California’s proposed ‘billionaire tax’ fails to pass

Summary

• California voters rejected Proposition 40, a proposed one-time 5% wealth tax on residents with a net worth exceeding $1 billion.
• The measure failed after an expensive campaign pitting labor unions against wealthy tech figures & Governor Gavin Newsom.
• The tax would have been retroactive to January 1, 2026, & aimed to generate up to $100 billion over five years for public programs like Medi-Cal.
• Proponents noted California has over 200 billionaires holding approximately $2 trillion in cumulative wealth.
• Opponents argued the tax would cause capital flight, disincentivize growth, & potentially lose the state money over time.
• Critics including Nic Carter & Jesse Tinsely claimed the tax would inhibit venture capital investment & force founders to liquidate shares or cede control.
• Economist Emmanuel Saez stated the tax would dilute economic ownership but not voting rights, citing dual-class share structures as a solution.
• Saez noted California currently collects about $3 billion annually from the billionaire class, representing roughly 1% of total state revenue between 2025 & 2026.
• The "no" campaign raised roughly 10 times more than the "yes" side, with billionaires like Sergey Brin contributing up to $379 million.
• Supporters indicated they may place a similar tax on the ballot again in 2028.
