Although the California gubernatorial election isn't for another 300 days, this critical ballot series is a constant topic of discussion among U.S. news and prediction markets.

With the rise of prediction market apps, people have been trading on which Democratic or Republican nominees they feel will win the state election.

California Governor's Race Heats Up

Coverage of the 2026 California gubernatorial election is heating up. This high-stakes election — also known as the Governor's Race — will determine California’s next governor.

Current Democratic Governor Gavin Newsom isn't eligible to run for re-election, and the nonpartisan top-two primary will take place in June. Meanwhile, polls are bouncing between Republican and Democratic candidates on a daily and weekly basis.

Recently, news broke that Eric Swalwell, who was an early leader in the polls for the Democratic Party, announced his resignation from the race after sexual assault allegations.

However, when it comes time to determine who’s leading the race, there are ongoing discrepancies between traditional polls and prediction markets, especially Kalshi.

Some poll projections show Republicans Steve Hilton and Chad Bianco leading the race, with a crowded field of Democratic contenders trailing. Other analyses place Hilton in the lead, but with a Democratic candidate close behind.

These differences bring up questions about which platform is more trustworthy — the polls or the data seen on prediction markets? Polls have been criticized for their inaccuracies, while prediction markets involve trading on candidates for real money.

As highlighted above, the polls had Republicans leading at one point, while Kalshi features several Democrats leading the race.

Kalshi Predictions on Who's the Next California Governor
