Highest temperature in Seoul (Incheon) on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Incheon International Airport Station will fall into one of several defined ranges, measured in degrees Celsius and sourced from Weather Underground's Daily Observations table rather than summary forecasts. Seoul's summer climate typically peaks in late July and early August; by mid-to-late August, diurnal temperatures often moderate slightly as the monsoon season transitions. The 0% crowd probability suggests either extreme confidence in a specific temperature band or insufficient liquidity in competing ranges.

Historical August temperature data from Incheon shows the airport station regularly records highs between 28–32°C during this period, with occasional excursions above 33°C during heat waves. The 2023 and 2024 summers saw elevated temperatures across East Asia, though August typically experiences more variable conditions than July. Comparable markets on seasonal temperature outcomes in temperate zones have resolved within tight ranges when settlement sources are clearly specified, as they are here via Weather Underground's Daily Observations methodology.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under Germany's GlüStV framework, prediction markets on weather outcomes may qualify as exempt from full licensing if structured as information markets rather than wagering products. US CFTC oversight generally exempts weather derivatives meeting specific criteria, though US traders should verify their state's position. Platforms offering no-KYC access up to $1,500 notional exposure typically operate under exemptions for small-value contracts; traders should confirm their broker's compliance posture before entry, as regulatory treatment of temperature prediction markets remains fragmented across jurisdictions.

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.

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