Highest temperature in Beijing on July 9?

Platform comparison

Market context

The market tracks the peak temperature recorded at Beijing Capital International Airport on 9 July 2026, with the current crowd assigning zero probability to any outcome above the lowest range. This near-total dismissal of higher temperatures contradicts the region’s typical midsummer behaviour, where July regularly delivers highs around 30°C and frequently spikes well beyond that on the hottest days. Historical data confirms July is Beijing’s warmest month, with an average high of 87°F (30.6°C) and occasional peaks reaching 40°C, as seen just days earlier when the southern suburb observatory recorded 40.1°C on 6 July.

Traders should monitor Wunderground’s real-time updates for the airport station, particularly any sudden shifts in cloud cover, wind direction, or humidity that could suppress or amplify the peak. The forecast for July 2026 already indicates daily highs between 84°F and 91°F (29°C–33°C), suggesting the zero-probability stance is likely mispriced unless an unprecedented cooling event materialises. No official weather advisories have been issued yet, but any announcement from the Beijing Meteorological Bureau regarding heatwaves or rain would act as a direct catalyst for price movement. Given the recent 40.1°C reading and the airport’s proximity to the city, the market’s current form appears detached from recent results.

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.

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.

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.
