Market context
Beijing's highest temperature on 16 August 2026 will be measured at Capital International Airport Station and resolved against the Daily Observations table on Weather Underground, with the settlement window closing at midday UTC on that date. The specific temperature reading will determine which range bracket resolves affirmatively.
August in Beijing typically sees peak summer heat, with historical highs regularly exceeding 35°C during mid-month. Data from the past decade shows 16 August highs ranging between 32–37°C, with 2015 recording 36.8°C and 2019 reaching 35.5°C. The 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a placeholder market pending meteorological updates closer to the resolution date. Comparable August dates at the same station have produced consistent patterns: afternoon peaks driven by continental air masses, with occasional moderation from convective activity.
The critical variable for traders will be long-range weather models released in late July and early August 2026, particularly from the China Meteorological Administration and international forecast services. Anomalous heat patterns or monsoon influences affecting northern China could shift outcomes materially. The resolution mechanism's reliance on the Daily Observations table rather than summary figures introduces a technical dependency—traders should verify historical consistency between these two Weather Underground data sources at Beijing Capital International Airport to understand potential discrepancies that might affect settlement interpretation.

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.
- 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.
