Highest temperature in Seoul on July 14?

Platform comparison

Market context

On 14 July 2026, the highest temperature recorded at Incheon International Airport Station will fall into one of several defined ranges, measured in degrees Celsius. The settlement will draw from Wunderground's historical weather database for that specific location and date, with resolution occurring at 12:00 UTC on the settlement window close. Seoul's mid-July climate typically produces daily highs between 28 and 33 degrees Celsius, though heat waves can push readings several degrees higher.

The 0% crowd probability reflects the market's nascent stage rather than any meteorological certainty. Historical July data from Incheon shows considerable year-to-year variance: the station recorded 34.2°C on 14 July 2018 and 31.8°C on the same date in 2019, illustrating the 2–3 degree swings common to Seoul's summer weather. El Niño and La Niña patterns influence East Asian summer temperatures, as do the timing and intensity of the East Asian summer monsoon, which typically peaks in July. Traders should monitor Korea Meteorological Administration forecasts released in early July 2026, particularly any heat wave warnings or anomalous pressure systems developing over the Korean peninsula in the weeks preceding settlement.

From a regulatory standpoint, this weather derivative falls within the remit of the German GlüStV if offered to German residents, whilst US CFTC jurisdiction applies to US persons regardless of location. Most prediction market platforms operating under no-KYC thresholds—typically up to $1,500 notional exposure per trader—treat weather contracts as exempt from enhanced customer verification, provided individual positions remain below those limits. Traders should verify their platform's specific KYC policy and jurisdictional compliance framework before placing orders.

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 Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal UK?

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 Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
