California’s June 2 top-two primary is certified. Democrat Xavier Becerra finished first with 2,591,857 votes (28.0%), Republican Steve Hilton finished second with 2,277,318 (24.6%), and Democrat Tom Steyer finished third with 2,110,707 (22.8%). Becerra and Hilton advanced to the November 3 general election to succeed Gov. Gavin Newsom. See California’s certified Statement of Vote.

The live tracker above is now focused on the general-election winner market. DeFi Rate aggregates pricing from first-party exchange data; because venue volume measures are not always calculated on the same basis, use the venue-level figures rather than treating them as one combined editorial total.

California governor general election: Becerra vs. Hilton

Xavier Becerra (D) is the former US secretary of health and human services and a former California attorney general. He finished first in the certified primary with 2,591,857 votes (28.0%) and entered the general election as the clear prediction-market favorite.

Steve Hilton (R) is a former policy adviser and television host. He finished second with 2,277,318 votes (24.6%), securing the Republican spot on the November ballot. His market price remains well behind Becerra’s, but the live odds above will continue to respond to polling, endorsements, fundraising and campaign developments.

Tom Steyer (D) finished third with 2,110,707 votes (22.8%) and did not advance.

How these markets resolve

California governor winner: Candidate contracts resolve according to the rules published by each exchange for the November 3 general election. Traders should read the named resolution source, deadline and any recount or delayed-certification provisions on the specific contract.

Top-two primary advance: These contracts are resolved. A candidate’s Yes contract paid out if that candidate finished in the top two and advanced to November; Becerra and Hilton were the two successful outcomes.

Primary party composition: This market resolved to one Democrat and one Republican based on the two advancing candidates.

Key dates

  • June 2, 2026 — California held its top-two primary. Becerra and Hilton advanced, and the primary advance and party-composition markets resolved.
  • July 10, 2026 — The California Secretary of State certified the primary Statement of Vote.
  • October 5, 2026 — California counties begin mailing vote-by-mail ballots for the general election.

Market integrity and candidate trading

Kalshi previously sanctioned former governor candidate Kyle Langford after he traded on his own race, imposing a five-year trading ban and a $2,000 fine. The case remains a useful reminder that candidates and people with material nonpublic information can face exchange restrictions. Review each venue’s eligibility and prohibited-trading rules before participating.

What the California race could mean for 2028

The next governor will inherit one of the country’s largest state economies and a nationally visible office. The result could affect how both parties discuss California ahead of 2028, but this page’s live pricing is limited to the 2026 governor race.
