BlackRock has sharply increased its crypto ETF selling activity, recording more than $1.21 billion in combined Bitcoin (BTC) and Ethereum (ETH) fund outflows over the past week.
Data on spot crypto ETF flows show that BlackRock’s Bitcoin and Ethereum funds experienced sustained outflows over multiple trading sessions, with Bitcoin accounting for the vast majority of withdrawals.
The development comes as cryptocurrency markets face renewed volatility and profit-taking following earlier gains.
The largest share of the outflows came from BlackRock’s iShares Bitcoin Trust (IBIT), which recorded net withdrawals totaling approximately $1.04 billion over the period.
The heaviest single-day outflow occurred on May 27, when investors pulled $527.8 million from the fund. The selling continued on May 28 with another $177.9 million in withdrawals, followed by $68.2 million on May 29.
Earlier in the week, IBIT also recorded outflows of $192.4 million on May 26 and $68.9 million on May 22, highlighting a persistent trend of institutional capital leaving the Bitcoin ETF.
The scale of the withdrawals mirrors broader weakness across U.S. spot Bitcoin ETFs, which collectively experienced more than $1.52 billion in net outflows during the period.
Ethereum ETF outflows
On the other hand, BlackRock’s spot Ethereum ETF products also registered net outflows, though on a significantly smaller scale than Bitcoin.
The firm’s ETHA fund posted cumulative withdrawals of $193.7 million over the week. The largest daily outflow occurred on May 28, when investors withdrew $80.4 million, followed by $65.1 million on May 27 and $40.7 million on May 29.
Some of the selling pressure was partially offset by inflows into BlackRock’s ETHB fund, which attracted $12.4 million during the period. However, the positive flows were insufficient to offset the broader withdrawals from ETHA.
Combined, BlackRock’s Ethereum ETF products recorded net outflows of approximately $181.3 million.
The outflows suggest institutional investors are reducing crypto exposure, with BlackRock’s Bitcoin and Ethereum ETFs recording a combined $1.22 billion in net withdrawals during the period.
Bitcoin accounted for more than 85% of the outflows, highlighting stronger selling pressure in the asset.
While withdrawals slowed after the May 27 peak, BlackRock’s funds continued to post negative flows, leaving investors focused on whether the recent crypto ETF outflow trend will persist in the coming sessions.
