Official observations from the National Weather Service at Chicago O’Hare International Airport—the standard reference for such markets—recorded a daily maximum temperature of 78–79°F on August 17, 2026. This outcome aligned with ensemble model guidance showing a moderating air mass, increased cloud cover, and limited daytime heating that suppressed temperatures well below the 82–83°F climatological normal. Traders converged on this narrow bin because real-time surface data and post-event verification left virtually no room for deviation, producing 100% implied probability. Realistic challenges would require an official data revision from NWS, use of an alternate station with different readings, or an undetected measurement error—scenarios that remain unlikely given the high reliability of automated airport instrumentation and routine quality control.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 17 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Chicago O'Hare Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/il/chicago/KORD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.Official observations from the National Weather Service at Chicago O’Hare International Airport—the standard reference for such markets—recorded a daily maximum temperature of 78–79°F on August 17, 2026.
