Highest temperature in Seoul on July 13?

Platform comparison

Market context

The market tracks the peak temperature at Incheon International Airport on 13 July 2026, a metric that determines settlement for the Seoul heat prediction. With the crowd-implied probability for a "YES" outcome at 0%, traders currently bet against any specific threshold being breached, despite Seoul reaching 37.7°C in early July 2025, the hottest reading in 117 years for that period [6]. Historical data shows July highs in Seoul typically range between 31°C and 35°C, rarely exceeding 35°C, while the nation recently recorded a record 41.0°C in Hongcheon, indicating the region’s growing heat volatility [4][5]. The current 0% probability likely reflects a lack of consensus on a specific temperature range rather than an expectation of cold weather, as 32°C holds the highest market share at 42% [1].

Traders should monitor daily forecasts from the Korea Meteorological Administration and real-time updates on Wunderground, the designated resolution source, for anomalies in the Incheon station data [1]. The settlement window closes at 12:00 UTC on 13 July 2026, meaning any temperature spike before this deadline will trigger resolution. Recent reports of 22 consecutive "tropical nights" in Seoul during July 2025 suggest sustained heatwaves are a recurring catalyst for extreme readings [3].

Regulatory clarity remains the primary constraint for accessibility. The German GlüStV imposes strict licensing for betting operators, while the US CFTC maintains reach over prediction markets offering binary outcomes to US residents. The "no-KYC up to $1,500" feature allows users to access this weather market without identity verification for smaller stakes, bypassing immediate compliance hurdles but not exempting the platform from broader regulatory oversight under international tax and KYC frameworks.

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK 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.
