California Billionaires Clash Over Proposed Wealth Tax
4/30/2026, 9:07:48 AM
Proposed One-Time 5% Wealth Tax
A ballot initiative backed by the Service Employees International Union-United Healthcare Workers West seeks a one-time 5 % tax on assets of California residents with net worth over $1 billion as of Jan. 1, 2026, projected to raise $100 billion, 90 % for health-care.
Political Context and Signature Drive
Over 1.5 million signatures—well above the ~870,000 needed—have been submitted for the November ballot. Proponents cite federal health-care cuts from the 2025 “One Big Beautiful Bill,” while opponents say the draft is flawed and could trigger a wealthy-resident exodus.
Key Players
Google co-founder Sergey Brin has poured $57 million into the anti-tax Super-PAC Building a Better California. Governor Gavin Newsom has vowed to block the levy. Brin’s girlfriend, Trump-supporting influencer Gerelyn Gilbert-Soto, appears with labor advocates Liz Perlman (AFSCME) and Mayra Castañeda, who back the proposal. The California Business Roundtable, backed by Larry Page and Peter Thiel, leads the opposition.
Official Positions
Newsom warned the tax would “drive wealthy residents and investment out of the state” and vowed to block it. SEIU says levy is to keep hospitals open. Building a Better California argues tax would harm economy, shrink budget and raise living costs for families. Secretary of State Shirley Weber has not certified petition.
Criticism
The California Business Roundtable, backed by Larry Page and Peter Thiel, says the tax would undermine the economy, shrink budget and raise living costs for families. Political scientist Jack Pitney warned the fight could jeopardize Newsom’s 2028 presidential bid. Tax consultant David Lesperance called the initiative a “Tax the Rich” wildfire that spurred “fire-escape plans” among billionaires.
Conflicting Reports and Gaps
Sources differ on Brin’s contribution ($45 million vs $57 million) and net worth ($260 billion, $265 billion, $273 billion). The signature threshold is cited as 870,000 or 875,000. Estimates of California’s billionaire count range from 25 individuals to “a few hundred,” leaving the tax’s true scope uncertain.
Verbatim Quotes
- “I fled socialism with my family in 1979 and know the devastating, oppressive society it created in the Soviet Union. I don’t want California to end up in the same place.” — Sergey Brin, Google co-founder
- “Hospitals are closing and people will die,” — Liz Perlman, AFSCME executive director
- “It’s one of the reasons why Newsom’s path to the Democratic nomination is not going to be an easy one,” — Jack Pitney, political scientist
- “In fact, because the state relies so heavily on high-income-earner tax revenue, this measure could lead to reduced budget revenue in the long term as highly mobile, wealthy individuals leave the state to avoid this new tax,” — Rob Lapsley, California Business Roundtable president
Outlook and Next Steps
The Secretary of State must verify the signatures before the initiative appears on the November ballot. Both pro- and anti-tax coalitions have pledged additional spending, foreshadowing a costly campaign. If approved, the tax could reshape California’s fiscal landscape and inspire similar wealth-tax proposals elsewhere.
