Close to $2 trillion — that's what the U.S. exchange-traded fund (ETF) industry is poised to collect this year in net inflows (new money in, minus the money that goes out), a sum roughly the size of Spain's economy.
Over the first five months of 2026, ETFs, which invest in pooled baskets of securities but trade like individual stocks, pulled in $771 billion. "ETF market share continues to grow, for sure," says Todd Rosenbluth, head of research and editorial at TMX VettaFi.
