California Governor Proposes Tax on Super Wealthy and AI Ownership

California governor proposes national ‘billionaires tax’ and federal stake in AI companies

California Governor Gavin Newsom called Tuesday for a national tax on the wealthiest Americans and proposed that the federal government take equity stakes in artificial intelligence companies, marking a direct challenge to both state and national tax policies. The proposals, announced during a press conference in Sacramento, come as the state faces a budget shortfall while federal lawmakers remain divided over tax increases.

Newsom’s plan would impose a progressive tax on individuals with net worth exceeding $50 million, with rates rising to 4% for those worth over $1 billion. He also suggested that the U.S. government acquire minority stakes in AI firms—similar to models used in other countries—to fund public research and development while mitigating risks associated with rapid technological advancement.

“This isn’t just about raising revenue—it’s about redefining how we invest in the future,” Newsom said, according to a transcript of his remarks. “We can’t let a handful of ultra-wealthy individuals hoard resources while the rest of the country struggles with infrastructure, education, and innovation gaps.”

The governor’s push for a federal tax contrasts sharply with California’s own stalled efforts to implement a similar measure. In April, Newsom vetoed a state-level billionaires tax proposal, citing concerns over legal challenges and potential economic consequences. A spokesperson for the governor’s office confirmed that the veto was based on “practical and constitutional hurdles,” though Newsom’s new federal proposal suggests a shift in strategy.

Why the federal push?
Newsom’s proposal aligns with growing bipartisan interest in targeting wealth inequality, though details remain sparse. The White House has not yet responded, and congressional Republicans have historically opposed new taxes. However, a June poll by the Pew Research Center found that 68% of Americans support higher taxes on the ultra-rich, potentially creating political momentum.

The AI stake proposal is more novel. Newsom cited examples from South Korea and the European Union, where governments have taken equity in tech firms to fund public research. “We’re not talking about nationalizing companies, but about ensuring that breakthroughs benefit all Americans, not just a few shareholders,” he said.

How would it work?
Under Newsom’s outline, the federal government would purchase shares in AI companies—likely through a new public-private partnership—with proceeds directed toward education, healthcare, and infrastructure. Critics, including tech lobby groups, argue that such interventions could stifle innovation. The California Tech Council, a trade association, called the idea “unprecedented and risky” in a statement Tuesday.

What happens next?
Newsom’s proposals lack legislative backing. The governor’s office did not provide a timeline for formalizing the plans, but aides indicated they would be included in upcoming budget discussions. White House press secretary Karine Jean-Pierre declined to comment on the specifics, stating only that the administration is “monitoring developments.”

For now, the proposals remain theoretical. But with California’s economy—home to Silicon Valley—at the forefront of AI and wealth disparities, Newsom’s ideas could reshape national debates on taxation and technology governance.
