Description

This event tracks the lowest temperature recorded in San Francisco on a specific future date, using data from a designated weather provider. The outcome depends on where the minimum temperature falls within predefined ranges, reflecting possible weather conditions for that day.

Kalshi

The event resolves based on the minimum temperature recorded in San Francisco on October 21, 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 a specific range, that market resolves to Yes, with all others resolving to No. All markets share common 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 material errors are identified in initial reports. If no valid data is available by the expiration date, markets resolve to the last fair price determined by the Exchange. The status of 'Final' on The Weather Company's platform is informational only and does not guarantee immunity from revisions or errors.
