California Billionaire Tax Headed to November Ballot — Newsom Publicly Opposes It
Here's a political story that sounds like it's only about billionaires — but it's really about who pays for California's hospitals, schools, and safety net. And ultimately, that's a question every Californian has a stake in.
What happened
California Gov. Gavin Newsom is facing a major political headache: a massive wealth tax he warned could cause a business exodus from the state was officially added to the November ballot, despite his opposition. The measure, called the California Billionaire Tax Act, would impose a one-time, "emergency" 5% tax on Californians with assets exceeding $1 billion.
The group behind the tax effort — Billionaire Tax Now, sponsored by the Service Employees International Union – United Healthcare Workers West — pushed it forward without Newsom's blessing. The union argues the tax will "prevent the collapse of California healthcare and help fund California public K-14 education and state food assistance programs."
Why does it exist?
The measure was introduced in response to steep healthcare funding cuts resulting from President Donald Trump's "Big Beautiful Bill." Supporters say it could raise about $100 billion to help offset those federal Medicaid cuts. Under the initiative, roughly 90% of the revenue would be directed toward healthcare programs, with the remaining 10% earmarked for education and food assistance.
So why is Newsom — a Democrat — against taxing billionaires?
This is the twist that makes the story worth following. In a Substack post, Newsom wrote, "Last night, it became certain that a wealth tax would be placed on the November ballot in California. I'm voting no." His argument isn't that billionaires shouldn't pay more — it's that this particular approach will backfire. "You may not be able to pick up and move to Texas or Florida to shelter your income from taxation, but I promise you that billionaires can, and do," he wrote.
Newsom also says he opposes the ballot measure because the revenue would go to just one category of state spending — healthcare — while ignoring schooling, housing, and other issues.
The nonpartisan Legislative Analyst's Office estimates that while the tax would generate tens of billions initially, it would subsequently cause annual income tax revenues to drop by hundreds of millions of dollars.
The money on the opposition side
The nonprofit Building a Better California, which supports competing ballot initiatives designed to nullify the billionaire tax, has raised more than $118 million — $80 million of it from Google co-founder Sergey Brin. Six of the state's estimated 214 billionaires were reported to have left California before or around the January 1 deadline, including PayPal co-founder Peter Thiel, former Uber CEO Travis Kalanick, and Google co-founders Larry Page and Sergey Brin.
Newsom's pivot
Here's where it gets politically interesting. Rather than just opposing the state tax and moving on, Newsom proposed a national "billionaires' tax" — calling for a federal minimum tax rate on Americans worth more than $100 million, rather than a state-level one-time 5% levy that, he argues, could be dodged by billionaires who simply leave California.
Political science professor Dan Schnur at UC Berkeley called Newsom's move "savvy political positioning." "He's not against taxing billionaires, he just has a different way of doing it," Schnur said, adding that it gives Newsom "an answer for progressive Democrats" as to why he didn't support the state ballot measure. The subtext: Newsom is widely expected to run for president in 2028.
Why it matters to you
Even if you're not a billionaire (safe assumption), the outcome of this November vote could affect hospital funding, public schools, and food assistance programs across the state. And the broader debate — whether taxing the ultra-wealthy at the state level actually works, or just chases them to lower-tax states — is one that's playing out in state capitals across the country. California's vote this fall could set a national precedent either way.
Claude’s Scrutiny
The Fox News framing leans heavily on the "exodus" angle — but only 6 of California's estimated 214 billionaires actually left before the deadline, which makes "mass exodus" a real stretch and worth treating skeptically.
Key Takeaways
- California voters will decide in November on a one-time 5% tax on residents worth over $1 billion — a measure that could raise around $100 billion, mostly for healthcare.
- Gov. Newsom publicly opposes it, arguing billionaires will simply move to Texas or Florida, taking their ongoing tax contributions with them — and he's backed by the Legislative Analyst's Office on the revenue risk.
- The union driving the measure, SEIU-UHW, pressed forward despite Newsom's opposition and even rejected a behind-the-scenes compromise deal he offered.
- Opponents have serious financial firepower: Google co-founder Sergey Brin alone has donated $80 million to defeat the measure.
- Newsom responded by proposing a national billionaires' tax instead — a move widely read as early positioning for a 2028 presidential run.
