JPMorgan Chase & Co. is an American multinational finance company headquartered in New York City and incorporated in Delaware. It is the largest bank in the United States and the world's largest bank by market capitalization as of 2023. As the largest of Big Four banks, the firm is considered systemically important by the Financial Stability Board. Its size and scale have often led to enhanced regulatory oversight as well as the maintenance of an internal "Fortress Balance Sheet". The firm is headquartered at 383 Madison Avenue in Midtown Manhattan and is set to move into the under-construction JPMorgan Chase Building at 270 Park Avenue in 2025.

383 Madison Avenue, formerly known as the Bear Stearns Building, is a 755 ft (230 m), 47-story skyscraper in the Midtown Manhattan neighborhood of New York City, New York, U.S. Built in 2002 for financial services firm Bear Stearns, it was designed by architect David Childs of Skidmore, Owings & Merrill (SOM). It housed Bear Stearns's world headquarters until 2008, when Bear collapsed and was sold to JPMorgan Chase. Since then, JPMorgan's investment banking division has occupied the building.
