Highest temperature in Beijing on August 6?

Platform comparison

Market context

Polymarket is currently pricing this Beijing airport heat contract at **0% YES**, which means the market is assigning no weight to a top reading landing in the relevant temperature band before settlement. On Polymarket, users post and trade **USDC** on **Polygon**, with outcomes represented by conditional tokens, so the price reflects the crowd’s view of the airport station’s highest recorded temperature on 6 August rather than a generic city forecast.

For context, Beijing in August is typically hot, with published guides putting average daytime highs around **30°C to 31°C** and noting that **35°C** heat can still appear in the first half of the month. Forecasts for early August 2026 have also shown highs in the low-to-mid 30s Celsius, while official city weather notices around 5 August put Beijing at **36°C** for the next day, which is consistent with a summer pattern where a single hot afternoon can determine these range markets.

A trader watching this market should focus on the airport-specific daily maximum, not just the city forecast, because the market resolves from the **Beijing Capital International Airport Station** reading on Wunderground. The key inputs are the day’s realised sunshine, cloud cover, rain, and any late-afternoon convective burst that can cap or lift the maximum; current regional forecasts still point to hot conditions and only intermittent rain risk, which leaves room for a high single-day peak even when the broader monthly climate is mixed.

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
