Blackrock Increases Ibit Bitcoin ETF Exposure By 25%

BlackRock has quietly sold its shares in the Bitcoin Exchange-traded fund (ETF) expands, underscoring this asset manager’s growing commitment to cryptocurrency as part of a broader diversification strategy.

As of March 31, 2025, the BlackRock Strategic Income Opportunities Portfolio owned 2.123.592 shares of iShares Bitcoin Trust (IBIT), valued at $99,4 million, according to U.S. Securities and Exchange Commission (SEC) filings. This is a significant increase from December 31, 2024, when the Portfolio held 1.691.143 IBIT shares.

BlackRock’s IBIT was one of eleven spot Bitcoin ETFs approved by the SEC in January 2024. It has since grown to become the largest fund in its category, with over $72 billion in net assets, as reported by Bitbo.

The second largest Bitcoin ETF in the US is the Fidelity Wise Origin Fund (FBTC), which trails IBIT by $50 billion in terms of net assets.

The Strategic Income Opportunities Portfolio focuses primarily on bonds, but also seeks to gain diversified exposure to other markets, with the goal of enhancing total returns while preserving capital, according to BlackRock's prospectus.

Demand for Bitcoin ETF continues to rise among institutional investors

Spot Bitcoin ETFs in the US have broken records in their debut year, and 2025 looks set to be promising as well.

According to Cointelegraph, May could be a record month for spot ETFs, which saw over $1,5 billion in net impact in just two days.

BlackRock's IBIT has driven much of this growth, with consistent inflows since April 9, recording multiple days of net purchases in excess of $500 million.

Net impact indicates that asset managers are buying shares of Bitcoin ETFs to meet growing investor demand.

Using the early successes of gold ETFs as a benchmark, asset manager Bitwise recently predicted that flows into Bitcoin funds could reach $120 billion this year and more than double to $300 billion by 2026.

While spot Bitcoin ETFs have opened the door to retail and institutional investors, there remains a significant untapped market segment: the asset management platforms and wirehouses of large institutions, Bitwise analysts Juan Leon, Guillaume Girard and Will Owens said in their report.

Closing note

The growing confidence and demand for Bitcoin ETFs signals a fundamental shift in the adoption of cryptocurrency by institutional investors. As the market continues to evolve, it is critical for investors to stay informed about the opportunities and challenges that present themselves within this dynamic sector.
