This event tracks whether specific temperature thresholds will be reached in Seattle on a particular day in the future. The outcome depends entirely on official weather data from a designated source, with mechanisms to address potential data discrepancies.
All markets resolve based solely on the maximum temperature recorded at Seattle (CLISEA) on October 29, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 52°F, 52-53°F, 54-55°F, 56-57°F, 58-59°F, or above 59°F. The Exchange retains discretion to delay resolution if material errors are identified in preliminary data, extending until either a corrected publication or the expiration date. If data remains unavailable by expiration, markets resolve at the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not override these resolution procedures.
