IBIT fund reaches 771,000 BTC by end of 2025, solidifying BlackRock’s dominance

BlackRock, the world’s largest asset manager, had a huge institutional position in Bitcoin at the end of 2025, with approximately 771,000 Bitcoins held in its direct iShares Bitcoin Trust (IBIT) trading fund as of December 31, 2025, a move that reflects the consolidation of its digital asset strategy.

According to information released by the fund, IBIT held approximately $67.49 billion worth of Bitcoin at the end of the year, equivalent to 100% of its portfolio investment weight, in addition to allocating approximately $38,894 of limited cash for operating purposes.

The total holdings reached approximately 770,791.55 Bitcoins, confirming the fund’s status as the world’s largest spot Bitcoin ETF and one of the most liquid funds among Bitcoin-related trading products in terms of activity and market depth.

This growth has been achieved despite a relatively difficult price environment for Bitcoin in 2025, demonstrating that adoption momentum is not driven by short-term performance but is based on the provision of regulated and accessible investment structures and growing institutional demand.

Market observers and BlackRock officials describe the IBIT fund as one of the most successful ETFs launched in history, and it has also become one of the company’s most profitable products, exceeding the returns of a large number of established traditional funds.
