Highest temperature in Seoul on July 28?

Platform comparison

Market context

Seoul's summer temperatures in late July routinely exceed 30°C, with historical highs near 35–37°C during heat waves. The settlement will depend on the maximum temperature recorded at Incheon International Airport's weather station on 28 July 2026, converted to Celsius via Wunderground's historical database. This particular date falls within South Korea's peak summer season, when Pacific high-pressure systems and warm southwesterly flows from the continent drive sustained heat across the peninsula.

The 0% crowd probability reflects the market's early stage and the inherent difficulty in forecasting a specific temperature range six months ahead. Comparable July weather patterns from 2020–2024 show considerable year-to-year variance: some years produced peaks around 32–34°C, whilst others saw brief spikes above 36°C during exceptional heat events. The Korea Meteorological Administration publishes seasonal outlooks in June that traders should monitor for El Niño or La Niña signals, which influence East Asian summer circulation patterns and can shift temperature distributions by 1–3°C. Recent reporting from the KMA (June 2024 outlook) indicated that Pacific warming trends may favour above-normal temperatures across the Korean peninsula during summer 2026, though such forecasts carry substantial uncertainty at the six-month horizon.

From a regulatory standpoint, this market operates under different frameworks depending on trader location. EU residents face scrutiny under Germany's GlüStV (gambling licensing statute), which classifies prediction markets as financial instruments requiring authorisation; UK traders post-Brexit encounter the Gambling Commission's remit over betting exchanges. US CFTC jurisdiction applies to derivatives on physical commodities or events, though weather derivatives occupy a grey zone. Platforms offering no-KYC access up to $1,500 typically serve jurisdictions with lighter-touch oversight, but traders should verify their own residency rules before participation.

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California 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.

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.
