Q2 ETF Flows Set Records as U.S. ETF Assets Hit $15T

U.S. exchange-traded fund assets reached $15 trillion in June 2026, and net inflows for the first half of the year exceeded $1 trillion. The second quarter produced the largest quarterly ETF flows on record. Strong demand for AI-related hardware, bond ETFs and new fund launches accounted for much of the activity.

Investors increased exposure during market volatility, allocating to both broad-market and specialized ETFs. Passive index funds accounted for the bulk of dollar volume, while active ETFs made up 80% of new product launches and about 40% of total inflows. Fund providers listed roughly 700 new ETFs by the end of June, including the fastest-growing debut of the year.

Flows clustered around AI infrastructure rather than broad software names. The newly launched Roundhill Memory ETF (DRAM) drew about $17 billion in second-quarter inflows and reached nearly $25 billion in assets. Semiconductor funds as a group recorded about $23 billion in net inflows for the quarter. Managers launched 39 new semiconductor ETFs in 2026, with 36 debuting in the past three months. Investors also added exposure to industrials, energy, utilities and real estate funds tied to data-center supply chains, electrification and cooling systems. The Procure Space ETF (UFO) passed $1 billion in assets in May and changed its index rules to allow immediate exposure to newly listed companies after SpaceX’s IPO.

Large-cap ETFs saw significant growth. Vanguard’s S&P 500 ETF (VOO) posted the largest single-ETF asset increase on record and briefly approached $1 trillion. Midcap funds took in about $12 billion in net flows during the first half, with the iShares Core S&P Mid-Cap ETF (IJH) adding approximately $4 billion. Emerging-market flows slowed from earlier in the year. Regional repositioning included about $3 billion in net outflows from South Korea and roughly $2 billion in inflows each for Avantis’ international and emerging-market equity ETFs (AVDE and AVEM).

Fixed income ETFs passed $2.5 trillion in assets after more than $300 billion of net inflows year to date. Investors moved away from duration risk and into multi-sector and credit-focused strategies. Active bond ETFs captured nearly 40% of bond flows. The Fidelity Total Bond ETF (FBND) and the PIMCO Multisector Bond Active ETF (PYLD) each drew about $2 billion. The JPMorgan Income ETF (JPIE) held roughly 74% of assets in securitized credit and limited government bond exposure. The PGIM AAA CLO ETF (PAAA) crossed $10 billion after nearly $3 billion in quarterly inflows.

Gold ETFs recorded about $3 billion in net outflows as the dollar strengthened, Federal Reserve policy tightened and spot gold fell below $4,000 per ounce. The SPDR Gold MiniShares Trust (GLDM) maintained about $4 billion in year-to-date inflows. Spot Bitcoin ETFs posted roughly $4 billion in net outflows; the iShares Bitcoin Trust (IBIT) shed about $3 billion while some flows moved into yield-focused bitcoin wrappers such as the NEOS Bitcoin High Income ETF (BTCI).

Fund launches and inflow data through June show ETFs continued to be a primary vehicle for institutional allocation decisions in the first half of 2026.
