California Secretary of State Shirley N. Weber certified the "One-Time Wealth Tax for State-Funded Health Care Programs Initiative" for the November 3, 2026 ballot on June 17-18, 2026. The measure would impose a one-time 5% tax on California residents with net worth above $1 billion, assessed as of January 1, 2026, with payments starting in 2027. Ninety percent of revenues would fund healthcare. The remaining ten percent would go to education and food assistance. SEIU-UHW drove the campaign to over 1.55 million valid signatures — nearly double the required threshold. The measure targets roughly 213 California billionaires holding $2.2 trillion in collective wealth. Google co-founder Larry Page moved his business entities to Delaware in December 2025 to sidestep the tax. PayPal co-founder Peter Thiel has donated $3 million to kill it.

1. The Money Is There, and Hospitals Need It (SEIU-UHW, Rep. Ro Khanna)

Labor's argument is simple: billionaires hold two trillion dollars in California wealth and pay almost nothing in state taxes.

Billionaires here pay almost nothing in state taxes. Emmanuel Saez, an economist at UC Berkeley, and colleagues calculated that the state's billionaires collectively pay roughly $3-4 billion in annual state income taxes on $2.2 trillion in wealth. That's less than 0.2% of their net worth. A 5% one-time tax spread over five years raises $100 billion — more than 25 times what they pay in a single year.

SEIU set the January 1 date to block an escape. The tax applies to California residents as of January 1, 2026 — before the November vote. The ITEP expert team argues that even if some billionaires depart after that date, their 2026 residency still triggers the obligation. And even if some do leave, the income tax losses are minor. The state's billionaires pay only $3-4 billion in annual income taxes anyway, making departure losses negligible compared to the $100 billion wealth tax gain.

The healthcare stakes are immediate. Suzanne Jimenez, SEIU-UHW's chief of staff: "Healthcare workers are going to the ballot to prevent California hospitals and emergency rooms from closing." The federal One Big Beautiful Bill Act could strip $66-128 billion from Medicare and Medicaid funding over a decade, according to the California Hospital Association. Rep. Ro Khanna (D-CA-17): "It's a matter of values. We believe billionaires can pay a modest wealth tax so working-class Californians have Medicaid."

2. But the Founders Are Already Gone (Larry Page, Peter Thiel, Vinod Khosla)

Billionaires didn't wait for the November vote. The wealth exodus started in late 2025.

Larry Page moved first. The Google co-founder converted his family office Koop and several funding vehicles — Flu Lab, One Aero, Dynatomics — from California to Delaware in late December 2025, protecting an estimated $12.5 billion from the tax. By the time the ballot measure cleared petition review, six billionaires had publicly departed, removing an estimated $536 billion — roughly 30% of aggregate California billionaire wealth — from the tax base before a single vote was cast.

Stanford's Hoover Institution says California may net negative. Its study modeled more than 100,000 simulations and found that 71% of them yielded a negative net present value after accounting for lost income tax revenue from departures, averaging a net cost to California of $24.7 billion.

The fine print hits founders who can't easily sell. The bill taxes founders on their voting control percentage, not their economic ownership. DoorDash founder Tony Xu owns 2.6% of his company economically but controls 57.6% of votes — a potential tax bill of $2.62 billion on a stake worth $2.41 billion. Venture capitalist Vinod Khosla called Rep. Khanna's support a "commie tax" and predicted it will cause permanent damage to California's tech economy.

3. Still, Newsom Says This Bill Is Wrong (Gov. Gavin Newsom)

The most unusual part of this fight: a Democratic governor running an "all hands" campaign against a labor union ballot measure.

Newsom supports taxing billionaires. He opposes this bill. He personally met with SEIU's president in an effort to stop the initiative from reaching the ballot, and told Politico the effort was "all hands." Newsom worries the measure could drive billionaire investment out of state and cut funding for teachers, childcare, firefighting, and police.

The legal challenges could wipe out all the revenue. Legal analysts at Baker Botts and Hanson Bridgett identified two specific grounds for a court challenge. SEIU set the January 1 effective date before voters cast a single ballot — and analysts say that retroactive move may violate due process. And because the measure effectively singles out roughly 200 specific individuals, a "bill of attainder" challenge is also on the table. If courts invalidate it, none of the revenue materializes. Tax Foundation analysts Jared Walczak and Katherine Loughead warned that because of "aggressive design choices and possible drafting errors," some taxpayers could face an effective rate dramatically higher than 5%.

Left-leaning groups joined Newsom in opposing the measure. Common Dreams called them "unlikely bedfellows" — progressives who support wealth taxation in principle but think this specific implementation is legally vulnerable and sets a bad precedent.

Where This Lands

SEIU-UHW and Rep. Khanna argue that $100 billion in healthcare funding is available from California billionaire wealth, and that the January 1 effective date locks in most of it before anyone can leave. Tech founders and their backers counter that the wealth has already moved, and the Hoover Institution study suggests the state could come out net negative after accounting for the billionaires who've already gone. Gavin Newsom and a coalition of left-leaning critics agree the wealthy should pay more but think this specific bill will collapse in court before collecting a dollar. California voters decide on November 3.
