The iShares Bitcoin Trust (IBIT), managed by BlackRock, has reached a significant milestone by surpassing 700,000 bitcoins in assets. This achievement positions IBIT as the leading spot Bitcoin exchange-traded fund (ETF) in the United States, with notable implications for the cryptocurrency market.
IBIT’s Significant Rise
- IBIT now holds over 700,000 BTC, valued at approximately $75.5 billion at current prices.
- Since its launch in January 2024, IBIT has emerged as the dominant spot Bitcoin ETF in the U.S.
- It accounts for more than 55% of total Bitcoin held across all American spot Bitcoin ETFs, according to Bitbo data.
According to blockchain analytics platform Glassnode, the IBIT fund reached this asset threshold following a net inflow of $164.6 million observed this past Monday.
Leading the ETF Market
Since its inception in January 2024, IBIT has established itself as the foremost spot Bitcoin ETF in the United States. It commands over 55% of the total Bitcoin assets held across existing American spot Bitcoin ETFs, surpassing notable competitors in the sector.
With a total of approximately 203,000 BTC, Fidelity’s FBTC trails behind, followed by Grayscale’s GBTC, which holds about 184,000 BTC. Furthermore, IBIT has outpaced Michael Saylor’s MicroStrategy (MSTR), which has been accumulating Bitcoin since 2020 and currently holds about 600,000 BTC.
Since its launch, IBIT has achieved a total return of 82.67%, reflecting its robust performance in the highly competitive ETF landscape.
Revenue Performance Outpaces Major Indices
The BlackRock Bitcoin ETF is now one of the company’s top-performing products, ranking as the third most profitable ETF within BlackRock’s extensive portfolio of over 1,100 funds. Notably, IBIT generates more revenue than the flagship iShares Core S&P 500 ETF (IVV) and the iShares Russell 2000 ETF (IWM).
Experts in the field have taken notice of IBIT’s rapid ascent. Nate Geraci, president of The ETF Store, remarked on social media, “New milestone, iShares Bitcoin ETF now holds over 700,000 BTC. 700,000. Made it in 18 months. Ridiculous.”
Also notable is Eric Balchunas, a senior ETF analyst at Bloomberg, who emphasized IBIT’s swift rise within BlackRock’s ETF offerings, highlighting its growing importance in the market.
This growth trajectory aligns with increasing demand for spot Bitcoin ETFs in the U.S., which have collectively attracted over $50 billion in net inflows since their inception in January 2024. These ETFs have been heralded as one of the most successful product launches in the history of American finance.
According to a report by Galaxy Digital, the combined purchasing activity of American Bitcoin ETFs has consistently exceeded the net new Bitcoin issuance from miners, showcasing the strong market demand. In 2025 alone, these entities purchased $28.22 billion worth of Bitcoin, compared to just $7.85 billion generated by miners.
