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 6 Sep '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. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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.
Recent National Weather Service and NOAA model guidance positions Chicago's September 6 high in the upper 70s, driving trader consensus toward the 78-79°F outcome at 53.5% implied probability and 76-77°F at 35%. A pronounced cooldown followed the record-warm early-September heat wave, with northeast flow off Lake Michigan moderating afternoon temperatures and limiting mixing. Official forecasts highlight partly cloudy skies, light easterly winds, and highs near 75-77°F at O'Hare, consistent with climatological norms for early fall. Market positioning reflects uncertainty in exact lake-effect modulation and any late-day warming, with resolution hinging on the final verified maximum from primary stations.
