Highest temperature in Seoul (Incheon) on August 13?

Platform comparison

Market context

On 13 August 2026, Seoul's Incheon International Airport will record a daily maximum temperature in Celsius. This market resolves to whichever temperature band contains the highest reading logged in Weather Underground's Daily Observations table for that station on that date. The 0% crowd probability reflects either extreme confidence in a specific range or sparse trading activity; historical August highs at Incheon cluster between 28–32°C, making the full spectrum of plausible outcomes wide enough that any single narrow band should carry non-trivial probability mass.

August in Seoul typically brings humid subtropical conditions with occasional typhoon influence. The Korea Meteorological Administration publishes forecasts 10 days ahead with reasonable skill; any tropical cyclone track toward the Korean peninsula in early August 2026 would suppress daytime maxima, whilst high-pressure systems anchored over the region tend to drive readings toward the upper end of the seasonal range. Traders should monitor KMA advisories and typhoon warnings from the Japan Meteorological Agency in the week preceding settlement, as these remain the primary drivers of daily extremes.

From a regulatory standpoint, this market falls under the German GlüStV framework if accessed from Germany, where prediction markets on weather require appropriate licensing. US CFTC oversight applies to US persons, though weather derivatives on non-financial indices typically face lighter scrutiny than equity or commodity contracts. Platforms offering no-KYC access up to €1,500 (approximately $1,500) allow retail participation without identity verification below that threshold, though settlement and withdrawal may trigger subsequent verification depending on jurisdiction and operator policy.

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 Germany Legal has a different geo footprint.

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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Germany Legal 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.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
