Description

This event tracks whether specific temperature thresholds will be reached in Seattle on a particular date in 2026. The outcome depends entirely on official weather data from a designated source, with specific ranges defining success for each market.

Kalshi

All markets resolve based on the maximum temperature recorded at Seattle (CLISEA) on September 11, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 65° or below, 66-67°, 68-69°, 70-71°, 72-73°, or above 73° Fahrenheit. The Exchange holds expiration if a material error is identified in the initial data publication, extending it until a corrected revision or the official Expiration Date, whichever comes first. If data remains unavailable by the end of this period, markets resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only and does not exempt data from potential revision or error correction.
