The New York Stock Exchange is formed under the Buttonwood Agreement.

The New York Stock Exchange is an American stock exchange in the Financial District of Lower Manhattan in New York City. It is the largest stock exchange in the world by market capitalization, exceeding $25 trillion in July 2024. The NYSE is owned by Intercontinental Exchange, an American holding company that it also lists. Previously, it was part of NYSE Euronext (NYX), which was formed by the NYSE's 2007 merger with Euronext. According to a Gallup poll conducted in 2022, approximately 58% of American adults reported having money invested in the stock market, either through individual stocks, mutual funds, or retirement accounts.

The Buttonwood Agreement is the founding document of what is now the New York Stock Exchange and is one of the most important financial documents in U.S. history. The agreement organized securities trading in New York City and was signed on May 17, 1792 between 24 stockbrokers outside of 68 Wall Street. According to legend the signing took place under a buttonwood tree where their earliest transactions had occurred. The New York Stock Exchange celebrates the signing of this agreement on May 17, 1792 as its founding.
