Market context
Chengdu’s highest temperature on 3 August will be set by the airport station reading, so the key question is whether the day reaches the sort of mid-30s heat that is normal in August rather than an outlier spike. Seasonal guides put Chengdu’s August highs around 30–34°C, with humid, rain-prone conditions but frequent short-lived showers rather than all-day washouts.[1][3][10][16] Forecasts available for 3 August have already pointed to a hot day, with several outlooks showing around 33°C and sunny or mostly sunny conditions.[2][4][5][13]
For context, Chengdu’s August temperatures commonly sit in the low 30s, and some guides note that highs can still push beyond 35°C on hotter days, especially in and around the city.[1][3][10][14] That leaves the market’s 0% implied YES price looking tied to a very specific temperature band outcome rather than a broad weather regime. In practical terms, the settlement is likely to hinge on whether afternoon heating at Chengdu Shuangliu International Airport is capped by cloud or rain, or whether sunshine allows a clean run into the mid-30s, which is consistent with recent point forecasts.[2][15][17]
Traders should watch the airport-specific observations and any updated same-day forecast from the resolution source, because the market resolves to the highest recorded temperature at Chengdu Shuangliu International Airport Station on 3 August, not the city average.[17] The main catalysts are the timing of morning cloud cover, any afternoon thunderstorm risk, and whether the forecasted 33–35°C range is revised up or down as the day develops.[2][15][19]

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.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- 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.
