Highest temperature in Shanghai on July 5?

Platform comparison

Market context

On 5 July 2026, the Shanghai Pudong International Airport Station will record its peak temperature for the day, a metric that determines the outcome of a prediction market currently implying zero probability for the highest temperature falling within the lowest range. Historical data confirms that July is Shanghai’s hottest month, with average highs reaching 87°F (30.5°C) and frequent peaks exceeding 95°F (35°C) during sunny spells[1][7]. The lowest temperature range in question is statistically incompatible with midsummer conditions at this coastal airport, where daily highs rarely dip below 75°F (24°C) even on cooler days[1].

Traders should monitor incoming severe thunderstorm clusters and precipitation forecasts, which could temporarily suppress temperatures but not to the extent of validating the lowest range[2][3]. Recent reports from the National Weather Service indicate numerous temperature records are expected alongside clusters of severe thunderstorms, suggesting volatile but still warm conditions[3]. While BBC Weather notes thundery showers for nearby Hongqiao Airport with highs of 29°C, Pudong’s maritime exposure typically sustains higher baseline temperatures[4][6]. The divergence between sportsbook lines (if any exist for weather derivatives) and the current 0% implied probability reflects a consensus that extreme cold is impossible in this context, aligning with analyst expectations of summer heat dominance.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Best Prediction Markets UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
