This event tracks the highest temperature reached in Philadelphia on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature recording for that day, reflecting climate conditions and forecasting challenges.
The event resolves based on the maximum temperature recorded in Philadelphia on September 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 84°F, 84–85°F, 86–87°F, 88–89°F, 90–91°F, or above 91°F. The Weather Company’s data is the sole authority, even if other sources differ. Preliminary data may be subject to rounding or conversion errors, and the Exchange reserves the right to delay resolution if a material error is identified in the initial report. If no valid data is available by the expiration date, markets 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 error-free data.
