At a high-profile Christmas party in a redwood treehouse, California Governor Gavin Newsom faced a stark warning from Sergey Brin, co-founder of Google, and his partner: they were leaving the state over a proposed billionaire tax. This confrontation marked the beginning of a major political battle as Brin and other ultrawealthy tech leaders launched a massive campaign to oppose the tax and reshape California’s political landscape.

The billionaire tax proposal has ignited unprecedented activism among Silicon Valley’s richest, injecting over $270 million into the state’s political scene. With the June 2 primary approaching, billionaires like Brin are backing candidates and initiatives that challenge the Democratic establishment, signaling a new era of high-stakes influence in California politics.

A Tense Encounter Sparks Billionaire Exodus

During a festive gathering hosted by crypto mogul Chris Larsen, Sergey Brin confronted Governor Newsom about the proposed wealth tax that threatened to significantly impact his $272.6 billion fortune. Despite Newsom’s opposition to the tax, Brin and his partner decided to relocate to Nevada, purchasing a $42 million mansion by Lake Tahoe. This move was not just personal but political, as Brin immediately began funding efforts to overturn the tax.

Billionaire Backlash Fuels Political Spending Surge

Brin’s departure catalyzed a wave of political donations from California’s ultrawealthy. In just four months, he has contributed over $58 million to anti-wealth tax campaigns and pro-business initiatives. Alongside other tech leaders like Eric Schmidt and Patrick Collison, Brin is spearheading a coalition to influence the state’s policies and elections, marking a significant shift from their previous low-profile political involvement.

  • Brin donated $20 million initially to Building a Better California, later adding $37 million.
  • Other billionaires such as Peter Thiel and Eric Schmidt have also contributed millions to oppose the tax.
  • The coalition supports candidates like Silicon Valley Mayor Matt Mahan and Republican Steve Hilton.
  • Tom Steyer, a billionaire Democrat, is running a progressive campaign advocating for the wealth tax.

The Governor’s Race: Billionaires on Opposite Sides

The 2024 governor’s race has become a battleground for billionaire influence. While Tom Steyer campaigns as a progressive champion of taxing the ultrawealthy, Brin and his allies back candidates who oppose the tax and challenge the Democratic establishment. Despite heavy spending, some backed candidates like Matt Mahan remain in single-digit polling, while Steyer gains traction with voters.

“You have two polar opposites going on. You have a billionaire running who has actually fully adopted an agenda that the vast majority of voters agree with: Taxing billionaires, funding healthcare, fighting back against ICE. And then you have billionaires pushing a candidate whose talking points are apologetic to the tech industry.”Lorena Gonzalez, California Federation of Labor Unions

Challenges and Skepticism in Billionaire Political Influence

Despite the influx of money, political insiders remain skeptical about the ultrawealthy’s ability to sway California politics. Past attempts by billionaires to win statewide office or pass major initiatives have often fallen short. Additionally, some donors treat political contributions like investments, withdrawing support if momentum stalls, raising questions about the durability of this new wave of billionaire activism.

Chris Larsen, a crypto billionaire, expressed concern over the lack of broader business engagement, emphasizing the need for more firepower to counter powerful unions like SEIU. Meanwhile, Governor Newsom acknowledges the wealthiest residents’ willingness to donate but stresses that many prefer to do so on their own terms rather than through taxation.
