Market context

Beijing's daily maximum temperature on 4 June 2026 will be recorded at the Capital International Airport meteorological station and resolved against historical data from Weather Underground. Early June sits within Beijing's late spring period, when daytime highs typically range between 28–32°C, though heat waves can push readings several degrees higher. The 0% crowd probability suggests traders are either absent from this market or treating the outcome as highly uncertain across all temperature bands.

Historical June temperatures at Beijing Capital Airport show considerable year-to-year variation. Between 2015 and 2024, early June maximums ranged from 24°C during cooler years to 36°C during heat events, with median values clustering around 29–31°C. The absence of any meaningful probability mass indicates the market lacks consensus on whether conditions will favour cooler spring weather or early-season heat. For programmatic traders, this represents a calibration challenge: establishing priors requires either accessing 30-year climate normals or building conditional logic that weights recent anomalies against seasonal baselines.

Monitoring China's meteorological forecasts and synoptic patterns through May 2026 will be essential. The East Asian summer monsoon's onset timing—typically occurring in early to mid-June—acts as a primary catalyst; early arrival brings moisture and cloud cover that suppresses maximum temperatures, whilst delayed onset allows high-pressure systems to dominate. Traders should track official China Meteorological Administration seasonal outlooks and real-time atmospheric indices (Pacific-Japan pattern, subtropical ridge positioning) as June approaches, since these drive whether conditions favour the cooler or warmer resolution bands.

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.
