• BlackRock’s iShares Bitcoin Trust (IBIT) had a record $2.63 billion inflow in Q3 2025, the highest for any Bitcoin ETF.
• Increased demand for regulated cryptocurrency ETFs shows rising institutional confidence in digital assets.
• The inflows happened as BTC reached an all-time high of over $126,000, boosting its image as a store of value.

BlackRock’s iShares Bitcoin Trust (IBIT) has witnessed a spectacular boost in investor appetite, making it the top Bitcoin exchange-traded fund (ETF) in the United States. IBIT saw a record $2.63 billion inflow in the third quarter of 2025, the largest weekly inflow ever for any BTC ETF.

Institutional Demand Fuels Record Inflows

IBIT’s strong performance is a reflection of the increasing institutional demand for regulated cryptocurrency investment products. Investors are increasingly preferring ETFs such as IBIT for their regulatory transparency, custodial protection, and streamlined accounting, which enable direct exposure to cryptocurrency without the operational intricacies of self-custody.

As of October 13, 2025, IBIT’s assets under management (AUM) totaled around $93 billion, equivalent to approximately 3.8% of BTC’s total supply.

BlackRock’s Strategic Position within Digital Assets

IBIT’s success is part of a larger trend among digital assets. BlackRock’s digital asset exchange-traded funds, such as IBIT and the iShares Ethereum Trust (ETHA), accumulated $17 billion in net inflows in the third quarter of 2025, for a year-to-date total of $34 billion. The expansion highlights growing institutional faith in cryptocurrencies as assets for investment.

Market Dynamics and Bitcoin’s (BTC) Price Surge

The increase in IBIT’s inflows has coincided with a major price rally in BTC’s price, which recently crossed $126,000, setting an ATH. The price increase has been caused by reasons such as softening of geopolitical risks, involvement of treasuries, and an increasing understanding of BTC as a store of value and inflation hedge, similar to gold.

In conclusion, BlackRock’s iShares Bitcoin Trust has not just recorded record inflows but has also been instrumental in facilitating institutional Bitcoin adoption. IBIT, with its mammoth AUM and sustained growth, is set to remain a key driver in the changing world of cryptocurrency investment.
