"Highest temperature in Chicago on May 29?" is a weather prediction market focused on the maximum temperature recorded at Chicago O'Hare Intl Airport Station on May 29, 2026. The event resolves to the temperature range containing the day’s highest observed reading, using Wunderground’s daily history page as the resolution source. Because the market relies on a single official station and whole-degree Fahrenheit data, traders are forecasting one specific expected outcome: which temperature band will capture Chicago’s hottest point on that date. The market opens on May 27, 2026 and is scheduled to end on May 29, 2026, with final resolution only possible after the first data point for the following day is published. As a recurring weather event, it is useful for tracking market sentiment around late-May conditions in Chicago. Current probability data is not provided here, so the listed odds should be interpreted from trading activity and market prices rather than a published forecast.
