This set of markets focuses on predicting the lowest temperature that will be recorded in Louisville 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 climate forecasting accuracy for that particular day and location.
All markets resolve based on the minimum temperature recorded at Louisville (CLISDF) on September 11, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The official data from The Weather Company is the sole determinant, and users should exercise caution with preliminary readings due to potential 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 the event that no data remains 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 informational only and does not guarantee data accuracy or exempt markets from these resolution procedures.
