**Official observations from the National Weather Service at Chicago O'Hare recorded a daily maximum of 80°F on September 9, 2026, aligning closely with the market's near-certain 78-79°F bin (99.7% implied probability).** This outcome reflected seasonal conditions moderated by cloud cover, morning showers, and a passing cold front that limited afternoon heating. The high occurred around 2:27 PM local time under mostly cloudy skies with light rain, keeping values just 2°F above the 1991-2020 normal of 78°F. Trader consensus draws from real-time NWS climatological reports and preliminary local climatological data (CF6), which provide authoritative, station-specific measurements used for market resolution. Broader context includes the month's early heat wave (multiple 90s+ days in early September), but a shift to cooler, moister air masses on the 9th prevented further warming. Historical analogs for mid-September show typical highs in the upper 70s, supporting the observed range. Realistic challenges to this positioning remain limited given the final observational data, though minor revisions could arise from quality-controlled adjustments at the primary station or if resolution relies on a secondary site (e.g., Midway) with slightly different readings. No major model discrepancies or data gaps appear in post-event summaries.

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 9 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 observations from the National Weather Service at Chicago O'Hare recorded a daily maximum of 80°F on September 9, 2026, aligning closely with the market's near-certain 78-79°F bin (99.7% implied probability).** This outcome reflected seasonal conditions moderated by cloud cover, morning showers, and a passing cold front that limited afternoon heating.
