VOO and Core U.S. ETFs Lead 2026 ETF Inflows

Investors poured billions into exchange-traded funds through the second quarter of 2026, led by the Vanguard S&P 500 ETF (VOO), which recorded $75.69 billion in inflows.

VOO surpassed $1 trillion in assets under management during the period. The State Street SPDR Portfolio S&P 500 ETF (SPYM) took in $36.53 billion, the Vanguard Total Stock Market ETF (VTI) added $27.27 billion and the Invesco NASDAQ 100 ETF (QQQM) attracted $12.39 billion.

Interest in non-U.S. markets increased. The Vanguard Total International Stock ETF (VXUS) gathered $15.63 billion and the iShares Core MSCI Emerging Markets ETF (IEMG) received $10.79 billion. Market participants cited concern about concentrated returns among a small number of U.S. megacap technology firms and sought broader geographic exposure and lower relative valuations.

Thematic funds tied to artificial intelligence drew large inflows focused on hardware and memory. The Roundhill Memory ETF (DRAM), launched in April 2026, has taken in about $12.73 billion since its debut, targeting memory semiconductors used in AI computing and data storage.

Fixed-income ETFs also saw substantial net flows. The iShares 0-3 Month Treasury Bond ETF (SGOV) recorded $25.01 billion as investors used short-term Treasuries for cash management. The Vanguard Total Bond Market ETF (BND) added roughly $13.1 billion for broad investment-grade exposure. Dividend-focused equity funds attracted cash as well, with the Schwab US Dividend Equity ETF (SCHD) collecting $10.59 billion.
