Xavier Becerra holds a commanding lead in the California governor market following the June 2, 2026, nonpartisan primary, where early returns show him advancing alongside Republican Steve Hilton while Tom Steyer trails in third. Becerra’s position stems from his record as state attorney general and former U.S. Health and Human Services secretary, combined with broad Democratic consolidation that limited vote splitting among other party contenders. Steyer’s billionaire background drew opposition spending and limited his primary support. In a state with consistent Democratic advantages in statewide contests, traders assign Becerra the highest implied probability for the November general, though Hilton’s advancement creates the formal matchup and any late shifts in turnout or endorsements could still influence the outcome.
