Visa, Mastercard, Amex, Discover purchase volume in the U.S. 2010-2022
Visa's market share in the U.S. especially increased during the coronavirus pandemic, mostly as Americans used more debit cards. The growing use of debit cards in the U.S. may explain why the market share of American Express declined compared to the other schemes.
Mastercard's purchase volume in the United States increased by roughly 240 billion dollars in 2022, which was less than Visa's increase.
