Highest temperature in Beijing on July 23?

Platform comparison

Market context

Beijing’s heat on 23 July will be decided by the day’s peak reading at Beijing Capital International Airport Station, so the market is really about how far the city can climb before afternoon cloud cover, rain, or a sea-breeze influence caps the temperature. The current crowd split is concentrated around the high-20s, with 28°C leading at 34% and 27°C close behind at 30%, which suggests traders are not pricing in an extreme heat spike for the airport station.[1]

The 0% price on the top-end outcome is best read as a statement about the distribution, not a forecast of certainty: when a market is tightly clustered in the upper-20s, any small change in the late-day weather pattern can still shift the result by a degree or two. For a comparable frame, airport-based summer temperature settlements in Beijing often hinge on whether the warmest reading arrives before convection builds in the afternoon, rather than on the daily mean or the official city forecast.[1]

For traders, the main catalysts are the morning and early-afternoon forecast updates, any thunderstorm or shower risk for the capital region, and how quickly the temperature rises at the airport station relative to nearby districts. The settlement source is Wunderground’s daily history page for ZBAA, so the key dependency is the station’s recorded maximum rather than a headline forecast for central Beijing.[1]

FAQ

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?

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.
