American Express issues credit and charge cards to consumers, small businesses, mid-sized companies and large corporations around the world, plus travel, dining and expense management services. It also offers savings and checking accounts, consumer installment loans and small-business lines of credit. It runs its own payments network and signs up merchants to accept its cards, charging them a fee it calls the discount rate. Banks and other institutions in approximately 110 countries and territories also issue American Express-branded cards or sign up merchants on its network.
American Express says it makes money mainly from spending on its cards and secondarily from finance charges and fees, including annual fees on many cards. It reports four segments: U.S. Consumer Services, Commercial Services, International Card Services, and Global Merchant and Network Services. In 2025 spending on the cards it issues came to $1,670 billion, and at year-end it had 86.6 million of its own cards in force. Delta Air Lines is its largest partner; cards issued with Delta made up approximately 13 percent of that worldwide spending as of December 31, 2025.
Its card network competes with Visa, China UnionPay, Mastercard, JCB, Discover and Diners Club International, and it says it is the fourth largest general-purpose card network globally by purchase volume. Other cobrand partners include Marriott International, British Airways and Hilton. As of December 31, 2025, it employed approximately 76,800 people, approximately 25,900 of them in the United States.
