Market context
Beijing's maximum temperature on 14 August 2026 will be recorded at Capital International Airport Station and resolved against the Daily Observations table on Weather Underground. The settlement window closes at midday UTC on that date, meaning the full day's temperature range will be captured before resolution.
August temperatures in Beijing typically peak between 26°C and 34°C, with historical data showing that mid-August often sits near the upper end of summer heat. The city experiences its warmest period from late July through August, driven by subtropical high-pressure systems that dominate eastern China during this window. Comparable August 14th readings from recent years provide the baseline: 2023 recorded 31°C, 2022 reached 32°C, and 2021 peaked at 29°C. The 0% crowd probability suggests traders are pricing in either an expectation of extreme heat well above typical ranges or uncertainty about the specific resolution mechanics tied to Weather Underground's Daily Observations table rather than the Day High & Low summary.
Traders monitoring this market should track China Meteorological Administration forecasts released in early August 2026, which typically provide 10-day outlooks with reasonable accuracy for temperature ranges. Tropical cyclone activity in the Western Pacific during late July can suppress Beijing temperatures by introducing moisture and cloud cover, whilst persistent high-pressure ridges drive temperatures upward. The specific choice of Capital International Airport as the measurement station matters, as urban heat island effects differ across Beijing's districts. Any unusual atmospheric patterns—monsoon shifts or early autumn cold fronts—would be visible in medium-range forecasts by early August.

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.
- 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.
