Discover Financial Services is a US credit card issuer, online bank and payment network founded by Sears in 1985 and headquartered in Riverwoods, Illinois. Capital One completed its acquisition of Discover on May 18, 2025. In 2024, its last full year as a public company, Discover reported $17.9 billion of revenue net of interest expense and $4.5 billion of net income.
Who owns Discover?
Capital One Financial (NYSE: COF) owns Discover. The all-stock deal was announced on February 19, 2024 at $35.3 billion and approved by the Federal Reserve and OCC on April 18, 2025. At closing, the fair-value purchase consideration was $51.8 billion. Discover shareholders received 1.0192 Capital One shares per share, and the DFS ticker was retired.
How Discover makes money
Most of Discover's revenue is net interest income on credit card loans, which totaled $102.8 billion at the end of 2024, plus interest on personal loans. It also earns merchant discount, interchange and processing fees on the Discover network, the PULSE debit and ATM network, and Diners Club International. Online savings accounts and CDs fund the loan book.
What changed under Capital One
By mid-2026 Capital One had moved about 25 million debit cards onto the Discover network and begun testing credit cards on it. Discover consumer card accounts are moving to Capital One's website and app in waves from mid-2026 through 2027, while Discover-branded cards remain on sale. Capital One targets about $2.5 billion of merger synergies by the second half of 2027.
Leadership
Discover's last standalone chief executive was interim CEO J. Michael Shepherd, who served from April 1, 2024 until the deal closed and then joined Capital One's board. Discover is now run within Capital One under founder, chairman and CEO Richard Fairbank.
