Highest temperature in Shanghai on August 10?

Platform comparison

Market context

Shanghai’s highest temperature on 10 August will be settled off the Weather Underground **Daily Observations** table at Shanghai Pudong International Airport, so the key question is the day’s peak reading rather than the broader “Day High & Low” summary. Early signals point to a hot, humid summer setup: Shanghai’s August averages are around 32–33°C for daytime highs, with some historical 10 August readings comfortably above 35°C.[2][15]

That means the current **0% YES** looks more like a pricing artefact than a statement that 35°C-plus is impossible. For context, recent August data and historical histories show Shanghai regularly reaches the low-to-mid 30s Celsius, and some years have pushed higher, which is the same sort of pattern seen in weather markets where public price can lag a routine but weather-dependent outcome until the intraday observation path becomes clearer.[3][11][15] In market terms, this is closer to a “jury versus public split” dynamic than a pure consensus call: the public may anchor to the visible headline forecast, while the settlement source depends on the station record actually printed in the table.

Traders should watch the station-by-station update cadence through the day, especially whether forecast highs are revised up or down in the run-up to local afternoon heating, because that is when the daily maximum is most likely to form.[1][13] The practical catalyst is not a scheduled announcement but the evolving observation data itself: if cloud cover, rainfall, or stronger winds hold temperatures down, the market can stay in a lower band; if sunshine breaks through, Shanghai’s normal August climatology leaves room for a mid-30s outcome.[1][4][18]

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.

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.
