California voter ID referendum passes?

The California voter ID initiative is a proposed statewide ballot measure for the California general election currently scheduled for November 3, 2026, which would require voters to present government-issued identification in California elections. This market will resolve to “Yes” if the voter identification initiative proposed by Reform California or any other statewide ballot measure that establishes a voter ID requirement for voting in California elections is approved by a majority of voters at the California statewide general election currently scheduled for November 3, 2026. Otherwise, this market will resolve to “No.” If by the last legally operative deadline for placing measures on the November 3, 2026 statewide ballot, including any deadline set or modified by statute governing the initiative qualification process, no qualifying voter identification initiative has been approved for submission to voters, and there is no enacted statute or pending court order that could still place such a measure on that ballot, the market will resolve “No”. If the election is officially rescheduled, the same rule applies to the new ballot and its corresponding deadlines. The resolution source will be based on the official certified results of the vote as published by the California Secretary of State. Subsequent litigation, administrative challenges, or failure of any post-approval triggers will not be considered.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
