The U.S. ETF industry is on track for another record year, but beneath the blockbuster inflow numbers, investors are increasingly funneling money into a relatively small group of funds while leaving hundreds of others behind.
U.S.-listed ETFs attracted more than $1 trillion of inflows during the first half of 2026, marking the earliest the industry has ever crossed that milestone. Total ETF assets climbed to a record $15.8 trillion, and State Street Investment Management now projects $2.3 trillion of inflows for the full year, which would easily eclipse 2025’s record.
