Overview
- Late June the ballot measure officially qualified for the November 3, 2026 vote after proponents submitted more than 1.6 million signatures and cleared state review.
- The initiative, led by SEIU‑UHW and the Billionaire Tax Now coalition, would impose a one-time 5% tax on roughly 200 residents with more than $1 billion in net worth as of January 1, 2026 and direct most revenue to healthcare programs.
- Governor Gavin Newsom has publicly said he will oppose the state measure and instead calls for a national minimum tax on billionaires, creating a sharp split between the governor and progressive backers.
- Wealthy opponents have poured millions into resisting the measure, with reporting naming figures such as Sergey Brin among major funders, and the campaign now faces legal and valuation questions about enforcement and revenue certainty.
- Passage could set a model for other states and reshape debates over taxing extreme wealth, while failure would leave California to seek other ways to plug a large healthcare funding gap caused by recent federal budget changes.
