Market context
The event is whether the **highest temperature at Toronto Pearson** on 2 August 2026 lands in the market’s chosen Celsius band, using the day’s maximum reading from Wunderground’s historical page for the airport station. August in Toronto is usually warm rather than extreme: the city’s long-run average high for the month is about **26.1°C**, while the record August day high is **38.9°C**. [1]
That combination matters because the current **0% YES** implies the crowd sees the listed range as effectively unreachable, but August climatology still leaves room for notable heat spikes. Historical Toronto temperature records show that early August can produce highs in the low 30s, including a **33.9°C** record for 2 August in one Toronto dataset, and recent August daily highs have often reached the mid-to-high 20s, with occasional low-30s readings. [1][4] For market reading, the key point is that a single hot afternoon at Pearson can move the settlement outcome, even if the month starts with a modest seasonal baseline. [1][9]
From a regulatory and access angle, German **GlüStV** treatment of online wagering can affect whether a user can participate through local restrictions, while the US **CFTC** frame is relevant because event markets with commodity-style or derivatives characteristics may face US access limits. “**No-KYC up to $1,500**” means a user can typically trade or withdraw within that ceiling without completing full identity verification, which improves access for small positions but does not remove jurisdictional blocks or platform-specific controls on this market.

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.
- 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.
- 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.
- 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).
- 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.
