Highest temperature in Seoul on July 12?

Platform comparison

Market context

The market hinges on whether Seoul’s Incheon International Airport records a temperature exceeding the current settlement threshold on 12 July 2026, with the crowd currently assigning zero probability to a “YES” outcome. Historical July data for Seoul shows average highs around 28°C, though extremes have previously reached 41.2°C during record-breaking heatwaves in 2025, indicating that while typical conditions are moderate, anomalous spikes remain possible [2][5].

Comparable cases from recent years show that July in South Korea falls within monsoon season, bringing high humidity and frequent rain that often suppress peak temperatures, yet sudden clear-sky heat events can still push readings above 30°C [4][6]. The current 0% probability likely reflects the statistical weight of monsoon-driven cooling, but traders should monitor the Korea Meteorological Administration’s short-range forecasts for any sudden shifts toward sustained high-pressure systems that could trigger extreme heat [9].

Regulatory accessibility is shaped by German GlüStV rules, which restrict unlicensed prediction markets, and US CFTC jurisdiction, which may classify such instruments as derivatives requiring compliance. The “no-KYC up to $1,500” feature allows limited access for users avoiding identity verification, but this does not override cross-border legal obligations; traders must assess their local regulatory environment before participating, as enforcement varies by jurisdiction and market structure.

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. Is Kalshi Legal in California has a different geo footprint.

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

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).
