# California Voters Reject Billionaire Wealth Tax Proposal in Record-Spending Campaign Proposition 40, a one-time 5% levy on billion-dollar net worths, failed at the ballot box. - **Source:** [CBS News – Latest](https://www.cbsnews.com) - **Published:** 2026-11-10 - **Topic:** [politics](https://brifing.si/c/politics) - **Original article:** - **On Brifing:** https://brifing.si/s/7bc40ef2-c5ff-4c75-8a79-3c1d0531f411 ## Ballot Measure Rejection California voters have officially rejected Proposition 40, a proposed one-time 5% tax on residents with a net worth of $1 billion. The measure aimed to generate $100 billion over five years, primarily to fund healthcare programs. This defeat concludes a high-stakes campaign that shattered state spending records for tax-related initiatives. ## Economic Inequality Debate Supporters framed the vote as a critical struggle against economic inequality and the political influence of the billionaire class. Proponents argued that the state required additional revenue to offset federal healthcare cuts from the 2025 One Big Beautiful Bill Act, which impacted hospitals, emergency rooms, and essential Medi-Cal services. ## Democratic Party Division The proposal created a rare rift among traditional Democratic allies. While the California Democratic Party and SEIU Healthcare Workers West supported the measure, Governor Gavin Newsom and former Representative Katie Porter opposed it. They argued that such a tax would drive wealthy residents out of state, ultimately damaging long-term fiscal stability. ## Billionaire Opposition Coalition A coalition of wealthy individuals, including Sergey Brin, Larry Page, Peter Thiel, and John Doerr, organized against the measure. They funneled tens of millions into the group Building a Better California, which raised over $250 million by October 28. This funding also supported competing measures, Propositions 41 and 42, to limit taxes. ## Conflicting Revenue Projections Projections regarding the tax's impact varied significantly. A Stanford University study suggested that the tax might only generate $30 billion, far below the $100 billion estimate. The study noted that billionaires like Brin and Thiel had already removed $540 billion, or 30%, of California's billionaire wealth from the state's potential tax reach. ## Economist Perspectives Nobel laureates Daron Acemoglu and Joseph Stiglitz supported the measure, citing an open letter noting that billionaires paid only 1.6% of their $1.4 trillion wealth gain in income taxes between 2019 and 2025. They argued that this rate is significantly lower than the tax burden carried by ordinary California working taxpayers. ## Nvidia CEO's Stance Nvidia CEO Jensen Huang, with an estimated net worth of $200 billion, was a notable billionaire supporter of the tax. Huang stated he does not mind paying higher taxes as his earnings increase, provided the funds are not wasted. He emphasized his support for the values that the country represents. ## Future Policy Implications The failure of Proposition 40 serves as a bellwether for national debates on taxing extreme wealth. With the state's fiscal position now dependent on existing revenue streams, policymakers face ongoing pressure to address healthcare funding gaps without alienating the high-net-worth individuals who contribute significantly to the state's robust economic ecosystem. ## Sources covering this story - [CBS News – Politics — California Voters Reject Billionaire Wealth Tax Proposal](https://www.cbsnews.com/news/california-proposition-40-billionaire-wealth-tax-rejected-cbs-projects/) - [CBS News – Latest — California Voters Reject Billionaire Wealth Tax Proposal](https://www.cbsnews.com/news/california-proposition-40-billionaire-wealth-tax-rejected-cbs-projects/) - [de Volkskrant — California Voters Reject One-Time Wealth Tax on Billionaires](https://www.volkskrant.nl/buitenland/liveblog-politiek-vs-trump-amerika~be80fb9e/) - [Los Angeles Times – World & Nation — California Voters Reject