In 2025, Wall Street hit a big milestone: For the first time in history, there were more exchange-traded funds to buy than individual stocks. Multiple industry sources suggest the number of U.S. listed ETFs surpassed the number of publicly traded U.S. companies in late August, when they counted roughly 4,300 ETFs and 4,200 listed stocks. Fast-forward to now. The number of ETFs has soared further, reaching 5,072 as of March 31, according to FactSet.
