Pronóstico: Highest temperature in Shanghai on August 2?

Platform comparison

Market context

Shanghai’s hottest hour on 2 August will be judged against a city that is normally near its summer peak: August average highs in Shanghai sit around 32–35°C, with daily highs often in the high 20s to mid-30s Celsius and only occasionally dropping much below that range.[1][2][3] For comparison, one Shanghai weather guide shows 2 August averaging about 34.9°C, while broader August records cited by other weather sites run as high as 40–41°C, so the distribution still leaves room for a notably hot afternoon if conditions align.[5][6][7]

For traders, the key variable is whether Shanghai Pudong International Airport gets a clear, humid, low-wind setup or a rain-influenced cap on temperatures, because the market settles on the highest reading recorded at that station before the noon UTC cut-off in the source window.[8][15] Seasonal guidance for August points to persistent heat, high humidity and meaningful rainfall risk, with forecasts and history both showing day-time highs commonly around 31–32°C and occasional spikes into the mid-30s Celsius.[8][11][17] With the current crowd-implied probability at 0% YES, the market is pricing in either a lower-than-average maximum or a failure to catch a hot midday reading, rather than a full summer heat event.[3][9][11]

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.
