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 11 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Chicago O'Hare Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Observed temperatures at Chicago O'Hare International Airport—the official National Weather Service recording station—have already surpassed 46°F, reaching 54°F in recent hours under mostly cloudy skies and light east winds, driving Polymarket traders to a unanimous 100% implied probability for 46°F or higher as the day's high. NOAA forecasts confirm a peak near 57°F this afternoon, matching the April 11 climatological normal of 57.2°F and supported by model consensus showing stable atmospheric conditions with no cold fronts imminent. Inherent forecast uncertainty remains minimal post-threshold breach, as automated surface observing system data from redundant sensors minimizes revision risk; only an extraordinary measurement error could challenge resolution upon daily summary release.
