Official National Weather Service observations at Chicago O’Hare and Midway airports recorded a daily maximum of 80°F on September 9, 2026, aligning closely with the market’s overwhelming 78-79°F consensus at near-100% implied probability. This outcome reflects a modest positive departure from the 1991-2020 normal high near 78-79°F, influenced by persistent cloud cover, light rain, and fog that limited further warming despite regional late-summer warmth. Forecast model consensus and real-time station data converged on this narrow range well before sunset, leaving minimal room for revision. Realistic challenges would require significant post-observation adjustments to official climatological reports or redefinition of the “highest temperature” metric, both highly unlikely given established NWS verification protocols.

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 9 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.Official National Weather Service observations at Chicago O’Hare and Midway airports recorded a daily maximum of 80°F on September 9, 2026, aligning closely with the market’s overwhelming 78-79°F consensus at near-100% implied probability.
