Market context

On 4 June 2026, Beijing's highest temperature will be recorded at Capital International Airport Station and measured in Celsius. Polymarket currently prices this contract at 0% YES, meaning traders are assigning negligible probability to any outcome materialising. The settlement hinges on Wunderground's historical weather data for that specific station, with the conditional token structure on Polygon allowing traders to hold positions in USDC-denominated ranges until the settlement window closes at 12:00 UTC on the resolution date.

Beijing's June climate sits firmly in early summer, with historical highs typically ranging between 28°C and 33°C during the first week of the month. Data from the past decade shows 4 June temperatures clustering around 30–32°C on most years, with occasional spikes to 34°C during warmer seasons. The 0% crowd probability suggests either extreme confidence in a specific temperature band or minimal trading activity in this particular contract, making it difficult to discern genuine market conviction from thin liquidity.

Traders monitoring this market should track China Meteorological Administration forecasts released in late May 2026, which will provide the most reliable 10-day outlook for Beijing. Atmospheric patterns in early June depend heavily on whether subtropical high-pressure systems have established themselves over northern China—a development typically signalled by late-May weather bulletins. Any unusual heat waves or cold fronts affecting East Asia in the weeks prior would merit attention, though such events remain inherently difficult to predict beyond a fortnight in advance.

Resolution & payout

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
