California 2026 Billionaire Tax Act: Tech Leaders Threaten Exodus Over Wealth Tax

Longtime allies are sharpening their knives. Rep. Ro Khanna (D-Calif.), once a darling of Silicon Valley, is facing a fierce backlash from tech titans after embracing a controversial statewide wealth tax. According to CNBC, top venture capitalists and founders aren't just expressing anger; they're threatening to pull funding and back primary challengers against the congressman.

Inside the California 2026 Billionaire Tax Act

The proposed ballot measure, known as the 2026 Billionaire Tax Act, aims to shore up California's healthcare budget shortfall. It seeks to levy a one-time 5% tax on the total assets of individuals worth over $1 billion. If approved by voters in November 2026, the tax would be retroactive to January 1, 2026.

The flashpoint for the tech community is the taxation of unrealized gains. Startup founders who are wealthy on paper—due to the value of their private stock—would be forced to pay massive tax bills even if their assets are illiquid. Reddit co-founder Alexis Ohanian voiced his concern on X, stating that while society must adapt to the wealth gap, "the answer is definitely not taxing unrealized gains."

Political Fallout and the Silicon Valley Exodus

The rift has turned personal. Martin Casado of Andreessen Horowitz posted that Khanna has done a "speed run alienating every moderate" he knows. Garry Tan, CEO of Y Combinator, openly called for a primary challenge. In response, Khanna remained defiant, echoing FDR's sarcasm regarding "economic royalists" who threaten to leave: "I will miss them very much."

This internal Democratic struggle comes as tech leaders increasingly flirt with the GOP. With Gov. Gavin Newsom opposing the state-level tax as "impractical," the debate highlights a growing divide between the party's progressive wing and the capital that fuels the innovation economy. Vinod Khosla warned that advisors will tell every successful enterprise to relocate if the measure gains traction.
