Capital One is an American bank founded in 1994 that began as a credit card monoline built on statistical testing of offers and pricing, an approach it called information-based strategy. It is now one of the largest card issuers in the United States alongside a national direct bank, an auto lending business and a commercial bank, and it completed the acquisition of Discover in 2025, which gave it a payments network of its own rather than dependence on Visa and Mastercard. Headquartered in McLean, Virginia, it was also an early mover among large banks in migrating its entire technology estate to the public cloud.
