Highest temperature in Seoul on July 5?

Platform comparison

Market context

On 5 July 2026, the real-world event determining this market’s outcome is the highest temperature recorded at Incheon International Airport, with Seoul’s early-July heat historically reaching extremes that defy typical monsoon expectations. While July in South Korea is generally hot and humid with average highs near 30°C, the rainy season (Jangma) often suppresses peak temperatures, yet record-breaking heatwaves have occurred even during this period [1][2].

Historical precedents frame the current 0% crowd-implied probability as potentially premature: in early July 2023, Seoul recorded 37.8°C, the highest early-July temperature ever, beating a 117-year record [9][10]. Such anomalies demonstrate that monsoon clouds do not guarantee cooler days, and traders should weigh the possibility of a sudden heat spike against the prevailing damp narrative, especially given Incheon’s coastal location which can amplify or mitigate extremes depending on wind patterns [1][6].

Traders must monitor the Korea Meteorological Administration’s short-range forecasts for sudden shifts in cloud cover and precipitation probability, as well as any announcements regarding the Sinchon Water Gun Festival, which could influence local humidity and temperature readings [1][4]. Recent reports of record heat and torrential rains predicted for Korea this summer underscore the volatility of seasonal weather patterns, making real-time data from Wunderground critical for assessing whether a 37°C+ day remains feasible [7].

From a regulatory standpoint, German GlüStV implications and US CFTC reach define the market’s legal boundaries, while the “no-KYC up to $1,500” threshold ensures accessibility for retail participants without intrusive identity verification, provided they comply with local tax obligations [1]. This specific market’s structure allows broad participation under current frameworks, though traders should remain aware that settlement depends solely on verified Wunderground data, not speculative forecasts.

The market resolves based on the highest temperature recorded for all times on 5 July 2026 at Incheon Intl Airport Station, with settlement ending 2026-07-05T12:00:00Z, ensuring a clear, data-driven outcome independent of external interpretations [1].

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 Polymarket Legal in Canada 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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

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), Is Polymarket Legal in Canada would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
