Highest temperature in Shanghai on August 5?

Platform comparison

Market context

Shanghai’s reading will be the **highest temperature at Pudong airport** during the settlement day, not the citywide forecast headline, so the market is really about a single-station daily maximum. With late-summer Shanghai usually running hot and humid, nearby August climatology points to highs around the low-30s Celsius, while day-specific forecasts for 5 August cluster around the mid-30s Celsius and allow for some rain or thundery disruption rather than a cool-out outcome.[1][2][8][12]

For framing, the current **0% YES** is hard to read as a view on the weather itself and more likely reflects thin liquidity or an unpriced market, because a daily Shanghai high above the lower Celsius bands is well within historical and forecast norms. Comparable summer cases in Shanghai often resolve in the mid-30s Celsius range, and airport observations can differ materially from city-centre forecasts when convection, sea breeze, or showers briefly cap the peak; the Wunderground station data, not a general forecast, will decide this market.[2][3][7][16]

From a legal-access standpoint, this sits in the familiar prediction-market overlap of weather data and regulatory exposure: German **GlüStV** treatment turns on whether the venue is viewed as a gambling product, while the US **CFTC** can reach event contracts that fall within its jurisdiction. Where a platform advertises **“no-KYC up to $1,500”**, that usually means smaller participation is possible before identity verification is requested, but it does not alter the underlying geoblocking, sanctions screening, or country-specific access rules for a weather market like this.

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.

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.

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.

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).
