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 9 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 9, 2026, after the highest temperature in Beijing on June 9 has been recorded and verified. Resolution depends on official temperature data for that date, typically sourced from Beijing's primary meteorological station or national weather authority records. The outcome is determined by comparing the actual recorded high temperature against the predefined thresholds embedded in each contract. Once the official data is published and confirmed, the market settles and winning positions are paid out accordingly.
Several factors could shift market odds before June 9. Seasonal weather pattern updates, tropical cyclone formation or dissipation, and atmospheric pressure anomalies in East Asia can alter temperature expectations. Long-range forecasts from meteorological agencies may revise their predictions, prompting trader repositioning. Urban heat island effects or unusual pollution events could also influence perceptions of Beijing's peak temperature. Additionally, historical temperature records for early June and real-time weather model consensus updates will likely drive trading activity as the event date approaches.
