Market context
Shanghai's highest temperature on 14 July 2026 will be measured at Pudong International Airport Station and resolved against historical weather records from Wunderground. The settlement window closes at midday UTC on that date, meaning traders will have limited time after the calendar day ends to assess final readings.
July sits within Shanghai's peak summer season, when daily highs routinely exceed 32°C. Historical data from the past decade shows that mid-July temperatures at Pudong typically range between 32–36°C, with occasional spikes above 37°C during heat waves. The 0% crowd probability suggests either extreme confidence in a specific temperature band or minimal trading activity in this market. Comparable July days at the same station provide the most reliable benchmark; weather patterns in the Yangtze River Delta region show consistency year-on-year, though individual days can deviate significantly based on cloud cover and wind patterns.
Traders should monitor Shanghai meteorological forecasts released in early July, particularly any alerts from the China Meteorological Administration regarding heat waves or unusual pressure systems. The East Asian summer monsoon's strength during that week will influence whether temperatures trend toward the seasonal average or spike higher. Wunderground's historical data feed occasionally experiences minor delays in updating final readings, so confirmation of the exact highest temperature may take several hours after the settlement window opens. Local news outlets typically report significant temperature anomalies, which can serve as cross-reference points for the official airport station measurement.

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.
- 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.
- 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.
