Highest temperature in Shenzhen on July 22?

Platform comparison

Market context

Shenzhen Bao'an International Airport is already running hot, with AccuWeather showing 88°F, sunny conditions, and humidity high enough to push the RealFeel to 100°F by late morning UTC.[1] For this market, the key question is whether the airport station’s daily high stays in the low-30s Celsius or edges higher before the settlement window closes.

The current 0% price on the colder bands is only useful as a reference point: it reflects how far the forecast has shifted away from a cool outcome rather than any guarantee about the final reading.[2] On a summer day in Shenzhen, the more relevant comparison is whether cloud cover, rain, or a sea-breeze-type moderation arrives in time to cap the maximum temperature before early afternoon local time, when highs are often set.

What traders should watch is any late change in the local forecast between now and the settlement cut-off, especially updates to humidity, cloud cover, and wind that can move the airport’s peak reading by a degree or two. The resolution source is Wunderground’s daily history for Shenzhen Bao'an International Airport, so the decisive data point is the highest observed temperature there on the calendar day, not the citywide average or a forecast high.[2]

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.

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.
