Highest temperature in Seoul (Incheon) on August 10?

Platform comparison

Market context

The real-world event is the **highest temperature recorded at Incheon Intl Airport Station on 10 August 2026**, converted into the market’s Celsius outcome bands. The market’s wording matters: settlement is tied to Weather Underground’s **Daily Observations** table, not the site’s Day High & Low summary, so a late-day reading in the observation log can decide the result even if the summary panel looks different.[7][15]

Historically, August around Seoul and Incheon is firmly within the region’s warm season, with Seoul’s August mean maximum around **30.0°C** and record highs reaching **39.6°C** in the capital during severe heat events.[9][10] That helps explain why the crowd can treat mid-30s Celsius outcomes as plausible in peak summer, even though the current market at **0% YES** suggests traders have not assigned material probability to any particular band yet.[5][7] Because the market resolves on Incheon airport observations rather than generic Seoul weather, comparable Seoul heat records are useful context but not a substitute for the airport-specific reading.[7][15]

For accessibility, this is mainly a venue-and-compliance question rather than a weather one. In Germany, the GlüStV framework can affect whether gambling-like products are usable or marketable to domestic users, while US CFTC reach matters because the product resembles a weather derivative-style event contract and may be restricted for US persons depending on platform policy and structure. If the venue offers “no-KYC up to $1,500”, that generally means small-volume participation may be possible without identity verification, but it does not remove geo-restrictions, withdrawal checks, sanctions screening, or the chance that the platform blocks certain jurisdictions altogether.

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 Legit has a different geo footprint.

Do I need to KYC for Is Kalshi Legit?

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit 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.

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).
