Market context
Beijing's highest temperature on 15 August 2026 will be measured at the Capital International Airport Station and resolved using Weather Underground's Daily Observations table rather than summary figures. The settlement window closes at midday UTC on that date, meaning the full day's temperature record will be available before resolution.
August temperatures in Beijing typically peak between 32–35°C, with occasional extremes reaching 37–38°C during heat waves. Historical data from the past decade shows that mid-August readings at the airport station rarely exceed 36°C, though the 2010 heat wave produced readings above 40°C across the city. The 0% crowd probability suggests traders are either uncertain about the specific temperature bands offered or expect relatively moderate conditions. Comparable August 15th readings from 2015–2023 cluster in the 33–35°C range, providing a baseline for assessing whether the market's current odds reflect typical seasonal patterns or an outlier expectation.
Traders should monitor seasonal forecasts released in July 2026 and any El Niño or La Niña patterns that could influence East Asian summer temperatures. China's meteorological service typically issues detailed August forecasts by late June. The specific resolution methodology—relying on the Daily Observations table rather than headline figures—matters operationally; discrepancies between the two sources have historically occurred during rapid temperature swings or equipment recalibration events. Weather Underground's data feed for Beijing Capital Airport has remained consistent, though traders should verify the station identifier remains unchanged closer to the settlement date.

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.
- 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.
- 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.
