Highest temperature in Shenzhen on August 4?

Platform comparison

Market context

Shenzhen’s official airport reading for 4 August is usually decided by how much heat can break through the city’s humid, rain-prone summer pattern. August climatology points to daytime highs around 31–32°C, but the same sources also describe frequent rain, heavy humidity and a typhoon-prone season, all of which can cap the day’s peak if cloud cover and showers persist.[3][8][18][19][20]

The current 0% YES crowd price looks out of step with the historical baseline if the market’s top band includes the low 30s, because multiple August guides place Shenzhen’s typical high close to 32°C and Wunderground-linked resolution will use the airport station’s *actual* daily maximum rather than a citywide forecast.[3][8][18][20] Comparable weather markets are often driven more by the late-morning and early-afternoon spike than by the day’s average, so traders usually watch whether the forecast trends towards sun breaks or keeps the airport under overcast and rain.

For this contract, the key catalysts are the evolution of the local forecast, any tropical disturbance near Guangdong, and the hourly airport observations that determine the realised high before the 12:00Z settlement cut-off. Hong Kong’s 24-hour Guangdong bulletin currently has Shenzhen at 25–29°C with overcast conditions, which points to a subdued ceiling unless the afternoon warms faster than expected.[5] The market is therefore more sensitive to short-notice forecast shifts than to broad seasonal averages, especially on a day when convection and coastal cloud can change the day’s maximum quickly.[5][16]

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.

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.

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.

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.
