This event tracks the highest temperature reached in Philadelphia on a specific date in the future. The outcome depends entirely on official weather data from a designated source, reflecting real-world climate conditions and measurement practices.
The event resolves based on the maximum temperature recorded in Philadelphia on September 8, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves to No. All outcomes share identical secondary rules regarding data verification and error handling. The Exchange retains discretion to delay resolution if material errors are identified in preliminary data, extending the evaluation period until either corrected data is published or the expiration date passes. In cases where data remains unavailable by the expiration date, markets resolve to the last fair price determined by the Exchange. The status of 'Final' on The Weather Company's platform is informational only and does not override these resolution procedures.
