California Voters Reject Billionaire Tax After $100M Tech Blitz

California voters have rejected Proposition 40, a ballot measure that sought to impose a one-time 5% tax on the net worth of billionaires, according to NBC News projections ^[1]. The defeat marks a significant blow to progressives who championed the proposal as a solution to healthcare funding gaps, but it failed in the face of a well-funded campaign led by the state's tech elite.

The measure would have applied to residents with net worths exceeding $1 billion, with the option of a phased-in tax for those between $1 billion and $1.1 billion. It aimed to direct 90% of the revenue toward healthcare, according to CBS News ^[3]. However, the proposal became the most expensive tax-related contest in California history, with the "No" side outspending supporters by roughly 10 to 1, The Independent reported ^[2].

Silicon Valley was the primary force behind the opposition. Google co-founder Sergey Brin alone contributed more than $100 million to a political action committee working to defeat the measure, according to The Independent ^[2]. The coalition opposing Prop 40, known as Building a Better California, raised over $333 million, nearly a third of which came from Brin. Other notable opponents included Google co-founder Larry Page, PayPal co-founder Peter Thiel, and Stripe CEO Patrick Collison, CBS News noted ^[3].

The vote exposed deep fractures within the Democratic Party. While Senator Bernie Sanders and Representative Ro Khanna rallied for the measure, Governor Gavin Newsom opposed it, arguing it would drive wealthy taxpayers out of the state ^[1]. Major unions and organizations like the California Teachers Association and Planned Parenthood also joined the opposition, citing concerns over budget stability and the potential for a mass exodus of high earners.

Supporters of the tax, including Nvidia CEO Jensen Huang, argued that billionaires accumulate wealth through investments without paying income tax on those gains until they are realized ^[3]. Huang told CBS News he did not mind paying taxes, stating, "I don't mind paying taxes; the more you make, the more taxes you pay, so I'm okay with that".

Opponents successfully placed two dueling initiatives, Propositions 41 and 42, on the ballot, which would have effectively nullified Prop 40 if they passed with even one more vote, according to NBC News ^[1]. A Stanford University study indicated that billionaires who had already left the state, including Brin and Page, had removed about $540 billion from potential taxation, CBS News reported ^[3].
