Polymarket, the American platform, suffered debit card fraud, and the CEO stated that they will continue to grow despite paying fines

In February, a company that handles debit card transactions for Polymarket's U.S. betting platform reported that fraudsters are flooding the app. Users are linking stolen debit cards to their Polymarket U.S. accounts, attempting to place bets and withdraw funds to clean cards or accounts under their control, with thieves trying to make off with at least $10 million.

The processor once rejected over 80% of deposits as fraudulent, far exceeding the industry standard of about 1%. Polymarket employees raised concerns to CEO Shayne Coplan. Insiders said the compliance team's response to Coplan was shocking: continue to grow, and if regulators find out, just pay the fines.
