Highest temperature in Shanghai on August 19?

Platform comparison

Market context

Shanghai's highest temperature on 19 August 2026 will be measured at Pudong International Airport Station and recorded in Weather Underground's Daily Observations table, with settlement determined by that primary source rather than any summary figures. The market resolves to a temperature range in degrees Celsius, and the 0% crowd probability suggests traders currently assign negligible likelihood to the upper bound of the range specified.

Historical August temperatures in Shanghai show consistent patterns: the city experiences peak summer heat in mid-August, with daily highs typically between 32–35°C, though extremes occasionally exceed 37°C during heat waves. Comparable markets on Shanghai summer temperatures have resolved across a wide distribution, reflecting the region's variable monsoon influence and occasional tropical systems that alter expected conditions. The current zero probability reflects either an extremely high threshold in the range definition or early-stage market formation with limited participation.

Traders monitoring this market should track China Meteorological Administration forecasts released in early August 2026, which provide 10-day outlooks for the Yangtze River Delta region. Typhoon activity in the Western Pacific during mid-August can substantially shift Shanghai's weather patterns and temperature profiles. The settlement window closes at 12:00 UTC on 19 August, allowing only same-day resolution based on recorded station data.

From a regulatory standpoint, this market falls under German GlüStV provisions for prediction markets operating within EU jurisdiction, whilst remaining subject to CFTC oversight if marketed to US persons. No-KYC access up to $1,500 USD notional exposure applies to this specific market, permitting retail participation without identity verification below that threshold, though operators must maintain compliance documentation for regulatory review.

FAQ

Do I need to KYC for Polymarket Germany Legal?

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.

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 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).
