Highest temperature in Hong Kong on July 20?

Platform comparison

Market context

Hong Kong’s highest temperature on 20 July 2026 remains unrecorded as the settlement window closes, with the Hong Kong Observatory yet to publish the finalized “Absolute Daily Max” in its Daily Extract. The current 0% YES probability reflects the absence of any confirmed data point, not a prediction of a specific temperature range, since the market cannot resolve until the official figure is released.

Historically, Hong Kong’s July highs cluster between 31°C and 35°C, with the 2023 peak reaching 35.2°C on 22 July, while the 2024 record for the month was 34.8°C on 18 July; no July day since 2010 has exceeded 36°C. The 0% probability aligns with this pattern, as traders treat the market as unresolved rather than betting against a specific range before data publication.

Traders should monitor the Hong Kong Observatory’s Daily Extract release schedule, typically published within 24–48 hours after the date, and watch for any typhoon warnings or heatwave advisories that could delay data finalisation. A recent heatwave alert issued by the Observatory on 18 July 2026, citing sustained high humidity and urban heat retention, suggests elevated temperatures may be recorded, but the official figure remains pending [1]. Until the Daily Extract is published, the market stays in limbo, with no resolution possible.

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.

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.

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.
