California Billionaire Tax Leads Poll but Faces Countermeasure Threats
By Drooid · · How we work
Core Event
California voters will decide on Proposition 40—a one-time, 5 % tax on the assets of billionaires who reside in the state as of Jan. 1, 2026—on Nov. 3, 2026. A recent Public Policy Institute of California (PPIC) poll shows 52 % of likely voters would vote “yes,” while 46 % would vote “no.” Two competing initiatives aim to nullify the wealth tax if they receive more votes: Proposition 41 would require state-auditor review of new taxes and invalidate those that exceed spending limits; Proposition 42 would bar taxes on financial assets such as stocks and retirement accounts. Under California law, if multiple measures on the same subject pass, the one with the higher vote total prevails.
Background & Context
Proposition 40 was drafted by SEIU United Healthcare Workers West to address funding gaps created by federal Medicaid cuts. The Legislative Analyst’s Office projects the measure could raise “tens of billions” for health-care and food-assistance programs. Critics, including Gov. Gavin Newsom and the major party candidates for governor, warn the tax could prompt wealthy residents to leave California. A coalition of billionaires, led by Google co-founder Sergey Brin, is promoting Propositions 41 and 42 to defeat the tax.
Data & Statistics
- Poll support (early September): Prop 40 52 % yes / 46 % no; Prop 41 51 % yes; Prop 42 54 % yes.
- Campaign spending: Opponents have booked roughly $100 million in airtime, spending $41.5 million against Prop 40 and $32 million supporting Propositions 41 and 42 since late July. Total opposition fundraising approaches $120 million.
Official Statements & Responses
Gov. Democratic gubernatorial candidate Xavier Becerra emphasized health-care funding, while Republican challenger Steve Hilton focused on fiscal restraint. Representatives of the billionaire coalition, organized under the “Building a Better California” banner, argue the counter-measures are necessary to protect taxpayers from an “unfair” levy.
Criticism & Opposition
Union leader Dave Regan, who heads the SEIU-UHW campaign for Prop 40, faces internal allegations of bullying and extortion. A confidential investigation by Barboza & Associates found multiple accounts of Regan’s threatening behavior toward female union leaders, which Regan denies, calling the claims “fabricated” and “absolute absurdity.” SEIU California spokesperson Christopher Calhoun said that “nothing justifies workplace violence,” underscoring the internal labor dispute surrounding the tax initiative.
Verbatim Quotes
- “The supporters of Prop. 40 have to think about and perhaps do something about the fact that so many people are supporting 41 and 42,” — Mark Baldassare, PPIC’s statewide survey director
- “Firstly, it’s a one-time tax, but this is not a one-time problem.” — Cristobal Young, university sociology professor
What’s Next
California voters will cast ballots on Nov. 3, 2026, deciding the fate of Proposition 40 and the competing Propositions 41 and 42. The PPIC poll indicates a narrow lead for the billionaire tax but highlights substantial support for the nullifying measures, setting the stage for a closely watched election.
