Description

This event tracks the highest temperature reached 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, reflecting possible weather conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded in Seattle (CLISEA) on October 18, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded temperature falls within that range. All markets share identical secondary rules regarding data verification and error handling. The Exchange retains discretion to delay resolution if a material error is identified in the initial data publication, allowing time for a corrected value to be released. If no valid data becomes available by the expiration date, markets will resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company's platform is informational only and does not guarantee data accuracy or exempt the data from potential revision under these rules.
