BlockBeats reported on Sept. 20, citing The Wall Street Journal, that prediction-market platform Polymarket struggled to contain debit card fraud as it rapidly scaled its U.S. operations. In February, the payment processor handling debit card transactions for Polymarket's U.S. platform identified a wave of fraud in which stolen debit cards were linked to user accounts to place bets and route withdrawals to accounts controlled by the perpetrators.
