Billionaire Brawl Explodes In California

California’s new billionaire tax measure promises a $100 billion rescue for healthcare but may instead expose how deeply both parties have let elites write the rules while ordinary people pick up the tab.

Story Snapshot

A one-time 5% tax on about 200 California billionaires has officially made the November ballot.
Backers say it will raise $100 billion for healthcare, education, and food aid; critics say much less will show up.
The fight pits unions and populist anger against billionaires, corporate donors, and Governor Gavin Newsom.
Both sides warn of serious risks, underscoring a system that seems unable to fund basic care without crisis taxes.

What the Billionaire Tax Would Actually Do

California voters will decide in November whether to approve the “2026 Billionaire Tax Act,” a one-time 5% tax on the net worth of people with at least $1 billion who lived in the state on January 1, 2026.^[10] The tax base is worldwide wealth as of late 2026, and payments can be spread over five years. Real estate people live in directly, pensions, and retirement accounts are excluded.^[17] About 200 billionaires would be affected.^[6] Supporters estimate the tax will raise about $100 billion between 2027 and 2031.^[5]

Almost all the new money would be locked away from the state’s normal budget fights. The initiative creates a special fund where 90% must go to healthcare and 10% to education and food assistance.^[10] Lawmakers could spend up to roughly $25 billion per year from that fund on programs like Medi-Cal and CalFresh, which serve lower- and middle-income residents.^[6] This structure appeals to voters tired of “bait-and-switch” taxes that vanish into the general fund, but it also limits how flexible the state can be in a future downturn.

Supporters: A Lifeline After Federal Cuts, Paid by the Very Rich

The measure is driven by Service Employees International Union–United Healthcare Workers West, the state’s largest healthcare workers union, which has already poured tens of millions into the campaign.^[6] Union leaders argue that deep federal cuts to Medicaid and other health programs, signed by President Trump in his “One Big Beautiful Bill,” created about a $100 billion funding gap that will otherwise mean higher premiums, lost coverage, and hospital closures.^[6]^[7] For many voters, that looks like Washington broke the system and billionaires are being asked to patch the hole.

An expert report led by economists Emmanuel Saez and Gabriel Zucman backs the $100 billion figure.^[5] They base it on about $2.2 trillion in wealth held by the top 200 California taxpayers and assume only 10% is lost to tax avoidance and evasion.^[3] They stress that this is a one-time tax on extreme fortunes, not a new burden on homes or small businesses, and say it is administratively workable because it hits a tiny number of taxpayers.^[5] Supporters also point to early polls showing a small majority of voters in favor, at least before heavy advertising starts.^[6] For many on both left and right who feel the rich never pay their share, this looks like a long-awaited test of whether elites can ever be made to contribute more.

Opponents: Flight Risk, Legal Fights, and a Temporary Fix

Opposition is just as intense and far better funded. Governor Gavin Newsom, many major unions, Planned Parenthood affiliates, and the State Building and Construction Trades Council have come out against the tax, joining tech billionaires and other wealthy donors.^[9]^[16] A Hoover Institution study argues the $100 billion estimate rests on unrealistic behavior assumptions and says actual collections could be closer to $40 billion once migration and avoidance are included.^[1]^[21] That gap matters because working families are tired of big promises that later get walked back.

The nonpartisan Legislative Analyst’s Office warns that while the tax would likely bring in “tens of billions” one time, it could also reduce regular income tax revenue by “hundreds of millions of dollars or more per year” if enough billionaires leave and take their future income with them.^[17] Real estate agents and financial advisers already report ultra-wealthy clients selling homes and moving to low-tax states, though those claims are mostly anecdotal and not yet backed by a detailed California-specific study.^[10]^[21] Critics also note that the tax hits hard-to-value assets like private company stock and art, almost guaranteeing costly legal battles and delays.^[5] Even some progressives argue that a one-time levy on billionaires is more of a political message than a lasting fix for a structurally underfunded healthcare system.^[8]

Deeper Divide: Voters Versus a System That Keeps Failing Them

This fight is not just about billionaires. It reflects a bigger pattern that frustrates both conservatives and liberals. On one side, people see a political class that let federal healthcare funding get cut while protecting defense contractors, Wall Street, and big corporations. On the other, they see state leaders who say there is “no money” for hospitals and poor families unless a rare group of billionaires can be tapped with a crisis tax. That story feeds the sense that the system never plans ahead and always turns to emergency measures.

Wealth taxes often come with bold promises that later shrink once real-world behavior kicks in.^[21] Supporters of this measure admit it is temporary but argue that a one-time shot in the arm is better than letting clinics close and jobs vanish.^[7] Opponents warn it will scare off investment, shrink the tax base, and push California deeper into reliance on a small group of mobile ultra-rich families. Both sides, in different ways, are pointing to the same uncomfortable truth: after years of partisan fights and elite deal-making, the richest state in the country is asking a few hundred people to decide whether millions can keep basic healthcare. That is the kind of upside-down math that makes many Americans, right and left, feel the game is rigged.
