Billionaire one-time wealth tax on California ballot?

Prediction market · Polymarket

Overview

This market will resolve to "Yes" if a ballot initiative is certified to appear on the official statewide California ballot for the November 3, 2026 election, that proposes a one-time tax targeting individuals, households, or family units with wealth, assets, or net worth of at least $1 billion (USD or equivalent), by June 25, 2026, 11:59 PM ET (the official cutoff date for new initiatives to be approved). Otherwise, this market will resolve to "No". Certification means the initiative is officially approved by the California Secretary of State for a statewide ballot. The primary resolution source will be official information from the government of California. If unavailable, a consensus of credible reporting may be used.

    "context_description": "**Trader consensus prices a 72.5% implied probability for the 2026 Billionaire Tax Act—a one-time 5% wealth tax on California residents' net worth exceeding $1 billion—appearing on the November statewide ballot, driven by steady signature-gathering momentum from sponsors SEIU-UHW and the Save California Health Care and Public Education campaign.** The initiative, cleared for circulation in December 2025, reported collecting 25% of the required 874,641 valid signatures (about 218,660) by late February 2026, with submission deadlines including April 17 for random sampling verification ahead of the June 25 certification cutoff. Endorsements from figures like Sen. Bernie Sanders and Rep. Ro Khanna bolster labor-led efforts, while March polls show 50-55% voter support for the measure funding Medi-Cal expansions and education. Opposition from billionaires, who have raised over $35 million for counter-initiatives, has spurred reports of wealth exodus but has not halted progress, per the latest updates. Historical union success in California ballot qualification underpins trader optimism.",
