Market context
Chongqing’s high temperature on 3 August will come down to whether the day follows the city’s usual late-summer heat profile or lands on the hotter end of the range. August is typically Chongqing’s hottest month, with average highs around 34°C and published August extremes in the high 30s to low 40s Celsius, so a reading well above 35°C would not be unusual in the broader climate context.[1][5][8]
The market’s current 0% YES implies traders are assigning virtually no chance to the event landing in the specified temperature band, which is difficult to reconcile with seasonal norms unless the range is very high. Comparable August climatology for Chongqing shows a typical 3 August high around 34.7°C, while the city’s all-time record reaches 43°C, indicating that the upper tail is possible but still exceptional.[1][3][15]
For traders, the key catalyst is the actual observation at Chongqing Jiangbei International Airport Station on the settlement day, because the market resolves from the Wunderground daily history for that station rather than from citywide forecasts.[2] Any short-term shift in cloud cover, rainfall, or monsoonal moisture can materially affect the day’s peak temperature, and the most relevant updates will be the final airport-area forecast revisions rather than broader Chongqing summaries.[1][8][12]

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.
- 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.
