The rules, in plain English

This market resolves to "Up" if Silver (XAGUSD) closes higher on September 11, 2026 than on the most recent prior trading day. It resolves to "Down" if Silver closes lower on September 11, 2026 than on the most recent prior trading day. For example, a Monday market would normally compare to the previous Friday, unless Friday was not a trading day, in which case it would use the next most recent trading day. If the two closing prices are exactly equal, the market resolves 50-50. Closing prices are used exactly as published by Pyth, without rounding. If Silver does not trade at all during the relevant trading session, the market resolves 50-50. Trading days are determined by the Pyth trading-hours schedule. Under the standard schedule, trading is open from 6:00 PM ET Sunday through 5:00 PM ET Friday, with a daily break from 5:00 PM to 6:00 PM ET, except for holidays or special sessions. If September 11 is not a trading day, the market resolves 50-50. For each trading day, the closing price is the Pyth "Close" value of the 1-minute candle timestamped 4:59 PM ET on that date. If either relevant day has no valid Pyth Close value for the 4:59 PM ET candle, the market will use the last valid Pyth price before 4:59 PM ET during that trading day. If no valid Pyth price exists for that trading day due to system outage, data failure, or technical disruption, the CME COMEX Silver Futures (SI) official daily close price for that trading day may be used. Only prices achieved during the applicable trading session are considered. If there is a contract specification change, feed change, or similar structural modification during the time frame, the market resolves based on adjusted prices as displayed on Pyth. The resolution source is Pyth, specifically the "Close" values for the relevant 1-minute candle at https://pythdata.app/explore/Metal.XAG%2FUSD. Historical 1-minute candles can be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter.

What the rules leave open

What happens if the CME COMEX fallback source also lacks data or has a technical issue?
closest the rules come: “If no valid Pyth price exists for that trading day due to a system outage, data failure, or other technical disruption, the closing price for that day may be determined using the official daily close price of the CME COMEX Silver Futures (SI) futures contract for that trading day.” · market rules ↗
Whether 'may be determined' in the fallback clause means the platform has discretion or will automatically use CME data.
