Description

This event tracks the highest temperature reached in Seattle on a specific date in 2026. The outcome depends on how warm it gets, with different markets covering various temperature ranges. The official temperature reading comes from a designated weather service.

Kalshi

The event resolves based on the maximum temperature recorded in Seattle (CLISEA) on September 7, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a specific market outcome. If the temperature falls within a given range, that market resolves to Yes; all others resolve to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to revision, and the exchange retains discretion to delay resolution for material errors. If final data remains unavailable by expiration, markets resolve to the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational only and does not guarantee error-free data.
