Highest temperature in Chicago on Oct 11, 2026?

Kalshi

All markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on October 11, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 72° or below, 73-74°, 75-76°, 77-78°, 79-80°, and 81° or above. The official data from The Weather Company is the sole determinant, though participants may reference other sources for guidance. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi.
