Highest temperature in Beijing on July 23?

Platform comparison

Market context

Beijing’s temperature on 23 July will be set by the day’s peak reading at Beijing Capital International Airport, with the outcome determined by which Celsius band contains that high. The market is currently split around the upper-20s, with 28°C leading at 34% and 27°C next at 30%, which suggests traders are leaning towards a warm but not extreme afternoon rather than a sharp heat spike.[1]

That distribution is consistent with a summer forecast regime where small shifts in cloud cover, wind and the timing of convective showers can move the day’s maximum by a degree or two. In a market like this, the key historical comparator is not a single forecast point but the frequency with which Beijing’s airport reaches the high 20s in late July; that leaves 27–29°C as the most natural cluster unless a stronger hot-air mass builds in. The fact that 0% is assigned to the YES side also points to a market that is effectively waiting to see whether the eventual maximum falls into one of the listed bins rather than implying any dramatic weather break.[1]

For traders, the main catalysts are the morning and early-afternoon updates from local forecasters, any change in the airport station’s reported peak by noon UTC, and whether showers develop early enough to cap the temperature before the daily maximum is reached. The settlement source is the Wunderground history page for Beijing Capital International Airport, so the final print will depend on that station’s recorded high rather than an urban average or a citywide forecast.[1]

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.

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.

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.
