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 15 Jun '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.Recent National Weather Service and private model consensus points to a below-normal high around 73°F in Chicago on June 15, driven by persistent northwesterly flow and increased cloud cover behind a departing frontal boundary that limits daytime heating and mixing. This setup contrasts with June climatological normals near 80°F and keeps the highest temperature most likely in the 74–77°F range, where market-implied odds are concentrated. Key variables include boundary-layer moisture, solar insolation under partial cloud decks, and any late-day clearing that could allow modest warming; updated model runs tonight will clarify whether the peak edges toward the upper or lower end of that window before resolution.
