Highest temperature in Seoul on July 23?

Platform comparison

Market context

The underlying event is the highest recorded temperature at Incheon Intl Airport Station on 23 July 2026, measured in Celsius and settled from Wunderground’s daily history page. The market is currently pricing **0% YES** overall, while the live outcome ladder on Polymarket shows **27°C** as the frontrunner at 49% and **28°C** at 30%, which is more consistent with a normal late-July Seoul summer profile than with an extreme heat spike.[1][2]

For context, Seoul in July typically reaches around **28°C** at the daily high, with warm nights, substantial humidity, and frequent rain risk, so the distribution tends to cluster in the high-20s rather than much lower or much higher bands.[2] A 0% headline probability is therefore best read as a market configuration issue, a stale quote, or a platform-specific mapping rather than a literal statement that the weather outcome is impossible; comparable summer temperature markets usually move with updated model runs, local forecast adjustments, and airport observations, not broad seasonal averages alone.[1][2]

From a legal-access angle, German **GlüStV** treatment can matter because prediction markets tied to weather outcomes may be viewed differently from pure financial derivatives, and access can depend on the platform’s licensing and geofencing rather than the contract itself. In the US, **CFTC** reach is relevant wherever a market is treated as a commodity derivative or event contract, so availability can hinge on whether the venue is structured to avoid US participation or regulatory touchpoints. Where a venue advertises **“no-KYC up to $1,500”**, that usually means small-value participation may be allowed with only basic account checks, but it does **not** mean the market is equally accessible from every jurisdiction or exempt from identification checks once limits, risk flags, or withdrawal thresholds are crossed.

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.

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.

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).
