This event tracks the highest temperature reached in San Francisco on a specific date in the future. The outcome depends on official weather data from a designated source, reflecting climate conditions for that day. Participants assess likelihood based on historical trends and forecasts.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 8, 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 data is the sole authority, with preliminary readings subject to revision. If a material error is identified before publication, the expiration may be delayed until a corrected value is released or until the expiration date. Should no data remain available 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 and does not guarantee immunity from revisions or errors.
