توقع: Highest temperature in Shanghai on July 18?

Platform comparison

Market context

Shanghai's weather in mid-July typically sits in the high 30s Celsius, with the city's summer monsoon season in full swing. The settlement window closes at midday on 18 July 2026, capturing the peak heating hours when maximum temperatures are recorded. Historical data from Shanghai Pudong International Airport shows July averages around 32–35°C, though heat waves can push readings into the 37–40°C range. The 0% crowd probability suggests traders are either uncertain about the specific temperature bands available or expect conditions below historical norms for this period.

Comparable July days at Shanghai Pudong over the past decade reveal considerable variance. In 2013, the station recorded 38.9°C on 13 July during an intense heat event; conversely, cooler Julys have seen maximum temperatures settle around 31–32°C when tropical systems bring cloud cover and rain. The settlement mechanism depends entirely on Wunderground's historical records for the airport station, which maintains consistent measurement protocols. Traders should monitor early-July weather patterns in late June, as established heat domes or incoming monsoon troughs will signal the likely temperature trajectory by mid-month. Shanghai's urban heat island effect means airport readings typically run 1–2°C cooler than central city measurements.

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.
