This set of markets focuses on predicting the highest temperature that will occur in Phoenix on a specific date in the future. Participants can bet on different temperature ranges, with the outcome determined by official weather data from a designated source.
These markets resolve based on the maximum temperature recorded in Phoenix (CLIPHX) on October 22, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 78° or below, 79-80°, 81-82°, 83-84°, 85-86°, and 87° or above. The official data from The Weather Company is the sole determinant of resolution, even if other sources report different values. Preliminary data may be subject to rounding or conversion differences, and participants should exercise caution when interpreting early readings. 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. 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 and does not guarantee data accuracy or exempt markets from potential revisions.
