Highest temperature in Busan on July 28?

Platform comparison

Market context

On 28 July 2026, the highest temperature recorded at Gimhae International Airport Station in Busan will settle this market into one of several defined ranges. The resolution will draw from Weather Underground's historical data for that specific date and location, with the settlement window closing at 12:00 UTC. Busan's summer climate typically produces daily highs between 28–32°C in late July, though heat waves can push readings several degrees higher. The current crowd probability of 0% for any single outcome suggests either incomplete market formation or uncertainty about which temperature band will ultimately contain the day's peak.

Comparable July temperature records for Busan show considerable year-to-year variation. Between 2015 and 2024, recorded highs on or near 28 July ranged from 29°C to 34°C, with extreme heat events in 2018 and 2023 reaching the upper end of that distribution. This historical spread indicates that traders cannot safely anchor to a single expectation; the market's current flat probability distribution reflects genuine climatic volatility rather than data scarcity. South Korea's meteorological authority publishes seasonal forecasts in early summer, and the Korea Meteorological Administration typically issues heat advisories 3–5 days ahead of significant warming events.

From a regulatory standpoint, this market's accessibility varies by jurisdiction. Under German GlüStV rules, prediction markets on weather outcomes face stricter licensing requirements than political or sports markets. US CFTC oversight applies to derivatives on weather indices, though single-location temperature contracts occupy a grey zone. Most European platforms, including those compliant with UK Gambling Commission standards, permit participation without KYC verification up to £1,200–£1,500 cumulative exposure, making entry-level positions in this Busan temperature market accessible to casual traders without formal identity verification.

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 Tax UK has a different geo footprint.

Do I need to KYC for Polymarket Tax UK?

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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax 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.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
