The total wealth that has left California is now $1 trillion.
California had $2 trillion of billionaire wealth just a few weeks ago. Now, 50% of that wealth has left – taking their income tax revenue, sales tax revenue, real estate tax revenue and all their staffs (and their salaries and income taxes) with them.
In other words, by starting this ill conceived attempt at an asset tax, the California budget deficit will explode. And we still don’t know if the tax will even make the ballot. If the measures passes, it could be held up with lawsuit challenges.
California billionaires were reliable tax payers – 13.3% every year.
Unless this ballot initiative is pulled, we will not stop the billionaire exodus. With no rich people left in California, the middle class will have to foot the bill.
Unfortunate update as of today:
More calls from friends. The total wealth that has left California is now $1T.

The “2026 Billionaire Tax Act” is a voter initiative backed by the Service Employees International Union–United Healthcare Workers West (SEIU-UHW) that aims to appear on California’s November 2026 ballot, provided it gathers around 875,000 signatures. It would impose a one-time 5% excise tax on the net worth (including all forms of personal property and wealth, tangible or intangible) of applicable individuals and trusts exceeding $1 billion.
Key details
It targets California residents (full- or part-year) as of January 1, 2026, with retroactive effect if passed. This includes those who were residents as far back as January 1, 2025, in some cases, to prevent last-minute exits.
Exemptions are directly held real estate, pensions, and retirement accounts are excluded. However, real estate owned through businesses would be taxable.
Payment Structure. Due in 2027, but taxpayers can opt to spread payments over five years (with a small deferral fee/interest charge).
Revenue Projection
Expected to raise approximately $100 billion over five years (or about $20 billion annually) from roughly 200 affected billionaires, primarily to offset federal cuts to healthcare (Medi-Cal), education, and food assistance programs. For example, someone with $20 billion in taxable net worth would owe $1 billion, while higher-net-worth individuals like Larry Page (estimated $258 billion) could face over $12 billion.
Broader Implications
Critics, including Palihapitiya, describe it as an “asset seizure” and warn that the fine print could enable future expansions to non-billionaires (e.g., taxing cars, homes, or jewelry). Supporters frame it as a fair, one-time contribution from those who have benefited most from California’s economy to address inequality and budget shortfalls, estimated at $19 billion annually for Medi-Cal alone under potential federal changes.
Legal and Economic Context
California’s Legislative Analyst’s Office estimates it could generate tens of billions in one-time revenue but lead to long-term annual losses of hundreds of millions in state income taxes if billionaires relocate.
The initiative is opposed by Governor Gavin Newsom and many tech leaders, who argue it could be blocked via lawsuit under provisions allowing the state to halt measures that impede governance
California’s top marginal rate is 13.3% on ordinary income and capital gains (treated as income). Billionaires often realize massive gains from stock sales, IPOs, or venture exits. If the $1 trillion in exited wealth previously generated even a conservative 5% annual return (e.g., via investments), that’s $50 billion in potential income/cap gains subject to tax—yielding about $6.65 billion annually in state revenue at the top rate. More realistically, with variable realizations (tech founders cashing out stakes), losses could exceed $10-20 billion per year statewide from reduced high-earner contributions.
Billionaires employ large staffs (household, security, administrative) and fund ventures that create jobs. A single billionaire’s operations might support hundreds of roles with salaries totaling tens of millions annually. At scale, the $1 trillion exodus could displace thousands of high-paying jobs (in tech, VC firms), leading to $5-10 billion in lost annual wage income statewide.
