This event tracks whether specific temperature thresholds will be reached in Seattle on a particular date in the future. The outcome depends entirely on official weather data from a designated source, reflecting climate conditions rather than market predictions.
All markets resolve based on the maximum temperature recorded at Seattle (CLISEA) on October 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 69°F, 69-70°F, 71-72°F, 73-74°F, 75-76°F, or above 76°F. The Weather Company’s data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication before the expiration date, the exchange may delay resolution until a corrected value is released or until expiration, whichever comes first. If data remains unavailable at expiration, markets resolve to the last fair price determined by the exchange. The "Final" status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt markets from potential revisions.
