Highest temperature in Shanghai on July 14?

Platform comparison

Market context

Shanghai's summer temperatures peak in July, with daily highs typically ranging between 32–35°C during mid-month. On 14 July 2026, the settlement will depend on the single highest temperature recorded at Pudong International Airport's official weather station throughout that calendar day. The 0% crowd probability suggests traders are either uncertain about the resolution mechanics or treating this as a calibration exercise rather than a genuine forecast. Wunderground's historical data for this station provides granular hourly readings, making automated monitoring straightforward for conditional order systems or bot-based tracking.

Shanghai's July climate follows predictable patterns shaped by the East Asian summer monsoon and occasional tropical systems. Historical records from the past decade show daily highs in mid-July cluster around 33–34°C under typical conditions, though heat waves can push readings above 37°C. The 2013 heat wave saw Shanghai record 40.6°C in August, establishing the upper boundary for plausible July outcomes. For programmatic traders, the relevant catalyst is the China Meteorological Administration's 10-day forecast issued around 5 July, which typically signals whether monsoon patterns or high-pressure systems will dominate the settlement window.

Traders evaluating this market should note that Wunderground's Shanghai Pudong station data updates daily and remains accessible via API for automated polling. The settlement window closes at 12:00 UTC on 14 July, allowing approximately 12 hours of the calendar day to remain unresolved—relevant for traders using conditional orders triggered by morning forecasts. Temperature ranges in comparable markets typically span 1–2°C intervals, making the specific bracket selection critical for position sizing.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
