California's Billionaire Tax: The Most Expensive Mistake in History — And What It Means for Orange County Real Estate

The Most Expensive Mistake in History

Take ANY billionaire you know. Now tell them you’re THINKING about a 5% wealth tax — just on them. Now tell them to stay put while you work with lobbies and special interests to get it on the ballot, get it overwhelmingly approved by your blue-state voters — then find those billionaires when it’s time to pay up.

Where did they go?

If you said Florida, Texas, and Nevada — you’d be correct.

Mark Zuckerberg, Larry Page, Sergey Brin, Peter Thiel, Larry Ellison, and former Uber CEO Travis Kalanick have all made multi-million-dollar real estate purchases in tax-friendly states. Steven Spielberg moved to New York on New Year’s Day. These aren’t vacation homes — they are fleeing the Golden State. And they happened within weeks of the proposed 2026 Billionaire Tax Act being announced.

This is an insane proposal. Take anyone with resources and options, tell them you intend to limit their options, and watch what they do.

We see this with rent control. Fun fact: there’s not a single market in the country where rent control led to slower rental growth compared to surrounding areas — not one. Limits on free markets, unreasonable tax policy with no clear upside, and out-of-control legislatures will eventually produce the same result in California.

What’s Actually Happening With the Billionaire Tax

The 2026 Billionaire Tax Act (Initiative 25-0024), backed by the SEIU-United Healthcare Workers West, proposes a one-time 5% tax on the net worth of any California resident worth $1 billion or more. The catch? It would apply retroactively to anyone who was a California resident as of January 1, 2026 — a date that had already passed by the time most people heard about it. Good luck with that CA…

The initiative needs roughly 875,000 valid signatures by June 2026 to land on the November ballot. If passed, proponents project $100 billion in revenue for healthcare, education, and food assistance.

But here’s what the proponents won’t tell you: a Hoover Institution study out of Stanford found that the tax would actually cost California an estimated $25 billion once lost income tax revenue from departing billionaires is factored in. Six billionaires publicly left before the January 1 cutoff — and they took an estimated $27 billion in potential tax revenue with them. More are expected to follow.

The bill, if passed, will lose the state money and be mired in legal battles funded by the very individuals it targets. Constitutional challenges are already being lined up on due process, equal protection, and bill of attainder grounds. Most of the approximately 200 billionaires in the state will simply leave. Meanwhile, Californians who stay will be impacted by fewer job opportunities, less statewide funding, and fewer large corporations providing futures for their families.

It’s a bad bill for obvious reasons — but it was also an insane suggestion in the first place.

Why This Matters for Orange County

According to the Orange County Business Journal’s 2025 list, there are 43 billionaires who either reside in, have homes in, or run major businesses in Orange County. That’s up to 20% of California’s entire billionaire population concentrated right here. Twelve of those are “weekend Californians” who maintain homes here but don’t claim OC as a primary residence. We’ll have to see how the eventual initiative is drafted to understand how it tries to sink its teeth into those folks.

Many of these billionaires are also massive job creators in OC — think Broadcom, Anduril, the Irvine Company. They can and will be job creators in other markets if they get pushed out. The wealth tax will be disproportionately bad for Orange County, which claims residence of more than 20% of the state’s total billionaires.

The Governor’s Race Adds Uncertainty

Pile on housing shortages, historically moderate mortgage rates, and a wide-open governor’s race — Governor Newsom is term-limited and can’t run again, leaving a crowded field of over two dozen candidates with no clear frontrunner — and you’ve got a recipe for uncertainty. With Newsom clearly eyeing a 2028 presidential run, the question is whether California’s policy direction becomes a campaign prop rather than sound governance for the people who actually live here.

The governor’s race will be a consequential one, no matter what. It leaves home buyers and sellers in Orange County with real questions about their future in the Golden State.

What Should Orange County Homeowners Do?

If you’re an equity-rich homeowner in Anaheim Hills, Yorba Linda, Tustin, or anywhere in North Orange County, the uncertainty around this tax and the upcoming governor’s race is worth paying attention to — not to panic, but to plan.

Whether you’re thinking about selling, buying, or just want to understand how these shifts could affect your home’s value and your neighborhood, that’s a conversation worth having with someone who knows this market.
