BlackRock’s iShares Bitcoin Trust (IBIT), currently the world’s largest spot Bitcoin ETF, expanded its massive treasury recently by acquiring an additional 3,352 BTC. This strategic move, highlighted by ETF tracker Thomas Fahrer, pushes the fund’s total reserves to 806,000 BTC, valued at over $61 billion based on a market price of approximately $76,000 per Bitcoin.

U.S. Bitcoin spot ETFs record $238 million net inflow as total assets top $102 billion
U.S. spot Bitcoin ETFs saw a strong wave of fresh money on April 20, pulling in about $238 million in net inflows for the day. BlackRock’s iShares Bitcoin Trust (IBIT) led the pack once again, bringing in roughly 3,230 BTC and continuing its streak as the top destination for new capital.
Other funds also saw smaller inflows. The Valkyrie Bitcoin Fund (BRRR) added about 78.6 BTC, while Galaxy Digital’s MSBT brought in around 109.8 BTC. Not every fund shared in the gains, though. Grayscale’s GBTC continued to see money leave, with about 337.6 BTC in outflows, while Fidelity’s FBTC recorded a smaller dip of around 89.5 BTC.
Zooming out, the bigger picture shows how much these products have grown. Since launch, U.S. spot Bitcoin ETFs have pulled in over $58 billion in net inflows, with total assets now sitting just above $102 billion and daily trading activity around $3.3 billion. It’s a clear sign that Bitcoin exposure is no longer just a retail story as more institutions are finding their way in through these regulated products.
Institutional demand is increasingly funnelling through IBIT
BlackRock isn’t the only one buying, but it’s quickly becoming the place where most institutional money is going. Since spot Bitcoin ETFs were approved in the U.S. in early 2024, IBIT has pulled in more consistent inflows than any other fund, making it a go-to option for investors who want Bitcoin exposure without dealing with the technical side of crypto.
That appeal is simple. With IBIT, institutions don’t have to worry about private keys, custody setups, or interacting with blockchain networks. They can get exposure to Bitcoin the same way they would buy a stock or ETF, which fits much more easily into how they already manage money. For pension funds, asset managers, and corporate treasuries, that familiarity matters.
At this scale, the impact goes beyond just one fund. When money consistently flows through ETFs like IBIT, it starts to shape how the market behaves, affecting liquidity, smoothing volatility, and increasingly influencing short-term price moves.

Bitcoin’s Institutional Ownership Is Still Evolving
The introduction of spot ETFs changed the way many investors access Bitcoin, while developments in custody, derivatives and in-kind ETF mechanisms have continued to reduce some of the structural barriers between crypto markets and traditional finance.
BlackRock’s latest move to reduce the in-kind conversion threshold suggests that the ETF ecosystem is still evolving more than two years after its launch. For Bitcoin, the key question is how much of the market’s future demand will flow through regulated investment products such as IBIT, and whether that demand remains resilient during periods of weaker Bitcoin prices.
With IBIT continuing to rank among the largest Bitcoin investment vehicles, its holdings and daily flows are likely to remain closely watched indicators of institutional participation in the market.
