About this market

Context

This market will resolve to "Yes" if Kamala Harris announces that she will vote for Zohran Mamdani or endorses Mamdani for the 2025 NYC Mayor election between June 26, and November 3, 2025, 11:59 PM ET. Otherwise this market will resolve to "No". If Kamala Harris announces that she will vote for another candidate or endorses another candidate for NYC Mayor, this market will immediately resolve to "No". The resolution source for this market will be official information from Kamala Harris or one of her representatives, or a consensus of credible reporting of Kamala Harris's endorsement.

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.
