Official measurements from National Weather Service stations, including Chicago O'Hare, recorded a daily maximum of 74–75°F on September 13, 2026, under partly cloudy skies with a moderating northerly flow and dew points in the 50s that limited afternoon heating. This aligned with the National Weather Service forecast discussion emphasizing mid-70s highs due to a post-frontal air mass and minimal insolation from scattered clouds. Trader consensus at 100% implied probability for the 74–75°F bin reflects confirmed observational data rather than models. Resolution could face minor challenge only from rare station-specific discrepancies or quality-control revisions, though such adjustments remain improbable given consistent regional reports.

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.
