Kalshi
This event tracks the lowest temperature that will be recorded in Philadelphia on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.
All markets resolve based on the minimum temperature recorded at Philadelphia (CLIPHL) on September 22, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 52°F or below, 53°F to 54°F, 55°F to 56°F, 57°F to 58°F, 59°F to 60°F, or above 60°F. The Exchange reserves the right to delay expiration if a material error is identified in the initial data publication, allowing time for a corrected revision. If no data becomes available by the Expiration Date, markets will resolve to the last fair price determined by Kalshi. Preliminary data may differ from final reported values due to rounding or conversion, so participants should exercise caution when interpreting early readings. The status of "Final" on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential adjustments.
