Highest temperature in Chengdu on July 13?

Platform comparison

Market context

The market tracks the peak Celsius temperature at Chengdu Shuangliu International Airport on 13 July 2026, a date historically prone to extreme heat in China’s southwest. July is Chengdu’s hottest month, with average highs of 28–30°C and frequent spikes to 38°C, while record data shows a peak of 38.6°C in August 2022 and a national July 2023 record for the hottest month since 1961[2][3][5][9]. The current 0% YES probability for any outcome implies a market error or misalignment, as Polymarket data shows 38°C as the frontrunner at 89% in one snapshot and 34% in another, with 37°C next at 28%, contradicting the zero-probability stance[1].

Traders should monitor Wunderground’s daily history for ZUUU as the settlement source, watching for real-time heatwave announcements from China’s National Meteorological Centre and regional Yangtze River basin forecasts that have driven past record-breaking events[1][8]. The German GlüStV framework classifies such weather derivatives as gambling under state licensing rules, while the US CFTC asserts reach over prediction markets offering binary outcomes on non-financial events, creating dual-regulatory exposure. The “no-KYC up to $1,500” threshold means this market remains accessible to users without identity verification below that limit, but transactions above it trigger compliance checks, limiting anonymity for larger positions while keeping entry open for retail traders under the threshold.
