Highest temperature in Seoul on July 12?

Platform comparison

Market context

The market resolves on the peak Celsius temperature recorded at Incheon International Airport on 12 July 2026, a date that coincides with the monsoon season’s peak humidity in South Korea. Historical data indicates July is the rainiest month, yet clear spells can drive midday temperatures near or above 34°C, with recent records showing western cities topping 40°C in July [3][6]. The current 0% crowd-implied probability for a specific low outcome appears inconsistent with the 79% market weighting for “34°C or higher” and 18% for “33°C”, suggesting traders expect a hot day despite the rain risk [1].

Traders should monitor the Korea Meteorological Administration’s short-range forecasts for the 12 July window, particularly the 9 AM to 5 PM high temperature updates, as clear skies following rain bursts often trigger rapid heat spikes [8]. Recent repricing in adjacent Seoul July 11 markets, which surged to 97.4% for 32°C within 24 hours, signals that temperature forecasts can shift dramatically based on real-time atmospheric data [10]. The settlement relies on Wunderground’s Incheon station record, making localised airport conditions the critical dependency rather than broader Seoul city averages.

Regulatory access hinges on jurisdiction: German GlüStV restrictions may block participation for residents unless the platform qualifies under state licensing, while US CFTC reach extends to markets deemed gambling contracts, potentially limiting access for US traders. The “no-KYC up to $1,500” feature allows anonymous entry for smaller positions, enhancing accessibility for international users but not exempting them from underlying tax or reporting obligations in their home country. This structure balances privacy with compliance thresholds, though users must verify local legality before trading.

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.

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.
