This set of markets focuses on predicting Philadelphia's lowest temperature on a specific date in 2026. Outcomes depend entirely on official weather data from a designated source, with markets covering different temperature ranges.
All markets resolve based on the minimum temperature recorded in Philadelphia on October 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 48°F, 48-49°F, 50-51°F, 52-53°F, 54-55°F, or above 55°F. The Weather Company serves as the sole authority for temperature data. Preliminary readings may differ from final values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version appears or until the market expiration date. Should no data remain available by the expiration deadline, markets resolve at the last fair price established by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not shield against potential data revisions or errors.
