This event tracks whether Seattle will experience specific temperature ranges on October 31, 2026, based on official weather data. Participants can assess the likelihood of various temperature outcomes for that exact date, influenced by seasonal climate patterns and local weather forecasts.
The event determines the resolution of multiple temperature outcome markets for Seattle on October 31, 2026, using maximum temperature data from The Weather Company as the sole authoritative source. Each market corresponds to a specific temperature range: below 52°F, 52-53°F, 54-55°F, 56-57°F, 58-59°F, and above 59°F. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may undergo revisions due to rounding or conversion discrepancies, and the Exchange retains discretion to delay expiration if material errors are identified in initial publications. If final data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The "Final" status on Weather Company platforms is advisory only and does not exempt data from potential corrections under these rules.
