American Express Company

AI Summary

American Express runs a closed-loop payment network where it issues cards directly to consumers and businesses, and also processes transactions at merchants who accept those cards [COMPANY OVERVIEW]. They earn revenue from cardmember fees, interest on balances, merchant discount fees (what stores pay to accept Amex), and other travel and lifestyle services bundled with their premium cards [COMPANY OVERVIEW]. Unlike Visa or Mastercard, Amex controls both sides of the transaction — the cardholder relationship and the merchant relationship — which gives them higher profit margins but also limits acceptance compared to competitors.
