Which company became the first U.S. bank to exceed a $500 billion market capitalization?

JPMorgan Chase became the first U.S. bank to exceed a $500 billion market capitalization in 2024.

The milestone reflected JPMorgan Chase’s position as the largest U.S. bank by assets and its strong earnings during a period of higher interest rates. Investors also valued its diversified businesses, including consumer banking, credit cards, commercial banking, investment banking, asset management, and trading.

Market capitalization measures the value investors assign to a bank’s common equity. It is different from total assets, which include loans, securities, and other balance-sheet items. A bank can therefore rank very high by assets while having a different ranking by market value.

JPMorgan Chase was created through the 2000 merger of J.P. Morgan and Chase Manhattan. Its modern scale also reflects earlier acquisitions, including Bank One and Washington Mutual’s banking operations. The company is not the same entity as JPMorgan, Chase, or Bank One considered separately in earlier periods.
