What company resulted from the 2004 merger of Bank One and JPMorgan Chase?

The 2004 merger of Bank One and JPMorgan Chase resulted in JPMorgan Chase.

JPMorgan Chase announced its agreement to acquire Bank One in 2004, and the transaction was completed later that year. The combined company retained the JPMorgan Chase name and became one of the largest banking organizations in the United States.

Bank One had a strong retail-banking presence, especially in the Midwest, while JPMorgan Chase brought major investment banking, corporate banking and consumer-finance operations. Jamie Dimon, then Bank One’s chief executive, became president and chief operating officer of the combined company and later became chief executive.

This deal is sometimes confused with JPMorgan’s 2000 merger with Chase Manhattan, which created JPMorgan Chase & Co. The 2004 transaction specifically joined that company with Bank One. JPMorgan Chase later acquired Bear Stearns and Washington Mutual’s banking operations during the 2008 financial crisis.
