Market context
Chongqing’s temperature on 27 July will be set by the highest reading at Chongqing Jiangbei International Airport Station, with the market currently pricing a hot afternoon: 39°C leads at 42%, ahead of 38°C at 31%. July is normally one of Chongqing’s hottest, stickiest months, with average highs around 33°C, high humidity and frequent rain, so any clear, sunny spell can push the day’s maximum well above the monthly mean.[1][2]
The 0% YES crowd price sits below the climate profile that usually governs this market, but it is still only one day’s airport observation that matters. Chongqing’s July weather is shaped by a subtropical monsoon pattern, with most of the annual rain falling from May to September and frequent thunderstorms interrupting heat build-ups; that makes the upper end of the temperature range more dependent on cloud cover, rainfall timing and whether the hottest part of the day is reached before convective showers arrive.[2][3]
For traders, the key catalysts are the airport’s daytime weather evolution, any short-range forecast changes, and the timing of showers or storm clusters relative to the midday-to-afternoon heating window. Travel guidance for July consistently describes Chongqing as extremely hot and rainy, with heavy thunderstorms appearing several times in the month, which is the kind of setup that can cap the day near 33–35°C or allow a spike into the upper 30s if rain holds off.[2][4]

FAQ
- 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.
- 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.
- 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.
