This event tracks the lowest nighttime temperature in Philadelphia on a specific date next year. The outcome depends entirely on official government weather records, making it a straightforward test of actual climate conditions rather than predictions or models.
All markets resolve based solely on the official minimum temperature recorded by the National Weather Service's Climatological Report (Daily) for Philadelphia, PA on July 31, 2026. Each market corresponds to a specific temperature range: below 63°F, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The exact temperature value from the NWS report determines the resolving market, with no consideration for preliminary or third-party data sources. Traders must rely on the final, official NWS data once it becomes available, as preliminary reports may undergo revisions or corrections. The rules emphasize that while external weather services may offer guidance, only the NWS report serves as the binding authority for resolution.
