California billionaire wealth tax on ballot, split
Entities: Proposition 40 · Bernie Sanders · California · Mark Zuckerberg · California Democratic Party
Overview
Proposition 40, a one‑time 5 % wealth tax on California residents whose net worth is at least $1 billion, was certified on June 26 2026 for the Nov 3 2026 ballot. The measure would apply to roughly 200‑250 of the state’s richest individuals and trusts, directing about 90 % of projected revenue to Medi‑Cal and the remaining 10 % to K‑12 education, food‑security and related programs. Support is organised by the Service Employees International Union‑United Healthcare Workers West (SEIU‑UHW), with endorsements from labor unions, progressive Democrats, economist Emmanuel Saez and philanthropist Tom Steyer. Proponents estimate the tax could raise $89 billion–$128 billion over five years, with some projections exceeding $100 billion. Opposition is anchored by a billionaire‑funded coalition called Building A Better California. Tech billionaire Sergey Brin has contributed roughly $82 million of an estimated $87 million pledged for a statewide TV campaign, joined by donors such as John Doerr and Michael Moritz. The group also introduced counter‑initiatives 41 (program audits) and 42 (ban on new personal‑asset taxes). A union watchdog, the Center for Union Facts, disclosed that SEIU‑UHW has spent about $1.34 million of member dues on luxury resort travel for staff, including trips to the Langham Huntington, Kona Kai Resort and the Caribe Hilton. The watchdog said the complex LM‑2 filings make it hard for members to track such spending, prompting accusations of hypocrisy. Within the Democratic Party, the proposal has deepened internal divisions. Labor groups such as the State Council of Laborers and United Domestic Workers have opposed Proposition 40, citing fiscal‑risk concerns, while progressive factions and several party leaders continue to back it as a source of funding for Medi‑Cal and other social programs.
Coverage disagrees
Sources make claims that cannot both be true. CLSTR reports the disagreement; it does not decide who is right.

"Mark Zuckerberg has moved to Florida, so he would not pay the California wealth tax if it passes." (Bernie Sanders tweet article)
vs
"If passed, Mark Zuckerberg would owe $10.5 billion in taxes, leaving him with $200 billion in assets." (Bernie Sanders tweet article)
One claim says Zuckerberg would not pay the California wealth tax because he moved to Florida, while the other claims he would owe $10.5 billion if the tax passes; both cannot be true simultaneously.
