Highest temperature in Chengdu on August 2?

Platform comparison

Market context

Chengdu’s airport temperature on 2 August will be judged on the single highest reading recorded at Chengdu Shuangliu International Airport Station, so the market is really about whether the day’s peak lands in a particular Celsius band rather than the exact figure itself. Seasonal context points to a warm, humid monsoon period: August average highs in Chengdu are around 29.8–31°C, with typical daily highs near 87°F/31°C and historical extremes above 39°C during heat events.[1][3][4][17]

The current 0% yes probability is best read against both the weather baseline and the legal/access framing around the venue. In Germany, GlüStV issues matter because prediction markets can be treated as gambling-adjacent products, which affects how a regulated platform approaches marketing, geoblocking, and user eligibility. In the US, CFTC reach is relevant because event contracts tied to weather can fall into a derivatives-regulatory perimeter depending on venue and structure, so accessibility is not just a weather question but a jurisdictional one. “No-KYC up to $1,500” means a user may be able to trade without identity verification until cumulative activity hits that threshold, but it does not remove country restrictions, payment screening, or local legal limits.

For traders, the main catalyst is the meteorological intraday pattern on 2 August: the highest temperature is usually set by late afternoon heating, but cloud cover, rainfall, and monsoon outflow can cap the day’s maximum well below the August norm.[1][7][17] The relevant dependency is the Wunderground airport history page used for settlement, so any late data update or station reporting anomaly would matter more than citywide forecasts; by contrast, broad Chengdu outlooks and travel guides mainly help frame expectation, not resolve the market.[1][7][14]

FAQ

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

What happens during a tax audit?

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

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).

What if regulation changes?

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