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.
A Month Of Mounting CapitalApril 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.
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.
One fund has driven much of the momentum. BlackRock’s iShares Bitcoin Trust, known as IBIT, pulled in around $733 million of the week’s total $824 million in inflows. That means a single product accounted for nearly 90 cents of every dollar that flowed into Bitcoin ETFs during the week.
IBIT’s dominance helped push the broader market past the $100 billion mark in total assets under management.
As of Monday morning, BTC was changing hands around $77,810, having briefly touched $79,40 before pulling back. That is still a long way from its all-time high of approximately $126,195, reached in November 2025.
Other Crypto ETFs Join The RallyNot every fund is benefiting. Grayscale’s GBTC continued to see outflows, a sign that capital is flowing unevenly across issuers.
For now, though, the numbers tell a story of sustained institutional interest returning to the Bitcoin ETF market after a rocky winter.
