U.S. crypto exchange-traded funds (ETFs) attracted approximately $1.24 billion in net inflows during the week of August 31 to September 4, with bitcoin funds dominating the capital flows. Bitcoin ETFs alone captured $986.85 million, while ether, XRP, solana, and HYPE products also posted positive results for the week.
Bitcoin ETFs Post Third Consecutive Week of Gains
Spot bitcoin ETFs logged $986.85 million in weekly inflows with net assets closing at $101.25 billion. The total represented roughly a 7% increase from $924 million in inflows the previous week.
Thursday proved to be the strongest trading day, with bitcoin ETFs taking in $730.87 million—their third-largest daily inflow of the year and the largest since January 14—as bitcoin's price moved above $80,000. The week included volatility, however. Monday opened with $216.70 million in inflows, followed by a $236.46 million outflow on Tuesday before recovering with $101.15 million on Wednesday and $174.60 million on Friday.
Blackrock's IBIT led individual fund performance with $691.51 million in weekly inflows. Ark & 21Shares' ARKB followed with $137.74 million, while Fidelity's FBTC added $94.88 million. Grayscale's GBTC experienced a $48 million outflow.
Ether, XRP, and Solana See Modest Inflows
Ether ETFs finished the week with $218.41 million in net inflows, extending an inflow streak to 12 consecutive sessions before a midweek pullback. XRP ETFs brought in $18.96 million for the week, while solana ETFs ended with $6.18 million in inflows. HYPE ETFs attracted $12.27 million.
Bitcoin Dominates Capital Allocation
Bitcoin accounted for roughly 79.4% of total inflows across the five ETF categories. Combined, bitcoin and ether represented approximately 97% of total flows, indicating concentrated institutional allocation toward core crypto assets.
Trading activity declined during the period. Bitcoin ETF turnover fell approximately 24% to roughly $14.5 billion, while ether turnover dropped about 35% to $4.09 billion. Combined turnover across all five categories declined around 27% to $19.3 billion.
The pattern reflects a shift toward more concentrated institutional positioning, with capital favoring established assets even as overall trading intensity decreased. Federal Reserve rate expectations emerged as a key factor influencing the market, with stronger U.S. employment data reviving questions about the central bank's rate path late in the week.
