The iShares Bitcoin Trust (IBIT) from BlackRock has surpassed 700,000 bitcoins in holdings, marking a major milestone for the spot Bitcoin exchange-traded fund.
Blockchain data platform Glassnode reports IBIT now holds 700,000 BTC, worth approximately $75.5 billion at current market prices.
This asset milestone followed a net inflow of $164.6 million into the fund on Monday.
Surpassing other Bitcoin ETFs and corporate treasuries
Since its debut in January 2024, IBIT has emerged as the top spot Bitcoin ETF in the U.S.
It accounts for over 55% of the total BTC held within all U.S. spot Bitcoin ETFs, per Bitbo’s figures.
IBIT’s 18-month growth trajectory places it ahead of other leading funds in the category, such as Fidelity’s FBTC, which holds roughly 203,000 BTC, and Grayscale’s GBTC, holding about 184,000 BTC.
The ETF has also eclipsed the Bitcoin holdings of MicroStrategy (MSTR), which began accumulating Bitcoin in 2020 and currently holds around 600,000 BTC.
MicroStrategy remains the largest corporate holder of Bitcoin to date.
Since inception, IBIT has delivered a total return of 82.67%, according to fund performance data tracked by market analysts.
Revenue now exceeds flagship S&P 500 ETF
BlackRock’s Bitcoin ETF has become one of the asset manager’s strongest-performing products.
IBIT is now the third most profitable ETF in BlackRock’s lineup, which includes more than 1,100 funds.
It reportedly generates more revenue for the asset manager than the iShares Core S&P 500 ETF (IVV), BlackRock’s flagship U.S. equity index fund, as well as the iShares Russell 2000 ETF (IWM), which tracks small-cap U.S. stocks.
“New milestone: iShares Bitcoin ETF now holds over 700,000 BTC. 700,000. They did it in 18 months. Ridiculous,” wrote Nate Geraci, president of The ETF Store, on X.
Eric Balchunas, senior ETF analyst at Bloomberg, also highlighted the significance of IBIT’s rapid rise within BlackRock’s ETF rankings, noting its swift emergence as a flagship product.
IBIT’s fast growth coincides with strong demand for spot Bitcoin ETFs in the U.S., which collectively have attracted more than $50 billion in net inflows since launching in January 2024.
These funds are regarded as among the most successful ETF launches in U.S. financial history.
A Galaxy Digital study found combined purchasing activity from ETFs and the U.S. Bitcoin strategy has consistently exceeded miners’ new net issuance of Bitcoin.
In 2025 alone, those entities purchased $28.22 billion worth of Bitcoin, compared with $7.85 billion of new Bitcoin generated by miners.
Galaxy noted this supply-demand imbalance persisted every month except February, when the group recorded net Bitcoin sales totaling $842 million.
