How many publicly traded companies in us over last 5 years?

As of 2023, there are approximately 4,000 publicly traded companies listed on major U.S. stock exchanges, such as the NYSE and NASDAQ. Over the last five years, the number of publicly traded companies has fluctuated due to factors like IPOs, mergers, and delistings. In recent years, a notable increase in IPOs, particularly in the tech sector, has contributed to this dynamic. However, the overall trend can vary year by year based on market conditions and investor sentiment.
