Wall Street investment giant BlackRock’s spot Bitcoin exchange-traded fund (ETF), iShares Bitcoin Trust (NASDAQ: IBIT), surpassed 700,000 BTC in assets under management after the ETF registered another $164.6 million in inflow on Monday.
According to the official iShares website, IBIT had accumulated 698,919 BTC, worth $76.15 billion, on July 3. It then saw around 1,510 BTC in net inflows when the markets reopened yesterday following the three-day Independence Day weekend in the United States. This brought the asset manager’s total holdings under its spot Bitcoin ETF to 700,307 BTC, valued at $76.30 billion.
BlackRock’s IBIT Now Holds 700K+ BTC, Becomes Firm’s Third-Top ETF
The fund now accounts for more than 55% of the total Bitcoins held under the 12 Spot Bitcoin ETFs currently trading in the US. The Fidelity Wise Origin Bitcoin Fund ETF (CBOE: FBTC) is the second-largest, with 203,508 BTC ($22.18 billion) in assets under management, followed by Grayscale Bitcoin Trust (NYSE: GBTC) with 184,226 BTC ($20.08 billion) in AUM.
IBIT is now the third-highest revenue-generating ETF for BlackRock under its iShares brand, which manages over 1,400 ETFs tracking 800 different financial products, and is only $9 billion shy of its number one product, the iShares Russel 1000 Growth ETF (IWF), which is a $104.58 billion fund measuring the performance of large and mid-cap growth sectors of the US stock market.
What makes this feat even more remarkable is that IBIT has only been on the market for 18 months. Since its launch in January 2024, the fund has delivered a total ROI of 82.67%.
Just last week, Bloomberg reported that IBIT now earns more revenue for BlackRock than its flagship product, the iShares Core S&P 500 ETF (IVV), which debuted in 2000 and manages over $624 billion in assets. The company’s spot Bitcoin ETF managed to earn $100,000 more in annual fees at $187.2 million, compared to IVV’s $187.1 million, despite having a higher expense ratio, reflecting the growing investor demand for BTC and their willingness to pay more for regulated exposure to the best-performing financial asset in the world.
IBIT managed to overtake Grayscale’s GBTC by AUM within months of its debut, despite the latter having a headstart over the other US spot Bitcoin ETFs in assets before its conversion to an ETF.
IBIT Accounts for 56% of the 1.25 Million BTC Held By All US Spot Bitcoin ETFs
According to data from CoinGlass, the combined assets held by all spot Bitcoin ETFs in the US now stand at approximately 1.25 million BTC, which is worth $135 billion. This lot represents nearly 6% of the apex cryptocurrency’s 21 million total supply. IBIT accounts for 56% of that AUM alone, with only Strategy’s (formerly MicroStrategy) treasury stack of 597,325 BTC ($65 billion) coming close in comparison.
On Monday, the US Spot Bitcoin ETFs also surpassed $50 billion in cumulative inflow since their debut in January 2024 and $14.5 billion year-to-date after the funds added another $1.2 billion over the past three trading days. The combined ETFs generated $407.8 million in net inflows on Wednesday, July 2, followed by another $601.8 million on Thursday, July 3. IBIT also leads the chart in combined inflows with $52.9 billion.
The Bitcoin ETFs also generated $5.3 billion in trading volume on Thursday, their highest since May, which was once again led by IBIT with $4.1 billion. Cumulative trading volume for the funds since their launch now stands at over $1 trillion. IBIT also accounted for around 80% of the $2.9 billion in trading volume on July 7.
A recent report by Galaxy Research stated that US Bitcoin ETFs and Michael Saylor’s Strategy, the largest corporate holder of Bitcoin, have combined to purchase more BTC than the supply generated by miners from block rewards every month of 2025, except February.
At the time of writing, Bitcoin (BTC) is trading at $108,809, up 0.21% in the last 24 hours. The iShares Bitcoin Trust ETF (IBIT) closed Monday’s trading session at $61.40, down 0.60%.
