The California wealth tax is a window into billionaires' risk tolerance

• A proposed wealth tax in California evoked split responses from the state's billionaires.
• Google's Larry Page moved businesses out of California, while Nvidia's Jensen Huang is "perfectly fine" with the tax.
• Responses can reveal how the wealthy balance financial risk in the face of uncertainty.

It's a classic fight-or-flight response — with a billionaire's twist.

A proposed wealth tax in California prompted the state's resident billionaires to consider whether they wanted to continue their residency if the one-time 5% tax is approved.

Their reactions, said CFP professional Don Hilario, who works with financial planning clients in California, boil down to risk tolerance.

The tax, as proposed, would only apply to assets in the state during the 2026 tax year. Google cofounders Larry Page and Sergey Brin moved assets out of California ahead of the January 1, 2026, deadline to avoid facing the tax, Business Insider first reported. Meanwhile, Nvidia's billionaire CEO Jensen Huang said he has "not even thought about it once."

"We chose to live in Silicon Valley, and whatever taxes they would like to apply, so be it," Huang told Bloomberg TV's Ed Ludlow. "I'm perfectly fine with it."

Hilario, whose financial planning clients include individuals in Big Tech, said that the lingering uncertainty of the tax can trigger a need for certainty and autonomy.

"People who want to have a greater sense of control will do the Larry Page route," he said, "versus people who have the temperament to endure will take Jensen's route."

Hilario described a hypothetical scenario in which individuals with high net worths are considering purchasing a home. In a period where the economy and interest rates are uncertain, do you want to put the lion's share of your expenses toward the home in the event that rates will be higher in the future, or do you hold out and continue accumulating your wealth in the event that economic conditions improve?

"That's the same type of emotions that exist with this tax bill because the fear of not taking any action is unsettling," Hilario said.

The proposal, put forth by the union SEIU-United Healthcare Workers West to offset potential budget cuts to healthcare and education, is far from being implemented — it would require 870,000 signatures to make it onto the November 2026 ballot.

The SEIU said in its proposal that the concentration of billionaire wealth in California makes the state "uniquely positioned to address both the well-documented crisis of wealth inequality in the United States and the emerging and interrelated crises the state faces" with the budget cuts.

In addition to Huang, Brin, and Page, other billionaires are voicing their opinions on the proposed wealth tax. LinkedIn's cofounder, Reid Hoffman, wrote in a post on X that the proposal has "massive flaws."

"Poorly designed taxes incentivize avoidance, capital flight, and distortions that ultimately raise less revenue," he said.

Alex Spiro, an attorney who has previously represented billionaires, wrote in a letter to California Gov. Gavin Newsom that his clients would "permanently relocate" if the tax were to become law. Hilario said that the significant uncertainty surrounding the proposal, including how assets will be valued and whether the tax would change over time, likely forced billionaires to decide how risk-averse they really are.

"I still think ultimately it's unclear. And I think when it's unclear, it'll make people, in this case, investors, be more cautious and defensive," Hilario said. "And then a big part of it is, how do we respond emotionally? I think whether you're taking early action or enduring, you do want to gather information and avoid making a decision that would ultimately be irreversible."
