Biggest card issuers - credit cards and debit cards - in the U.S. 2023
Published by
The top five card issuers in the United States were responsible for 41 percent of the market, with three issuers taking up one-third of card transaction value. This is according to a publication from September 2024, that quoted data for the United States in 2023. Note that the figures display card payments as a whole, and do not distinguish between credit cards or debit cards. Visa ranks as the United States' biggest card scheme, but its market share has slowly declined since 2020 in favor of American Express.
