California's Billionaire Tax, Two Weeks Out: The Money, the Polls, and the Rival Measure
The frozen corpus, as of Oct. 19, records three dated opposition fundraising totals from three outlets, polls from three pollsters that differ by date and house, a rival proposition whose effect every describing outlet keeps conditional, and one frame only the New York Post supplies. Each figure below carries its outlet and its date.
- Opposition fundraising is reported at more than $300 million (AP, Oct. 9), about $318 million (Bloomberg, Oct. 13), and above $340 million (Guardian, Oct. 16).
- Sergey Brin is the largest donor at at least $102 million, nearly a third of the $300 million total AP reports.
- Polls split: 46% for and 43% against (Politico, Oct. 19); 50% against and 35% for (Manhattan Institute, Sept. 24-Oct. 1).
- Proposition 40 is nullified only if Proposition 42 or 41 draws more votes; no vote has been held.

TL;DR
Two weeks before the Nov. 3 vote, California's Proposition 40 — a one-time 5% tax on the net worth of the state's roughly 200 billionaires — is the subject of conflicting polls and heavy opposition spending. Opponents have reported war chests of more than $300 million, far exceeding the "yes" side's $32 million. A rival measure, Proposition 42, could cancel Proposition 40 if it receives more votes. The state of the race remains unresolved: the surveys differ by pollster and field date.
The charge
New York Post: "A billionaires’ tax pushed by radical leftists such as Sen. Bernie Sanders on California’s ballot next month — and with “Squad” Rep. Alexandria Ocasio-Cortez ready to take the idea national — a furious, freak alliance of enemies has formed to try to kill it."
"Radical leftists" appears in the Post's lead and in no other outlet in the record. No other outlet uses this framing.
The audit
The opposition's fundraising is reported three times, on three dates, at three sizes. AP reported on Oct. 9: "They have raised more than $300 million in opposition to the measure, with nearly a third of that coming solely from Google co-founder Sergey Brin. That is roughly 10 times the amount raised by the “yes” side, which includes some labor unions, California Rep. Ro Khanna and Vermont Sen. Bernie Sanders."
Bloomberg's committee total, disclosed in filings, was about $318 million on Oct. 13. Bloomberg: "Groups backed by some of the world’s richest people are pouring cash into a final push against California’s proposed wealth tax, escalating what’s already one of the country’s most expensive battles of this election cycle."
The Guardian's Oct. 16 standfirst put the total above $340m. The Guardian (US): "The biggest donor, by far, is the Google co-founder Sergey Brin, who has contributed at least $102m to fight the tax, according to campaign finance filings." The Guardian also reported: "During the first 19 days of September, according to the most recent campaign filings, the opposition campaign plowed through at least $21.2m to fight the billionaire tax – surpassing $1m per day."
The Guardian and Bloomberg rest on campaign-finance disclosures; AP's $300 million carries no filings attribution in its record. On the "yes" side, Forbes reported: "$32 million. That’s how much the sponsor of Prop. 40, California’s largest health care workers’ union, has raised to promote the tax. That’s less than 10% of the opposition’s war chest." Forbes attributes the opposition total to The Guardian.
On revenue, Reuters keeps both estimates attached to their claimants: "Backers say California's measure would generate $100 billion for healthcare, food assistance and education. But skeptics peg the revenue estimate at closer to $40 billion".
The defense
The opposition's economic case, in its own words, from Al Jazeera on Feb. 18: "“This isn’t a tax on billionaires; it’s a tax on California’s economy,” said Patrick Kallerman, vice president at the Bay Area Council, a San Francisco-based business association."
Gov. Gavin Newsom has endorsed the countermeasure. The Hill: "On Friday, Newsom endorsed Proposition 42, which would prohibit retroactive taxes imposed by Proposition 40, known as the Billionaire Tax Act, for any billionaire who lived in California on Jan. 1, 2026, CalMatters reported." Per Newsweek, Proposition 40 is nullified if Proposition 42 — or Proposition 41 — receives more votes, and Prop 40 carries a mirror provision of its own. Nothing has been nullified; the propositions have not been voted on. Newsweek: "Propositions 41 and 42 are sponsored by Building a Better California, a group established by Google co-founder Sergey Brin and former Google CEO Eric Schmidt."
A supporter of the measure, quoted by Fox Business: "“It’s beyond disappointing; at this point, it’s disqualifying for anyone with ambitions for higher office as a Democrat, or a Republican, for that matter, to be fighting to keep billionaires from being taxed while kids don’t have health insurance and the cost of living goes sky-high.”"
The verdict
The polls disagree by pollster and field date. Politico, published Oct. 19: "Likely voters are essentially where they were a month ago, the survey found, with 46% in favor of Proposition 40 and 43% opposed". USA TODAY, reporting a Manhattan Institute survey of 1,000 likely voters conducted Sept. 24 to Oct. 1: "A Manhattan Institute poll found that likely voters oppose the measure by 15 points (50% to 35%), while 15% remain undecided." The Washington Examiner carried an earlier September Berkeley–Politico figure of 45% for, 42% against, 12% undecided. The Financial Times, in an Oct. 19 column, assessed: "Prediction markets say no, although polls show voters are slightly in favour."
The record supports a dated money gap that grows with each dated report, polls that differ by pollster and date, a countermeasure that does nothing unless it outpolls the measure it targets, and one outlet's framing that the others decline. It does not support a true number for the war chest, a state of the race, or an outcome on Nov. 3.
The state of the race on Proposition 40 is unresolved; the surveys differ by pollster and date and are not averaged.
CBS News and NPR both file the mechanics of Proposition 40: a one-time, 5% state tax on the net worth of California's billionaires, on the Nov. 3 ballot. This desk wrote up the supporters' economic case in a September piece; the newest records in the corpus — The Guardian and Forbes dated Oct. 16, Politico dated Oct. 19 — carry the final-stretch material: the money, the newest polls, and the countermeasure. Four tracks, reported as they sit.
