Highest temperature in Hong Kong on July 11?

Platform comparison

Market context

Hong Kong is entering its hottest month of the year, with July historically delivering the peak daily maximum temperatures recorded by the Hong Kong Observatory. The current 0% crowd-implied probability for a specific outcome suggests traders are either betting on a resolution failure due to missing data or misinterpreting the market’s temperature-range mechanics, as July 11 falls squarely within the period of extreme heat driven by a dominant subtropical ridge.

Historical data frames this event sharply: July 2024 was exceptionally hot, with the Observatory recording a peak of 34.8°C on 7 July, while monthly mean maximums have consistently ranked among the highest on record [1][3]. Comparable years show daily highs frequently exceeding 33°C during mid-July, making any temperature range below 32°C statistically improbable for this date. The 0% probability likely reflects a confusion over the settlement window ending in 2026 rather than a genuine belief that no high temperature will be recorded.

Traders must monitor the publication of the “Daily Extract” from the Hong Kong Observatory, which finalises the “Absolute Daily Max (deg. C)” for 11 July 2026 [6]. The market cannot resolve until this official data is released, creating a dependency on the Observatory’s schedule rather than weather forecasts. Recent climate summaries confirm July remains the hottest month, with average highs around 32°C (89°F), reinforcing that a valid temperature reading will almost certainly exist once the data is finalized [2][5].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
