Highest temperature in Beijing on July 9?

Platform comparison

Market context

The real-world event hinges on the peak temperature recorded at Beijing Capital International Airport on 9 July 2026, a date historically prone to extreme heat. While the current crowd-implied probability for a specific outcome sits at 0%, this contradicts broader market data where 34°C is the frontrunner at 53% and 35°C follows at 32%[1]. Historical patterns confirm July is Beijing’s hottest month, with average highs reaching 31°C and frequent spikes well above 30°C[5][6]. Comparable cases from recent years show temperatures regularly climbing to 30°C or higher, with some days exceeding 35°C, suggesting the 0% probability may reflect a mispricing rather than an actual impossibility of the event occurring[7].

Traders should monitor the daily weather forecast for Beijing, particularly the ultraviolet intensity and rain patterns, as July is the rainy season with changeable conditions[3]. The settlement relies on Wunderground data for the highest temperature recorded at all times on that day, making real-time updates from the National Weather Service critical for accuracy[4]. Recent forecasts for July 2026 indicate daily highs ranging from 84°F to 91°F (approximately 29°C to 33°C), with overnight lows between 68°F and 76°F[8]. Regulatory accessibility remains a key factor: German GlüStV implications and US CFTC reach define the legal framework, while the “no-KYC up to $1,500” threshold allows immediate participation for smaller trades without identity verification, enhancing liquidity for this specific market[1].
