Description

This event tracks the lowest temperature recorded in San Francisco on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.

Kalshi

The event resolves based on the minimum temperature recorded in San Francisco (CLISFO) on September 4, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded minimum temperature falls within a specific range, the associated 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 reserves the right to delay resolution if a material error is identified in the initial publication. If no valid data is available by the expiration date, markets will 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 data accuracy or exempt the data from potential revisions under these rules.
