Highest temperature in Guangzhou on August 14?

Platform comparison

Market context

On 14 August 2026, the highest temperature recorded at Guangzhou Baiyun International Airport Station will determine this market's settlement. The resolution relies on Weather Underground's Daily Observations table rather than the summary Day High & Low section, a distinction that matters when discrepancies arise between automated station feeds and aggregated displays. Guangzhou's August climate typically peaks between 32–35°C, though heat waves can push readings higher; the specific range brackets will define which outcome resolves TRUE.

Historical August temperatures at Baiyun station show consistent volatility. Between 2015 and 2024, daily highs in mid-August ranged from 29°C to 37°C, with 2022 recording 36°C on 14 August itself. The current 0% implied probability suggests traders expect a temperature below the lowest available range bracket—an outcome possible during tropical storm activity or unusual atmospheric conditions, though rare in Guangzhou's summer pattern. Comparable weather markets on similar Asian airport stations typically see probability mass concentrated in the 33–36°C bands during this season.

Traders should monitor tropical cyclone forecasts from the China Meteorological Administration and regional typhoon tracking through mid-August 2026, as systems approaching southern China can suppress daytime maxima significantly. The settlement window closes at 12:00 UTC on 14 August, allowing only morning-recorded temperatures to influence resolution; afternoon readings after that timestamp will not be captured. Regulatory access varies: German traders face GlüStV restrictions on prediction markets unless operating through licensed venues; US CFTC oversight applies to derivatives-like instruments but typically exempts binary weather contracts under $1,500 notional value, meaning no-KYC entry thresholds may apply depending on the platform's jurisdictional registration.

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 Germany Legal 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 Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
