Description

This event tracks the highest temperature reached in Chicago on a specific date in the future, using data from a designated weather provider. Participants can speculate on whether the temperature will fall within certain ranges, helping to assess potential weather conditions for planning or curiosity.

Kalshi

The event determines whether the maximum temperature in Chicago on September 19, 2026, as recorded by The Weather Company, falls within specific Fahrenheit ranges. Each market corresponds to a distinct temperature band, with the highest band covering temperatures above 79°F. The Weather Company’s data is the sole authority for resolution. If preliminary data is later revised due to errors, the exchange may delay resolution until corrected data is published or until the expiration date. If data remains unavailable 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 data accuracy or exempt markets from potential revisions.
