This market will resolve to the temperature range that contains the highest temperature recorded at the Beijing Capital International 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 Beijing Capital International Airport Station, available here: https://www.wunderground.com/history/daily/cn/beijing/ZBAA. 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 recorded in Beijing on June 10 is officially reported. The outcome is determined by the maximum temperature reading for that calendar day, typically sourced from Beijing's meteorological authority or recognized weather station data. Once the official high temperature is confirmed and published, the corresponding outcome contract is marked correct, and all other contracts resolve to zero. Traders holding shares in the winning outcome receive their payout based on the final price.
Several factors can shift odds for Beijing's June 10 high temperature. Major weather pattern changes—such as the arrival of cold fronts, monsoon systems, or heat waves—will trigger repricing as updated forecasts become available. Seasonal climate anomalies, including El Niño or La Niña effects, influence regional temperatures weeks in advance. Real-time atmospheric data releases and model consensus updates typically move markets significantly. Historical temperature records for that date and recent Beijing heat trends also inform trader positioning. As June 10 approaches, short-range forecasts become more precise, often causing sharper odds adjustments in the final days before resolution.
