law. Despite the Attorney General’s position, no major enforcement action has closed DFS in the state, and the platforms continue operating. If you play, you’re operating in legal uncertainty, though enforcement against individual players would be unusual.
Social Casino Apps Are Safe
Social casino games on Facebook and standalone apps simulate gambling with virtual currencies that can’t be redeemed for cash. These generally sit outside gambling laws because the prize element is missing: with no cash value, there’s no prize in the legal sense. Using a social casino app is not a legal risk. The line California draws, made sharper by the sweepstakes crackdown, is at the point where virtual currency becomes convertible to real money.
Offshore Sites and What You’re Actually Risking
Plenty of offshore online casinos, poker rooms, and sportsbooks accept California players. They operate outside California’s authority, and the state focuses its enforcement on operators rather than individual bettors. The realistic risk of criminal prosecution for placing a bet as a player is low.
The practical risks are different, and they matter more. You have no consumer protections. You have no way to resolve payment disputes. You have no recourse if the site refuses to pay out or disappears with your balance. Fraud on unregulated platforms is common, and state regulators have no jurisdiction to help you recover losses. Federal law also pushes against these sites at the payment layer: under UIGEA, banks and payment processors must identify and block transactions tied to unlawful online gambling, which is why deposits to offshore sites often get declined or reversed.6Office of the Law Revision Counsel. 31 USC Subchapter IV – Prohibition on Funding of Unlawful Internet Gambling
Taxes on Any Winnings You Do Have
Gambling winnings are taxable income even if the gambling wasn’t legal. Federally, the IRS requires operators to file Form W-2G when winnings meet or exceed $2,000 for 2026, a threshold that now adjusts annually for inflation. For many wager types, winnings also have to be at least 300 times the amount bet before reporting kicks in. Federal withholding at 24% applies when net winnings from sweepstakes, wagering pools, lotteries, or sports bets exceed $5,000 and hit the 300-times threshold.7Internal Revenue Service. Instructions for Forms W-2G and 5754
California taxes gambling winnings as income at your regular state rate. The one exception is California Lottery winnings, including SuperLotto, Powerball, and Mega Millions, which are exempt from state tax. All other gambling income, whether from a tribal casino, legal horse race betting, or an out-of-state or online source, is taxable. You can deduct gambling losses against winnings as an itemized deduction, but only up to the amount you won.8California Franchise Tax Board. Gambling – FTB.ca.gov The IRS expects you to report all gambling income on your return whether or not you receive a W-2G, so keep records of your wins and losses; the burden of proving deductible losses is on you.
The Short Version
Online horse race betting through a licensed advance deposit wagering platform is legal. Social casino apps that never pay real money are legal. Everything else Californians commonly ask about is either illegal, becoming illegal, or operating in a gray area the state has not blessed. Sweepstakes casinos close as a legal option on January 1, 2026. Daily fantasy sports continues in uncertainty. Offshore casinos and sportsbooks put you outside the protection of state and federal consumer rules, whatever the odds of personal prosecution. And if you do win, the tax bill is real.
