This event tracks the lowest temperature recorded in Philadelphia on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.
The event resolves based on the minimum temperature recorded in Philadelphia on September 23, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 49°F or below, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or 58°F and above. The official data source is The Weather Company, and all participants must rely on its final reported value, even if other weather services show different numbers. Preliminary readings may be subject to rounding or conversion differences, so caution is advised. If the Exchange determines there is a material error in the initial data publication, the expiration may be delayed until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is for convenience only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
