San Jose Mayor Matt Mahan is joining the crowded race for California governor.

After teasing a potential run for the last few weeks, Mahan confirmed the news in an interview with the San Francisco Standard.

The 43-year-old became mayor of San Jose in 2023.

In a quote to the Standard, he said, “The past three years that I’ve been mayor have become a model for how we start to move the needle on issues that many people have thought were intractable.”

Mahan joins a very crowded field with 10 other candidates, including former Health and Human Services Secretary Xavier Becerra, former Rep. Katie Porter and investor Tom Steyer.

Mahan made it official Thursday morning via a post on social media.
