U.S.-listed exchange-traded funds are drawing capital at a record pace, with net inflows reaching approximately $1.93 trillion through September 29, according to data compiled by Citadel Securities. This total represents a $580 billion increase, or 43% growth, compared to the same period in 2025.
The third quarter delivered the strongest quarterly performance on record, attracting $771 billion in inflows and establishing a new benchmark for ETF flows. At this pace, annual inflows are tracking toward exceeding $2.5 trillion if the momentum continues.
Broad-Based Demand Across Asset Classes
The surge reflects strong demand spanning multiple investment categories rather than concentration in a single segment. State Street Investment Management separately estimated more than $1.54 trillion in U.S.-listed ETF inflows through September, already surpassing its $1.52 trillion full-year record from 2025. The firm projected flows near $2.3 trillion by year-end.
Equity ETFs led the category with more than $1 trillion in inflows, while fixed-income products attracted over $469 billion. Within equities, funds tracking U.S. stocks received approximately $655 billion, and technology sector ETFs added more than $59 billion.
Growth of Index-Linked Products
The expanding inflows contributed to broader industry asset growth. According to Investment Company Institute data, U.S. ETF assets reached $16.27 trillion in August, while indexed mutual funds held $22.4 trillion. Combined, indexed mutual funds and ETFs represented 54.3% of all long-term fund assets, indicating that index-linked products now account for more than half of that market.
Crypto ETF Participation
Cryptocurrency ETFs also participated in the shift toward regulated fund wrappers, though their flows remained substantially smaller than traditional ETF totals. U.S. spot Bitcoin ETFs attracted approximately $2.65 billion in September, while spot Ether ETFs received roughly $832 million during the same month, according to SoSoValue data.
