NYSE Group, Inc.

The NYSE Group, Inc. is an American company that evolved from the New York Stock Exchange (NYSE), one of the world's largest marketplaces for securities and investments. The NYSE originated from a meeting of stockbrokers in 1792 on Wall Street, New York City, and was formally established as the New York Stock and Exchange Board in 1817.1

The exchange played a crucial role in providing capital for the industrialization of the United States, especially after the Civil War. Following the stock market crash of 1929, the NYSE became subject to federal regulation by the Securities and Exchange Commission (SEC). In 2006, the NYSE merged with Archipelago Holdings to form the publicly held NYSE Group, Inc.. This entity later merged with Euronext N.V. to create NYSE Euronext, which subsequently acquired the American Stock Exchange. In 2012, NYSE Euronext was acquired by Intercontinental Exchange.1
