Trader consensus has converged on the 78-79°F outcome at full implied probability following official observations from the National Weather Service at Chicago O’Hare International Airport, the primary resolution station. This reading aligns with National Weather Service model guidance for a stable air mass, light northwest winds shifting northeast, and Lake Michigan moderation suppressing peak temperatures below late-August climatological normals near 82°F. Recent cooler-than-normal conditions on August 23 further limited warming despite mostly sunny skies. The market’s 100% positioning reflects verified data rather than forecast uncertainty, though minor resolution risk remains from station-specific microclimate effects or post-observation revisions.

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.Trader consensus has converged on the 78-79°F outcome at full implied probability following official observations from the National Weather Service at Chicago O’Hare International Airport, the primary resolution station.
