Highest temperature in Shanghai on July 10?

Platform comparison

Market context

On 10 July 2026, the Shanghai Pudong International Airport Station will record its peak temperature for the day, a metric that determines the outcome of this prediction market. The current crowd-implied probability sits at 0% for the YES outcome, suggesting the consensus believes the temperature will not reach the specified threshold. However, historical data frames this as a stark underdog position; July is consistently Shanghai’s hottest month, with average highs of 87°F (30.6°C) and frequent peaks exceeding 95°F (35°C) during sunny spells [2][5]. Recent forecasts for July 2026 indicate daily highs ranging from 86°F to 97°F (30°C to 36°C), making a 0% probability appear statistically misaligned with the region’s typical summer volatility [1].

Traders should monitor the immediate weather catalysts, specifically the 40% risk of thunderstorms forecast for Friday, 10 July, which could suppress peak temperatures through cloud cover and precipitation [6]. While thunderstorms are a known dependency that often lowers maximum readings, the underlying heat index remains high, with heat indices reaching 99°F (37°C) recorded just prior to this date [9]. The value spot likely lies in contrarian angles betting against the 0% consensus, as the baseline climate regularly exceeds 30°C (86°F) [5]. A recent weather network update confirms partly cloudy conditions with a 31°F (31°C) high expected, suggesting the threshold may still be breached despite the storm risk [6]. The handicapper’s note is clear: the consensus is overly bearish on a month defined by extreme heat, and the value sits in challenging the zero probability given the robust historical precedent for temperatures well above 30°C [2][5].

FAQ

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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 Who Will Win 2026 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.
