This market will resolve to "Yes" if at least one inmate is officially held at Alcatraz Federal Penitentiary on Alcatraz Island by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The inmate must be detained by the U.S. federal government as part of a formal correctional or detention program. Temporary holds of less than 24 hours or symbolic events will not count. The resolution source will be a consensus of credible reporting.
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.
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.
