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 26 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.

Prediction market odds often diverge from traditional weather analyst forecasts because they aggregate real-time trader expectations rather than relying on a single model or institution. Analysts typically publish deterministic or probabilistic forecasts based on atmospheric data and historical patterns, while this market prices uncertainty through continuous trading. Comparing the two reveals whether the crowd expects conditions warmer or cooler than official meteorological guidance. Prediction markets can sometimes detect emerging consensus faster than traditional forecasts update, especially when new data arrives close to the event date. Both sources offer value: analysts provide detailed reasoning, while market odds reflect distributed belief across many participants.
This market resolves around Jun 26, 2026, once the highest temperature recorded in Beijing for June 26 becomes verifiable from credible public reporting. The outcome is determined by comparing the final temperature reading against the specific threshold defined in the market. Resolution occurs after the event date has passed and official meteorological data is published and confirmed. Traders holding shares in the correct outcome receive their payout once the market settles. Until that point, positions remain open and prices may continue to shift based on updated forecasts or incoming weather information.
Several factors could shift odds significantly before resolution. Updated weather models from major meteorological agencies—such as revised forecasts showing stronger or weaker heat patterns—often trigger immediate repricing. Seasonal climate anomalies or unexpected atmospheric events, like sudden pressure system changes, can alter trader expectations. Real-time temperature readings in the days leading up to June 26 provide concrete data that narrows uncertainty. Major news about air quality, pollution events, or urban heat island effects in Beijing may also influence perceptions of peak temperature. As the event date approaches, early morning and afternoon temperature reports will anchor trader confidence, driving final price convergence toward the actual outcome.
