Description

This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.

Kalshi

The event determines whether the minimum temperature in Chicago on September 11, 2026, falls within specific Fahrenheit ranges, with outcomes resolving based on data from The Weather Company. Each market corresponds to a distinct temperature range: 56°F or below, 57-58°F, 59-60°F, 61-62°F, 63-64°F, or 65°F and above. The official temperature value comes exclusively from The Weather Company, and users should exercise caution with preliminary data due to potential rounding or conversion discrepancies. If the Exchange identifies a material error in the initially published data, it may delay resolution until a corrected version is released or until the expiration date, whichever occurs first. Should no data remain available 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 only and does not guarantee data accuracy or exemption from revision.