Billionaire Tax Proposal](https://www.latimes.com/business/story/2026-11-09/billionaire-tax-prop-40-was-officially-rejected-in-california) - [NBC News – Top Stories — California Voters Reject Billionaire Tax Proposal](https://www.nbcnews.com/politics/2026-election/california-reject-billionaire-tax-ballot-measure-prop-40-rcna603382) - [Source — California Voters Reject Billionaire Tax Proposal](https://www.nbcnews.com/politics/2026-election/california-reject-billionaire-tax-ballot-measure-prop-40-rcna603382) - [France 24 – International — California Voters Reject Billionaire Wealth Tax Proposition](https://www.france24.com/en/americas/20261110-california-voters-reject-proposed-one-time-tax-on-billionaires-wealth) - [Le Monde in English — California Voters Reject Billionaire Tax Proposal](https://www.lemonde.fr/en/international/article/2026/11/10/california-voters-reject-billionaire-tax-designed-by-french-american-economists_6776662_4.html) - [CalMatters — California Voters Reject Proposition 40 Billionaire Wealth Tax](https://calmatters.org/politics/elections/2026/11/prop-40-billionaire-tax-defeated/) - [Source — California Voters Reject Landmark Billionaire Wealth Tax Proposal](https://www.france24.com/en/americas/20261110-california-voters-reject-proposed-one-time-tax-on-billionaires-wealth) - [Los Angeles Times – California — California Voters Reject Billionaire Tax Proposal Amid Economic Concerns](https://www.latimes.com/business/story/2026-11-09/billionaire-tax-prop-40-was-officially-rejected-in-california) - [Japan Today — California Voters Reject Billionaire Wealth Tax Measure](https://japantoday.com/category/world/california-voters-reject-measure-to-tax-the-wealth-of-billionaires) - [ABC News – Politics — California Voters Reject Billionaire Wealth Tax Measure](https://abcnews.com/Politics/wireStory/california-voters-reject-measure-tax-wealth-billionaires-137998961) - [TechCrunch — California Voters Reject Proposition 40 Billionaire Wealth Tax](https://techcrunch.com/2026/11/09/californias-proposed-billionaire-tax-fails-to-pass/) - [Technology & the Internet — California Voters Reject Billionaire Tax Proposal Amid Economic Concerns](https://www.latimes.com/business/story/2026-11-09/billionaire-tax-prop-40-was-officially-rejected-in-california) - [taz — California Voters Reject Proposed Wealth Tax on Billionaires](https://taz.de/Volkabstimmung-ueber-Reichensteuer-in-Kalifornien-scheitert/!6228844/) - [France 24 – International — California Voters Reject Billionaire Wealth Tax Measure](https://www.france24.com/en/video/20261110-california-voters-reject-measure-to-tax-the-wealth-of-billionaires) - [Il Sole 24 Ore – Mondo — California Voters Reject Proposed Five Percent Billionaire Wealth Tax](https://www.ilsole24ore.com/art/la-california-dice-no-tassa-5percento-i-miliardari-AJKLI9AC) - [CBS News – MoneyWatch — California Voters Reject Billionaire Wealth Tax Proposal](https://www.cbsnews.com/news/california-proposition-40-billionaire-wealth-tax-rejected-cbs-projects/) - [Source — California Voters Reject Billionaire Wealth Tax Measure](https://www.france24.com/en/video/20261110-california-voters-reject-measure-to-tax-the-wealth-of-billionaires) - [El País English — California Voters Reject Billionaire Wealth Tax Proposal](https://english.elpais.com/usa/2026-11-10/california-rejects-proposal-to-tax-the-wealth-of-states-billionaires.html) - [PBS NewsHour – Politics — California Voters Reject Landmark Billionaire Wealth Tax Measure](https://www.pbs.org/newshour/politics/california-voters-reject-tax-on-net-worth-of-billionaires) - [PBS NewsHour — California Voters Reject Landmark Billionaire Wealth Tax Measure](https://www.pbs.org/newshour/politics/california-voters-reject-tax-on-net-worth-of-billionaires) - [CalMatters — California Voters Reject Wealth Tax Proposal Targeting Billionaires](https://calmatters.org/calmatters-en-espanol/2026/11/rechazan-prop-40-impuesto-multimillonarios/) --- _Summary written by Brifing from the original reporting.
