Description

This event tracks the lowest temperature recorded in Chicago on a specific future date, using data from a designated weather provider. The outcome depends on where the minimum temperature falls within predefined numerical ranges.

Kalshi

All markets resolve based on the minimum temperature recorded at Chicago's CLIMDW station on September 24, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 51°F or below, 52°F to 53°F, 54°F to 55°F, 56°F to 57°F, 58°F to 59°F, or 60°F and above. The Exchange holds final discretion to delay resolution if a material error is identified in preliminary data, extending until a corrected revision is published or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational and does not guarantee error-free data.
