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 climatic conditions on that day.
These markets resolve based on the maximum temperature recorded in Phoenix (CLIPHX) on October 25, 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, and above 85°F. The market associated with the actual recorded temperature range will resolve to Yes, while all others resolve to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may undergo revisions, and the Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If no valid data is available 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 revisions under these rules.
