This event tracks the highest temperature reached in San Francisco on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 10, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves 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 material errors are 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 status of “Final” on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt markets from potential revisions.
