Highest temperature in Beijing on June 16?

Market context

Beijing's peak temperature on 16 June 2026 will be recorded at Capital International Airport Station and resolved against historical weather data. The current crowd-implied probability of 0% YES suggests traders are pricing this as a near-certain outcome falling outside the specified range, though the settlement window closes at midday UTC on that date, potentially capturing only partial daily temperature data depending on local observation schedules.

Mid-June in Beijing typically sees maximum temperatures between 28°C and 33°C, with occasional peaks above 35°C during heat waves. Historical data from Wunderground shows June 2023 recorded highs of 32–34°C across multiple days, whilst June 2024 saw similar patterns with occasional excursions to 35°C. The 0% probability reading suggests the market's range options may be positioned at extremes—either unusually low thresholds or exceptionally high ones—making the current odds less informative about actual temperature likelihood than about how the resolution brackets are structured.

Traders should monitor China Meteorological Administration forecasts released in early June 2026, which typically provide 10-day outlooks with reasonable accuracy for seasonal patterns. Any significant atmospheric pressure systems or heat dome formations affecting northern China in that period would shift expectations materially. The settlement dependency on Wunderground's specific station data means localised microclimatic factors at the airport site matter; urban heat island effects and airport infrastructure can produce readings 1–2°C higher than surrounding areas. Real-time weather model consensus from major forecasters will become actionable only days before the event.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
