Bitcoin Captures Nearly 80% of U.S. Crypto ETF Inflows as Funds Add $1.24 B

U.S. crypto exchange‑traded funds (ETFs) saw net inflows of roughly $1.24 billion during the week of Aug. 31 to Sept. 4, driven overwhelmingly by Bitcoin products.

Bitcoin ETFs dominate inflows

Spot Bitcoin ETFs recorded $986.85 million in net inflows, representing 79.4% of total weekly inflows across the five tracked ETF categories. Net assets of Bitcoin ETFs rose to $101.25 billion, up about 7% from the previous week.

Daily activity peaked on Thursday with $730.87 million entering Bitcoin ETFs – the third‑largest daily inflow of 2026 and the biggest since Jan. 14 – as Bitcoin’s price moved above $80,000.

Top Bitcoin ETF contributors

• BlackRock’s IBIT: $691.51 million
• ARK & 21Shares’ ARKB: $137.74 million
• Fidelity’s FBTC: $94.88 million
• Grayscale’s GBTC: outflow of $48 million

Other crypto ETFs see modest gains

Ether ETFs added $218.41 million in net inflows, extending a 12‑session inflow streak before a brief outflow on Wednesday. The category recovered with $141.39 million on Thursday and $26.46 million on Friday.

XRP ETFs posted a weekly net inflow of $18.96 million, while Solana ETFs recorded $6.18 million. HYPE‑related ETFs attracted $12.27 million, driven largely by a $10.52 million inflow on Friday.

Concentration and trading activity

Combined, Bitcoin and Ether accounted for about 97% of total inflows, up from roughly 84.5% the prior week. Trading turnover declined across the board: Bitcoin ETF turnover fell about 24% to $14.5 billion, Ether ETF turnover dropped about 35% to $4.09 billion, and total turnover across the five categories slipped roughly 27% to $19.3 billion.

Outlook

Analysts note that stronger U.S. employment data and expectations of higher Federal Reserve rates could test whether Bitcoin ETF inflows remain elevated amid a potentially risk‑averse environment.
