Highest temperature in Shanghai on July 7?

Platform comparison

Market context

On 7 July 2026, the Shanghai Pudong International Airport Station will record its highest temperature for the day, a real-world event that determines the outcome of this prediction market. Today, Polymarket prices the contract with a 0% probability for the YES outcome, implying the crowd believes the temperature will fall outside the specified range. This pricing reflects the on-chain mechanics where USDC trades occur on the Polygon network using conditional tokens, locking in the market’s current consensus before the settlement window closes on 12:00 UTC.

Historical data frames this near-zero probability as a rational assessment rather than an outlier. July is Shanghai’s hottest month, with average highs reaching 87°F (30.6°C) and daily peaks rarely falling below 75°F (23.9°C) or exceeding 95°F (35°C)[1][6]. Recent forecasts for 7 July show a maximum of 33°C at 14:00, consistent with typical summer patterns where temperatures regularly exceed 30°C and reach 35°C under sunny conditions[2][7]. The crowd’s 0% stance suggests the specified range likely caps below these common thresholds, making the YES outcome improbable given the station’s documented climate.

Traders should monitor real-time weather updates from Wunderground and local meteorological announcements, as sudden shifts in cloud cover or wind could alter the peak temperature. The National Weather Service recorded 29.64°C at 04:00 on 7 July with clear skies and SSE winds, indicating stable conditions that may sustain high daytime temperatures[3][5]. While no specific weather alerts have been issued recently, the dependency on clear solar energy—gradually increasing by 0.5 kWh in July—means any unexpected cloud cover could suppress the peak[1]. Traders must watch for these variables before the settlement deadline to assess if the 0% probability holds.
