Highest temperature in Shanghai on August 5?

Platform comparison

Market context

Shanghai’s reading at Pudong airport is being set against a very hot late-summer baseline, with August forecasts and climatology clustering around the low-to-mid 30s Celsius and only modest day-to-day variation. AccuWeather’s August outlook shows Shanghai daily highs mostly between 82°F and 92°F (about 28°C to 33°C), while several other forecast sources put 5 August near 34°C to 35°C, which is the same band implied by the market’s leading outcomes and helps explain why 0% for “YES” looks detached from the weather setup rather than signalling any confirmed miss.[1][3][4][10]

For traders, the main catalyst is whether afternoon heating is checked by cloud, showers or a thunderstorm window, because that can move the day’s peak a degree or two either side of the most common forecast cluster. Recent guidance points to patchy rain potential and high humidity, with one outlook showing 35°C / 26°C and another 34°C with a very high UV index, while model-style pages also leave room for a lower high if cloud or precipitation arrives early enough.[2][3][9] With the market resolving off the highest temperature recorded for the day at Shanghai Pudong International Airport Station, the key watchpoint is the official daily history update from Wunderground rather than the citywide forecast headline, since the airport can diverge from central Shanghai on wind, cloud and timing of convective showers.[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.

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.
