توقع: Highest temperature in Shanghai on August 17?

Platform comparison

Market context

Shanghai's highest temperature on 17 August 2026 will be measured at Pudong International Airport Station and resolved against the Daily Observations table on Weather Underground, with settlement occurring at midday UTC on that date. The market currently reflects zero probability across all temperature bands, suggesting either extreme uncertainty or insufficient trader participation in this specific weather outcome.

August represents peak summer in Shanghai, with historical daily highs typically ranging between 32–35°C during mid-month. The city's subtropical climate produces consistent heat through the month, though occasional tropical systems can elevate temperatures or introduce cloud cover that moderates peaks. Comparable August 17 observations from prior years show the highest temperatures clustering in the 33–34°C range, with extremes occasionally reaching 36°C during particularly intense heat waves. The 0% crowd probability may reflect the market's early stage rather than genuine conviction about temperature bounds.

Traders should monitor tropical cyclone forecasts issued by the China Meteorological Administration in the weeks preceding mid-August, as these systems significantly influence Shanghai's weather patterns and can either suppress temperatures through cloud cover or drive them higher through atmospheric pressure dynamics. The East Asian summer monsoon's strength in early-to-mid August also affects moisture levels and convective activity. Real-time weather models from major forecasters will become increasingly reliable within two weeks of the settlement date, allowing traders to refine positioning as the actual atmospheric setup becomes clearer.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.
