What happened
California voters will decide Proposition 40 on the Nov. 3 ballot, a measure that would impose a one-time tax equal to 5% of net worth on billionaires who were California residents on Jan. 1, 2026. The tax would be due in 2027, with payments optionally spread over five years at additional cost; real estate, pensions, and retirement accounts would generally be excluded. The California Democratic Party has endorsed the measure; Gov. Gavin Newsom has expressed opposition. The state's nonpartisan Legislative Analyst's Office estimated the tax could temporarily raise tens of billions of dollars over several years, while behavioral responses, including some billionaires leaving, could reduce annual income-tax revenue by less than $1 billion. Entrepreneur Eric Schiffer, chairman of family office Patriarch, publicly warned that passage could prompt successful business leaders to leave California.

2 of 2 articles cite a named source for the story. It was on the record from the first report.
What these terms mean and how they're counted
- On the record · names a source 2 of 2
- On the record means the article cites a source by name for the story's main claim: a person, or an institution speaking officially, such as a company statement or a named agency's spokesperson. The opposite is an unnamed source. The count is how many of the counted articles cite at least one such source; the names are everyone named across them, each once however the articles spell it. Here: Eric Schiffer and Steve Hilton
- Primary evidence · cites a document or data 0 of 2
- Primary evidence means the article cites a record you could check yourself: a court filing or ruling, a dataset or report, a recording or transcript, an official statement or press release, market data. A quote is not a document. The count is how many articles cite one. Here: None cited.
- Credits another outlet 0 of 2
- The article says the story comes from another outlet's reporting (“first reported by Reuters”). Those articles relay the story; they are not independent confirmation. Here: Each article presents its own reporting.
- Unnamed sources 0 of 2
- The main claim is attributed to people who are not identified: “people familiar with the matter”, “officials said”. The count is how many articles do this.
- How it developed
- When the first report landed and whether it named anyone; when the first named source and the first document appeared. Here: First report Sep 19, 08:16 UTC by Fox Business, naming its source.

Omitted — what each side leaves out
Unpacked
Left-leaning coverage has not reported this fight. Right-leaning coverage reports that entrepreneur Eric Schiffer warned a California ballot measure could drive billionaire business leaders out of the state. The warning appears in Fox Business as a "giant sucking sound" of exits if the one-time levy passes. The tax would equal 5% of net worth for billionaires who were residents on a fixed date. Anyone reading only left-leaning outlets would not know the measure is on the November ballot. They would also miss that the state's nonpartisan fiscal office expects some of those residents to leave.
Among right-leaning outlets the emphasis splits. Newsom's opposition is reported by Fox Business. That outlet also prints an estimate of tens of billions in temporary revenue. Those figures do not appear in National Review, which instead casts the proponents as "class warriors and labor bullies."
How many California residents would actually owe the tax?
Bottom line
A reader of left-leaning news would not know California is voting on a one-time 5% billionaire tax that Fox Business says could send entrepreneurs packing.
The receipts — 5 facts one side's coverage lacks
- Proposition 40 would impose a one-time 5% tax on the net worth of billionaires who were California residents on January 1, 2026
- The Legislative Analyst's Office estimates behavioral responses could reduce state income tax revenue by less than $1 billion per year
- Real estate, pensions, and retirement accounts generally would be excluded from the tax
- The measure has been endorsed by the California Democratic Party
- The tax would be due in 2027, with payments spreadable over five years at additional cost
The Right View
Fox Business and the New York Post both led with California entrepreneur Eric Schiffer warning that Proposition 40 could produce a "giant sucking sound" of entrepreneurs exiting the state, arguing they would not remain after being taxed on already-taxed wealth and would feel unappreciated and "under attack." Those outlets reported his claims that working Californians could face fewer jobs and opportunities, that similar taxes could later target people worth hundreds of millions, and that he himself would leave if the policy reached that range. They also cited Mark Cuban's point that founders can be cash-poor and stock-rich, the Legislative Analyst's Office revenue estimates, Newsom's opposition, Republican gubernatorial candidate Steve Hilton's economic warnings, and Rep. Ro Khanna's argument that the levy would help preserve health care for working-class Californians. National Review framed the measure as the work of class warriors and labor interests seeking to get rid of billionaires.
Our Take (balanced)
The ballot measure itself is substantive: it has a defined tax rate, residency date, payment schedule, named backers and opponents, and a published Legislative Analyst's Office estimate. Schiffer's mass-exodus warning is one businessman's prediction, not corroborated here by named billionaires announcing they will leave or by relocation records; the "giant sucking sound," workplace-opportunity losses, and slippery-slope claims remain alleged. What is established is the LAO's own language that "some billionaires" may leave and its estimate of under $1 billion a year in lost income-tax revenue against tens of billions in temporary wealth-tax receipts—those are the office's figures, not proof of a broad flight. No left-leaning outlet has reported this. Watch for the official Proposition 40 text and full LAO report, any named high-net-worth residency changes or corporate moves, campaign-finance and endorsement filings, and on-the-record responses from Newsom, Khanna, and affected firms before the Nov. 3 vote.
