In brief
Polymarket's prediction market gives Democrat Xavier Becerra a 92.7% probability of winning the 2026 California gubernatorial election. Recent polls confirm a commanding lead over Republican Steve Hilton, making Becerra the overwhelming favorite.
Introduction
California's 2026 gubernatorial race is shaping up to be a contest with a clear frontrunner. According to Polymarket data, Democrat Xavier Becerra is heavily favored to succeed term-limited Governor Gavin Newsom, while Republican Steve Hilton faces an uphill battle. With the election scheduled for November 3, 2026, the market reflects a broad consensus among bettors.
What to know
The California governor's race became a two-person contest after the top-two primary in June, where Becerra and Hilton emerged as the leading candidates. A recent PPIC poll, reported by the Los Angeles Times on July 15, 2026, shows Becerra with a commanding lead across all regions and party lines. Hilton, in response, characterized the race as 'wide open' and suggested Becerra's support is weaker than the poll indicates, as noted in the same article.
Becerra, former U.S. Secretary of Health and Human Services, has garnered support from nearly two-thirds of likely voters, according to a Newsweek article published July 16, 2026. Both sources agree that the race is heavily tilted in Becerra's favor, with Hilton needing a dramatic shift to close the gap.

The factors at play
- Polling dominance: Becerra leads by wide margins in recent surveys, with strong support across demographics.
- Incumbent party advantage: California has been reliably Democratic in statewide elections, and Becerra benefits from the party's organizational strength.
- Republican headwinds: Steve Hilton faces an uphill battle in a state where registered Democrats significantly outnumber Republicans.
- Ballot proposition context: Voter support for CEQA reform may energize centrist voters, but does not appear to shift the governor's race dynamics.
Our prediction
According to our analysis, the most likely outcome is Xavier Becerra. Polymarket currently assigns a probability of 92.7%, while our internal estimate is 95%. The difference stems from our assessment that the recent polls showing a commanding lead are robust and that no significant late-breaking scandal or event is likely to alter the trajectory. The market's 6.5% for Hilton appears to price in a small tail risk of a polling error or major surprise.
Risks and uncertainties
- Polling error: If the polls systematically overestimate Democratic support, Hilton could outperform expectations.
- National political climate: A wave election favoring Republicans could improve Hilton's chances.
- Late-breaking scandal: An unforeseen controversy involving Becerra could erode his lead.
- Voter turnout: Low turnout among Democratic-leaning groups could narrow the gap.
- Third-party or write-in surge: Although Chad Bianco is at 0.1%, any unexpected candidate gaining traction remains a remote risk.
Conclusion
Xavier Becerra is poised to win the California governorship in 2026, with strong poll numbers and a favorable political environment. While Steve Hilton remains in contention, the data and market odds suggest a comfortable victory for the Democrat. Bettors and observers should watch for any shifts in polling or major news events in the coming months.
