FinanceMarket cap $35B3 connections

Discover Financial operated America's fourth-largest credit card network before Capital One completed its $35.3B acquisition in May 2025. The combination created the largest US credit card issuer by loan balances. Discover's proprietary payment network - the only major US card network not operated by Visa or Mastercard - gives Capital One rare independence from the card duopoly and significant fee savings.
