Highest temperature in Shanghai on July 5?

Platform comparison

Market context

The real-world event at stake is the peak temperature recorded on 5 July 2026 at Shanghai Pudong International Airport, with settlement relying on Wunderground’s official daily high in degrees Celsius. Historical data confirms that July in Shanghai is consistently hot and humid, with average highs between 26–31°C and frequent peaks exceeding 35°C, as seen in July 2025 when temperatures reached 38°C[2]. Given that past July highs routinely surpass 30°C, the current crowd-implied probability of 0% YES for any lower temperature range appears inconsistent with established climate patterns, suggesting either a mispricing or an unusually narrow resolution threshold[5][7].

Traders should monitor AccuWeather’s July 2026 forecast updates, which project daily highs between 80°F and 93°F (27–34°C), alongside local meteorological bulletins for sudden heatwaves or monsoon shifts that could spike temperatures beyond expectations[1][5]. Recent climate reports indicate that Shanghai’s highest average July day occurs on 29 July at 32.5°C, reinforcing the likelihood of high readings on early July dates[6]. For accessibility, the market operates under a “no-KYC up to $1,500” framework via Polymarket’s Is Kalshi Legal in California broker, allowing non-US traders to participate without identity verification, though US, UK, and EU users face geo-blocking unless using compliant intermediaries[1]. Regulatory exposure includes German GlüStV implications for onshore operators and US CFTC reach for on-chain derivatives, but the current structure remains outside direct enforcement due to its decentralised oracle settlement via UMA[1].
