Highest temperature in Shanghai on August 13?

Platform comparison

Market context

Shanghai's highest temperature on 13 August 2026 will be measured at Pudong International Airport Station and recorded in Weather Underground's Daily Observations table. The market resolves to the temperature range containing that peak reading in degrees Celsius. Current crowd pricing implies near-zero probability across all ranges, suggesting either extreme confidence in a specific outcome or thin liquidity at present.

Historical August temperatures in Shanghai show consistent patterns: the city experiences peak summer heat in mid-August, with daily highs typically between 32–36°C. Comparable markets on Weather Underground data have resolved within expected seasonal bounds when settlement occurs within the standard observation window. The 0% implied probability across all ranges is unusual for a weather market with defined historical precedent and suggests traders may be awaiting additional information or that the market has attracted minimal participation to date.

Regulatory accessibility differs materially by jurisdiction. Under German GlüStV rules, prediction markets on weather events face stricter classification than financial derivatives, affecting EU trader participation. US CFTC oversight extends to certain prediction market operators, though weather-based contracts typically fall outside commodity futures regulation. No-KYC access up to $1,500 USD on compliant platforms means retail traders can participate without identity verification up to that threshold, though iskalshilegit.com's specific KYC policy governs actual market entry. Traders should verify their local regulatory status before engaging; weather markets remain accessible in most jurisdictions where prediction markets operate legally.
