Billionaires Fund Opposition to California's Proposed Wealth Tax

Several prominent venture capital and crypto billionaires are funding efforts to oppose California’s proposed one-time wealth tax on individuals with a net worth exceeding $1 billion. Campaign finance records show significant contributions from Peter Thiel, Sergey Brin, Chris Larsen, and John Doerr toward political action committees fighting Proposition 40. Proposition 40 aims to raise an estimated $100 billion over five years for health care, food assistance, and education by taxing billionaires at a rate of up to 5%. Critics argue the tax could push wealthy entrepreneurs out of California. Mark Cuban recently joined the debate on social media, warning that passing Prop. 40 might deter startup founders from staying in the state. Economists like Emmanuel Saez suggest mechanisms such as deferral options can help billionaires pay their share gradually if they lack immediate liquidity.
