Description

This set of markets focuses on predicting the highest temperature that will be recorded 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.

Kalshi

All markets resolve based on the maximum temperature recorded at Phoenix (CLIPHX) on October 24, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 75°F, 75-76°F, 77-78°F, 79-80°F, 81-82°F, or above 82°F. The official data from The Weather Company is the sole determinant, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting it. 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, whichever comes first. If 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 for convenience only and does not guarantee data accuracy or exempt markets from potential revisions.
