Proposition 40, a one-time billionaire wealth tax, qualified for California's November 3, 2026 ballot, yet markets price passage at just 28%.
Proposition 40 was certified for California's November 3, 2026 general election ballot on June 25, formally qualifying the measure that asks voters whether a billionaire one-time wealth tax passes in California election this cycle. Filed as Initiative No. 25-0024 under the 2026 Billionaire Tax Act, the legislation would impose a one-time levy on the accumulated net worth of California residents holding at least $1 billion, with proceeds directed to state-funded healthcare, education, and food assistance programs. Analysts note the headline rate is 5 percent, though the Tax Foundation warned that aggressive design choices and possible drafting errors could push the effective rate on some taxpayers' net worth dramatically higher.

The campaign has drawn national political figures into the fight over whether the billionaire one-time wealth tax passes in California election voting. Bernie Sanders publicly criticized a Google co-founder for spending millions to defeat the proposal, sharpening the measure's framing as a referendum on ultra-wealthy influence. Proponents argue the levy targets fewer than 200 residents while funding social programs; opponents cite legal headwinds, potential taxpayer flight, and constitutional questions flagged by advisory firms monitoring the initiative's progress.

Passage odds have edged upward but remain skewed toward rejection. Polygon-based pricing recently placed the outcome near 32 percent, up 1 point over the prior week and 4 points over the past month, while aggregated feeds pooling Kalshi and Polymarket venues showed No at roughly 69.8 percent against Yes near 30.2 percent as of late August. With the vote roughly ten weeks out, campaign spending disclosures, legal challenges, and statewide polling on the ballot question are the key milestones to watch before Election Day.
