Tech Billionaires Flood California Primary with Record Spending
6/2/2026, 1:16:18 AM
Core Event
Tech billionaires have spent hundreds of millions on California’s June 2, 2026 primary, backing governor-candidate Matt Mahan, opposing a 5 percent billionaire tax, and funding local races statewide.
Background & Context
Silicon Valley sees the primary as a chance to shape a five-year AI regulatory agenda. In 2025 the sector spent $39 million on state lobbying and $109 million on federal lobbying, outpacing oil-and-gas.
Key Players
Top donors are Google co-founder Sergey Brin ($66 million), Ripple Labs co-founder Chris Larsen ($26 million), and mayor-turned-candidate Matt Mahan (nearly $50 million). Critics include labor leader Lorena Gonzalez Fletcher and policy analyst Francesco Trebbi; watchdog John Bennett monitors the spending.
Money & Data
Tech contributions include $66 million from Brin to block the billionaire tax, $26 million from Larsen to three Super PACs, $10 million from Google and Meta for legislative races, $15 million to Grow California, $5 million each from Google and Meta to California Leads, and $39 million in state lobbying. Mahan polls at about 4 percent.
Responses
Official Statements
Professor Francesco Trebbi calls the flow a “cycle of economic power” that reinforces political influence. Matt Mahan says his record shows no industry-favoring actions and pledges a “fair-share” approach.
Criticism
Labor president Lorena Gonzalez Fletcher calls Mahan “opposed to the candidate funded by Trump’s big tech billionaires.” Chris Larsen told Politico that organized labor is “completely fucking owned by one side.” Mahan’s poll remains near 4 percent.
Tactics & Gaps
On-the-Ground
Voters in Oakland, Bakersfield and Orange County have received TV ads, robotexts and mailed guides from tech-funded Super PACs. The Deliver for California PAC, which supported Mahan, dissolved after a $500,000 spend.
Conflicting Reports
Campaign-finance filings capture only part of the outlay; analysts warn dark-money entities hide additional spending. Brin’s move to Nevada raises questions about his eligibility under California contribution limits.

- “I’m not running for tech, and if you look at my record – I’ve been in public office now for six years – I think you’d be hard pressed to find – you would not find a single example of me ever doing something to benefit the industry to the detriment of the community,” — Matt Mahan, gubernatorial candidate
- “opposed to the candidate funded by Trump’s big tech billionaires” — Lorena Gonzalez Fletcher, California Labor Federation president
What’s Next
The November ballot will decide the 5 percent billionaire tax, while June primary results will show whether tech spending translates into legislative influence. Ongoing investigations into undisclosed contributions may reveal further hidden spending.
