Silicon Valley Billionaires Defeat California Wealth Tax Proposal
California voters have rejected a proposed 5% wealth tax on billionaires following a record-spending campaign led by Silicon Valley tech executives. Opponents argued the levy would drive capital out of the state, while supporters vowed to continue their fight.

Silicon Valley billionaires have secured a major victory after California voters rejected a high-profile wealth tax proposal during the midterm elections. According to the final vote count, approximately 54% of voters opposed the measure, while 46% supported it, bringing an end to an exceptionally costly political battle that pitted tech founders, venture capitalists, and senior executives against labor unions.
The Billionaires' Coalition and Strategy
Known informally as "The Avengers," a core group of roughly 24 tech leaders held weekly conference calls, analyzed polling data, and coordinated advertising efforts to defeat the measure. Approximately 80 donors poured more than $333 million into the Building a Better California campaign. The coalition was spearheaded by Google co-founder Sergey Brin, who contributed $102 million, alongside former Google CEO Eric Schmidt, venture capitalist John Doerr, and Stripe CEO Patrick Collison.
Economic Debate and Political Divisions
Supporters argued that the one-off 5% levy on fortunes exceeding $1 billion would have raised roughly $100 billion over five years to fund healthcare systems bracing for federal funding cuts under the Trump administration. Opponents countered that the tax would drive entrepreneurs and capital out of the state toward Nevada and Texas, ultimately harming long-term public revenues. The debate split the Democratic Party, with Senator Bernie Sanders backing the tax, while California Governor Gavin Newsom opposed it over economic concerns.
Broader Electoral Outcomes
Alongside the defeat of the wealth tax, voters advanced Proposition 42, backed by heavy financial backing from the business community, which aims to constitutionally restrict future asset-based taxes. However, voters simultaneously approved a measure to maintain high income tax rates for top earners, underscoring a nuanced public sentiment toward taxation in the state.
