Discover Financial Services's Growth & Acquisition Strategy

Before the deal, Discover had pulled back on new account growth while it fixed compliance problems. Under Capital One the strategy has shifted to network scale: migrating Capital One debit cards to Discover (about 25 million done by mid-2026), testing Capital One credit cards on the network, and widening acceptance abroad.

How Discover Financial Services Makes Money

Discover makes money two ways. As a bank, it lends to consumers through Discover-branded credit cards and personal loans and earns net interest income on those balances, funded largely by online savings and CD deposits rather than branches. As a network, it earns discount and interchange revenue when merchants accept Discover cards and processing fees when banks route debit and ATM transactions over PULSE. Unlike Visa and Mastercard, which do not lend, Discover keeps both the lending spread and the network economics on its own cards. Interest income on card loans is by far the largest piece.
