U.S.-listed ETFs concluded the month of May with $15.7 trillion in total assets under management. This represents a modest 6.3% increase above the $14.7 trillion posted at the end of April. Monthly fund flows accelerated in May, with inflows of $199.4 billion. U.S. ETFs have taken in $843.2 billion over the first five months of 2026.
Investors eased up from putting new money toward equities. While equities attracted 65.3% of May fund flows, or $130.2 billion in assets, this is down from 77.5% of net new assets that were added during April. Interest in fixed income ETFs rose in May, attracting 30% of the monthly inflows, or $60.3 billion, up from 18% of April’s fund flows. Net inflows to other asset classes such as alternatives, asset allocation, and commodity ETFs were reduced to $8.8 billion by currency ETF outflows of $781.7 million.
May saw a significant jump in the number of new ETFs, with 148 ETFs launching. This jump was largely due to 37 ETFs Corgi Insurance Services launched.
