Description

This event tracks whether specific temperature thresholds will be met in San Francisco on a particular date in the future. Outcomes depend entirely on official weather data from a designated source, reflecting climate conditions rather than market predictions.

Kalshi

All markets resolve based on the maximum temperature recorded at San Francisco (CLISFO) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 69°F, 69–70°F, 71–72°F, 73–74°F, 75–76°F, or above 76°F. The Exchange holds expiration if a material error is identified in the initial data publication, extending it until a corrected revision or the official expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, and the 'Final' status on Weather Company platforms does not guarantee error-free data.
