Market context

Shanghai's weather on 10 June 2026 will be measured against historical temperature records for that specific date at Pudong International Airport, the city's primary meteorological observation point. Early summer in Shanghai typically brings warm, humid conditions as the East Asian monsoon intensifies, with June temperatures regularly exceeding 30°C. The settlement mechanism relies on Wunderground's historical weather database, which aggregates official station data and resolves to the single highest reading recorded across all daylight and evening hours on that date.

June temperature patterns in Shanghai show considerable year-to-year variation depending on monsoon timing and tropical system activity. Over the past decade, 10 June highs have ranged from approximately 26°C to 35°C, with an average around 30–31°C. Unusually cool readings occur when frontal systems or early-season rainfall suppress daytime maxima, whilst heat waves—occasionally driven by subtropical high-pressure systems—can push temperatures into the mid-to-upper 30s. The 0% crowd probability suggests traders are pricing in either extreme confidence in a specific temperature band or insufficient liquidity to establish meaningful odds across the full range of plausible outcomes.

Key variables affecting the settlement outcome include the strength and positioning of the Pacific subtropical high-pressure system in early June, potential tropical cyclone activity in the western Pacific, and any lingering spring rainfall patterns. Long-range seasonal forecasts from China's meteorological authority, typically released in May, will provide initial guidance on monsoon onset timing. Real-time monitoring of upper-atmosphere patterns and sea-surface temperatures in the weeks preceding the event will sharpen expectations around whether June 10 falls within a cooler, wetter phase or a drier, hotter interlude.

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.
