Highest temperature in Seoul on July 28?

Platform comparison

Market context

Seoul's peak temperature on 28 July 2026 will be measured at Incheon International Airport's weather station and reported in Celsius. The settlement hinges on Wunderground's historical data feed for that specific date, with the resolution window closing at midday UTC. The 0% crowd probability suggests traders are either absent from this market or treating it as a placeholder pending closer approach to the event date.

July temperatures in Seoul routinely exceed 30°C, with historical highs in the 33–37°C range during peak summer. Comparable July days at Incheon station show that extreme heat events (above 35°C) occur in roughly one-third of years, whilst readings below 28°C are rare. The current zero probability likely reflects the market's early stage rather than any expectation of anomalous cold; as the date approaches, traders will calibrate against seasonal norms and any emerging weather forecasts.

Regulatory access to this market depends on jurisdiction. Under German GlüStV rules, prediction markets operating without a licence face restrictions on marketing to German residents, though trading itself may proceed. US CFTC oversight applies to derivatives on real-world events; this weather contract falls outside direct CFTC jurisdiction if structured as a prediction market rather than a leveraged bet. Many platforms offer KYC-free trading up to $1,500 notional exposure per user, which would cover modest positions on this market without identity verification, though higher stakes require full compliance documentation.

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.

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.

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