Key Takeaway

BlackRock’s iShares Bitcoin Trust (IBIT) cements its dominance in the U.S. spot Bitcoin ETF race, reaching an unprecedented $91.06 billion in assets under management.

BlackRock’s iShares Bitcoin Trust (IBIT) has achieved a record milestone in the U.S. spot Bitcoin [BTC] ETF market, amassing $91.06 billion in assets under management (AUM).

Despite Bitcoin’s recent pullback from record highs, the fund’s total net inflows have soared to $58.04 billion as of the 13th of August, underscoring robust investor confidence.

BlackRock’s Bitcoin ETF hits record high

Despite no fresh inflows on the 13th of August, IBIT closed at $69.84 per share, 0.57% above its net asset value, reflecting continued market demand.

The iShares Bitcoin Trust now holds 3.72% of all circulating Bitcoin, reinforcing its status as the leading spot Bitcoin ETF.

At press time, IBIT reported 54.82 million outstanding shares, valued at a combined $3.79 billion.

Since its January 2024 launch, IBIT has seen explosive growth, attracting both institutional giants and retail investors. 

It broke the U.S. ETF launch record with over $5 billion in net inflows during its first month, and by mid-July 2025, cumulative inflows had exceeded $80 billion.

Other Bitcoin ETFs’ status

Fidelity’s FBTC ranks second, managing $24.77 billion in assets and attracting $12.07 billion in net inflows. 

Grayscale’s GBTC follows with $22.18 billion in assets but has experienced $23.72 billion in outflows since transitioning to an ETF.

Meanwhile, Ark Invest’s ARKB and Bitwise’s BITB hold smaller market shares, with $5.58 billion and $5.02 billion in assets, respectively.

Factors involved

That being said, the recent turbulence in Bitcoin’s price underscores the market’s sensitivity to macroeconomic shifts, with the latest pullback driven by hotter-than-expected U.S. PPI data.

Bitcoin’s sharp drop from near $124,000 to below $119,000 not only erased over $930 million in leveraged BTC positions, but also triggered more than $1 billion in overall crypto liquidations, at press time.

However, as Bitcoin was dropping, Ethereum [ETH] seized the spotlight on Wall Street, with U.S. spot ETH ETFs raking in a record-breaking $1.019 billion in net inflows on the 11th of August, surpassing even their Bitcoin-focused rivals.

Even here, BlackRock’s iShares Ethereum Trust (ETHA) led the charge and surpassed $10 billion in cumulative net inflows, doubling its previous $5 billion tally in just three months.

It now holds over 3.3 million ETH, highlighting a growing investor appetite for the second-largest cryptocurrency.
