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 2 May '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.Latest National Weather Service forecasts and GFS model runs indicate Chicago's high temperature on May 2 will likely peak in the mid-50s°F at O'Hare International Airport, the market's resolution station, due to a cold front's recent passage introducing cooler Canadian air masses, persistent low-level clouds, and scattered shower risks that limit solar heating. This positions 54°F or higher at 42% trader consensus, reflecting ensemble spread allowing partial clearing for upper 50s, while 52-53°F at 27% captures downside from added precipitation in the past day's 12Z GFS update. Lake Michigan's cooling influence adds variability amid a warmer-than-average spring outlook; new 00Z model cycles and NWS advisories today could refine probabilities before resolution.
