Market context
Shenzhen Bao’an International Airport is in a humid subtropical climate where August is typically hot but also one of the wettest months, and the daily high commonly sits around the low 30s Celsius rather than pushing into extreme heat for long periods.[1][13][17] That makes the market’s current 0% YES pricing look anchored to a very high threshold rather than a true zero-risk weather day: the climatology supports warmth, but it also points to frequent cloud cover, showers, and thunderstorms that can cap the day’s maximum temperature.[1][20]
Comparable August readings for Shenzhen cluster around 31°C to 33°C, with several forecast sets showing highs near 31°C on 5 August and broader monthly highs around 32°C to 33°C.[1][3][13] Historical guides also place August’s average high close to 32°C, while rainfall is elevated, which matters because a wet morning or persistent cloud can prevent the airport station from reaching the top end of the month’s range even when the air mass is warm.[1][17] In other words, the market is most sensitive to whether the day clears into a brief hotter spell rather than simply being another standard midsummer day.
The main catalysts are the official day-of forecast updates, especially any shift in shower timing, thunderstorm coverage, or cloud breaks before the midday UTC settlement window closes at 12:00 UTC.[1][9] The resolution source is the Shenzhen Bao’an International Airport station on Wunderground, so traders should track that station’s hourly evolution rather than citywide commentary, because airport conditions can differ from downtown Shenzhen and the highest temperature is what counts for settlement.[9][10]
Methodology
Football-specific comparison page for Pronóstico: Highest temperature in Shenzhen on August 5?. Polymarket's live quote (Polygon order book) plus platform attributes for the three reference venues. Sports markets reward liquidity — Polymarket and Betfair are materially deeper than Kalshi (US-focused) or Manifold (play-money).
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.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- 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.
