The Bitcoin spot ETF market is witnessing a powerful resurgence, with net inflows totaling $2.22 billion between June 23 and June 27, according to data from SoSoValue. The figures, recorded in Eastern Time, reflect mounting investor confidence in Bitcoin as a long-term asset class amid a volatile macroeconomic environment.
Leading the ETF surge is BlackRock’s iShares Bitcoin Trust (IBIT), which registered a remarkable $1.31 billion in net inflows during the week. This boost propels IBIT’s total historical net inflow to $52.31 billion, confirming its status as the institutional favorite among Bitcoin investment vehicles.
The strength of IBIT’s inflows signals sustained institutional interest, driven by a combination of BlackRock’s brand trust, transparent structure, and Bitcoin’s improving fundamentals heading into the second half of 2025.
Fidelity’s Wise Origin Bitcoin Fund (FBTC) also posted strong performance with a $504 million net inflow, bringing its total historical inflows to $11.96 billion. Fidelity continues to establish itself as a dominant force in the Bitcoin ETF market, leveraging its deep investor base and longstanding reputation in the financial sector.
In contrast, Grayscale’s GBTC continued to bleed capital, logging a $5.69 million net outflow last week. Its cumulative net outflows now total $23.25 billion, highlighting investor migration away from high-fee legacy products toward lower-cost, physically-backed ETF structures like IBIT and FBTC.
The total net asset value (NAV) of all U.S.-listed Bitcoin spot ETFs has reached $133.17 billion, amounting to 6.25% of Bitcoin’s total market capitalization. Meanwhile, the cumulative historical net inflow across all Bitcoin ETFs now stands at $48.87 billion, a clear reflection of institutional appetite for regulated Bitcoin exposure.
The latest inflow numbers affirm Bitcoin's growing integration into traditional investment portfolios. As ETFs become the preferred vehicle for institutional access to BTC, the continued success of IBIT and FBTC could spur further product innovation and potentially attract even more capital into the space.
With the total ETF market now commanding a sizable share of Bitcoin’s circulating supply, the impact of these inflows on both price action and long-term market structure will be key narratives heading into Q3 2025.
