Highest temperature in Wuhan on August 10?

Platform comparison

Market context

The event is whether Wuhan Tianhe International Airport reaches a specific **daily maximum temperature** on 10 August, with settlement tied to the **Daily Observations** table on Weather Underground rather than the headline Day High & Low figure. Wuhan is normally very warm in August: long-run climate pages put average highs around the low-to-mid 30s Celsius, and historical August records have reached about 41°C, so outcomes in the high-20s to low-30s remain the most plausible bands.[4][5][6][11][17]

That makes a 0% crowd price for “YES” informative only as a market signal, not as a statement of meteorology or resolution mechanics. Under the market’s own wording, the final figure depends on the airport station observation and the temperature range that contains that recorded high, which means any midday spike, rain-cooled afternoon, or local station reporting quirk can matter more than the broader city forecast. In practical terms, this is a short-dated weather contract with resolution risk concentrated in the source data rather than in general Wuhan climate averages.[1][16]

From a market-access standpoint, German GlüStV rules are relevant because they treat online gambling and closely related paid games of chance as tightly regulated, so German users may face account, payment, or geo-compliance limits depending on the venue’s structure. In the United States, CFTC jurisdiction can reach event contracts that resemble derivatives, which is why access is often restricted for US persons on some platforms. “No-KYC up to $1,500” generally means a user can trade or withdraw up to that cumulative threshold without identity verification, but once activity exceeds the cap, KYC checks typically apply, affecting who can enter and how quickly funds can move.[10]

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.

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.

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).
