Pronóstico: Highest temperature in Shanghai on July 28?

Platform comparison

Market context

Shanghai's peak temperature on 28 July 2026 will be measured at Pudong International Airport Station, the city's primary meteorological observation point. July is Shanghai's hottest month, with historical daily maxima typically ranging from 32 to 35 degrees Celsius, though extremes have occasionally exceeded 37 degrees. The 0% crowd probability suggests traders expect the settlement range to fall outside the highest temperature bracket offered, likely because the specific threshold hasn't been disclosed or because the market structure creates misaligned incentives.

Shanghai's summer climate is shaped by the East Asian monsoon and urban heat island effects. The city recorded 40.9 degrees Celsius in July 2022, one of its highest temperatures on record, demonstrating that extreme heat is plausible during this period. Historical data from Wunderground shows considerable year-to-year variation; some July 28ths have peaked near 30 degrees whilst others have approached 36 degrees. The settlement window closes at noon UTC on 28 July 2026, which is 20:00 local Shanghai time, capturing the full diurnal heating cycle.

Traders should monitor long-range weather forecasts from mid-July onwards, particularly atmospheric pressure patterns and tropical cyclone activity in the Western Pacific, which can suppress temperatures through cloud cover and precipitation. El Niño or La Niña conditions may influence seasonal temperature anomalies. The specific temperature brackets offered in this market will determine whether the 0% probability reflects genuine expectations or structural issues with the range definitions; clarification of the exact settlement thresholds is essential before committing capital.

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.

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.
