Description

This event tracks whether a specific temperature range will be reached in San Francisco on a particular day in 2026. The outcome depends solely on official weather data from a designated source, with specific procedures for handling data discrepancies or delays.

Kalshi

All markets resolve based on the maximum temperature recorded at San Francisco (CLISFO) on October 29, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The official data source is The Weather Company, and while other weather services may show similar information, they do not affect the resolution. Preliminary data may be subject to rounding or conversion differences, so participants should exercise caution. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If no data is available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential revisions.
