The Aporia · California billionaire tax measure defeated in contentious vote

California voters rejected Proposition 40, which aimed to implement a new wealth tax targeting billionaires, despite a projected Democratic surge in the midterm elections. Proponents estimated that Prop 40 could raise $100 billion for healthcare programs but failed due to opposition largely centered around recent federal tax breaks favoring wealthy individuals and corporations enacted under President Trump’s administration. The measure's defeat is seen as a setback for progressive policies aimed at addressing economic inequality.

Story summary

Californians voted against Proposition 40 on November 3, 2026, which would have imposed a one-time 5% tax on the fortunes of billionaires with assets over $1 billion. The measure aimed to raise approximately $100 billion for healthcare programs but was defeated with 53.8% voting against it and 47.2% in favor, according to The Associated Press.

Proposition 40 divided liberal leaders nationally; while Vermont Senator Bernie Sanders framed the proposal as a step toward reducing wealth inequality, Democratic Governor Gavin Newsom warned that it would drive wealthy residents out of California. Opponents argued that Proposition 40 was not sustainable and failed to address broader economic issues effectively. The campaign over Proposition 40 became the most expensive in state history due to significant contributions from both supporters and opponents, including tech billionaires like Elon Musk.
