Final answer:
The oldest corporation in the Americas is Harvard University, founded in 1636, though the question may be mistakenly referring to the New York Stock Exchange, the oldest and largest U.S. stock market established in 1792.
Step-by-step explanation:
The oldest corporation in the Americas, located about four miles northwest of downtown Boston with almost $41 billion in the bank, is Harvard University. Founded in 1636, it predates the concept of a stock market. However, the oldest and largest U.S. stock market is the New York Stock Exchange (NYSE), established in 1792. The NYSE is located at 18 Broad St. in New York City and trades stocks for 2,800 companies. The Boston Manufacturing Company, which started the northeastern textile industry in the early 19th century, is another historical entity headquartering in the region, based in Waltham, Massachusetts. Despite the decline of the Rust Belt, the region from Washington, D.C., to Boston remains the economic heart of North America with numerous corporate headquarters, banks, financial markets such as Wall Street, universities, and cultural institutions.
