Lowest temperature in Chicago on Sep 12, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded in Chicago (CLIMDW) on September 12, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 61°F, 61-62°F, 63-64°F, 65-66°F, 67-68°F, or above 68°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 before the expiration date, the market may delay resolution until a corrected value is released or until the expiration date itself. Should no data remain available by the expiration date, markets resolve to the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
