June ETF Flows Highlights
- Investors piled $95 billion into exchange-traded funds in June.
- Vanguard S&P 500 ETF VOO and iShares Core S&P 500 ETF IVV traded places: VOO had the most outflows, and IVV had the highest inflows in June.
- International equity ETFs saw their highest monthly inflows ever, beating US equity ETFs for the second consecutive month.
- Year-to-date flows for YieldMax, T. Rowe Price, Morgan Stanley, and BondBloxx ETFs have already surpassed their previous annual records.
- Ultrashort and global bond ETFs collectively pulled in more inflows in the first half of 2025 than their previous yearly inflow records.
The ETF market continued its solid run with $95 billion of net inflows in June. That outranks last month’s $90 billion net flows and June 2024’s $87 billion. Total US ETF flows over the first half of 2025 clocked in at $535 billion.
Most of the fresh capital flowed into passive ETFs; $68.5 billion flowed into index ETFs, $8.4 billion of which went to strategic-beta ETFs. Active ETFs gathered the remaining $25.8 billion.
The table below shows June returns for a sample of Morningstar analyst-rated ETFs that represent major sections of the stock and bond markets.
S&P 500 ETFs: VOO Hit by Outflows, IVV Leads Inflows
June marked the first month of net outflows for VOO since November 2022. It saw $5.6 billion leave the fund, the most of any ETF in June. IVV, on the other hand, saw the most inflows of any ETF. It grabbed $12.6 billion, pulling its year-to-date flows positive after seeing net outflows through May.
VOO, IVV, and State Street’s SPDR S&P 500 ETF Trust SPY are battling for the title of world’s largest ETF by assets. VOO still claims the top spot in June, even with its outflows. However, all three are within arm’s reach of each other.
IShares S&P 100 ETF OEF, which tracks the largest 100 companies in the S&P 500, has blown past previous annual inflows, bringing in $4.8 billion for the year to date through June. OEF pulled in only $3.0 billion in its best full year, 2023. It’s an interesting move, since the US stock market has become more concentrated in a few large names like Nvidia NVDA, Microsoft MSFT, and Apple AAPL. The ETF stows nearly 30% of its holdings in those three names, as of June 2025, making it more top-heavy than the S&P 500 trackers.
Strong International Stock Performance Leads to Record International Equity ETF Flows
International equity ETFs continue to attract strong flows in June, bringing in $24.8 billion. These ETFs surpassed US equity ETFs for the second month in a row, signaling continued investor demand for overseas investment.
International stocks, if investors held them, have cushioned the blow from US stocks’ roller coaster first half. The Morningstar Global Markets ex-US Index, a good proxy for international stocks, rose 17.82% for the year to date through June 2025. It has trounced the Morningstar US Market Index, representing US stocks, which returned 5.99%. Tariffs are a likely culprit for the drive to overseas investment, as uncertainty looms in the US economy.
Investors Seek Safety in Ultrashort Bond ETFs
June flows pushed the ultrashort bond Morningstar Category into record-breaking territory. Its year-to-date flows of $61 billion surpass its annual inflow record of $58.7 billion from 2022. IShares 0-3 Month Treasury Bond ETF SGOV, the largest ETF in the category, drew in $19.9 billion in the first half, over $7.5 billion more than its previous annual record.
ETFs in the global bond category have also surpassed their previous annual record of inflows in the first half of 2025 by pulling in $2.6 billion.
Investors took risk off by pulling money out of ETFs in the trading-leveraged equity category. This is the category’s second consecutive month of heavy outflows.
Several ETF Providers Already Passed Record Yearly Inflows in the First Half
The first half of the year was particularly kind to a handful of ETF providers that have already surpassed their annual flows record, including YieldMax, T. Rowe Price, Morgan Stanley, and BondBloxx.
T. Rowe Price, the largest ETF provider on that list, has brought in $6.6 billion year to date, $1.2 billion more than its previous record annual inflow from 2024. T. Rowe, known for its actively managed mutual funds, is still early in growing its ETF investor base. Its slow start could have resulted from its focus on a semitransparent ETF structure that never caught on with investors. Kudos to T. Rowe for adapting to investor needs by launching only fully transparent ETFs since late 2021, including its largest one, T. Rowe Price Capital Appreciation Equity ETF TCAF, with $4.8 billion in assets.
BondBloxx slices the bond market into precision tools so that investors can be more targeted with their fixed-income ETF allocation. Most assets have found their way into BondBloxx’s target-duration ETFs, but don’t count out BondBloxx Private Credit CLO ETF PCMM: It’s off to a fast start, raising over $100 million in its first six months.
YieldMax offers ETFs that use options to increase cash distributions to investors, including for single stocks. Appearing on our list of worst new ETFs in 2023 and 2024, and a shocking analysis by Morningstar’s Jeffrey Ptak, didn’t stop investors from piling into these ETFs.
