This market will resolve to the temperature range that contains the highest temperature recorded at the Paris-Le Bourget Airport Station in degrees Celsius on 3 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 Paris-Le Bourget Airport Station, available here: https://www.wunderground.com/history/daily/fr/bonneuil-en-france/LFPB. 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 Celsius (eg, 9°C). 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.
The market resolves on Jun 3, 2026, after the highest temperature in Paris on June 3 has been recorded and verified. Resolution is determined by official temperature data for that date, ensuring an objective, auditable outcome. Once the actual high temperature is confirmed, the corresponding outcome contract settles to 1 and all other contracts settle to 0, distributing winnings to holders of the correct outcome.
Major weather pattern shifts, updated seasonal forecasts, and atmospheric pressure systems tracking toward Western Europe could significantly move odds. Heat waves or cold fronts developing weeks in advance often trigger repricing as meteorological models gain confidence. Real-time weather updates in late May and early June will drive the most volatile moves. Additionally, historical temperature anomalies for early June and any unusual solar or oceanic activity affecting European weather patterns may influence trader positioning as June 3 approaches.
