Market context
Guangzhou Baiyun International Airport is the event location, and the market resolves on the hottest reading logged there on 1 August. With settlement tied to a single-day maximum rather than a daily mean, the key issue is whether the airport gets a brief heat spike before cloud, rain or thunderstorm activity trims the ceiling.
August in Guangzhou is normally hot enough that the market should not be read through a cold-season lens. Long-run climate data put typical August highs around 33°C to 33.2°C, with average lows near 25°C to 27°C, while broader city guides describe the month as hot, humid and wet, with frequent rain and typhoon influence[1][16][17][18][20]. That makes 0% for a high-temperature outcome hard to square with seasonal norms: the baseline expectation is for a reading well above anything cool enough to support an extreme low maximum. Comparable August records also show that daily highs can run into the mid-30s Celsius on hot spells, with some days reaching 35°C to 36°C in Guangzhou city-centre references[4][20].
The main trader watchpoints are the short-term forecast, any rain band crossing the Pearl River Delta, and whether afternoon convection develops early enough to cap the airport maximum. AccuWeather’s current August 2026 outlook for Guangzhou shows daily highs mostly between 89°F and 93°F, roughly 32°C to 34°C, which is consistent with a high ceiling even if showers arrive later[10]. For a market ending at 12:00 UTC, the relevant window is the morning-to-early-afternoon period in Guangzhou, so any overnight cloud cover, early precipitation, or a suppressed marine air mass matters more than the full-day forecast.

Resolution & payout
Sports markets typically settle on official final-whistle plus league confirmation. Polymarket uses UMA Optimistic Oracle with a source URL per contract — usually official league data feeds or ESPN/Soccerway. Two-hour dispute window, then smart-contract payout in USDC.
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.
- 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.
- 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.
