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 temperatures will fall within certain ranges, helping to gauge expected weather conditions for that day.
The event determines whether the maximum temperature in Chicago on October 26, 2026, as recorded by The Weather Company, falls within specific degree ranges. Each market corresponds to a temperature band, with one market resolving if temperatures are 69°F or lower, and others resolving for incremental ranges up to 69-70°F and above. The Weather Company serves as the sole source for official temperature data. All markets share secondary rules addressing data reliability: preliminary readings may vary due to rounding or conversion issues, and the Exchange reserves the right to delay resolution if material errors are identified in initial reports. If data remains unavailable by the expiration date, markets resolve at the last fair price determined by the Exchange. The "Final" status on The Weather Company’s platform is informational and does not exempt the data from potential revision under these rules.
