Description

This event tracks the lowest temperature recorded in Seattle on a specific date in the future, using data from a designated weather provider. The outcome depends on where the temperature falls within predefined ranges.

Kalshi

All markets resolve based on the minimum temperature recorded in Seattle (CLISEA) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 46°F or below, 47°F to 48°F, 49°F to 50°F, 51°F to 52°F, 53°F to 54°F, or 55°F and above. The Exchange may delay resolution if it identifies a material error in the initial data publication, allowing time for a corrected report or proceeding to the Expiration Date. If data remains unavailable by the Expiration Date, markets resolve to the last fair price determined by Kalshi. Preliminary data may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only and does not guarantee error-free data.
