Market context
Taipei Songshan Airport is hot enough already for the market to sit around the day’s likely maximum rather than an open-ended weather swing. With the crowd giving **36°C** the dominant outcome at **93%** and **37°C or higher** still priced at **5%**, the book is effectively saying the distribution is tightly clustered in a narrow band, which is typical when the forecast points to persistent summer heat rather than a sharp frontal change.[1]
For context, this is the sort of market where the final print is usually driven less by a single dramatic weather event and more by the timing of the daily peak at the official station. Comparable summer temperature markets in Taipei tend to resolve near the upper-middle of the forecast range when conditions are sunny, humid and lightly windy, because the day’s maximum is often reached mid- to late-afternoon rather than early in the morning.[1][3] A zero per cent “YES” price is therefore not a statement that the event cannot happen, but that traders see no meaningful value in the offered band at present, especially given the market’s resolution rule is the highest recorded temperature at Taipei Songshan Airport on the day.[1]
From a market-access standpoint, the main regulatory filters are practical rather than meteorological: German participation can be affected by GlüStV gambling rules, US users may face CFTC-related restrictions depending on platform structure, and “no-KYC up to $1,500” generally means smaller accounts can trade without identity checks until cumulative activity crosses that threshold, after which verification is typically required. For this contract, that matters because the settlement source is a single public weather-history page, so accessibility turns on account eligibility and limits rather than any bespoke data dependency; the key catalyst remains the live local forecast and whether Taipei’s afternoon heat peaks above the 36–37°C band before the station’s daily maximum is locked in.[1][3]

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 Legal UK has a different geo footprint.
- 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. Polymarket Legal UK 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.
- What happens during a tax audit?
- You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
