The BlackRock Bitcoin ETF (IBIT) has reached a record of $91.06 billion in assets under management (AuM), establishing a new benchmark for U.S. spot Bitcoin ETFs. Data from SoSoValue shows that IBIT's accumulated net inflows amounted to $58.04 billion as of August 13, despite not recording net inflows on any single day on that date. The market price of the ETF closed at $69.84, trading at a 0.57% premium over its net asset value.
The fund currently holds 3.72% of the total Bitcoin supply, solidifying its position as a market leader. IBIT also reported 54.82 million shares on August 13, reaching a total value of $3.79 billion.
Such consistent inflows demonstrate that BlackRock's Bitcoin ETF is a popular vehicle among investors. Both institutional and retail participants use it to gain regulated exposure to Bitcoin.
IBIT has achieved some of the largest inflow milestones since its inception in January 2024. It garnered over $5 billion in net inflows in its debut month, more than any other U.S. ETF launched that year in that month.
BlackRock IBIT reached $80 billion in accumulated net inflows by mid-July 2025, confirming its leadership over the competition. This recent achievement of $58.04 billion in accumulated inflows highlights its unmatched growth trend in the sector.
In addition to BlackRock's Bitcoin ETF, other U.S. Bitcoin ETFs also recorded significant asset totals. FBTC from Fidelity ranks second with $24.77 billion in assets and $12.07 billion in accumulated net inflows. GBTC from Grayscale holds $22.18 billion despite recording $23.72 billion in accumulated outflows.
ARKB from Ark Invest manages $5.58 billion, while BITB from Bitwise holds $5.02 billion. BlackRock's advantage remains considerable, as IBIT's asset base nearly quadruples that of its closest competitor.
