Description

This event tracks the highest temperature reached in Seattle on a specific summer day in 2026. It categorizes possible temperature outcomes into ranges, allowing participants to speculate on how unusually hot the day might become. The resolution depends on official weather data from a designated source.

Kalshi

The event resolves based on the maximum temperature recorded in Seattle (CLISEA) on August 20, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the recorded temperature falls within a given range, that market resolves to Yes; all others resolve to No. While alternative weather sources may offer differing readings, The Weather Company’s data serves as the exclusive, binding authority for determination. This structure ensures clarity and consistency in evaluating the event’s outcome across all participating markets.
