BlackRock Buys $1 Billion in Bitcoin in Three Days

Key Takeaways

  • BlackRock bought more than $1 billion worth of Bitcoin through its iShares Bitcoin Trust (IBIT) in three trading days.
  • The fund then managed more than 385,000 BTC, equal to about 1.76 percent of the total Bitcoin supply.
  • Inflows through spot Bitcoin ETFs show that institutional demand for regulated Bitcoin exposure is still rising.

BlackRock added more than $1 billion (€0.9 billion) worth of Bitcoin in just three trading days through its iShares Bitcoin Trust (IBIT). After that buying spree, the world’s largest asset manager was overseeing more than 385,000 BTC, or about 1.76 percent of Bitcoin’s total supply, with a value of roughly $26.55 billion (€23.1 billion).

IBIT Keeps Growing Fast

The latest purchase is another sign of how much demand there is for Bitcoin exposure through regulated products. IBIT is designed to give investors direct exposure to Bitcoin, and every time fresh money enters the fund, it buys physical Bitcoin to back the ETF shares. Since launching earlier in 2024, the fund has already pulled in billions of dollars in assets under management, and by March 2026 it had become the largest spot Bitcoin ETF with more than $50 billion (€43.4 billion) in assets under management.

That pace of growth fits a larger trend that started after U.S. spot Bitcoin ETFs were approved in January 2024. For institutions, those products opened a regulated path to Bitcoin exposure without having to hold the asset directly. Market data shows that major issuers such as BlackRock and Fidelity have since accumulated more than $100 billion (€86.8 billion) in combined Bitcoin ETF assets. The latest inflows also line up with the fact that IBIT is drawing capital again after a weaker stretch earlier on.

What This Says About the Market

For the crypto market, the bigger takeaway is that this kind of buying can tighten the amount of Bitcoin available for trading. If large investors continue to gain exposure through ETFs, less of the supply ends up circulating back into the market. That makes spot ETFs more than just a way to invest, they have also become a major route for institutional capital.

Still, the flow of money is not always one-way. Strong inflows can be followed by outflows when macro conditions shift or investors rotate into other assets. So BlackRock’s latest buying is best seen as another sign that institutional Bitcoin adoption through ETFs is still advancing, not as proof that inflows will stay steady without interruption.

Why European Readers Should Care

For European crypto investors, the key point is that the U.S. ETF market is increasingly shaping how major asset managers think about Bitcoin. The combination of regulated access, heavy inflows, and a growing product lineup could also influence how European firms build and distribute their own crypto offerings. For platforms like Finst, it mainly underscores how important transparent, regulated access to crypto has become in a market that is getting more institutional every day.
