This event tracks the highest temperature that will be recorded in Seattle on a specific date in the future. The outcome depends on official weather data from a designated source, reflecting climate conditions and measurement accuracy.
All markets resolve based on the maximum temperature recorded at Seattle (CLISEA) on October 17, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 59° or below, 60-61°, 62-63°, 64-65°, 66-67°, or 68° and above. 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 participants should exercise caution when interpreting it. If the Exchange identifies a material error in the initial non-preliminary publication, it may delay expiration until a corrected revision is published 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 the market from potential adjustments due to errors.
