Highest temperature in Seoul on July 23?

Platform comparison

Market context

The day’s outcome will be set by the highest temperature recorded at Incheon Intl Airport Station on 23 July, with the market resolving into whatever Celsius range matches the Wunderground history page for that station. The current crowd view is split around the high-20s, with **27°C** the frontrunner at 49% and **28°C** next at 30%, which is consistent with Seoul’s July climate profile rather than an outlier heat event.[1][2]

For context, Seoul’s July average high is about **28°C**, with substantial humidity and a meaningful rain chance, so outcomes in the 27–29°C band are historically plausible and should be read as a normal summer-weather distribution unless a heatwave shifts the terminal reading upward.[2] Markets like this often leave little room for precision because the resolution depends on the single highest reading during the day, so late-afternoon warming, cloud cover, or rainfall timing can matter more than the morning forecast.

For accessibility and compliance context, German users may be affected by **GlüStV**-related restrictions that can limit participation or platform access depending on operator status and local implementation, while the US **CFTC** can still matter where a contract is offered to or touches US persons, even if the event itself is weather-based. “**No-KYC up to $1,500**” generally means a user may be able to trade small amounts with lighter identity checks, which can make this market easier to access for low-stakes participation, but higher limits or withdrawals typically trigger standard verification steps.

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 Legal UK has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK 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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK 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 Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
