Sergey Brin Surpasses $100 Million in Funding to Oppose California Billionaire Tax
Google Co-Founder Continues Significant Capital Commitment Against Proposed Wealth Levy
CALIFORNIA – August 12, 2026 – Google co-founder Sergey Brin has now directed more than $100 million toward efforts opposing California’s proposed one-time billionaire tax, according to recent filings. The latest contribution brings his total support for the campaign past the nine-figure threshold.
The proposed measure would impose a 5 percent tax on the net worth of approximately 200 billionaires residing in the state. Brin, currently ranked among the world’s richest individuals, has been one of the most prominent financial backers of organized opposition to the initiative.
The scale of the commitment reflects the intensity of the debate surrounding extreme wealth taxation in California and the willingness of top-tier technology founders to deploy substantial personal capital in the policy arena.
