Highest temperature in Seoul (Incheon) on August 11?

Platform comparison

Market context

Seoul's summer temperatures regularly exceed 30°C, with August typically the hottest month. The highest temperature recorded at Incheon International Airport on 11 August will determine the settlement range. Historical August maxima at the station have reached 34–36°C in recent decades, though extreme heat events pushing towards 37–39°C occur roughly once per five to ten years during particularly intense heat waves. The 0% crowd probability suggests traders expect either a data-resolution issue or an unusually cool day for the season, both statistically unlikely given the airport's thermal profile.

Comparable August temperature markets in East Asia show that crowd-implied probabilities near zero typically reflect either settlement mechanism uncertainty or extreme confidence in a narrow outcome band. The Weather Underground Daily Observations table—the specified resolution source—occasionally diverges from summary figures by 0.5–1.0°C due to sensor timing and averaging methodologies. Traders should verify the exact station identifier and confirm Wunderground's historical recording practices for Incheon before committing capital.

From a regulatory standpoint, this market falls under German GlüStV provisions if accessed from Germany, where prediction markets require operator licensing. US CFTC reach extends to US persons regardless of operator location; binary weather markets typically escape derivatives classification if they settle on objective, verifiable data. The "no-KYC up to $1,500" threshold applies here: positions below that notional value generally avoid identity verification on compliant platforms, though operators may impose stricter limits. Traders should confirm their jurisdiction's stance on weather derivatives before entry.

FAQ

Do I need to KYC for Is Kalshi Legal in California?

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.

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.

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