Highest temperature in Shanghai on July 10?

Platform comparison

Market context

The real-world event at stake is the peak temperature recorded on 10 July 2026 at Shanghai Pudong International Airport, a date historically prone to extreme heat in the region. Current crowd-implied probability of 0% for a "YES" outcome suggests the market expects the temperature to fall outside the specific range being traded, likely due to prevailing forecasts indicating highs between 32°C and 35°C, which aligns with typical July conditions where daytime temperatures often exceed 30°C and frequently breach 35°C [1][4].

Historical data frames this probability sharply; July 28 is typically the hottest day, with temperatures ranging from 26°C to 31°C, yet early July averages highs near 29.8°C, rising to 30.7°C by mid-month [2][8]. Recent comparable cases show that while 26°C or below is rare (under 1% volume), the 28°C to 30°C bands attract significant trading interest, indicating the market views the current 0% probability as a mispricing if the actual temperature lands in the mid-30s range [9].

Traders must monitor the Wunderground resolution source for the official daily high, alongside any sudden shifts in shortwave solar energy, which is gradually increasing through July and could push temperatures higher [2]. The regulatory landscape also impacts accessibility: German GlüStV implications and US CFTC reach create a complex environment, yet the "no-KYC up to $1,500" threshold allows retail participants to access this market without immediate identity verification, provided they stay within the limit, though this does not exempt them from future compliance checks [10]. Recent forecasts for Friday 10 July show a maximum of 30°C, but the official daily high could still climb higher depending on afternoon conditions [10].
