This set of markets will resolve based on the actual highest temperature recorded 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 on that day.
These markets resolve based on the maximum temperature recorded in Philadelphia on September 14, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, or above 81°F. The official data from The Weather Company is the sole determinant, even if other sources report different values. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If no valid data is available by the expiration date, markets will resolve to the last fair price determined by the Exchange. The "Final" status on The Weather Company’s platform is informational and does not guarantee data accuracy or exempt markets from potential adjustments.
