BlackRock accumulated nearly $1 billion worth of cryptocurrencies over the past trading week, driven primarily by strong inflows into its Bitcoin (BTC) and Ethereum (ETH) spot exchange-traded funds (ETFs).
The bulk of the buying came through BlackRock’s iShares Bitcoin Trust, which recorded about $732.6 million in net inflows over five sessions.
Demand was particularly strong midweek, with April 22 and April 20 standing out as the largest accumulation days, drawing roughly $246.9 million and $256 million, respectively.
Momentum remained firm on April 23 with another $167.5 million added, although inflows cooled toward the end of the period, with April 24 posting a more modest $22.9 million.
Despite some minor outflows in competing funds, the overall trend reflected sustained institutional appetite for Bitcoin exposure.
BlackRock Ethereum inflows
Ethereum also saw consistent, albeit smaller, allocations. To this end, BlackRock’s Ethereum ETFs collectively attracted about $199 million in net inflows over the same period.
The strongest day came on April 20, when combined inflows reached approximately $89.3 million, followed by another solid performance on April 21 with $52.5 million added.
April 22 extended the positive trend with $53.6 million in inflows. However, the sequence was interrupted on April 23, when the funds recorded a net outflow of about $21 million, before rebounding on April 24 with a net gain of $24.6 million.
In total, the world’s largest asset investment manager bought roughly $931.6 million worth of cryptocurrencies during the week.
Overall, as the crypto market recovered, institutional investors continued to pour sustained capital into U.S. spot cryptocurrency ETFs this month.
Bitcoin funds have recorded their strongest performance of 2026, while Ethereum products have posted extended inflow streaks.
Spot Bitcoin ETFs logged an eight-day consecutive inflow streak through April 23, attracting approximately $2.1 billion in net new capital.
The surge pushed April inflows to around $2.4 billion, nearly double March’s total, and returned year-to-date flows to positive territory.
