California Billionaire Tax Measure Certified for November Ballot
6/26/2026, 6:30:14 AM
Background
The Service Employees International Union-United Healthcare Workers West (SEIU-UHW) drafted a one-time 5 % levy on the net worth of California residents with assets over $1 billion as of Jan. 1 2026. Ninety percent of the projected $100 billion would fund Medi-Cal and 10 % food assistance and education. SEIU-UHW spent $7.3 million to qualify the initiative and has a campaign budget exceeding $31 million.
Key Players
Supporters: SEIU-UHW, Senator Bernie Sanders, Ro Khanna.
Opponents: Gov. Gavin Newsom, Google co-founder Sergey Brin, Ripple Labs co-founder Chris Larsen, California Business Roundtable, California Teachers Association, California Medical Association, Planned Parenthood Affiliates of California.
Data
About 200-250 billionaires. Projected $100 billion revenue; Legislative Analyst’s Office expects “tens of billions” early, with possible loss of “hundreds of millions” annually if wealth-flight occurs. Opposition spending exceeds $100 million (Brin $82 M, Larsen $13.2 M). Polls show 54 % support vs. 45 % oppose (PPIC) and 52 % support (UC Berkeley-Citrin).
Why It Matters
Proponents say the tax would stop hospital and emergency-room closures due to federal Medicaid cuts. Critics warn it could spur wealthy taxpayers to leave, threatening a budget that gets nearly half its income tax from the top 1 %.
Official Statements & Responses
Gov. Newsom says it is “poorly designed,” would “defund teachers, schools, clinics,” and risk driving wealth out of California. SEIU-UHW President Dave Regan calls tax essential to avoid “life-and-death” health crises and rejected a 2 % compromise. Senator Sanders calls it a template for national wealth tax. Rep. Khanna called capital-flight concerns “hogwash.” California Medical Association and Planned Parenthood warned one-time levy lacks sustainable funding path.
Criticism & Opposition
The California Teachers Association and State Building and Construction Trades Council say the tax threatens long-term revenue stability. Healthcare groups argue the retroactive valuation could spur asset relocation. Business leaders point to a provision allowing legislative amendment after passage as a risk to fiscal predictability.
Conflicting Reports & Gaps
Revenue estimates range from “tens of billions” to $100 billion. Billionaire counts vary between 200 and 250. Opposition spending figures differ: some cite Brin’s $82 million alone, others a combined $118 million. Poll results also vary.

The billionaire tax and two counter-initiatives will appear on the Nov. 3 ballot. Legal challenges over the retroactive valuation are expected. Campaign spending could top $400 million, making the contest one of California’s costliest ballot fights. Voter sentiment will be watched as an early gauge of progressive tax appetite ahead of 2028 primaries.
