This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 24 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Current National Weather Service guidance and supporting model runs indicate a high of 74–78°F for Chicago on August 24 under mostly sunny skies and light northwest-to-northeast winds, with Lake Michigan moderating shoreline readings. This stable air mass, limited warm advection, and recent cooler-than-normal conditions have concentrated trader consensus on the 76–77°F (51%) and 78–79°F (40%) bins, as these align with expected peak values once urban heat and minor model timing differences are considered. Normal late-August highs near 82°F are offset by the prevailing synoptic pattern, keeping probabilities for 80°F+ below 7% combined. Resolution depends on official observations at Chicago stations.
