Highest temperature in Chongqing on August 4?

Platform comparison

Market context

The event is the highest temperature measured at Chongqing Jiangbei International Airport during the day, and the published resolution source is Wunderground’s daily history page for that station. In late summer, Chongqing is usually very hot and humid, with August averages around the low- to mid-30s Celsius and historical highs often in the mid-30s, while occasional spikes into the high-30s are well documented in city climate summaries.[1][5][8][11]

That backdrop matters because a 0% YES crowd price is only coherent if traders think the market is mis-specified, stale, or effectively inaccessible rather than if they expect a cool day; August is typically the hottest month in Chongqing, and 4 August historical guidance from Travel China Guide shows a normal daily high around 34.6°C for that date.[1][5][8] Comparable city-level heat markets have tended to be driven by whether local convection, monsoon rain, or heatwave conditions push the airport station above the expected range, rather than by broad city averages.[1][11]

For catalysts, the key inputs are the day’s forecast trend, any heatwave or rain warnings, and whether afternoon showers cap the airport maximum before the 12:00 UTC settlement window closes; recent reporting has already shown Chongqing residents seeking shelter from heatwave conditions, underscoring how quickly these markets can move when regional heat persists.[19] On access, German GlüStV rules can affect whether a user-facing platform is treated as offering gambling-like products, while US CFTC reach matters if trading is deemed to involve event contracts available to US persons; “no-KYC up to $1,500” means some users may be able to transact below that threshold without identity verification, but it does not remove those regulatory constraints for this market’s accessibility.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
