Highest temperature in Shanghai on July 6?

Platform comparison

Market context

Shanghai Pudong International Airport is currently experiencing hot, humid conditions with a high risk of strong thunderstorms this morning, pushing temperatures to 33°C as of 4 AM. Historical data for early July shows the coldest day in the first ten days occurred on 3 July at 24.3°C, while peak highs in late July reach 32.5°C, with 2025 recording a blistering 38°C on 3 PM. The current crowd-implied probability of 0% for the temperature exceeding 30°C appears inconsistent with these comparable cases, where daytime highs routinely hover above 30°C and often exceed 35°C during the heat of the afternoon.

Traders must monitor the afternoon weather trajectory, as scattered strong thunderstorms are forecast early afternoon, which could temporarily suppress peak temperatures or cause locally higher rain amounts. The resolution source, Wunderground, records the highest temperature for all times on 6 July, meaning a brief spike before the storms or during a sunny break could still trigger a "YES" outcome. Recent forecasts from The Weather Network confirm the risk of thunderstorms and high humidity, suggesting that while rain may cool the air, the underlying heat and solar energy levels remain elevated enough to potentially breach the 30°C threshold before the settlement window closes.

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.

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.

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.

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.
