Traders have overwhelmingly priced 62-63°F as the highest temperature recorded in Chicago on September 22 because official NOAA station observations and National Weather Service summaries confirmed a daily maximum in that narrow range. This outcome aligns with the arrival of a cooler air mass behind a passing frontal boundary that suppressed afternoon heating across the Midwest, keeping readings below the late-September climatological average near 70°F. Verified surface data released shortly after the observation window eliminated nearly all uncertainty, producing the near-100% market-implied probability. Only an unusually large post-analysis correction to the official record could alter the result, an infrequent occurrence once preliminary measurements undergo quality control.

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 22 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.Traders have overwhelmingly priced 62-63°F as the highest temperature recorded in Chicago on September 22 because official NOAA station observations and National Weather Service summaries confirmed a daily maximum in that narrow range.
