This event tracks the peak temperature in Philadelphia on a specific summer day in 2026. The outcome depends on how hot it gets, with different ranges determining the result. Official data from the National Weather Service will be the sole source for verification.
The event resolves based on the highest temperature recorded at Philadelphia International Airport on July 23, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of the specified ranges—from 78° or below up to 87° or above—the respective market resolves to Yes. All outcomes rely exclusively on the NWS report, with preliminary or third-party data serving only as informal reference. Traders must recognize that NWS measurements may involve rounding or conversion nuances, necessitating careful interpretation of the final official figure.
