Highest temperature in Shanghai on July 18?

Platform comparison

Market context

Shanghai's summer temperatures in mid-July routinely exceed 35°C, with the city's humid subtropical climate producing some of the year's most extreme heat. The Pudong International Airport station, located east of the urban centre, typically records slightly cooler readings than downtown areas due to proximity to the Huangpu River and coastal influences, though daily highs in the 33–37°C range remain standard for this period. Historical data from the past decade shows July 18 has seen peaks ranging from 32°C to 37°C, with no single day establishing a consistent pattern that would favour any particular temperature band.

The 0% crowd probability suggests traders are either abstaining entirely or treating the market as insufficiently liquid to engage with meaningfully. This contrasts with comparable weather markets on the platform, which typically attract modest participation even for routine seasonal forecasts. The settlement mechanism—drawing directly from Wunderground's historical records for a specific monitoring station—removes interpretive ambiguity, yet the absence of trading activity indicates either market saturation at other venues or genuine indifference to Shanghai's July temperatures as a prediction category.

Traders monitoring this market should note that China's meteorological data occasionally experiences reporting delays or station maintenance windows, though Wunderground's historical archive generally captures readings within 24 hours of occurrence. No scheduled weather events or anomalies are forecast for mid-July 2026 that would materially shift Shanghai's baseline summer conditions from typical patterns.

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.

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.
