About The Oldest Stock Exchange In America
Founded in 1790 and originally named the Board of Brokers of Philadelphia
A stock exchange (also called a securities exchange or bourse) is an organized marketplace where buyers and sellers (typically through stockbrokers and traders) can buy and sell securities. These include stocks (shares of ownership in companies), bonds, exchange-traded funds (ETFs), and other financial instruments.
The Philadelphia Stock Exchange (PHLX) is the first stock exchange established in the United States. It was founded in 1790 and originally named the Board of Brokers of Philadelphia. It is the nation's oldest, founded two years before the New York Stock Exchange, and third-oldest globally, after the Amsterdam Exchange (founded 1602) and the Paris Bourse (1724).
The Library of Congress recognizes it as the oldest stock exchange in America. The Encyclopedia of Greater Philadelphia describes it as the nation’s oldest exchange. The U.S. Department of State defines it as the first U.S. stock exchange.
Early investors were betting on more than just individual companies — they were betting on the success of the United States itself. Many of the securities traded were related to federal debt and government bonds, part of Alexander Hamilton's plan to stabilize national credit.
The Philadelphia Stock Exchange raised money to fund public works around Philadelphia and also provided financial capital for many early American businesses, including The First Bank of the United States.
This exchange raised money for necessary public works projects, including the Philadelphia and Lancaster Turnpike Company, America's first turnpike. The exchange also handled bank and insurance stocks, permitting firms to acquire needed financial capital.
In 1875, the Board of Brokers changed its name to the Philadelphia Stock Exchange. In 1949, the exchange merged with the Baltimore Stock Exchange. In 1954, it merged with the Washington Stock Exchange, and in 1969, it acquired the Pittsburgh Stock Exchange.
When the War of 1812 disrupted American trade, the exchange helped the federal government raise capital for defense. However, financial problems eventually erupted — total debt for American infrastructure soared, yielding bond defaults and capital flight to Europe. The American economy collapsed in 1837. Only in the 1840s did the growth of railways spur the exchange's recovery.
On November 7, 2007, NASDAQ announced an agreement to purchase PHLX for $652 million, with the acquisition completing on July 24, 2008, creating the third-largest options market in the U.S. Today it operates as Nasdaq PHLX, focused primarily on options trading.
While the PHLX is the oldest, the NYSE became far larger and more influential. New York wasn't the center of finance in North America when trading began — that distinction belonged to Philadelphia. But after the Erie Canal started carrying trade to New York City from Ohio and the West, Manhattan eclipsed Philadelphia as the financial center of North America.
In short, Philadelphia quietly laid the foundation for American capitalism, even if New York eventually stole the spotlight. Today, the Philadelphia Stock Exchange may no longer command the global prestige it once held, but its legacy is undeniable. From financing the young republic's debts to funding the nation's first turnpike, it was the cradle of American capitalism.
It survived wars, financial panics, and the rise of New York, outlasting rival exchanges through mergers and reinvention across more than two centuries. For a nation that often looks to Wall Street as the symbol of its financial identity, it's a quiet but powerful reminder that the real story began not in Manhattan, but in Philadelphia.
