Online gambling for real money is not regulated or licensed in California. While the state permits legal gambling through land-based tribal casinos, the state lottery, licensed horse racing, and regulated card rooms, it does not authorize or oversee online sports betting, online casinos, or real-money online poker. As a result, Californians who wish to gamble online rely on offshore gambling sites that operate outside California’s regulatory framework but remain accessible via web browsers. There are no state-approved online gambling apps, and popular regulated sportsbook or casino apps block real-money wagering within California.

California’s gambling laws prioritize land-based and tribal exclusivity, with online gambling remaining in a legal grey area due to political conflicts among tribes, card rooms, and commercial operators that have stalled legalization efforts. The legal gambling age varies by activity, typically 21 for tribal casinos and 18 for the lottery and horse racing. Gambling winnings, whether from in-state or offshore online sources, are taxable as ordinary income under California law. Despite the widespread use of offshore platforms, California provides no regulatory oversight or consumer protections for online gambling, making player safety dependent on the reputation of the chosen site.
