ETF flows in 2026 are running at a record pace. Net issuance of U.S. exchange-traded fund shares reached $1.18 trillion in the first seven months of 2026, against $655.9 billion in the same period of 2025, according to the Investment Company Institute (ICI) [1]. July alone added $188.93 billion, even as total ETF assets slipped 0.2% to $15.67 trillion because of price declines, after rising $100.81 billion in June to $15.70 trillion [1][2]. Weekly data through September 2 show the inflows continuing, with taxable bond ETFs the most consistent destination [3].

Data: ICI Exchange-Traded Fund Data, July 2026 [1].
Domestic equity ETFs held $10,090.4 billion, about 64% of all ETF assets, and accounted for $2.40 trillion of the $3.92 trillion (33.3%) increase in total assets over the twelve months to July [1]. The product count keeps growing as well: 5,182 ETFs in July 2026, up from 5,060 in June, including 2,967 domestic equity funds, 975 global and international equity funds, 978 bond funds, 137 commodity funds and 125 hybrid funds [1][2].
ETF flows in 2026: where the money went week by week
| Week ended | Domestic equity | World equity | Taxable bond | Municipal bond | Commodity | Total ETF net issuance |
|---|---|---|---|---|---|---|
| Aug 19, 2026 | $27,491M | $6,725M | $12,811M | $974M | $1,835M | $49,970M |
| Aug 26, 2026 | $7,624M | $6,864M | $12,054M | $1,729M | $3,394M | $32,089M |
| Sep 2, 2026 | $12,393M | $5,809M | $11,567M | $705M | $2,573M | $33,240M |
Data: ICI weekly estimated ETF net issuance; the small hybrid category is omitted [3].
Three patterns stand out. Taxable bond ETFs took in $11.6 billion to $12.8 billion every week, the steadiest category by far [3]. Domestic equity flows were larger but lumpier, ranging from $7.6 billion to $27.5 billion [3]. Commodity ETFs, a category dominated by gold funds, drew $1.8 billion to $3.4 billion a week in late August as gold rallied, a meaningful sum for a category with $315.4 billion in assets [1][3]. World equity ETFs also took in $5.8 billion to $6.9 billion a week, consistent with the stronger returns of international funds in 2026 [3].
Assets versus flows: June and July 2026
Net issuance and asset growth are different things. Net issuance counts new ETF shares created minus shares redeemed; asset growth adds market performance on top. In June 2026 total ETF assets rose $100.81 billion, or 0.6%, to $15.70 trillion, a month in which the fund count reached 5,060 [2]. In July net issuance of $188.93 billion was more than offset by falling prices, so assets ended the month $31.03 billion lower at $15.67 trillion [1]. Over the twelve months to July, by contrast, assets grew $3.92 trillion from $11.76 trillion, and domestic equity ETFs alone accounted for $2.40 trillion of that increase, a combination of strong stock returns and heavy inflows [1]. Investors reading flow headlines should keep the two apart: a record month of inflows can coincide with a loss, and a quiet month for flows can coincide with a large gain.
The rotation out of mutual funds
ICI's combined data for long-term mutual funds and ETFs show the other side of the ledger. In the week ended August 26, 2026, domestic equity mutual funds and ETFs together had net outflows of $18.06 billion even though domestic equity ETFs alone took in $7.62 billion, which implies roughly $25.7 billion left domestic equity mutual funds that week [3][4]. In the week ended September 2 the combined domestic equity figure was minus $4.72 billion against an ETF inflow of $12.39 billion [3][4]. Money is not so much entering the stock market through ETFs as moving into ETFs from older fund structures, a shift driven by lower fees, intraday trading and tax efficiency.
What the flow data mean for investors
- Flows are not forecasts: July's $188.93 billion of net issuance coincided with a $31.03 billion fall in assets, so record buying did not prevent a down month [1].
- Bond ETFs are the growth story: with $2,568.3 billion in assets and steady weekly inflows, fixed income is where ETF adoption still has the most room [1][3].
- Concentration in the core: broad-based domestic equity funds, dominated by S&P 500 trackers, held $8,869.1 billion, more than half of all ETF assets [1].
- Product proliferation: 122 net new ETFs in a single month means more choice and, eventually, more closures; investors may consider sticking with large, low-cost funds [1][2].
Investors added $1.18 trillion to ETFs in the first seven months of 2026, almost twice the 2025 pace, with bond funds the steadiest buyers and much of the equity money migrating from mutual funds.
