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 for that day, with all markets resolving based on predefined temperature ranges.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 9, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that resolves to Yes if the recorded temperature falls within its specified range. All markets share identical secondary rules regarding data verification and error handling. The Weather Company’s official reporting serves as the sole source of truth, with preliminary data subject to potential revision. If a material error is identified in the initial publication before the market’s expiration, the exchange retains discretion to extend the evaluation period until a corrected value is published or until the expiration date, whichever occurs first. Should no reliable data remain available by the expiration date, all markets resolve to the last fair price determined by the exchange. The status of "Final" on The Weather Company’s platform is strictly informational and does not exempt the data from potential revision under these rules.
