On November 3, 2026, California voters will vote on Proposition 40, a one-time 5% levy on the net worth of billionaires who were California residents on January 1, 2026. Ninety percent of the revenue would fund healthcare programs, with the remainder set aside for food assistance and education.

A small segment of the state’s 200-plus billionaires has stepped up to oppose Prop 40, contributing millions to opposition groups and vocally speaking out against the one-time fee.

In a brief report, California’s Billionaire Wealth Surge: Meet the 22 California Billionaires Opposing Prop 40 Billionaire Wealth Tax, we identified 22 California billionaires who are active funders and outspoken opponents of Prop 40. Together they have given over $150 million to oppose the initiative—with more rolling in every day. These 22 include a prince, several private jet flying chums of Jeffrey Epstein, and a bunch of crypto and tech bros designing the AI future for the rest of us.

Thiel’s wealth is 10,759 times the median wealth of a Californian household.

On January 1, 2025, these 22 billionaires had a combined wealth of $439.8 billion. By September 1, 2026, their wealth had grown to $722.1 billion.

In a little under 20 months, their combined wealth increased $282.6 billion, a gain of over 64%.

Just to be clear, these “snowflake billionaires” are whining, wailing, and donating money to fight a tax that would effectively require them to part with one-eighth of the wealth they’ve gained since January 1, 2025.

This group includes Google’s Sergey Brin who has been the single largest opposition donor, chipping in over $102 million to fight Prop 40. Brin has seen his wealth grow a whopping 70% in the last 20 months, from $148 billion on January 1, 2025 to $253 billion on September 1, 2026. Brin’s wealth is 83,498 times the median wealth of a Californian household, which is $303,000.

Palantir’s Peter Thiel gave $3 million to the No on 40 campaign and has called on other billionaires to move out of California. In the last 20 months, Thiel’s wealth increased a whopping 120.27%, from $14.8 billion on January 1, 2025 to $32.6 billion on September 1, 2026 (Forbes). Thiel’s wealth is 10,759 times the median wealth of a Californian household.

Chris Larsen, founder of cryptocurrency firm Ripple, has given over $5 million to the No on Prop 40 Campaign, along with another $5 million from Ripple and $12 million to Building a Better California. His personal wealth increased 23.5%, from $10.2 billion to $12.6 billion in the last 20 months. His wealth is 4,158 times the wealth of the median California family.
