Fraudsters linked stolen debit cards to thousands of Polymarket accounts in $10 million scheme
Fraudsters linked stolen debit cards to thousands of Polymarket accounts in a $10 million scheme, according to Yahoo Finance and The Block. Polymarket's U.S. customer documentation lists debit cards and bank transfers as funding methods. The incident follows a recent Wall Street Journal report alleging CEO Shayne Coplan dismissed internal fraud concerns during a growth push. Polymarket is currently seeking a $1 billion raise at a $21 billion valuation.
The $10 million fraud attempt lands during Polymarket's $21 billion valuation push and just after the Wall Street Journal reported that CEO Coplan dismissed internal fraud warnings. Investors in any billion-dollar raise will now demand audited payment controls before committing capital. The CFTC already has a fraud probe open; this case gives investigators a concrete example of where existing safeguards failed at scale.
Competitor Kalshi holds more funding and has moved faster on sports products this season. Polymarket cannot afford a capital freeze or a lengthy consent order while that gap widens. The episode also tests the argument that retail clearinghouse protections substitute for mandatory futures broker oversight. If the CFTC disagrees, the platform's lighter regulatory structure becomes a costly burden overnight.
