This event tracks whether Chicago will experience specific temperature ranges on a particular day in the future. The outcome depends entirely on official weather data from a designated source, reflecting anticipated climate conditions for that exact date.
All markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on October 30, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 60°F, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or above 67°F. The Weather Company’s data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication before expiration, the market may delay resolution until a corrected value is released or until the expiration date. If no data remains available by expiration, 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 error-free data.
