This set of markets focuses on predicting the lowest 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 for that day.
These markets resolve based on the minimum temperature recorded in Phoenix (CLIPHX) on September 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 80° or below, 81-82°, 83-84°, 85-86°, 87-88°, or 89° and above. If the recorded minimum temperature falls within a market's specified range, that market resolves to Yes; all others resolve to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may be subject to rounding or conversion differences, so participants should exercise caution when interpreting early readings. If the Exchange determines there is a material error in the initial non-preliminary publication, the expiration may be delayed until a corrected revision is published or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The status of “Final” on weather.com/kalshi is provided for convenience only and does not guarantee data accuracy or exempt the market from these error-resolution procedures.
