This market will resolve to the temperature range that contains the highest temperature recorded at the Shenzhen Bao'an International Airport Station in degrees Celsius on 11 Jul '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 Shenzhen Bao'an International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shenzhen/ZGSZ. 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 decentralized trader consensus and often incorporate real-time weather model updates, satellite data, and seasonal patterns faster than traditional analyst forecasts. While meteorologists publish point estimates and confidence intervals based on numerical weather prediction systems, this market prices in the collective judgment of participants with financial incentives to forecast accurately. Comparing the implied probability here to published forecasts from regional weather services can reveal where the crowd sees upside or downside risk relative to expert consensus, though both approaches ultimately depend on the same underlying atmospheric conditions.
On Polymarket, traders set the odds by buying and selling outcome shares in an automated market maker (AMM) system. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract represents a specific temperature range, and the price of a share reflects the probability that outcome will occur. As more traders bet on higher or lower temperatures, the market price adjusts in real time, creating a continuous price discovery mechanism. Liquidity and trading volume directly influence how tight the spreads are and how quickly prices respond to new weather information or model updates.
This market resolves around Jul 11, 2026, once the highest temperature recorded in Shenzhen on July 11 is verified against credible public sources. The outcome is determined by comparing the official temperature reading to the predefined ranges offered in the market. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. Resolution typically occurs within hours of the close of the trading day, pending confirmation from reliable meteorological or municipal data.
Major weather pattern shifts, updated seasonal forecasts, and tropical cyclone activity in the region could significantly move prices in this market. Real-time atmospheric pressure changes, monsoon intensity reports, and heat dome formation over southern China are key catalysts traders monitor. Additionally, historical temperature anomalies and urban heat island effects specific to Shenzhen's geography influence expectations. As July 11 approaches, each new weather model run and satellite observation can trigger repricing, especially if predictions diverge sharply from earlier consensus or if extreme heat warnings are issued by regional authorities.
