BlackRock’s Bitcoin ETF (IBIT) has reached a new milestone, surpassing 800,000 BTC in assets under management (AUM) in just under two years since its launch. This comes after a remarkable streak of inflows, with the fund seeing over $4 billion in new investments in just one week. With its current AUM valued at approximately $97 billion, BlackRock’s ETF continues to solidify its position as a leader in the U.S. bitcoin market.
Continued Growth and Record Inflows
Since its inception in January 2024, BlackRock’s IBIT spot bitcoin ETF has seen impressive growth. As of October 7, 2025, the fund had accumulated nearly 798,747 BTC, and by October 8, it surpassed the 800,000 BTC mark.
This rapid increase has been fueled by substantial net inflows, with the ETF receiving $426.2 million, or roughly 3,510 BTC, in just one day, pushing its total holdings to approximately 802,257 BTC.
The fund’s current AUM now represents 3.8% of bitcoin’s total supply of 21 million coins. This positions BlackRock’s ETF ahead of other significant players, including Michael Saylor’s corporate treasury, which holds around 640,031 BTC, or 3.1% of the total supply. The fund’s swift growth has captured attention across the financial world, showcasing the increasing demand for bitcoin exposure through regulated investment vehicles.
Bitcoin ETFs Gain Traction in the U.S. Market
The surge in BlackRock’s bitcoin ETF comes as part of a broader trend of growing institutional interest in cryptocurrency. U.S. spot bitcoin ETFs have attracted over $63 billion in inflows since their debut, with IBIT alone accounting for a large portion of that figure.
In just seven days, these funds recorded $5.7 billion in net inflows, marking a significant uptick in participation from institutional investors.
Experts note that the ongoing inflows are indicative of strong and persistent demand for bitcoin as an investment asset. “Corporate treasury participation continues to expand, adding ballast to bitcoin’s narrative as a strategic reserve asset,” said Timothy Misir, Head of Research at BRN. As bitcoin continues to gain traction, market conditions, including reduced geopolitical risks, are also contributing to a more stable environment for investors.
The Competitive Landscape for Bitcoin ETFs
As BlackRock’s IBIT surpasses the 800,000 BTC mark, it also outpaces other bitcoin ETFs in the market. The fund has consistently attracted significant inflows, making it the top performer among all U.S. ETFs.
According to Bloomberg Senior ETF Analyst Eric Balchunas, IBIT’s $3.5 billion in weekly inflows represents 10% of all net ETF flows, further highlighting its strong market position.Additionally, the broader sector has seen growth, with all major spot bitcoin ETFs recording positive inflows in recent weeks.
Even Grayscale’s Bitcoin Trust (GBTC), which had previously struggled with outflows, has benefited from the growing interest in bitcoin ETFs. This increasing demand underscores a broader shift toward bitcoin as an asset class for institutional investors.
Market Conditions and Future Outlook
The recent performance of BlackRock’s bitcoin ETF is also influenced by broader market conditions. The easing of geopolitical risks, particularly through the U.S.-brokered Middle East peace framework, has helped reduce market volatility. This stability has created a clearer path for bitcoin investments, with traders feeling more confident heading into the final quarter of 2025.
Bitcoin’s price has also contributed to the ETF’s success. Since March 2024, when the coin was priced around $69,000, it has surged by 76%, now trading at approximately $121,500. This price increase has helped boost investor confidence, further fueling demand for bitcoin exposure through financial instruments like ETFs.
Overall, BlackRock’s IBIT ETF continues to play a pivotal role in the growing institutional adoption of bitcoin, with sustained inflows demonstrating ongoing interest in the cryptocurrency as a strategic asset. The continued growth of U.S. bitcoin ETFs signals a broader shift in the investment landscape as more institutional investors seek exposure to digital assets.
