Highest temperature in Shanghai on July 24?

Platform comparison

Market context

Shanghai’s daytime high at Pudong Airport on 24 July will depend on whether the city gets a clean, hot build-up or if cloud and showers knock the peak down before noon UTC, which is the market’s settlement cut-off. The current setup points to a classic summer-weather range: hot, humid, and interruption-prone, with nearby forecasts showing highs around 32–35°C and a meaningful rain chance in the period around 24 July.[1][2][3][4]

The 0% crowd-implied probability for the YES side is easier to read as a mechanical starting point than a view that heat is impossible. Markets on single-day weather often reprice sharply when the first credible forecast of the actual airport station lands, because one degree can move the result between adjacent bands. Shanghai’s July climate is normally warm and wet, with average highs around 32°C, heavy rainfall common, and humidity high enough to make cloud cover or convection especially relevant to the day’s maximum temperature.[2][4][5]

For traders, the main catalysts are the airport-specific Wunderground history page as the settlement source, the evolution of the final pre-settlement forecast, and any shift in rain timing, cloud cover, or wind direction that changes the daytime peak before 12:00 UTC.[3] If showers arrive early or linger, the high can undercut the broader city forecast; if the morning clears, the airport can still post a value near the upper end of the expected range.[1][3]

FAQ

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.

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.
