Highest temperature in Shanghai on August 1?

Platform comparison

Market context

Shanghai’s temperature on 1 August will be set by the highest reading recorded at Pudong Airport, not by citywide averages or a daytime forecast. In practice, that means the market is about whether the airport station posts an outright daily extreme before the settlement cut-off, with the result determined from Wunderground’s history page for Shanghai Pudong International Airport Station.

The surrounding climatology points to a hot, high-variance early-August profile. Shanghai’s August highs typically sit around 32°C to 35°C, while several weather references put typical daily highs for the month in the high 80s to mid-90s Fahrenheit, and records for the city reach about 41°C in extreme heat events.[1][2][6][8] That makes a non-zero “YES” outcome structurally plausible even if the current crowd price is 0%, because the market resolves on the single warmest observation of the day rather than an average. In that sense it resembles other event markets where one clean outcome is driven by a narrow adjudication rule: the public can overweight the forecast average, while the actual settlement depends on whether one late-afternoon spike or thunderstorm break changes the daily maximum.

Traders should watch the local hourly evolution, especially cloud cover, rainfall, and the arrival of any typhoon-linked air mass, because Shanghai’s August weather is frequently hot but can be interrupted by rain and humidity changes.[9][15][16] The most relevant dependency is the official station reading itself, since airport temperatures can differ from downtown conditions and from broader municipal forecasts. If the day begins warm and clears quickly, the high can be set early; if convection or rain develops, the ceiling can be lower than seasonal norms even on a muggy day.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

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.

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.
