Why the check comes first
KYC verification is required to comply with federal identity and anti-money-laundering (AML) rules, and Polymarket US is a Commodity Futures Trading Commission (CFTC)-regulated exchange. Its partner documentation says it uses Socure as its identity verification provider and lists four outcomes: instant approval, document verification, manual compliance review, and rejection, where a rejected participant cannot trade.
If the check stalls
The first reason Polymarket US gives for putting an account under review is an information mismatch or missing details, so entered details are the first thing to check. Can't verify your identity on Polymarket US covers a stalled check in full.
