California’s billionaire class features prominent figures like Dr. Dre, Tim Cook, Marissa Mayer, Mark Zuckerberg, Beyoncé, and Jay Z. These individuals represent a fraction of the state’s wealthy elite wielding significant influence in the political arena.
In the 2026 election, a few exceptionally wealthy people used their resources to impact the political scene statewide. POLITICO conducted an analysis revealing insights into the billionaires’ political affiliations and voting patterns.
High-Spending Campaigns
Some billionaires have made their political ambitions clear. Philanthropist Tom Steyer spent over $200 million in a bid for the governor’s office but failed to secure the nomination. Meanwhile, an opposition campaign against Proposition 40, aimed at imposing a temporary tax on the wealthiest residents, saw over $300 million in spending. This effort was led by Sergey Brin, poised to become a significant political figure.
Gary Michelson, a surgeon and inventor, spent tens of millions promoting an immunology bond directing funds to a co-founded institute. In total, these and other billionaires have spent a record $612 million on the state’s election.
The Billionaire Demographic
Forbes lists over 250 billionaires residing in California, with POLITICO matching 166 of them to the state’s voter files. This data offers insights into their political tendencies and party affiliations.
Famous names from entertainment and tech, such as Dr. Dre, Rihanna, Kim Kardashian, and Mark Zuckerberg, are included. Others, like Donald Friese and James Scapa, operate more discreetly in their business ventures.
Political Affiliations
POLITICO’s analysis found more registered Democrats among these billionaires than Republicans, which contrasts the common perception of wealth being linked to Republican support. Despite notable interactions with past presidents, like Donald Trump, some high-profile billionaires remain Democrats.
Zuckerberg, despite his interactions with Trump, is registered as a Democrat. The same applies to Dario Amodei and Sam Altman, key figures in the tech industry. Prominent Republicans among California billionaires include former Governor Arnold Schwarzenegger and Joe Lacob, owner of the Golden State Warriors.
Billionaires tend to have no party preference at nearly double the state average, reflecting a possible disillusionment with the two-party system. Paul Mitchell, a political expert, suggests a sense of independence might drive this trend.
Geographical Concentration and Voting Habits
Los Angeles and San Francisco serve as key centers of billionaire influence, with over 30 registered in San Francisco and 15 in Los Angeles. Many are native Californians, with others hailing from New York and various international locations.
Despite their notable presence, billionaires remain active voters, with over 60% participating in the last three presidential elections. However, turnout drops in special elections and primaries, as seen in November’s special election with 54% participation.
