- IBIT now holds more than 700,000 BTC, worth approximately $75.5 billion at current prices.
- Since its launch in January 2024, IBIT has become the dominant U.S. spot Bitcoin ETF.
- According to Bitbo data, it now represents over 55% of the total BTC held across all U.S. spot Bitcoin ETFs.
BlackRock’s iShares Bitcoin Trust (IBIT) has surpassed 700,000 Bitcoin in holdings, marking a major milestone for the spot Bitcoin exchange-traded fund.
Blockchain analytics platform Glassnode reports that IBIT currently holds 700,000 BTC, valued at roughly $75.5 billion at today’s prices.
The asset milestone followed a net inflow of $164.6 million into the fund on Monday.
Outpaces other Bitcoin ETFs and corporate treasuries
Since launching in January 2024, IBIT has established itself as the leading U.S. spot Bitcoin ETF.
Data from Bitbo indicate that IBIT accounts for more than 55% of all BTC held by U.S. spot Bitcoin ETFs combined.
IBIT’s 18-month growth trajectory places it ahead of other major funds in the category, including Fidelity’s FBTC, which holds about 203,000 BTC, and a gray-area holding of GBTC at roughly 184,000 BTC.
The ETF’s holdings also eclipse those of Michael Saylor’s MicroStrategy (MSTR), a corporate seller-turned-accumulator that began acquiring 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.
Revenues surpass BlackRock’s flagship S&P 500 ETF
BlackRock’s Bitcoin ETF is now one of the firm’s top-performing products.
IBIT has become the third-highest revenue-generating ETF across BlackRock’s lineup, which includes more than 1,100 funds.
It reportedly now produces higher revenues for the asset manager than iShares Core S&P 500 ETF (IVV), BlackRock’s flagship fund that tracks the U.S. equity benchmark, and iShares Russell 2000 ETF (IWM), which tracks U.S. small-cap stocks.
“New milestone, iShares Bitcoin ETF now holds more than 700,000 BTC. 700,000. That took 18 months. Ridiculous,” wrote Nate Geraci, president of The ETF Store, on X.
Bloomberg ETF senior analyst Eric Balchunas also highlighted IBIT’s rise within BlackRock’s rankings, noting its rapid emergence as a core product in the firm’s ETF offering.
IBIT’s swift growth coincides with robust demand for U.S. spot Bitcoin ETFs, which since their January 2024 debut have attracted over $50 billion in net inflows collectively.
Those ETFs are widely regarded as one of the most successful ETF launches in U.S. financial history.
Research from Galaxy Digital shows combined buying activity from U.S. Bitcoin ETFs and related strategies has consistently outpaced net new Bitcoin issuance from miners.
In 2025 alone, these entities purchased $28.22 billion worth of Bitcoin, compared with $7.85 billion in new coins generated by miners.
Galaxy noted that the supply-demand imbalance persisted every month except February, when the group recorded net Bitcoin sales totaling $842 million.
