Highest temperature in Chengdu on July 23?

Platform comparison

Market context

Chengdu’s official airport station will settle the market on the day’s peak temperature, so the relevant question is whether the city gets a modest July high or a hotter-than-average spike. Current market pricing is concentrated around **38°C** and **39°C**, with 38°C leading at 44% and 39°C at 22%, which implies traders are treating the upper-30s as the most likely band rather than an extreme break-out.[1]

That distribution fits Chengdu’s July pattern, where highs commonly sit in the low 30s but can edge higher in warmer spells. Historical and forecast-based weather pages for Chengdu point to typical July highs around 31–32°C, with day-to-day variation around that level, so a 0% view on the market’s lower outcomes is hard to reconcile with the city’s summer climatology.[2][3] In practice, any sustained clear-sky heat, a hot air mass moving in, or a weak monsoon break would be enough to push the airport reading towards the market’s leading bins.

For traders, the key catalysts are the airport-station forecast updates, any change in cloud cover or rainfall timing, and whether the overnight minimum stays elevated enough to support a hot afternoon. The settlement source is the Wunderground history page for Chengdu Shuangliu International Airport Station, so late adjustments to the observed daily high matter more than broad city forecasts.[1] The most useful watchpoints are the midday forecast revisions and any mention of thunderstorms, which can cap the day’s maximum even if earlier guidance looks warm.[3]

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.

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.
