American Bitcoin exchange-traded funds have returned to capital inflows. On Monday, August 31, ETFs attracted $216.7 million. This volume fully offset Friday's outflow of $201.8 million. Nearly all of the inflow was provided by a single issuer, BlackRock. The outflow on August 28 interrupted a nine-session winning streak. Over that period, the funds received more than $3 billion. Meanwhile, Ethereum ETFs extended their inflow streak to 11 sessions. XRP and Solana funds recorded their tenth consecutive session with a positive balance.
BlackRock's iShares Bitcoin Trust led the inflow recovery. The product attracted $205.9 million in a single day, accounting for approximately 95% of the entire day's category volume. Other issuers added capital on a significantly smaller scale. Fidelity's Wise Origin Bitcoin Fund received $6.9 million. The Bitwise Bitcoin ETF attracted $4.3 million. Grayscale's Bitcoin Mini Trust received $9.4 million. Morgan Stanley's Bitcoin Trust added $3.6 million. The only fund to record an outflow was VanEck's Bitcoin ETF, which lost $13.4 million.
Ethereum ETFs attracted $87.7 million on Monday, marking the eleventh consecutive session with capital inflows. BlackRock's iShares Ethereum Trust again led the way, receiving $59.9 million. Grayscale's Ethereum Mini Trust followed with $13.5 million. Fidelity's Ethereum Fund attracted $9.3 million. XRP funds extended their positive streak to ten sessions, with the category attracting $5.64 million. Capital has been flowing in every trading session since August 18.
Solana funds also recorded their tenth consecutive session with a positive balance, though the pace of inflows slowed noticeably. The category attracted just $925,000, compared to $18.1 million on Friday — the weakest daily figure in the current streak. Large institutional players continue to account for the bulk of demand. BlackRock remains the key driver of momentum in the Bitcoin and Ethereum segments.
The dominance of a single issuer raises questions about structural market concentration. BlackRock has already accumulated more than 3% of the entire Bitcoin supply. The private keys to these assets are held by Coinbase Custody. The gold ETF SPDR Gold Shares took more than 1,600 trading days to reach $70 billion in assets. The IBIT fund covered the same ground in less than a year. Such a rapid pace of accumulation makes the market dependent on the infrastructure decisions of a single custodian — a concentration risk that is rarely discussed publicly within the professional community.
