Description

This event tracks the highest temperature reached in Seattle on a specific date in 2026. The outcome depends on how warm it gets on that day, with different markets covering various temperature ranges. All markets use data from a single official source to determine the result.

Kalshi

All markets resolve based on the maximum temperature recorded in Seattle (CLISEA) on September 8, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 69° or below, 70-71°, 72-73°, 74-75°, 76-77°, or 78° and above. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending the period until a corrected value is released or the expiration date arrives. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. While other weather sources may show different values, only The Weather Company's official report is used for resolution, and preliminary data may differ from the final reported value due to rounding or conversion differences.
