Description

This event tracks the highest temperature reached in Seattle on a specific summer day in 2026. It categorizes possible temperature outcomes into ranges, each corresponding to a different resolution condition. The official temperature reading comes from a designated weather data provider.

Kalshi

The event resolves based on the maximum temperature recorded in Seattle (CLISEA) on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each representing a separate market outcome. If the recorded temperature falls within a specific range, the corresponding market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and methodology, ensuring consistency in evaluation. The secondary rule emphasizes that while other weather sources may offer similar data, The Weather Company's report is the sole authority for determining the final outcome.
