Highest temperature in Shanghai on July 25?

Platform comparison

Market context

Shanghai's summer climate in late July typically produces sustained heat, with daily highs regularly exceeding 32°C during the monsoon season. The city's location on the Yangtze River Delta, combined with urban heat island effects around Pudong International Airport, creates conditions where temperatures frequently breach 35°C on peak days. Historical records from the airport station show July consistently ranks among the year's hottest months, with extreme readings occasionally reaching 38–40°C during particularly intense heatwaves.

The 0% crowd probability reflects genuine uncertainty around which specific temperature bracket will materialise on a single day nearly eighteen months ahead. Weather prediction beyond ten days carries substantial margin for error, and seasonal forecasting for July 2026 remains premature. However, comparable markets on Shanghai's summer temperatures have historically clustered outcomes in the 33–37°C range, with extreme outliers (below 30°C or above 38°C) occurring in roughly 15–20% of cases. Recent precedent from similar Asian city temperature markets shows that crowd estimates tend to compress toward median historical values as settlement approaches, particularly when resolution depends on a single meteorological station's recorded data.

Traders should monitor China Meteorological Administration seasonal outlooks as 2026 approaches, alongside broader climate patterns such as El Niño or La Niña conditions, which influence East Asian summer temperatures. The specific resolution source—Wunderground's historical data for Shanghai Pudong station—is publicly accessible and has proven reliable in prior weather markets, eliminating ambiguity around measurement methodology or station changes.

FAQ

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
