Market context
Shenzhen is in its midsummer heat pattern, with July typically the hottest month and daytime highs averaging about 32°C, or 90°F, while night-time temperatures sit around 26°C.[1] WeatherSpark puts July daily highs in Shenzhen at roughly 89°F, with highs rarely falling below 84°F or above 93°F, which suggests the market is pricing an outcome that would be unusual for the city’s seasonal norm if it stays at 0% YES.[2]
For a one-day temperature market, the key comparator is not the monthly mean but the upper tail: how often Shenzhen reaches the low- to mid-30s Celsius, and whether cloud, rain, or a passing tropical system suppresses the peak. July is also a wetter month, with TravelChinaGuide noting around 17 rainy days and about 339 mm of precipitation, plus heavy showers at times, so a daytime maximum can easily be capped well below the average high when convection builds early.[1]
The main catalysts are any short-range forecasts, typhoon-track updates, and the timing of rainfall bands over Shenzhen Bao’an International Airport, because the settlement source is the station’s observed maximum for the full day rather than a forecast high. In practice, a clear, humid morning with late cloud build-up favours a higher maximum, while an early rain event or stronger monsoon influence makes lower temperature bands more likely to land.[1][2]

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.
