Brin funded $102 million fight on California billionaire tax

Google co-founder Sergey Brin has given more than $100 million to a campaign opposing a proposed California tax on billionaires, but he will not be eligible to vote on the measure himself after switching his voter registration to Nevada on December 10, 2025, 재경일보 reported.

Brin's representatives said he now lives in Nevada, where he bought a $42 million house on the state's side of Lake Tahoe. California Proposition 40, on the ballot with the midterm elections on November 3, 2026, would impose a one-time 5% levy on net worth above $1 billion for people who were California residents on January 1, 2026, with proceeds directed to health care, education and food aid. Because that assessment date falls after his move, the change affects both his vote and his exposure to the tax. His super PAC, Building a Better California PAC, has collected over $102 million.

Co-founder Larry Page relocated to Florida between December 2025 and January 2026, where he ranks second in wealth behind Jeff Bezos. Mark Zuckerberg and Jensen Huang now top California's list. Huang has said he intends to stay in the state regardless of the tax.

California counts about 255 billionaires, the most of any state, though their combined $1.81 trillion trails Texas at $1.82 trillion.
