“Even amid short-term market corrections, investors continue to trust IBIT’s stability and liquidity,” said a market analyst.
This sustained demand highlights growing confidence in BlackRock’s Bitcoin ETF. With $93.98 billion in net assets, IBIT controls about 4.13% of Bitcoin’s market cap. The ETF’s ability to withstand volatility positions it as a long-term option for institutional investors.
Other Bitcoin ETFs See Outflows
While IBIT surged, other Bitcoin ETFs faced outflows. Fidelity’s FBTC experienced a $10.18 million outflow, while Grayscale’s GBTC saw a larger $19.21 million withdrawal. This marks a continuation of Grayscale‘s struggle following its conversion from a trust to an ETF. Smaller players, such as Ark 21Shares and the Grayscale BTC fund, reported modest outflows of $5-6 million each.
The overall net inflow across all Bitcoin ETFs reached $62.77 billion as of October 10. Despite a slight outflow of $4.5 million on the day, the Bitcoin ETF market remains strong. Total assets in Bitcoin ETFs reached nearly $159 billion, which represents 7% of Bitcoin’s total market cap.
IBIT Leads the Institutional Shift to Bitcoin ETFs
BlackRock’s IBIT is leading the charge as traditional finance firms increasingly turn to Bitcoin ETFs. With a low 0.25% management fee, IBIT offers deep liquidity and exposure to Bitcoin. It has become the ETF of choice for traditional financial institutions entering the cryptocurrency market.
Fidelity’s FBTC, while holding $24.19 billion in assets, remains far behind IBIT in scale. However, the race for Bitcoin ETF dominance reflects the broader trend of growing institutional adoption of cryptocurrency. As capital continues to flow into Bitcoin ETFs, the institutional narrative surrounding Bitcoin strengthens. The competition between firms like BlackRock, Fidelity, and Grayscale will likely intensify in the coming months.
