California voters crushed the nation's first proposed billionaire wealth tax Tuesday, rejecting Proposition 40 by 52.8% to 47.2% — a plain rebuke of the idea that punishing success is any way to fund a state.
The stakes are straightforward: when politicians tax wealth instead of income, they don't soak the rich — they drive jobs, investment, and tax revenue across state lines. Californians have watched that movie before. They voted to stop the sequel.
Prop 40 would have slapped a one-time 5% tax on anyone with a net worth above $1 billion, retroactive to January 1, 2026, with 90% of the revenue earmarked for healthcare. The Service Employees International Union-United Healthcare Workers West, which sponsored the measure, claimed it would generate around $100 billion.
But the coalition against Prop 40 was bipartisan and broad — and that's what the establishment press keeps soft-pedaling. NBC News framed the defeat as "a blow to the left." The Guardian went further, headlining that "California billionaires won." Both outlets buried the real story: opposition wasn't just tech moguls protecting their own. Governor Gavin Newsom, gubernatorial candidate Xavier Becerra, the California Teachers Association, the California Medical Association, and even Planned Parenthood Affiliates of California all came out against it. When Bernie Sanders and Ro Khanna are the marquee names on your side, and Planned Parenthood is on the other, the coalition problem should speak for itself.
Newsom backed Proposition 42 instead, which bans any new wealth tax on personal property. "Proposition 40 risked California's economic competitiveness and fiscal stability, as well as the revenue we rely on to fund our top priorities," opponents told the LA Times.
The opposition campaign was the most expensive in state history — nearly $425 million, according to The Guardian, with Google co-founder Sergey Brin alone contributing at least $132 million. Other donors included Eric Schmidt, Peter Thiel, and executives from DoorDash, Stripe, and Reddit. Opponents outspent supporters 250 to 1 on ads in late October, per NBC, citing AdImpact.
Opponents also placed two counter-measures on the ballot — Propositions 41 and 42 — designed to nullify Prop 40 even if it passed. Supporters called them "poison pills." The strategy worked.
Geography tells the real story. San Francisco County backed Prop 40 at 56.2% and Los Angeles County at 55%, according to the New York Post. Orange County rejected it at 59.3% and San Diego at 54.3%. The coastal enclaves wanted the tax. The rest of the state, where people actually run businesses and sign paychecks, did not.
SEIU-UHW leaders vowed to put another billionaire tax on the 2028 ballot if healthcare problems aren't addressed. The question now is whether California's leadership takes the hint — that voters understand what the lobbying class refuses to admit — or whether we get the same play with a different number next cycle.
