Highest temperature in Beijing on July 16?

Platform comparison

Market context

The market tracks the peak Celsius reading at Beijing Capital International Airport on 16 July 2026, resolving via Wunderground history. With the settlement window closing at noon UTC, the current 0% YES crowd-implied probability for any specific outcome is a misreading of the binary interface; the actual frontrunner is 33°C at 39%, followed by 34°C at 27%[1]. This distribution aligns with July’s typical warm, humid climate where temperatures usually span 23°C to 31°C, though heatwaves frequently push readings higher[2]. Programmatic traders should note that the 0% figure likely reflects a UI quirk or a specific binary condition not yet triggered, rather than a genuine belief that no temperature will occur.

Historically, Beijing’s July is one of its wettest months, averaging 185 mm of rainfall and over ten rainy days, which often suppresses peak temperatures despite the heat[2][3]. A trader building a script to monitor this market must watch the daily Wunderground feed for the specific station ZBAA, as cloud cover and precipitation from the monsoon season can create volatility around the 33–34°C range. The catalyst to watch is the real-time weather feed itself; there are no human announcements or economic schedules, only the atmospheric dependency on the monsoon system which concentrates over 50% of the annual rainfall in July and August[3]. Automated bots should poll the resolution source every hour to capture the daily maximum before the 12:00 UTC cutoff.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
