Description

This event tracks the highest temperature reached in Philadelphia on a specific date, using official government data as the definitive source. It helps participants assess climate conditions and temperature trends for a particular day in the future.

Kalshi

The event resolves based on the highest temperature recorded at Philadelphia International Airport on August 1, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six separate temperature ranges are defined, each corresponding to a different market outcome. If the recorded temperature falls within any of these specified ranges, the associated market resolves to Yes. All outcomes share the same data source and methodology, with the NWS report serving as the exclusive authority for determining the final result. Traders must recognize that preliminary data from other services may differ, and official rounding or conversion methods applied by NWS could affect interpretations until the final report is published.
