Market context
Shenzhen Bao’an is in its hottest stretch of the year, and the market will settle on the day’s **highest recorded temperature** at the airport station rather than the mean or evening reading. Historical August normals cluster around **31-32°C** for the daily high, with typical highs near **89-90°F** and lows around **79-81°F**, which is why the crowd’s 0% YES implies an outcome well outside the usual summer envelope.[2][10][13]
Comparable August guides point to a fairly tight but still heat-prone distribution: average highs sit around **90°F**, while some sources show day-specific August highs in the **mid-90s°F** on the warmest dates, and one weather-history source cites a recorded August maximum of **103°F** in Shenzhen.[1][4][8] That gives traders a frame: anything in the low- to mid-30s Celsius is normal, but a genuinely extreme spike is the sort of tail event that can move a temperature-range market quickly.[1][4][8]
The main catalysts are local weather drivers rather than team-news style updates: cloud cover, rainfall bands, and especially typhoon-related systems in the South China Sea can cap the daytime high or, if they clear late, allow a hotter peak before settlement.[18] Because the window closes at **12:00 UTC**, the first half of the local afternoon is what matters most; the airport reading on Wunderground can still move materially if showers arrive early or if heat builds under clearer skies.[18][16]
Methodology
Football-specific comparison page for توقع: Highest temperature in Shenzhen on August 1?. 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
- 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.
- 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.
