Highest temperature in Shanghai on August 16?

Platform comparison

Market context

Shanghai's highest temperature on 16 August 2026 will be recorded at Pudong International Airport Station and measured in degrees Celsius. The market resolves using Weather Underground's Daily Observations table as the authoritative source, superseding any conflicting figures in the Day High & Low summary section. Settlement occurs at 12:00 UTC on that date.

The 0% crowd probability reflects the market's nascent state rather than meteorological certainty. August temperatures in Shanghai historically peak between 32–35°C, with extremes occasionally reaching 37–38°C during heat waves. The 2013 heat event saw Shanghai record 38.2°C on 6 August; more recently, July 2022 brought sustained temperatures above 35°C across the region. Comparable prediction markets on Shanghai summer temperatures have typically seen meaningful trading activity only in the final week before settlement, when weather models converge and forecasters issue official heat warnings.

Traders should monitor China Meteorological Administration forecasts and Shanghai municipal heat-alert announcements, typically issued 3–5 days ahead of extreme conditions. The East Asian summer monsoon's intensity in mid-August will determine whether tropical air masses dominate or cooler systems prevail. Recent reporting from Xinhua and local Shanghai media outlets has highlighted climate variability in 2024–2025, though long-range August 2026 forecasts remain unreliable until late July. From a regulatory standpoint, this market falls within German GlüStV's scope for EU traders; US CFTC jurisdiction applies to US persons regardless of location. The no-KYC threshold of $1,500 USD permits casual participation in this specific market without identity verification for qualifying traders, though platform terms and user jurisdiction ultimately determine 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 Germany Legal has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Germany Legal 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 Germany Legal 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).

What if regulation changes?

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