This event tracks whether Seattle will experience specific temperature ranges on a particular day in the future. The outcome depends entirely on official weather data from a designated source, reflecting potential climate conditions for that exact date.
All markets resolve based on the maximum temperature recorded in Seattle (CLISEA) on October 28, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 50°F or below, 51-52°F, 53-54°F, 55-56°F, 57-58°F, or 59°F 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 users should exercise caution when interpreting it. 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 only and does not guarantee data accuracy or exempt markets from potential revisions.
