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 10 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 10, 2026, after the highest temperature in Paris on June 10 has been recorded and verified. Resolution is determined by official temperature data for that date, ensuring an objective, measurable outcome. Once the peak temperature is confirmed, the corresponding outcome contract settles to 100 cents and all other contracts settle to zero, distributing winnings to holders of the correct outcome and concluding trading on this event.
Major weather pattern shifts, including changes to jet stream positioning or high-pressure systems over Western Europe, could significantly move odds. Updated seasonal forecasts from meteorological agencies and real-time weather model runs in the days leading up to June 10 will influence trader positioning. Urban heat events, cloud cover patterns, and atmospheric circulation anomalies specific to early June could all trigger repricing. As the event date approaches, increasingly accurate short-range forecasts will narrow uncertainty and drive final market convergence toward the realized temperature outcome.
