Fortune 500 companies, the biggest firms in the U.S. by revenue, play a significant role in the U.S. economy. They comprise two-thirds of U.S. GDP — a combined $18.8 trillion in revenues and $43 trillion in market value (as of March 28). They also employ about 31 million people around the globe, according to Fortune.
