Highest temperature in Busan on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Gimhae International Airport Station in Busan will be measured and reported via Weather Underground's Daily Observations table. The market resolves to the temperature range bracket containing that peak reading in degrees Celsius. Busan's August climate typically produces daily highs between 28–32°C, though extreme heat events have pushed readings above 34°C in recent summers across South Korea's southern coast.

The 0% crowd probability reflects the market's nascent state rather than any meteorological certainty. Historical August temperatures at Gimhae show considerable year-to-year variance; the Korea Meteorological Administration recorded 34.5°C on 15 August 2019 and 31.2°C on the same date in 2023. Traders should note that coastal location and sea-breeze patterns create volatility in daily maxima that inland stations do not exhibit. Comparable Korean airport weather markets have typically seen probability distributions flatten as settlement approaches, suggesting current pricing may not yet reflect seasonal baseline expectations.

From a regulatory standpoint, this market falls within accessible parameters for most EU and UK traders. Under German GlüStV provisions, prediction markets on weather events are generally exempt from gaming licensing if they meet transparency and settlement criteria—which this market's explicit Weather Underground sourcing satisfies. US CFTC reach extends to US persons, though weather derivatives themselves occupy a narrower regulatory footprint than financial contracts. The no-KYC threshold of $1,500 USD on many platforms means traders can establish positions without identity verification up to that stake level, though individual platform policies vary. Settlement window closure on 15 August 2026 at 12:00 UTC aligns with typical meteorological reporting schedules, though traders should confirm their platform's exact data-pull timing against Gimhae's observation schedule.

UK Frequently Asked Questions

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.

Is Polymarket regulated by the UKGC?

No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.

What are the HMRC tax rules on Polymarket profits for UK traders?

Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT). For 2026/27, the CGT rate is 18% (basic rate) or 24% (higher rate). The annual CGT exemption is £3,000. Report via HMRC Self Assessment if your total crypto gains exceed £3,000 or proceeds exceed £50,000.

Does Polymarket KYC apply to UK users?

Yes. Polymarket requires KYC (Know Your Customer) verification for all users, including UK residents. You must provide a government-issued photo ID and a selfie. The process typically takes 5–10 minutes via their ID verification provider.

What is the legal difference between Polymarket and Betfair Exchange for UK traders?

Betfair Exchange is UKGC-licensed, meaning UK consumer protections apply and winnings are typically tax-free. Polymarket is not UKGC-licensed — it operates under decentralised blockchain rules. Profits from Polymarket are subject to HMRC CGT as crypto disposals. Choose based on your regulatory preference and tax situation.
