This event tracks the lowest temperature recorded in Seattle on a specific date in the future, using data from a designated weather service. The outcome depends entirely on how cold it gets during that overnight period, with different temperature ranges determining the result.
All markets resolve based solely on the minimum temperature recorded at Seattle (CLISEA) on October 12, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 35°F, 35-36°F, 37-38°F, 39-40°F, 41-42°F, or above 42°F. The Weather Company's official reporting serves as the definitive source, even if other services show different values. Preliminary data may be subject to rounding or conversion differences, so participants should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary data publication, it may delay expiration until a corrected version is released or until the expiration date arrives, whichever comes first. Should no data remain 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 provided for convenience but does not guarantee data accuracy or exempt markets from potential revisions under these error-resolution procedures.
