Resolution criteria on PolyGram: 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.

Market outcomes
| Billionaire one-time wealth tax on California ballot? | 93% YES | 8% NO |
California voters could face a ballot measure in November 2026 proposing a one-time wealth tax on billionaires if a qualifying initiative is certified by the Secretary of State before 25 June 2026. The measure would target individuals or households with at least $1 billion in wealth, assets, or net worth. Certification requires the initiative to gather sufficient valid signatures and meet procedural requirements set by California law. The current Polymarket order book reflects a 93% implied probability, suggesting traders assess certification as highly likely within the timeframe.
Comparable wealth tax initiatives in California provide context for evaluating this probability. In 2020, a proposed wealth tax initiative failed to qualify for the ballot despite significant backing. However, recent years have seen increased momentum around wealth taxation proposals nationally, with several states exploring similar mechanisms. The 2024 election cycle demonstrated renewed appetite for progressive taxation measures, particularly in high-income jurisdictions. These precedents suggest both that wealth tax initiatives face genuine structural hurdles in signature gathering and legal challenges, yet also that political conditions have shifted to make such measures more viable than previously.
Traders should monitor signature-gathering progress and any legal challenges to the initiative's validity. The California Secretary of State's office publishes regular updates on initiative status. Key dates include the signature deadline (typically 150 days before the election) and the certification announcement. Recent reporting on similar progressive taxation efforts in California and other states will signal whether political momentum continues. Any court rulings on initiative language or eligibility could materially affect certification prospects before the June 2026 deadline.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
