Five percent of a mark is not five percent of cash.

The bill
Cable will call it a wealth tax. The measure is 25-0024A1 — a California initiative, not a bill moving through the Capitol.
On April 26, 2026, SEIU-UHW announced 1.6 million signatures. That is the campaign's figure. The qualification threshold is 874,641 valid signatures. As of April 26, certification was treated as pending, not done.
What the act actually does
- A one-time excise for 2026: 5% of net worth.
- Phase-in between $1 billion and $1.1 billion of net worth; a married couple is treated as one taxpayer.
- Worldwide assets count, including a spouse's.
- Residency is tested on January 1, 2026. Valuation is as of December 31, 2026.
- Payable in 5 installments, at 7.5% interest.
- Real property is excluded. Roth-type retirement accounts are excluded only up to $10 million.
Valuation rules: public holdings at market. Private holdings at GAAP book value plus 7.5 times average book profits, unless an appraisal is used. No valuation discount below pro-rata value.
Revenue split: 90% to health care, 10% to education and food assistance.
What the analysts say
The Legislative Analyst's Office and Department of Finance estimate temporary revenue in the tens of billions — and a likely ongoing personal income tax drop of hundreds of millions or more per year, as affected taxpayers respond. The LAO separately notes the top 1% pay roughly half of California's personal income tax, a volatile base.
Five percent of a mark is not five percent of cash
The Forbes marks from that date — Musk around $839 billion with roughly 21% liquid; Zuckerberg $224 billion with roughly 3% liquid — are snapshots from that date, not re-pulled here.
The method point stands regardless of the snapshot: a mark is not a clearing price. A 5% levy on marked net worth must be paid in cash, and the cash share of these fortunes is small. Selling to raise it moves the mark.
One correction the record requires: do not say CalPERS holds a $556 billion Magnificent-7 sleeve. The PERF's roughly $556.3 billion is total assets under management as of June 30, 2025, per the trust-level review — not a tech position.
The politics
Newsom opposed prior wealth-tax bills in the Capitol. An initiative removes the veto from the equation. The "three" prior bills cited then was not independently counted here.
What happened later
On June 17, 2026, the Secretary of State deemed the measure eligible for the November 3, 2026 ballot (PR26-85; tracking number 2001), with a projected 962,106 valid signatures against the 874,641 threshold.
The legal category
Comptroller v. Wynne, 575 U.S. 542 (2015), is the category to watch: state taxation reaching beyond its borders. The act anticipates the fight — 100% apportionment to California on a one-day residency snapshot, an alternative-apportionment relief valve, and a credit for net-wealth taxes paid elsewhere. A facial validation action in Sacramento carries a 60-day clock.
What remains unresolved
- The campaign's 1.6 million signature figure versus the later official count.
- How the one-day residency snapshot and worldwide reach survive a Wynne-category challenge.
- Whether the LAO/DOF revenue and outmigration estimates hold.
