Highest temperature in Seoul (Incheon) on August 7?

Platform comparison

Market context

The underlying event is the day’s **highest recorded temperature** at Incheon International Airport Station on 7 August 2026, with settlement based on the Wunderground daily-history entry for that station. Forecasts around Seoul for 7 August point to extreme heat: SBS reports a daytime high near **39°C**, with heatwave warnings expanded across the Greater Seoul area, while AccuWeather’s August outlook still places Seoul’s typical daily highs mostly in the **81–88°F** range, underscoring how far above average today’s setup is.[2][1]

For market reading, a **0% YES** implies the crowd is effectively pricing the event as unresolvable into the specified bucket or outside the likely temperature band, but that is not the same as certainty on the weather itself. Comparable August Seoul data normally sits around the low-to-mid 30s Celsius at most on forecast models, and historical August averages are far lower, so the main question is whether Incheon Airport catches the same hot air mass as inland Seoul or is moderated by marine influence and local cloud or rain.[3][12][19]

A trader should watch the **official hourly progression**, any late-day rain or thunderstorm development, and whether the airport station reports a short-lived peak before cooling sets in, because the settlement uses the *highest* reading of the day rather than the noon or evening value. On access, German users face the broader **GlüStV** issue: if the platform is treated as offering gambling-like products, domestic availability can be restricted regardless of the market itself; in the US, the **CFTC’s reach** matters because event contracts can fall under derivatives scrutiny depending on structure and availability. “No-KYC up to $1,500” means a user may be able to deposit, trade, or withdraw within that cap with lighter identity checks, but it does not remove geoblocking, sanctions screening, or venue-level limits on who can access this specific weather market.

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).
