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. Is Polymarket Legal in Canada has a different geo footprint.
Do I need to KYC for Is Polymarket Legal in Canada?
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.
Can I trade anonymously?
Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada 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. Is Polymarket Legal in Canada 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), Is Polymarket Legal in Canada would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
