Capital One Discover Merger: A New Era in U.S. Credit Card Market
In a landmark move, Capital One’s $35.3 billion acquisition of Discover Financial Services has received final regulatory approval and is set to close on May 18, 2025. This deal isn’t just about numbers—it marks the formation of the largest credit card issuer in the United States, with over $250 billion in outstanding balances.

Regulatory Green Light Granted
Both the Federal Reserve and the Office of the Comptroller of the Currency (OCC) have officially cleared the merger. However, Discover must fulfill existing compliance measures, including resolving enforcement actions related to customer overcharging between 2007 and 2023. A $100 million fine and a reimbursement plan are part of Discover’s obligations before integration.
