BlackRock's iShares Bitcoin Trust (IBIT) attracted roughly $732.6 million in net inflows last week, pushing the fund's total holdings above $62.7 billion and reinforcing its position as the dominant spot Bitcoin ETF by assets.
IBIT pulled in $732.6 million in a single week
The iShares Bitcoin Trust recorded approximately $732.6 million in weekly net inflows, continuing a pattern of steady institutional capital flowing into the product since its January 2024 launch.
IBIT has consistently led the U.S. spot Bitcoin ETF field in attracting new investment. The latest weekly figure places it well above most competing funds in terms of single-week capital intake, according to Farside Investors ETF flow data.
The inflow activity comes as Bitcoin-related investment products continue drawing attention from both institutional allocators and retail investors. Separate developments across the crypto regulatory landscape, including moves like North Carolina's proposed comprehensive crypto bill, suggest a broader environment where digital asset products are gaining mainstream traction.
Holdings now exceed $62.7 billion
The cumulative result of sustained weekly inflows is that IBIT's total holdings have crossed the $62.7 billion threshold. That figure cements the fund as one of the largest ETF launches in history by asset accumulation speed.
The milestone reflects more than a single strong week. It is the product of months of consistent net positive flows that have built IBIT's Bitcoin reserves steadily higher. Each new round of inflows adds directly to the fund's underlying Bitcoin holdings, linking capital demand to on-chain accumulation.
For context, the broader crypto ecosystem has seen significant capital movements recently. Ethereum Foundation's decision to unstake nearly $49 million in ETH illustrates how large entities across the market are actively repositioning their holdings.
What the latest figures signal about Bitcoin fund demand
A weekly inflow of $732.6 million into a single fund suggests that institutional appetite for regulated Bitcoin exposure remains firm. The figure is notable not because it is an outlier, but because it fits within a broader trend of consistent capital allocation to IBIT.
Total holdings surpassing $62.7 billion reinforce that demand has not been a short-lived phenomenon tied to the initial ETF approval excitement. Instead, the fund continues to attract fresh capital more than a year after launch, building on record asset milestones set throughout 2025.
The sustained inflow pattern also has implications for Bitcoin's supply dynamics. As ETF products like IBIT accumulate more Bitcoin in custody, the available circulating supply on exchanges tightens, a factor that market participants watch closely when assessing price support levels.
While enforcement actions like the sentencing of Evan Tangeman to 70 months in a $263 million crypto fraud case highlight ongoing risks in the broader digital asset space, regulated products such as IBIT represent the institutional-grade access point that many allocators have been waiting for.
