This event tracks the lowest temperature recorded in Philadelphia on a specific future date, using official government data. The outcome depends entirely on the exact temperature reading from the National Weather Service's official report for that day.
All markets resolve based solely on the official minimum temperature recorded in Philadelphia on July 26, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 55°F or below, 56-57°F, 58-59°F, 60-61°F, 62-63°F, or above 63°F. The exact temperature value from the NWS report determines the resolving market, with no consideration given to preliminary or third-party data sources. Traders must rely exclusively on the final NWS report, noting that reporting schedules and potential rounding conventions may affect interpretation. All secondary instructions point to the same official data source and emphasize caution regarding preliminary readings.
