These markets focus on predicting Chicago's lowest temperature on a specific date in 2026. Outcomes depend on official weather data from a designated source, with specific temperature ranges determining results.
All markets resolve based on the minimum temperature recorded in Chicago (CLIMDW) on October 3, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: below 43°F, 43-44°F, 45-46°F, 47-48°F, 49-50°F, or above 50°F. The Weather Company’s data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication, the Exchange may delay resolution until a corrected value is released or until the expiration date. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company’s platform is informational and does not guarantee error-free data.
