This set of markets focuses on predicting the highest temperature that will be recorded in Phoenix on a specific date in the future. Participants can bet on different temperature ranges, with each range representing a possible outcome based on official weather data.
All markets resolve based on the maximum temperature recorded at Phoenix (CLIPHX) on October 10, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: less than 89°F, 89-90°F, 91-92°F, 93-94°F, 95-96°F, or greater than 96°F. The Weather Company’s data is the sole authority for resolution. Preliminary data may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial data 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 the Exchange. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential revisions.
