Highest temperature in Hong Kong on July 1?

Platform comparison

Market context

On 1 July 2026, Hong Kong will record its highest daily temperature, a figure that determines the outcome of a prediction market where the crowd currently assigns zero per cent probability to the “YES” outcome. This event hinges on the Hong Kong Observatory’s official “Absolute Daily Max” reading, finalized in its Daily Extract, and reflects the city’s intense summer heat, with July historically being the hottest month.

Historical data shows Hong Kong’s July highs routinely exceed 34°C, as seen in July 2024 when temperatures peaked at 34.8°C on 7 July[4], and in July 2018 with a mean maximum of 31.8°C[1]. The 2021 annual mean was the warmest since records began in 1884, underscoring a long-term warming trend[7]. Given this precedent, a zero per cent crowd-implied probability appears inconsistent with the region’s climatic reality.

Traders should monitor the Observatory’s Daily Extract release schedule, which typically follows data finalisation within days of the event, and watch for any official weather bulletins confirming record-breaking conditions. Recent reports from China Daily highlight that July has been the hottest month on record in Hong Kong, with temperatures nearing historic highs[9]. The market’s resolution depends entirely on this published data, making timing and source reliability critical catalysts.

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.

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.
