Bitcoin ETF Volume Hits $22B as Assets Rise 25%
The week opened with a rebound and ended with a rush.
Bitcoin exchange-traded funds (ETFs) attracted fresh capital in every session, building from a $297.56 million Monday inflow to a three-day burst that carried the category to its strongest weekly result in months. Ether followed the same path, while XRP and solana funds quietly built momentum all week.
Bitcoin Leads a Five-Day Buying Run
Bitcoin ETFs recorded $1.92 billion in net inflows for the week.
Monday brought $297.56 million, followed by $189.30 million on Tuesday. Demand accelerated on Wednesday as bitcoin moved above $70,000, sending $517.19 million into the funds. Thursday delivered the biggest session at $606.29 million, while Friday added another $307.45 million.
Blackrock’s IBIT dominated the weekly ledger with $1.33 billion in inflows. Fidelity’s FBTC added $293.1 million, while ARK 21Shares’ ARKB brought in $126.9 million.
Bitwise’s BITB gained $87.3 million. Morgan Stanley’s MSBT added $28.9 million, Grayscale’s GBTC attracted $21.2 million, and the Bitcoin Mini Trust brought in $36.2 million. Vaneck’s HODL was the main exception, losing $16.1 million.
Bitcoin ETF trading volume reached $22.1 billion for the week, more than triple the prior week’s $6.9 billion. Assets under management rose to $96.07 billion, up 25%. Nearly $1 billion flowed into bitcoin ETFs over the final three sessions alone, the strongest three-day run since Bitcoin last traded above $80,000.
Ether and Altcoins Join the Gains
Ether ETFs also finished every session in positive territory, collecting $697 million for the week.
Inflows rose from $30.85 million on Monday to $71.47 million on Tuesday, then accelerated to $189.15 million on Wednesday and $220.77 million on Thursday. Friday closed with another $184.93 million.
Combined bitcoin and ether ETF inflows reached $2.62 billion, the largest weekly total since October 2025.
XRP ETFs attracted $39.78 million, helped by strong Thursday and Friday inflows of $13.24 million and $18.38 million.
Solana funds added $28.34 million, with most of the demand arriving late in the week. HYPE ETFs finished with $3.89 million in net inflows. A $1.97 million Wednesday outflow was more than offset by Thursday’s $5.86 million addition.
Sosovalue highlighted the difference in flow intensity between the two largest crypto assets. Bitcoin’s $1.92 billion weekly inflow represented about 2.0% of its $96.07 billion in assets, while Ether’s $697 million inflow equaled roughly 4.9% of its $14.29 billion asset base.
“ETH continued to absorb significantly more capital relative to its existing ETF size,” Sosovalue noted. That stronger proportional demand helped amplify Ether’s move from around $1,900 to as high as $2,546, with ETF buying, corporate treasury exposure and staking-related supply constraints all contributing to tighter supply-demand dynamics.
