Highest temperature in Shanghai on August 1?

Platform comparison

Market context

Shanghai is in its hottest part of the year, and the relevant figure for settlement is the day’s **peak temperature at Pudong Airport**, not the city-wide average. August climatology for Shanghai typically sits around 31–32°C for daytime highs, with common August highs in the upper 20s to mid-30s Celsius and occasional heatwave spikes much higher, so the market only needs one strong afternoon burst to land in a higher band.[1][2][5][8]

That history matters because Shanghai has a genuine summer heat ceiling: recent and historical data show August highs of 35°C-plus are not unusual, and extreme events can go far beyond that, with Shanghai’s all-time high at 41°C and August records in the 40°C area.[3][5][7][15] By contrast, the current crowd-implied 0% for YES suggests the market is treating the upper temperature bands as very unlikely, even though late-summer heat and humidity regularly keep the door open to a materially hot reading.[1][4][9]

For traders, the main catalysts are the short-range forecast updates, the strength and timing of any heat advisory, and whether cloud, rainfall, or coastal airflow cap the afternoon maximum at the airport station rather than in central Shanghai. AccuWeather’s August 2026 outlook has daily highs broadly between 82°F and 92°F, which points to a warm but not exceptional baseline, while August in Shanghai is also typhoon-prone, so a change in wind direction or a rain band passing through before the settlement cut-off could suppress the final high.[11][9][15]

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.
