توقع: Highest temperature in Shanghai on August 18?

Platform comparison

Market context

Shanghai's highest temperature on 18 August 2026 will be measured at Pudong International Airport Station and recorded in Weather Underground's Daily Observations table. The settlement window closes at midday UTC on that date, meaning the full day's temperature range will be captured before resolution. August in Shanghai typically sees daily highs between 32–35°C, with humidity often exceeding 70%, though extreme heat events pushing above 37°C do occur during summer heat waves.

Historical August data from Shanghai shows that temperatures exceeding 38°C are rare but not unprecedented; the city recorded 40.9°C in July 2022 during an exceptional heat event. The 0% crowd probability suggests traders are pricing in either a specific temperature threshold being unlikely or uncertainty about which range band the market offers. Without visibility on the exact temperature brackets available, the current odds reflect scepticism that an unusually high reading will occur on that particular date, though Shanghai's August climate remains volatile enough that significant heat is plausible.

Traders should monitor China's meteorological forecasts from late July onwards, particularly any alerts issued by the China Meteorological Administration regarding heat waves or extreme weather patterns affecting the Yangtze River Delta region. Urban heat island effects in Shanghai's commercial districts can push local readings 2–3°C above airport measurements, though Pudong station itself sits in a relatively open area. The resolution source's reliance on Weather Underground's Daily Observations table rather than summary figures means precision in data collection matters; any discrepancies between sources will favour the granular hourly records.

Methodology

Football-specific comparison page for توقع: Highest temperature in Shanghai on August 18?. 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.

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.

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.
