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.

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.
