Description

This event tracks the highest temperature recorded in San Francisco on a specific date in the future. The outcome depends solely on official weather data from a designated source, reflecting climate conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded in San Francisco (CLISFO) on September 24, 2026, as reported by The Weather Company. Six separate outcome ranges are defined: 71° or below, 72-73°, 74-75°, 76-77°, 78-79°, and 80° or above. Each market corresponds to one of these temperature ranges, with the 'Yes' outcome triggered if the actual temperature falls within that specific range. All markets share identical secondary rules regarding data verification: preliminary Weather Company data may contain rounding or conversion discrepancies, and the Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by the Exchange. The 'Final' status on weather.com/kalshi is informational only and does not guarantee error-free data.
