About this market
ContextThis market will resolve to "Up" if the closing price for COMEX Gold Futures (GC=F) on Tuesday, October 28, 2025 is higher than the closing price for GC=F on the most recent prior trading day. This market will resolve to "Down" if the closing price for COMEX Gold Futures (GC=F) on Tuesday, October 28, 2025 is lower than the closing price for GC=F on the most recent prior trading day. E.g., ordinarily, a market on Monday would refer to the previous Friday for its most recent closing price, unless that Friday were a market holiday, in which case it would refer to Thursday, or the next most recent trading day. If the two specified closing prices are exactly equal, this market will resolve 50-50. Note that all figures will be rounded to the nearest cent using standard rounding. If GC=F does not trade at all during the regular session, the market will resolve 50-50. If either of the relevant days are shortened (for example, due to a market holiday schedule), the official closing price published for that shortened session will still be used for resolution. If either of the relevant days have no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source for this market is Yahoo Finance, specifically the close values published by Yahoo Finance, under 'Historical Data'.
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.
