Market context
Beijing's peak temperature on 15 August 2026 will be measured from the Capital International Airport Station's Daily Observations table on Weather Underground, with resolution determined by the highest recorded reading in Celsius rather than summary figures. The settlement window closes at midday UTC on that date, meaning the full 24-hour temperature cycle through midnight local time will inform the outcome.
August in Beijing typically sees daily highs between 26–32°C, though extremes have reached into the mid-30s during heat waves. Historical data from the past decade shows that mid-August temperatures cluster around 28–30°C on average, with only occasional spikes above 32°C. The 0% crowd probability suggests traders are pricing in either a specific temperature range expectation or uncertainty about which bracket will capture the day's maximum. Comparable August dates at the same station provide the most reliable baseline; 15 August 2023 recorded a high of 31°C, whilst 2022 peaked at 29°C.
Traders should monitor China's meteorological forecasts from late July onwards, as seasonal weather patterns and any developing heat systems will become clearer two to three weeks before the settlement date. The specific reliance on the Daily Observations table—not the Day High & Low summary—means resolution hinges on granular station data rather than rounded figures, potentially affecting outcomes at boundary temperatures. Any significant atmospheric pressure systems or unusual circulation patterns affecting northern China in early August could shift the distribution materially.

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.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- 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.
