Highest temperature in Seoul on July 11?

Platform comparison

Market context

Seoul faces a critical heat assessment on 11 July 2026, as the Incheon International Airport Station records its daily peak temperature to settle a prediction market with a current 0% implied probability for any outcome above the baseline. Historical data shows Seoul’s average July highs range between 27°C and 29°C, rarely exceeding 33°C, though recent extremes have shattered norms; July 2023 saw Seoul hit 37.8°C, the hottest early July in 117 years, while Hongcheon recorded an all-time national peak of 41.0°C in 2024[2][4]. This volatility frames the current 0% probability as a market mispricing, given that even conservative models suggest a non-trivial chance of temperatures surpassing 31°C, the current frontrunner at 37% probability[1].

Traders must monitor the Korea Meteorological Administration’s daily heatwave bulletins and Wunderground’s real-time station data, as the market resolves strictly on the Incheon Airport reading[1]. A recent Anadolu Ajansı report confirmed Seoul’s susceptibility to record-breaking early July heat, with 37.7°C recorded in 2023, reinforcing the risk of similar spikes this year[6]. The settlement window closes at 12:00 UTC on 11 July, meaning any pre-noon heat spike will lock the outcome.

Regulatory clarity remains pivotal for accessibility. Under Germany’s GlüStV, prediction markets face strict licensing if they resemble gambling, while the US CFTC asserts reach over any market with US participants, regardless of KYC. The ‘no-KYC up to $1,500’ threshold allows retail traders to access this market without identity verification, but only if the platform operates under a compliant jurisdiction. This specific market’s weather-based resolution avoids securities classification, yet cross-border tax obligations may still apply for profits exceeding local thresholds.

FAQ

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.

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.
