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 on where the temperature falls within predefined ranges, reflecting varied weather conditions for that day.
The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on October 20, 2026, as reported by The Weather Company. Six separate markets cover distinct temperature ranges: 63° or below, 64-65°, 66-67°, 68-69°, 70-71°, and 72° or above. Each market resolves to Yes if the recorded temperature falls within its specified range. All markets share common secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is the official determinant. If a material error is identified in the initial publication, the Exchange may delay expiration until a corrected value is released or until the expiration date, whichever comes first. If no data remains available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The “Final” status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt the market from these error-resolution procedures.
