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.
All markets resolve based on the minimum temperature recorded at Philadelphia (CLIPHL) on September 13, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 65°F or below, 66°F to 67°F, 68°F to 69°F, 70°F to 71°F, 72°F to 73°F, or 74°F and above. The Exchange holds expiration if a material error is identified in the initial data publication, extending it until a corrected revision is issued or the expiration date arrives. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, and the "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy.
