The $100 Billion Question: California's High-Stakes Vote on Ultra-Wealth

One hundred billion dollars. That is the amount of money Proposition 40 would raise from the wealthiest residents of California if the measure passes this November. The proposal would impose a one-time tax equal to five percent of the net worth of every individual in the state with a net worth of at least one billion dollars. There are just over two hundred such residents in California, including prominent figures like Oprah Winfrey, Mark Zuckerberg, Kim Kardashian, and George Lucas. The funds are intended to address significant federal cuts to the state's healthcare system.

Supporters of the initiative argue that this revenue is essential to prevent a collapse in healthcare services. Suzanne Jimenez, a representative for the Service Employees International Union-United Healthcare Workers West, described the measure as a short-term solution to a pressing crisis. She noted that without action, the system would deteriorate while longer-term funding strategies are developed. The tax would specifically target the extreme upper percentile of the wealth distribution, a strategy that public policy professor Francesco Trebbi at the University of California, Berkeley, believes makes this the first of its kind globally.

The proposal has drawn sharp criticism from key political and business figures. Governor Gavin Newsom, whose term is nearing its end, warns that the tax could incentivize wealthy residents to leave the state, thereby reducing income tax revenue. This concern is echoed by some billionaires who have already relocated. Larry Page, Sergey Brin, Peter Thiel, Travis Kalanick, and Don Hankey are among at least six billionaires who have reportedly moved away. Hankey told Forbes that the proposal made him feel unwanted despite the jobs his companies created.

Mark Zuckerberg, the head of Meta, disclosed to the company's board in September that he is considering moving his primary residence out of California. To mitigate the financial impact, Meta agreed to a new stock deal that grants him additional shares. Under the proposal, Zuckerberg could owe as much as twelve and a half billion dollars. Andy Fang, a cofounder of DoorDash, has publicly called the measure stupid, highlighting the strong opposition from the tech sector.

Polling data suggests the outcome remains uncertain. A September survey by the Los Angeles Times and the Berkeley Institute of Governmental Studies found that forty-five percent of likely voters are in favor, while forty-two percent are opposed. Thirteen percent of respondents remained undecided. Because a majority is required for the measure to pass, the undecided voters are crucial to the final result. Sergey Brin has reportedly given more than one hundred million dollars to a political organization funding ballot measures that aim to block the tax.

The tax would apply retroactively to anyone who was worth at least one billion dollars and lived in California as of January 1, 2026. This retroactive application adds a layer of complexity to the legal and financial implications for those affected. The state's decision comes at a time when economic inequality in the United States is near its highest level in over three decades, with the top one percent of households holding nearly thirty-two percent of total wealth.

Proponents like Senator Bernie Sanders argue that the tax addresses a deep-seated belief among the ultra-wealthy that they have a right to rule. He predicted that voters would send a powerful message on November 3. Dr. Kristian Niemietz of the Institute of Economic Affairs noted that while wealth taxes were once common in Europe, only Spain, Norway, and Switzerland retain them, often viewing such levies as more trouble than they are worth.

The vote fits into a broader national trend. Washington state voters are simultaneously considering a nine-point-nine percent tax on income over one million dollars. In California, seventy-two percent of residents believe the gap between the rich and the poor is widening, and a similar share thinks the state government should do more to address it. Trebbi suggests the measure is driven by an anti-elite sentiment, aiming to rebalance the economic scale rather than just solving a specific budgetary issue.
