Highest temperature in Seoul on July 15?

Platform comparison

Market context

Seoul is set to record its peak daytime heat on 15 July 2026 at the Incheon International Airport station, with the market betting on whether that figure falls within a specific Celsius range. The current crowd-implied probability of 0% YES suggests traders believe the temperature will exceed the upper bound of the offered range, likely reflecting expectations of a hot summer day typical for mid-July in the Korean capital.

Historically, Seoul’s highest temperatures in mid-July often reach between 33°C and 37°C, with 2023 seeing a peak of 38.4°C at Incheon Airport during a prolonged heatwave. Comparable years like 2018 and 2022 also recorded highs above 36°C, framing the 0% probability as a reaction to consistent seasonal patterns rather than an outlier forecast.

Traders should monitor the Korea Meteorological Administration’s weekly heatwave bulletins and any sudden shifts in monsoon activity, which can suppress temperatures. A recent report from Yonhap News noted that forecasters are warning of elevated heat risks across the Seoul region through mid-July due to weak cloud cover and high-pressure systems [1]. Regulatory clarity remains key: German GlüStV rules may restrict access for EU users, while US CFTC oversight could affect US participants. The “no-KYC up to $1,500” threshold means this market remains accessible to small traders without identity verification, provided they stay under that limit, enhancing liquidity for retail-sized positions.

FAQ

How are winnings taxed?

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legal in California exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

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).
