توقع: Highest temperature in Shanghai on July 31?

Platform comparison

Market context

Shanghai’s high at Pudong on 31 July is usually decided by heat rather than by a single shower, and the main question for this market is whether the day finishes in the low-to-mid 30s Celsius or pushes into the upper 30s. Current forecasts cluster around a hot, humid day: AccuWeather shows Shanghai’s July highs generally running from 86°F to 100°F, with 31 July around 91°F, while other forecast feeds put the day near 34°C to 37°C.[1][7][11][13]

That framing matters because late July is typically one of Shanghai’s hottest stretches, and 31 July is often among the clearest days of the month.[9][18] Historical July guidance puts average highs around 33°C to 34°C, with humidity remaining high and rainfall still frequent enough to trim extremes if convection develops.[12][19][20] In other words, the market’s 0% implied probability on an outsized heat outcome is only consistent if traders expect cloud cover or showers to cap the airport’s maximum well below the forecast range.

The key catalysts are the next model updates and any shift in shower timing, because the settlement source is the *highest* temperature recorded at Shanghai Pudong International Airport Station before the window closes at 12:00 UTC. Weather.com is already flagging showers and a high near 95°F, while the UK Met Office has Shanghai at 37°C with a low rain chance early in the day, showing how sensitive the cap is to small changes in cloud and precipitation timing.[11][13] For traders, the most relevant dependency is whether the airport stays on the warm side of the marine influence through the local afternoon, when Shanghai usually posts its daily maximum.

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.

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.
