Dominating the Wallet: The 8 Largest Credit Card Issuers in the United States
Understanding the Landscape: Issuers vs. Networks
Before diving into the rankings, it helps to distinguish between a card network and a card issuer:
-
Payment Networks (like Visa and Mastercard) provide the digital payment rails that process transactions between merchants and banks.
-
Card Issuers (the banks listed below) extend the credit line, set interest rates, approve applicants, and fund rewards programs. Note that American Express and Discover operate as both issuers and independent payment networks.
