ETF Investors Add $38B as Stocks Hit Records, Crypto ETFs Surge
Last week’s strong weekly inflows brought the year-to-date haul up to $730 billion.
U.S.-listed ETFs pulled in nearly $38 billion during the week ending Friday, Aug. 15, as both the S&P 500 and Nasdaq-100 climbed to fresh all-time highs. Year-to-date inflows now stand at almost $730 billion, keeping 2025 on pace to be one of the strongest years ever for ETF demand.
Equity & Bond Strength
U.S. equity ETFs absorbed $13.3 billion, while international equity ETFs took in $8.8 billion. On the fixed income side, investors added $10.7 billion to U.S. bond ETFs. Currency ETFs also saw meaningful demand, with $4.5 billion of inflows.
The Invesco QQQ Trust (QQQ) led all ETFs with $6.7 billion in inflows, followed by the Vanguard S&P 500 ETF (VOO) with $3 billion. Both ETFs hit records, bringing their year-to-date gains to more than 13% and 10%, respectively.
A surprise entry in the top three was the ARK Innovation ETF (ARKK), which attracted $2.7 billion of weekly inflows. While eye-catching, ARKK’s flows have been volatile, with some large inflows quickly reversing into outflows, raising the question of whether last week’s surge will stick.
Crypto ETFs Dominate
One place where inflows are clearly sticking is in crypto. The iShares Ethereum Trust ETF (ETHA) brought in $2.2 billion as ether prices briefly topped $4,700—within striking distance of the 2021 peak of $4,800.
Prices have since pulled back about 10%, but still, ETHA’s year-to-date haul now totals a robust $8.6 billion.
Meanwhile, the iShares Bitcoin Trust ETF (IBIT) added $1.1 billion, lifting its 2025 inflows to a remarkable $21.4 billion. Bitcoin prices set a new record of $123,000 before easing by around 5%.
Other Weekly Winners & Losers
Beyond the leaders, notable inflows went to the Vanguard Intermediate-Term Corporate Bond ETF (VCIT), the iShares Expanded Tech Sector ETF (IGM), and the iShares Russell 2000 ETF (IWM).
On the outflows side, the Communication Services Select Sector SPDR Fund (XLC)—which is dominated by Alphabet and Meta—led with $3.4 billion in redemptions.
The SPDR S&P 500 ETF Trust (SPY) shed $2.4 billion, while the leveraged Direxion Daily Semiconductor Bull 3X Shares (SOXL) lost $1.5 billion amid profit taking and a late-week semiconductor selloff sparked by Applied Materials’ earnings.
