Market context

Shanghai’s maximum on 9 August will be driven by a familiar late-summer mix of heat, humidity and rain risk, with the market settling on the **highest temperature recorded at Shanghai Pudong International Airport Station** rather than the headline daily high. The broad forecast range for the day is clustered in the high 20s to mid 30s Celsius depending on source: AccuWeather’s August outlook shows Shanghai daily highs between **84°F and 94°F** for the month, while several day-specific forecasts for 9 August point to a cooler, wetter outcome, including **29°C** on weather.com.cn and **28°C** on PredictWind[1][12][4].

That leaves the current **0% yes** price looking more like a function of the market not yet reflecting the eventual station observation than a meaningful read on climatology. Comparable August Shanghai readings often sit in the low 30s Celsius, but the city is also prone to sharp cloud, rain and thunderstorm interference that can cap the day’s top figure well below the monthly average. Weather2Travel pegs typical August daytime maxima around **31°C**, and WeatherSpark notes daily highs generally sit near **90°F to 85°F** through the month, rarely breaking **96°F**[14][18].

The key catalyst is the evolution of the short-range forecast between now and settlement, especially the timing and intensity of rainfall around Pudong. AccuWeather currently shows **97% precipitation probability** for 9 August, with wind and periods of rain expected, while worldweatheronline and weather.com.cn both point to heavy rain and strong easterly or north-easterly flow[5][11][12]. For this market, the important dependency is not whether Shanghai feels hot overall, but whether breaks in cloud cover allow a brief spike at Pudong before rain and maritime air suppress the station high.

FAQ

When do sports markets resolve?
Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
Can I bet on individual matches?
Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
Which sports markets are available?
Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
What's the difference between match odds and outright odds?
Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
Can I import form data and lineups?
This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
