IBIT maintains dominance amid fee competition
BlackRock's IBIT holds $67.82 billion in assets under management despite growing pressure from low-cost alternatives like Morgan Stanley's MSBT. While Fidelity's FBTC remains a primary rival, IBIT maintains massive dominance in the US spot Bitcoin ETF market.
I see BlackRock’s iShares Bitcoin Trust (IBIT) maintain its massive dominance in the US spot Bitcoin ETF market despite recent price volatility. On October 2, 2026, the IBIT price is $47.72, a slight drop from the $47.96 closing price on October 1. While IBIT recorded a massive single-day inflow of $970.9 million on April 28, the fund recently maintained an unusual 20-day inflow streak that successfully brought in over $5 billion in total capital for its diverse group of institutional participants. The fund holds $67.82 billion in assets under management, and its year-to-date flows reach $3.30 billion. The February 2026 drawdown, when Bitcoin fell below $61,000, tested the tracking accuracy and resilience of every fund in the category. I also see that IBIT experienced $9.5 million in net outflows on a Wednesday in September. Bitcoin remains above the May low of $74,156.43, and the price of $102,765.48 sits near the $102,000 support level. Smaller issuers struggle to attract capital, and their long-term viability is questionable.
The rivalry with FBTC
Fidelity’s Wise Origin Bitcoin Fund (FBTC) remains the primary rival, but its scale is much smaller than BlackRock’s. I see FBTC at a price of $73.30 today, compared to its $73.61 close on October 1. Its assets under management total $15.50 billion, which leaves it far behind IBIT. Both products charge a 0.25% expense ratio, so I see no cost advantage for either. I also see that FBTC has struggled with negative momentum this year, as it shows -$1.23 billion in year-to-date flows. You should focus on the fact that IBIT’s two-year growth of $1,000 is $1,040, while FBTC’s growth is slightly higher at $1,042. Both funds show nearly identical year-to-date performance, with IBIT down 3.21% and FBTC down 3.26%. IBIT uses Coinbase for custody, while FBTC uses Fidelity Digital Assets. IBIT also launched its options in November 2024, and those options processed over 2 million contracts in a single session during the February 2026 volatility. I see the IBIT and FBTC performance closely; while IBIT is significantly larger by assets under management, its liquidity is deeper than its rivals.
| Metric | IBIT | FBTC |
|---|---|---|
| Price (10/2/26) | $47.72 | $73.30 |
| AUM | $67.82 B | $15.50 B |
| Expense Ratio | 0.25% | 0.25% |
| YTD Flows | $3.30 B | -$1.23 B |
| YTD Performance | -3.21% | -3.26% |
Pressure from low-cost alternatives
The pressure on IBIT and FBTC is increasing because of the Morgan Stanley Bitcoin Trust (MSBT) and its aggressive pricing. MSBT launched on April 8, 2026, with an expense ratio of 0.14%. This fee is 11 basis points lower than IBIT’s 0.25% fee. MSBT is the first spot Bitcoin ETF issued by a major U.S. bank, and its assets under management reached $299 million as of June 30, 2026. I see that MSBT also holds 5,059 BTC. VanEck’s HODL also lost its sponsor fee waiver on July 31, 2026, when its fee returned to 0.20%. While analysts like Eric Balchunas argue that IBIT has enough pricing power to ignore these smaller rivals, the margin is shrinking. MSBT’s 0.14% fee undercuts the 0.15% fee of Grayscale’s Bitcoin Mini Trust. The competition in the fee landscape is a new phase for the industry. I see that the entire category has absorbed over $70 billion in cumulative net inflows since its launch in January 2024. Can BlackRock defend its market share if more banks launch products at 0.14%?
