Polymarket's international platform does not ask most users for identity documents to sign up: you connect or create a wallet and trade, subject to its location checks, though its terms let it request verification. Polymarket US, the CFTC-regulated exchange, requires identity verification (KYC) for every user. Nimb never asks for identity documents; it checks Polymarket's location rules before every order.

Is using Polymarket without KYC legal?
Not needing ID is not the same as being allowed. Location rules still apply: the US, the UK, France and about 35 other countries are close-only, and getting round them with a VPN breaks Polymarket's terms. Who can trade · Are prediction markets legal?
Is it anonymous?
No, pseudonymous. Every trade and position from your Polymarket wallet is public on Polygon, and the exchange where you bought USDC knows who you are. Wallet lookup.
