Description

This event tracks the highest temperature reached in San Francisco on a specific date in the future, using data from a designated weather provider. The outcome depends solely on the official temperature recording, with specific ranges determining different results.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on October 9, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within any specified 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 or unresolved data. In the absence of final data by the expiration date, 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 override these resolution procedures.
