The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Chengdu Shuangliu International Airport Station, available here: https://www.wunderground.com/history/daily/cn/chengdu/ZUUU. 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 reflect real-money bets from traders worldwide and often incorporate meteorological data, historical patterns, and seasonal trends faster than traditional analyst consensus. While weather forecasters publish point estimates and confidence intervals based on numerical models, this market aggregates dispersed trader knowledge into a single probability. Comparing the two reveals whether professional meteorologists and market participants align on the likelihood of extreme heat in Chengdu, or whether one group is pricing in risks the other underweights.
This market resolves around Jul 4, 2026, once July 4 has passed and the highest temperature recorded in Chengdu for that day is confirmed. The outcome is determined by verifying the actual peak temperature against credible public weather reporting, establishing whether it met or exceeded the 38°C threshold. Traders holding winning shares receive their payout once the result is official and the market settles.
Major weather pattern shifts, updated seasonal forecasts, and real-time atmospheric data releases can all shift odds significantly. If meteorological models begin indicating a stronger heat dome or monsoon disruption over central China, bullish traders may bid up the "yes" shares. Conversely, cooler-than-expected conditions in the weeks leading up to July 4, or a shift toward wetter patterns, could drive prices lower. Historical temperature records for the date and broader climate anomalies also influence trader conviction.
