California has a long-standing tradition of horse racing, with iconic venues like Santa Anita Park and Del Mar racetrack. Betting on horse racing is legal and regulated by the California Horse Racing Board (CHRB), which oversees licensing, integrity, and ethical standards. Wagering is permitted at licensed racetracks, authorized satellite facilities, and through state-approved online platforms using advance-deposit wagering (ADW). These platforms ensure user verification to prevent underage and out-of-state betting, offering various bet types and live race access. Horse racing remains the only legal form of betting in California, as other sports betting and casino gambling are prohibited.

The CHRB works closely with racing associations, veterinarians, and law enforcement to maintain fair competition and animal welfare, while ensuring proper distribution of wagering profits to support the industry and public funds. California promotes responsible gambling through education, self-exclusion programs, and operator-provided tools to help bettors manage their activity. As technology advances, horse racing continues to be the most accessible and regulated betting option in the state, contributing to tax revenue and sustaining thousands of jobs.
