This set of markets focuses on predicting the highest 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, reflecting anticipated climate conditions for that day.
All markets resolve based on the maximum temperature recorded at Philadelphia (CLIPHL) on October 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 64°F or below, 65-66°F, 67-68°F, 69-70°F, 71-72°F, or 73°F and above. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary readings may differ from final reported values due to rounding or conversion differences. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. In cases where data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt markets from potential revisions.
