Market context
Hong Kong’s temperature on 31 July will be set by the Hong Kong Observatory’s final daily extract, with the market resolving on the highest official reading for the day rather than the headline citywide feel. The key reference point is how often Hong Kong reaches the upper end of its July range: the Observatory’s July rankings show the city’s record monthly maximum is 35.7°C, with 35.6°C and 35.4°C also on the board, while the Observatory reported 36.1°C on 27 July 2023 and called it one of the highest July monthly absolute maxima on record.[2][8]
That history argues for treating a zero-price outcome with caution, because late-July heat spikes are not rare in Hong Kong even if the day-to-day distribution usually sits lower. Standard July climate guides put average highs around the low 30s Celsius, and official readings published today already showed 31°C at the Observatory by 2 p.m., with several inland and urban sites at 32–33°C, which is enough to keep the top end in play if cloud cover stays limited and winds remain weak.[6][7][12]
The main catalysts are the Observatory’s afternoon updates, the eventual publication of the daily extract, and whether the city’s hottest station posts another late-day push above the early reading. Traders should also watch the regional weather statement and any short-term forecast changes from the Observatory, because Hong Kong’s highs can diverge sharply across districts and the settlement source uses the official Observatory maximum, not a neighbourhood reading.[7][14][11]

FAQ
- 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.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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.
- 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.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
