In 2004, the company acquired Bank One of Chicago, bringing on board Bank One CEO Jamie Dimon as president and COO of the merged firm and designating him as CEO William B. Harrison, Jr.'s future successor. Dimon quickly made his influence felt by embarking on a cost-cutting strategy and placing some former Bank One executives in key ranks at the new company. Dimon became CEO in January 2006, and also became chairman in December 2006.

JPMorgan Chase operates as the brand for the holding company. Chase is used as the brand for credit card services in the United States and Canada and the bank's retail banking activities in the United States.
