These markets track whether Chicago's maximum temperature on October 23, 2026, will fall within specific ranges. Each outcome corresponds to a different temperature band, with the highest band covering temperatures above a threshold. The resolution depends solely on data from The Weather Company for Chicago's CLIMDW station.
All markets resolve based on the maximum temperature recorded at Chicago's CLIMDW weather station on October 23, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 69°F, 69–70°F, 71–72°F, 73–74°F, 75–76°F, or above 76°F. The Weather Company’s data is the sole authority for resolution. Preliminary readings may differ from final values due to rounding or conversion, so participants should exercise caution. 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 market’s expiration date. 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 guarantee error-free data.
