BlackRock’s iShares Bitcoin Trust (IBIT) returned to focus last week after fresh ETF flow data showed strong institutional demand behind Bitcoin’s latest move. According to Arkham, IBIT clients bought about $732.6 million worth of BTC during the week, accounting for most of the $823.7 million in total net inflows into U.S. spot Bitcoin ETFs.
Farside Investors’ data reinforced that trend, showing IBIT posted daily inflows of $256 million, $39.3 million, $246.9 million, $167.5 million, and $22.9 million between April 20 and April 24. That made BlackRock the clear driver of the week’s ETF demand rebound.
US spot Bitcoin ETFs have now locked up roughly 1.32 million BTC — about 6% of the cryptocurrency’s total supply — after a sustained wave of institutional buying that shows no sign of slowing down. April has been a turning point for Bitcoin ETFs. After a difficult start to 2026 marked by heavy redemptions, the products have attracted more than $2.6 billion this month alone — nearly double what came in during March.
The week ending April 24 brought in $823 million in net new capital, the fourth straight week of positive flows. The prior week posted $996 million, while earlier in the month saw $786 million, and a modest $22 million in the first week of April. Together, those figures pushed total Bitcoin ETF assets from $86 billion at the start of the month to $102 billion by April 24, according to data tracked by SoSoValue.
The scale of buying has overwhelmed supply from miners. Over just eight trading days, ETF products absorbed close to 19,000 BTC — well beyond what new mining activity added to circulation during that period. BlackRock’s iShares Bitcoin Trust, known as IBIT, pulled in around $733 million of the week’s total $824 million in inflows, meaning a single product accounted for nearly 90 cents of every dollar that flowed into Bitcoin ETFs during the week.
Bitcoin itself has been trading in a recovery mode. After dipping toward the low $60,000s in February amid broader market uncertainty and earlier ETF outflows, the price climbed back above $78,000. As of Monday morning, BTC was changing hands around $77,810, having briefly touched $79,485 before pulling back. Traders are watching the $79,485 breakout resistance level ahead, with $77K acting as a key support level.
The buying has extended beyond Bitcoin. Spot Ethereum ETFs posted $155 million in inflows for the week, their third consecutive weekly gain. Products tracking Solana and XRP added $9.4 million and $15.7 million, respectively, suggesting broader appetite for regulated digital asset exposure. Not every fund is benefiting — Grayscale’s GBTC continued to see outflows, a sign that capital is flowing unevenly across issuers.
Analysts also point to ongoing risks: potential policy shifts under US President Donald Trump’s administration and signals from the Federal Reserve could still shake investor confidence. For now, though, the numbers tell a story of sustained institutional interest returning to the Bitcoin ETF market after a rocky winter.
