Pronóstico: Highest temperature in Hong Kong on July 23?

Platform comparison

Market context

Hong Kong’s 23 July maximum is usually decided by how much sunshine breaks through the summer humidity rather than by a stable seasonal average. July is the city’s hottest month, with an average high of about 32°C and an average low near 27°C, but heavy rain and storms are also common, which can cap the day’s peak if cloud cover persists.[2]

The market’s current 0% yes pricing looks aggressive against the historical range of summer outcomes. The Hong Kong Observatory has recorded 34.9°C on 23 July in one notable year, showing that the date can reach the mid-30s when conditions are clear, while broader reporting has also captured July afternoons near 37°C during exceptional heat events linked to nearby weather systems.[3][4] That makes a 34°C outcome plausible, and the gap between 33°C and 34°C in the current book suggests traders are already splitting on whether the day finishes just below or above that threshold.[1]

What matters next is the Observatory’s day-by-day evolution: afternoon cloud build-up, rainfall timing, and any typhoon-related disruptions can pull the maximum down even if the morning starts hot. The settlement source is the Hong Kong Observatory’s “Absolute Daily Max (deg. C)” in the relevant Daily Extract, so the final figure will depend on that official publication rather than intraday readings or forecasts.[1]

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.
