Highest temperature in Seoul on July 10?

Platform comparison

Market context

The underlying event is the peak daily temperature recorded at Incheon International Airport on 10 July 2026, which will determine the settlement of this prediction market. Historical data shows Seoul reached 37.8°C on 8 July, the highest ever recorded during the 1–10 July window since records began[1]. Long-term averages for early July in Seoul hover around 28°C, with daily highs typically ranging between 21°C and 30°C[3][6][8]. The current crowd-implied probability of 0% for higher temperature ranges suggests traders believe a record-breaking heatwave beyond 37.8°C is unlikely, despite the monsoon season’s humidity often making temperatures feel over 34°C[5].

Traders should monitor real-time weather updates from Wunderground and short-range forecasts from the Korea Meteorological Administration, as sudden rain showers or cloud cover could suppress peak temperatures[9]. Recent reports confirm July is the rainiest month in South Korea, with concentrated heavy rainfall likely to interrupt heat accumulation[5]. The settlement window ends 12:00 UTC on 10 July 2026, meaning any late-afternoon temperature spike must be captured before this deadline[1].

Regulatory accessibility hinges on jurisdiction: German GlüStV rules may restrict participation for residents without proper licensing, while US CFTC reach could impose compliance burdens on platforms offering unregistered derivatives[1]. However, platforms offering “no-KYC up to $1,500” allow traders to access this market without identity verification, provided the bet size remains within that threshold. This feature enhances accessibility for international users but does not exempt them from local tax or regulatory obligations.

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 Tax UK has a different geo footprint.

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 Tax 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?
