**Official National Weather Service climatological summaries for September 19, 2026, recorded a daily maximum of 70°F at Chicago O’Hare International Airport, the primary station for such records, with the high occurring in the afternoon.** This measurement aligns precisely with the market’s dominant 70-71°F outcome and explains the 99.6% implied probability, as traders incorporate verified station data once the calendar day concludes. Supporting context includes a minimum of 63°F, above-normal overnight lows, and precipitation totals around 0.5–0.86 inches, consistent with a cool, moist air mass that limited daytime heating below the September normal of 74–75°F. Realistic scenarios that could alter the outcome include a post-event data revision from the reporting station, resolution criteria tied to a secondary site such as Midway (which reached 72°F), or an unexpected adjustment in how “highest temperature” is defined for the contract. In the absence of such anomalies, the NWS-verified observation anchors near-certain trader consensus.

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 19 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 climatological summaries for September 19, 2026, recorded a daily maximum of 70°F at Chicago O’Hare International Airport, the primary station for such records, with the high occurring in the afternoon.** This measurement aligns precisely with the market’s dominant 70-71°F outcome and explains the 99.6% implied probability, as traders incorporate verified station data once the calendar day concludes.
