Highest temperature in Beijing on July 7?

Platform comparison

Market context

Beijing’s July 7, 2026, high temperature at the Capital International Airport is the real-world event determining this market’s outcome, with the crowd currently assigning zero probability to any temperature exceeding 32°C. Historical data shows July is Beijing’s hottest month, with average maximums near 33°C and peaks reaching 42°C in 2010[8]. Daily highs in July typically hover around 31°C (88°F), rarely dropping below 26°C or exceeding 36°C[1]. The all-time record of 41.9°C occurred on July 24, 1999, confirming that extreme heat is possible in this period[5]. Given these patterns, the current 0% probability appears inconsistent with typical July conditions, suggesting the market may be mispricing the likelihood of a 32°C+ day.

Traders should monitor emerging weather forecasts and any official heat advisories from Chinese meteorological authorities, as these often precede significant temperature spikes. Recent reports note China experienced its hottest July on record in 2024, with national averages hitting 23.21°C, surpassing the 2017 benchmark[7]. This trend of intensifying summer heat could elevate the risk of a 32°C+ day on July 7, 2026. While no specific political announcements or campaign-finance disclosures directly influence temperature, broader climate policy debates may indirectly shape public awareness and preparedness. The market is leaning on the catalyst of sustained regional heat, supported by data from Reuters and Anadolu Ajansı confirming record-breaking summer temperatures in recent years[3][7].

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
