Highest temperature in Seoul on July 14?

Platform comparison

Market context

Seoul's highest temperature on 14 July 2026 will be measured at Incheon International Airport weather station and resolved via historical records on Weather Underground. July in Seoul typically sees daytime highs between 28–32°C, though heat waves can push readings above 35°C. The settlement window closes at noon UTC on that date, meaning the resolution source captures the full calendar day's peak temperature in Seoul's metropolitan region.

Historical July temperature data from Incheon shows that extreme heat (above 35°C) occurs in roughly 30–40% of years during mid-July, whilst readings below 25°C are rare. The 0% crowd probability suggests traders currently expect a narrow range outcome; however, this reflects uncertainty about which specific temperature bracket will resolve, not an absence of heat. Recent summers in South Korea have seen intensified heat waves linked to Pacific high-pressure systems, with 2023 recording multiple days above 33°C in early July. The Korea Meteorological Administration publishes seasonal forecasts in June that can shift market expectations materially.

From a regulatory standpoint, this weather derivative falls under different jurisdictions depending on trader location. UK residents trading on platforms operating under the Gambling Commission face no specific KYC threshold for weather markets, though platforms may impose internal limits. German traders should note that prediction markets on non-financial events may fall outside GlüStV (gambling licensing) scope if structured as information contracts rather than wagering products. US CFTC oversight applies only if the platform itself operates from US territory or targets US persons; most offshore prediction markets operate in a regulatory grey zone for US traders. No-KYC access up to $1,500 typically means traders can deposit and trade without identity verification below that threshold, though withdrawal and account closure may later trigger verification requirements under anti-money-laundering rules.

FAQ

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Tax 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.

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.

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.

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 Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
