This event tracks the highest temperature recorded in San Francisco on a specific date in the future, using data from a designated weather provider. Participants can assess various temperature ranges to predict how warm the day will be, with outcomes determined by official weather measurements.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 11, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to Yes if the recorded high 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, even if other sources report different values. Preliminary data may be subject to rounding or conversion discrepancies, so users should exercise caution. If the Exchange identifies a material error in the initially published data, it may delay expiration until a corrected version is released or until the expiration date arrives, whichever comes first. Should no data remain available by the expiration date, all markets resolve to the last fair price established by Kalshi. The “Final” status on The Weather Company’s platform is informational only and does not shield the data from potential revisions under these rules.
