This event tracks the lowest temperature recorded in Philadelphia on a specific future date, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.
All markets resolve based on the minimum temperature recorded at Philadelphia (CLIPHL) on September 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 47° or below, 48-49°, 50-51°, 52-53°, 54-55°, or 56° or above. The Weather Company's official report is the sole source for determining resolution, even if other weather services show different values. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary publication, it may delay expiration until a corrected revision is published 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 weather.com/kalshi is provided for convenience but does not guarantee data accuracy or exempt markets from potential error resolution procedures.
