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. PolyGram 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. PolyGram 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. PolyGram 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), PolyGram would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
