Market context

Beijing's highest temperature on 15 June 2026 will be measured at Capital International Airport Station and resolved against historical records from Wunderground. The market currently shows 0% implied probability across all temperature ranges, reflecting either a data lag or settlement mechanics that haven't yet populated active trading. June in Beijing typically brings early summer conditions with highs between 28–32°C, though heat waves can push readings into the mid-30s. The settlement window closes at midday UTC on the event date, giving traders a narrow window to adjust positions after morning temperature readings become available.

Historical June temperatures at Beijing Capital Airport reveal a consistent pattern: the past decade has seen highs ranging from 26°C in cooler years to 37°C during exceptional heat events. The 2020 heatwave pushed June maximums above 35°C on multiple days, whilst 2019 and 2021 remained closer to seasonal norms around 30–31°C. This variance suggests the market's current flat probability distribution may underweight tail outcomes. Traders should note that June 15 falls before Beijing's peak summer heat, typically concentrated in July and August, which historically constrains extreme readings.

Monitoring China's meteorological forecasts and regional weather patterns through early June will be essential. The East Asian summer monsoon's timing and intensity directly influence Beijing's temperature trajectory, and any official heat warnings from the China Meteorological Administration would signal elevated probabilities for ranges above 32°C. Wunderground's historical data feed remains the binding resolution source, so traders should verify the station's operational status ahead of settlement.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
