Quick Summary

California voters rejected Proposition 40, which aimed to impose a one-time 5% wealth tax on billionaires in the state with net worth over $1 billion as of January 1, 2026. The measure was intended to fund healthcare programs and other social services but faced strong opposition from tech industry leaders like Sergey Brin, who donated at least $132 million against it, making the campaign one of the most expensive in state history at nearly $425 million total. This outcome could stall similar efforts nationwide to tax the ultra-wealthy for public funding.

Story summary

On November 3, 2026, California voters rejected Proposition 40, which would have imposed a one-time 5% tax on net worths exceeding $1 billion for residents. The measure aimed to raise funds for California’s Medicaid program but faced opposition from many wealthy individuals and business leaders who feared it could drive investment out of the state. The proposal was backed by economists like Gabriel Zucman and Emmanuel Saez, advocating for higher taxes on large fortunes, while others argued that punishing success would harm economic growth. Around 200 Californians would have been affected by this tax if passed.