The money first. The opposition's war chest is described three times, on three dates, at three sizes.
They have raised more than $300 million in opposition to the measure, with nearly a third of that coming solely from Google co-founder Sergey Brin. That is roughly 10 times the amount raised by the “yes” side, which includes some labor unions, California Rep. Ro Khanna and Vermont Sen. Bernie Sanders.
Groups backed by some of the world’s richest people are pouring cash into a final push against California’s proposed wealth tax, escalating what’s already one of the country’s most expensive battles of this election cycle.
The biggest donor, by far, is the Google co-founder Sergey Brin, who has contributed at least $102m to fight the tax, according to campaign finance filings.
The Guardian's Oct. 16 standfirst puts the total above $340m; AP's figure is Oct. 9; Bloomberg's committee total of about $318 million, disclosed in filings, is Oct. 13. Three outlets, three dates, three sizes, in ascending order on both axes; the calendar and the total move together. The Guardian and Bloomberg rest on campaign-finance disclosures; AP's $300 million carries no filings attribution in its record. The Guardian also logs the pace: "During the first 19 days of September, according to the most recent campaign filings, the opposition campaign plowed through at least $21.2m to fight the billionaire tax – surpassing $1m per day." Its headline says the same thing in longer words. The other side of the ledger:
$32 million. That’s how much the sponsor of Prop. 40, California’s largest health care workers’ union, has raised to promote the tax. That’s less than 10% of the opposition’s war chest.
Forbes attributes the opposition total to The Guardian; "less than 10%" is Forbes's comparison against that figure, not against AP's or Bloomberg's.
The polls. The newest survey was published today. It does not agree with the others, and it does not have to — different pollsters, different field dates.
Likely voters are essentially where they were a month ago, the survey found, with 46% in favor of Proposition 40 and 43% opposed
A Manhattan Institute poll found that likely voters oppose the measure by 15 points (50% to 35%), while 15% remain undecided.
USA TODAY's survey of 1,000 likely voters ran Sept. 24 to Oct. 1. The Washington Examiner, filing the Democratic split, carries the earlier Berkeley figure — 45% for, 42% against, 12% undecided — an earlier Berkeley–Politico poll from September. The Financial Times, in an Oct. 19 column, reads the same landscape both ways at once: "Prediction markets say no, although polls show voters are slightly in favour."
The countermeasure. The third track is conditional, and every outlet that describes it keeps the conditional intact.
On Friday, Newsom endorsed Proposition 42, which would prohibit retroactive taxes imposed by Proposition 40, known as the Billionaire Tax Act, for any billionaire who lived in California on Jan. 1, 2026, CalMatters reported.
The mechanism, per Newsweek's account of the ballot rules: Proposition 40 is nullified if Proposition 42 — or Proposition 41 — receives more votes, and Prop 40 carries a mirror provision of its own. Nothing has been nullified; the propositions have not been voted on. Both rivals are sponsored by Building a Better California, per Newsweek below.
The frame. One outlet in the corpus supplies the language the rest do not use.
A billionaires’ tax pushed by radical leftists such as Sen. Bernie Sanders on California’s ballot next month — and with “Squad” Rep. Alexandria Ocasio-Cortez ready to take the idea national — a furious, freak alliance of enemies has formed to try to kill it.
"Radical leftists" appears in the Post's lead and nowhere else in the corpus. The Post's language is the Post's; the record reports it as the Post's characterization. The remaining files, filed one per newsroom:
Backers say California's measure would generate $100 billion for healthcare, food assistance and education. But skeptics peg the revenue estimate at closer to $40 billion
So, to bridge the gap, Regan and the union led a petition drive to put on the November ballot a one-time, 5% state tax on the net worth of California's 200 or so billionaires, known as Proposition 40.
It would impose a one-time 5% tax on people in the state with over a billion dollars of wealth, like stocks, bonds and artwork.
Propositions 41 and 42 are sponsored by Building a Better California, a group established by Google co-founder Sergey Brin and former Google CEO Eric Schmidt.
Gov. Gavin Newsom (D-CA) is sparring with other Democrats over California’s proposed billionaire tax, publicly endorsing a ballot measure that would cancel out the proposed tax on the state’s wealthiest residents.
Mr. Newsom announced his support for Proposition 42 on Friday. The measure, funded by Google co-founder Sergey Brin, would cancel out Proposition 40, a one-time 5% tax on the assets of billionaires who lived in California as of Jan. 1, 2026, CalMatters reported.
“It’s beyond disappointing; at this point, it’s disqualifying for anyone with ambitions for higher office as a Democrat, or a Republican, for that matter, to be fighting to keep billionaires from being taxed while kids don’t have health insurance and the cost of living goes sky-high.”
Prediction markets say no, although polls show voters are slightly in favour.
The ballot measure, Proposition 40, would impose a one-time, 5% tax on billionaires living in the state to help backfill federal funding cuts to healthcare for low-income people. The proposal has caused a rift within the Democratic Party and among labor unions that are typically aligned.
“This isn’t a tax on billionaires; it’s a tax on California’s economy,” said Patrick Kallerman, vice president at the Bay Area Council, a San Francisco-based business association.
Yet in California, the richest state, a wealth tax is making steady progress towards becoming law.
The two oldest files predate the final stretch and are labeled; the newest file is today's. What the record supports: a dated money gap that grows with each dated report, polls that disagree by pollster and date, a countermeasure that does nothing unless it outpolls the measure it targets, and one outlet's framing the others decline. What it does not support is a true number for the war chest, a state of the race, or an outcome on Nov. 3.
