This set of markets focuses on predicting the lowest temperature that will occur in Phoenix 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.
All markets resolve based solely on the minimum temperature recorded at Phoenix (CLIPHX) on September 6, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 77°F or below, 78-79°F, 80-81°F, 82-83°F, 84-85°F, or above 85°F. The official data from The Weather Company is the definitive source, and users should exercise caution with preliminary readings due to potential rounding or conversion discrepancies. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version is released or until the expiration date. In cases where data remains unavailable by the expiration date, 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 potential adjustments.
