Highest temperature in Shanghai on August 3?

Platform comparison

Market context

Shanghai Pudong International Airport is in a typical midsummer pattern, with August forecasts clustered around the low-30s Celsius and overnight lows in the mid-to-high 20s. AccuWeather’s monthly outlook puts Shanghai’s August daily highs between 82°F and 92°F, while other forecasts for early August show peaks around 33°C to 35°C and warm, humid conditions through the day.[1][3][5][6]

That backdrop makes a sub-30°C result look unlikely unless cloud, rain or a sea-breeze shift meaningfully caps the daytime high. Shanghai’s August climate is normally hot and humid, with travel and weather guides pointing to average highs near 32°C and typhoon-season rainfall in the month, which can suppress the extreme if showers arrive during the warmest hours.[12] The market’s 0% implied YES price is therefore consistent with the broader forecast range, but the exact settlement hinges on the airport station’s recorded daily maximum, not the citywide headline forecast.[1][12]

Traders should watch for any last-minute convection, thunderstorm or rain-band timing around the airport, because that is the main pathway to a lower-than-expected maximum. Forecast sources currently show mostly warm, partly cloudy or light-rain conditions rather than a sharp cool spell, and the main live variable is whether precipitation develops during the afternoon heating peak.[6][10][14] Because the market resolves from Wunderground’s Shanghai Pudong International Airport Station history page, the only outcome that matters is the highest temperature logged there before the settlement window closes.[10]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

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.
