Pronóstico: Highest temperature in Chengdu on August 4?

Platform comparison

Market context

Chengdu’s **4 August** maximum is usually set by a hot, humid afternoon rather than a dry heat, and the market settles on the highest reading at Chengdu Shuangliu International Airport Station that day. Climatology points to a fairly tight late-summer band: August averages are around **30–32°C** for daytime highs, while comparable August guides put Chengdu’s typical high near **30°C** and the early-August average around **32.3°C**.[2][5][7][18]

That makes the crowd’s **0% YES** on any extreme outcome easy to understand if the listed threshold is above the low-30s, because most reference forecasts cluster in the **32–35°C** zone rather than at the top of the scale.[1][3][9][14][17] The main reason temperatures fail to overshoot in Chengdu is cloud, humidity and intermittent rain: August is repeatedly described as hot, muggy and rainy, with showers often limiting full insolation even when the day starts warm.[2][5][11][13]

For traders, the key catalyst is whether late-morning cloud breaks long enough for a strong afternoon spike before moisture or thunderstorms cap the peak. Forecasts currently point to **patchy rain possible** and highs around **32–34°C** on 4 August, which keeps the distribution centred just above 30°C and makes a clean move into the mid-30s dependent on sunshine, wind and storm timing rather than any structural cold bias.[1][3][6][9][10][17] Because the market resolves off the airport station’s recorded maximum, the final print will depend on the day’s actual hourly observations, not citywide averages.[14][15]

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.

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.
