Highest temperature in Seoul on July 18?

Platform comparison

Market context

On 18 July 2026, the highest temperature recorded at Incheon International Airport Station will determine the settlement outcome. Seoul's summer climate typically peaks in late July, with daily highs averaging 28–30°C, though heat waves can push readings above 33°C. The resolution will draw from Wunderground's historical weather database, which archives hourly observations from the airport's official meteorological station.

The 0% crowd probability reflects the market's nascent state rather than any meteorological certainty. Historical precedent shows Seoul's July temperatures cluster predictably: since 2010, the 18th has recorded highs between 25°C and 34°C in most years, with only three instances exceeding 32°C. The Korea Meteorological Administration publishes daily forecasts and seasonal outlooks; traders should monitor their mid-July 2026 advisory for any anomalous pressure systems or tropical cyclone activity that could suppress or elevate temperatures. Recent summers (2023–2024) saw intensified heat waves linked to Pacific high-pressure systems, a pattern worth tracking as the settlement date approaches.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under Germany's GlüStV framework, prediction markets require licensing; however, many platforms operate under exemptions for small-stake contracts. US CFTC oversight applies to derivatives contracts with US persons, though weather futures on established exchanges enjoy clearer safe harbours. Most platforms permit unverified trading up to approximately $1,500 USD equivalent per user, meaning this weather market may be accessible without full KYC documentation in several territories—a material consideration for retail participation.

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.

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.
