Highest temperature in Seoul on July 24?

Platform comparison

Market context

The underlying event is the **highest temperature recorded at Incheon Intl Airport Station on 24 July 2026**, which is the figure Wunderground uses for settlement, rather than a city-centre Seoul reading. That distinction matters because airport observations can differ from the broader metropolitan area, and the market is tied to a single official daily maximum rather than a forecast average[2].

The current **0% YES** implied probability is best read against a late-summer climatology that is usually warm but not fixed at one level. Seoul in July typically sees highs around 30°C, while recent reporting on 24 July points to rain over the capital area and surrounding Incheon/Gyeonggi, alongside widespread daytime heat and maximum apparent temperatures above 33°C[1][2]. For a range market, that mix means the final print can easily land in a neighbouring band if showers suppress the airport high for much of the day, even when the wider region feels hot[2][4].

From a market-access perspective, the main frictions are regulatory and operational rather than meteorological. Under Germany’s **GlüStV**, prediction-market activity can face gambling-law treatment depending on the product structure, so German access may be constrained; in the US, the **CFTC** can assert reach where a contract is viewed as a commodity derivative or event contract, which is why venue terms and jurisdictional screening matter. A stated **“no-KYC up to $1,500”** limit means smaller positions may be possible without full identity checks, but it does not guarantee access from every jurisdiction or remove wallet, sanctions, or platform-level geoblocks; for this market, that chiefly affects who can reach the order book, not the weather settlement itself.

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.

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.

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