BlackRock's iShares Bitcoin Trust Surpasses 700,000 BTC Holdings

BlackRock has reached a significant milestone in the cryptocurrency market by surpassing 700,000 BTC in holdings through its iShares Bitcoin Trust (IBIT) ETF. This achievement positions IBIT as the largest holder of Bitcoin among all US spot Bitcoin ETFs, controlling approximately 55% of the total Bitcoin held across these funds. The value of IBIT's holdings is estimated to be around $75.5 billion, based on current Bitcoin prices. This substantial holding not only underscores the growing institutional interest in Bitcoin but also highlights the trust and confidence that major financial institutions like BlackRock have in the digital asset.

The surge in IBIT's holdings has also led to a notable increase in its assets under management, which now stand at $76 billion. This figure surpasses the assets under management of major ETFs such as IVV, which tracks the S&P 500, and IWM, which tracks the Russell 2000. The rapid accumulation of Bitcoin by IBIT reflects a broader trend of institutional adoption of cryptocurrencies, as more traditional financial players seek to diversify their portfolios and capitalize on the potential growth of digital assets.

The recent purchase of 1,388 BTC worth $164.3 million by IBIT further demonstrates BlackRock's commitment to expanding its Bitcoin holdings. This acquisition, along with the overall increase in holdings, indicates a strategic move by BlackRock to leverage the potential of Bitcoin as a store of value and a hedge against inflation. The term "digital gold" has been used by BlackRock to describe Bitcoin, emphasizing its role as a long-term investment asset.

This figure is not just symbolic. It reflects a massive change of hands in BTC ownership. Institutions, through ETFs, are devouring the shares of the available supply. Even more, they are accumulating more than what miners create. According to Galaxy Research, US ETFs combined with MicroStrategy have purchased more BTC than mining produced each month in 2025, except in February. With capped issuance and dried-up stocks, bitcoin becomes an increasingly concentrated commodity. And BlackRock establishes itself as a market player impossible to sidestep.

BlackRock’s appetite, coupled with MicroStrategy’s and others’, has created an unprecedented tension. While miners emitted only $7.85 billion in BTC in 2025, institutions purchased $28.22 billion worth. The secondary market is no longer sufficient. But IBIT is not just a vault. Innovation is introduced: the REX-Osprey ETF, recently launched, allows investing in Solana with integrated staking. We are now talking about passive income at the very heart of crypto ETFs. A step toward the tokenization of gains, in the style of traditional finance. This new shift transforms Bitcoin ETFs into tools of yield and accumulation.

Some key figures: 700,307 BTC: under BlackRock’s management; $75.5 billion: approximate value of the asset; +82.67%: IBIT’s return since January; $28.22 billion: BTC purchased by ETFs in 2025; $7.85 billion: BTC created by miners this year. So, long-term strategy or institutional FOMO? In both cases, the rules are changing. Bitcoin is no longer just a store of value: it becomes a yield lever, ETF style.

BlackRock does not limit its ambitions to Bitcoin alone. Larry Fink’s giant now diversifies its crypto portfolio. It , betting on its potential despite uncertainties. In an ecosystem still volatile, it’s a way.
