This event tracks the highest temperature that San Francisco will experience on a specific future date, using a single authoritative weather data source to determine the outcome. Participants can assess various temperature ranges to predict how warm the city will get on that day.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on October 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 bounds. All markets share identical secondary rules regarding data verification: while other weather services may offer similar data, The Weather Company’s report is the sole arbiter. Preliminary data may be subject to rounding or conversion discrepancies, requiring caution in early interpretations. The exchange retains discretion to delay resolution if a material error is identified in the initial publication, extending the evaluation period until a corrected figure is released or the expiration date passes. Should final data remain unavailable by the expiration date, all markets resolve based on the last fair price established by Kalshi. The “Final” status indicated on weather.com/kalshi is informational only and does not immunize the data from potential revisions under these rules.
