Highest temperature in Guangzhou on July 6?

Platform comparison

Market context

Guangzhou Baiyun International Airport will record its peak daily temperature on 6 July 2026, a real-world event that determines the settlement of this prediction market. The current crowd-implied probability of 0% for a specific temperature range suggests the market views that outcome as virtually impossible, yet historical data contradicts such certainty. July is the hottest month in Guangzhou, with an average temperature of 28.3°C and daily highs frequently reaching 30°C or higher, defining “hot days” by Greenpeace thresholds[1][5]. Extreme hot days have more than doubled since the 1960s across East Asia, and China recently experienced its hottest July on record since 1961, with average temperatures hitting 23.2°C[1][3]. This precedent of rising heat waves and record-breaking summer days frames the 0% probability as potentially misreading the cultural narrative of escalating climate momentum.

Traders should monitor official heatwave announcements from the China Meteorological Administration and scheduled weather bulletins for the Guangdong region, as these directly influence peak temperature outcomes. Recent reports confirm Guangzhou has seen its longest summer since 1961, with Wednesday’s average temperature reaching 23.3°C, indicating sustained thermal pressure[6]. Dependencies include the timing of the settlement window ending at 12:00 UTC, which may exclude afternoon peaks if the station records higher temperatures later in the day. The resolution source is Wunderground data for the Baiyun station, so any discrepancies in its reporting schedule could alter the final figure. With Polymarket showing a 30% probability for 32°C on a nearby date, the market may be underestimating the likelihood of extreme heat in early July[4].

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.

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.

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.
