BlackRock Bitcoin ETF hits $91.06B AuM

BlackRock’s iShares Bitcoin Trust (IBIT) has grown to a record $91.06 billion in assets under management, strengthening its lead in the U.S. spot Bitcoin ETF market. The fund continues to attract investors and build its market share, even as Bitcoin’s price drops from its recent all-time highs.

The milestone comes as IBIT’s total net inflows reached $58.04 billion by August 13, showing strong investor interest even though there were no new inflows on that specific day. On the same date, the ETF ended trading at $69.84 per share, which was 0.57% higher than its net asset value, reflecting steady demand in the market.

BlackRock grows its Bitcoin ETF to record assets and widens its lead

BlackRock’s iShares Bitcoin Trust secured its position as the undisputed leader in the U.S. spot Bitcoin ETF market after reaching an unprecedented $91.06 billion in assets under management. IBIT has proved investors’ trust in BlackRock and its ability to capture market share in a fiercely competitive space by holding 3.72% of the total Bitcoin supply (roughly 54.82 million shares valued at $3.79 billion). 

IBIT has displayed incredible momentum and attracted all types of investors from large institutions to retail participants since its debut in January 2024. The ETF set a record for any new U.S. ETF launched in its first month by achieving over $5 billion in net inflows. 

IBIT had already crossed the $80 billion mark in cumulative net inflows by mid-July 2025. The jump to $91.06 billion in August further underscored its unmatched ability to attract and retain investor capital even in volatile market conditions.

Other spot Bitcoin ETFs have posted solid growth figures, but none have come close to matching IBIT’s scale. Fidelity’s FBTC ranks second and manages $24.77 billion in assets with $12.07 billion in cumulative net inflows. Even though its performance is exceptional, it still represents less than one-third of BlackRock’s total.

Grayscale’s GBTC holds $22.18 billion in assets but recorded $23.72 billion in cumulative outflows since its conversion to an ETF. Ark Invest’s ARKB and Bitwise’s BITB remain relatively small players, catering to narrower investor segments with $5.58 billion and $5.02 billion, respectively.

Hot U.S. inflation data pushes Bitcoin down and triggers $1B in losses

Bitcoin’s latest rally reached a dramatic high of $124,000 on Wednesday, largely due to investor optimism that the U.S. Federal Reserve would soon deliver a 25 basis point interest rate cut. Traders believed this move would strengthen demand for cryptocurrencies, encourage risk-taking, and inject fresh liquidity into financial markets. 

However, the Federal Reserve had to maintain a more cautious approach to monetary easing when the month’s U.S. Producer Price Index (PPI) data came in hotter than expected. As a result, Bitcoin’s price plunged below $118,000 in a matter of minutes and sparked a chain reaction that rippled through spot markets, futures contracts, and the entire cryptocurrency ecosystem.

Automatic liquidation systems on major exchanges closed positions to meet margin requirements and prevent further losses to lenders as Traders slipped into loss territory. The total crypto liquidation amount crossed the $1 billion mark in less than 24 hours, with more than $930 million in leveraged Bitcoin positions alone. 

The price drop translated almost immediately into a downward adjustment of IBIT’s net asset value since each share rises and falls with changes in the spot price. However, many of the ETF’s holders view such price dips as opportunities to accumulate more shares at relatively lower prices because it still managed to attract investor inflows even during heightened volatility.

This distinction between IBIT and many of its competitors reinforces the idea that IBIT’s investor base comprises participants committed to long-term exposure rather than short-term speculation.
