Governor Gavin Newsom’s Opposition to California’s Billionaire Tax
By Drooid · · How we work
Proposition 40 and Newsom’s Stance
Proposition 40, on the November 3 ballot, would levy a one-time 5 % tax on the net worth of California residents whose wealth exceeds $1 billion as of January 1, 2026. Backed by a healthcare union, the measure is projected to raise about $100 billion to offset federal cuts to Medicaid, which serves roughly 15 million Californians. Governor Gavin Newsom opposes the tax, arguing it would drive wealthy entrepreneurs and their businesses out of the state and belongs at the national level.
Background & Context
California hosts more than 200 billionaires, making it one of the world’s most concentrated pockets of ultra-wealth. Federal budget reductions have left the state’s Medicaid program underfunded, prompting the proposal to tap billionaire wealth for a short-term fix. Wealth taxes elsewhere have produced modest revenue gains and reports of capital flight.
Key Figures & Groups
- Gavin Newsom – Governor, opposing Proposition 40.
- Lorena Gonzalez – President, California Federation of Labor Unions, supporting the tax.
- Saikat Chakrabarti – Co-founder of New Consensus, supporting the tax.
- Dave Regan – President, SEIU-UHW West, architect of the billionaire tax.
- Chris Larsen – Tech billionaire donating over $12 million to oppose the tax.
- Mark Zuckerberg – Meta CEO, negotiating a stock deal to offset a potential $12.5 billion liability.
Timeline
Data & Statistics
- Approximately 200 California billionaires would be taxed.
- The tax targets 5 % of each billionaire’s net worth, aiming to raise $100 billion.
- 45 % of likely voters support the measure, 42 % oppose it, and 13 % are undecided (Berkeley Institute of Governmental Studies & Los Angeles Times poll).
- Zuckerberg’s wealth exceeds $200 billion; the tax could cost him up to $12.5 billion.
Official Statements & Responses
Governor Newsom contends that a state-level billionaire tax would incentivize high-net-worth individuals to relocate, eroding income-tax revenue and harming the broader budget. Meta’s board approved a new non-voting class of shares for Zuckerberg to offset the prospective liability.
Criticism & Opposition
Labor leaders argue Newsom’s stance is driven by electoral calculations. Gonzalez warns many officials fear the “billionaire class.” Chakrabarti links Newsom’s opposition to his anticipated 2028 presidential bid, and Kessler notes electability concerns dominate Democratic primary considerations.
Why It Matters
If passed, Proposition 40 could provide a short-term infusion for California’s Medicaid system but may also trigger capital flight, as several billionaires have already begun relocating. Politically, Newsom’s opposition intertwines with his potential 2028 presidential campaign, influencing his alignment with centrist donors and moderate voters.
Verbatim Quotes
- “There are a lot of elected officials who are so afraid of this billionaire class,” — Lorena Gonzalez
- “He’s made no secret of it — he’s going to run for president. And that’s why he’s not just opposed to Prop. 40. He’s vehemently campaigning against it because he needs those billionaires on his side,” — Saikat Chakrabarti
- “It defuses him being the total lefty from California,” — Fernando Guerra
What’s Next
The November 3 ballot will decide whether California implements the nation’s first billionaire wealth tax. A majority “yes” vote would trigger the $100 billion levy; a “no” outcome would preserve the status quo and keep the debate over state versus national taxation alive as Newsom’s presidential ambitions continue.
