Highest temperature in Chengdu on August 4?

Platform comparison

Market context

The real-world event is the highest temperature recorded at Chengdu Shuangliu International Airport on 4 August, measured in Celsius and settled from Wunderground history data. Current August climatology for Chengdu points to a hot, humid monsoon-season profile, with typical daytime highs clustered around 30–32°C and some forecasts for 4 August sitting near 31–34°C, which makes the market’s 0% YES position on an extreme outcome hard to reconcile with the normal range of outcomes.[1][2][3][7][18]

For context, August is usually Chengdu’s hottest period, but afternoon convection can keep peaks a little below the surrounding regional heat. Comparable weather pages for the date show scattered rain risk and highs around 32°C, while other forecast outlets publish values in the low-to-mid 30s, so traders should treat the live model spread as the key reference rather than any single daily number.[1][2][3][5][9][12][17] Under German GlüStV framing, access from Germany can be restricted where an operator lacks the relevant authorisation, while US-facing activity may still fall within the CFTC’s reach if the venue is considered to offer event contracts to US persons; “no-KYC up to $1,500” generally means a user can transact up to that threshold with lighter identity checks, but it does not remove geo-blocking, tax reporting, or rule-based limits on participation in this specific market.

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.

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.

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).
