Highest temperature in Shanghai on July 10?

Platform comparison

Market context

The real-world event this market tracks is the highest temperature recorded at Shanghai Pudong International Airport on 10 July 2026, measured in degrees Celsius and sourced from Wunderground. Historical July data for the airport shows daily highs typically ranging between 29.8°C and 30.7°C in the first half of the month, with extremes often exceeding 35°C during hotter spells [5][9]. While the current crowd-implied probability for a “YES” outcome sits at 0%, comparable Polymarket events have assigned 36% probability to 32°C and 27% to 31°C, suggesting short-term model runs remain the decisive variable traders monitor ahead of final resolution [3].

Traders should watch for updated weather forecasts, especially from AccuWeather and Yr, which project daily highs between 86°F and 97°F (roughly 30°C–35.5°C) for Shanghai Pudong in July 2026 [1][10]. Key catalysts include announcements from Chinese meteorological authorities, shifts in regional humidity or cloud cover, and any delays in Wunderground’s data upload schedule. Regulatory accessibility also matters: under Germany’s GlüStV, prediction markets may face stricter licensing, while the US CFTC maintains broad reach over digital derivatives. The “no-KYC up to $1,500” threshold enhances accessibility for this market, allowing retail participants to trade without identity verification, though compliance obligations still apply depending on jurisdiction.
