This set of markets focuses on predicting the highest temperature that will be recorded in Philadelphia on a specific date in the future. Participants can bet on different temperature ranges, with each outcome determined by official weather data from a designated source.
All markets resolve based on the maximum temperature recorded at Philadelphia (CLIPHL) on October 10, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 69° or below, 70-71°, 72-73°, 74-75°, 76-77°, or 78° and above. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary readings may differ from the final reported value due to rounding or conversion differences. If a material error is identified in the initial publication, the Exchange reserves the right to delay expiration until a corrected value is released or until the expiration date, whichever comes first. In the event that no data is available by the expiration date, 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 revisions.
