BlackRock’s IBIT Surpasses 800,000 BTC, Cementing Its Lead in Institutional Bitcoin Adoption

BlackRock’s spot Bitcoin exchange-traded fund (IBIT) has surpassed 800,000 BTC in assets under management, following an eight-day inflow streak that brought in over $4 billion. The milestone marks a significant step in institutional adoption of Bitcoin, coming less than two years after the fund’s launch in January 2024.

BlackRock’s IBIT Now Holds 3.8% of Bitcoin Supply Amid Record Inflows

According to the latest disclosures, BlackRock’s IBIT held approximately 802,257 BTC as of Wednesday, valued at around $97 billion. The ETF received $426.2 million (about 3,510 BTC) in net inflows on Tuesday alone, pushing it beyond the 800,000-BTC threshold . The holdings now represent 3.8% of Bitcoin’s fixed 21-million supply.

This achievement places BlackRock’s Bitcoin fund well ahead of Michael Saylor’s MicroStrategy, which holds 640,031 BTC (roughly $78 billion), accounting for 3.1% of total supply. The rapid growth underscores how quickly regulated investment vehicles have come to dominate institutional Bitcoin exposure.

Across all U.S. spot Bitcoin ETFs, inflows totaled $440.7 million on Wednesday, contributing to an eight-day run exceeding $5.7 billion, according to data from The Block. Of that, IBIT alone has attracted more than $4.1 billion in net inflows over the past week.

Eight-Day Bitcoin ETF Inflow Streak Reinforces Institutional Bullishness

Timothy Misir, Head of Research at BRN, said the recent eight-day streak of ETF inflows highlights sustained structural demand for Bitcoin . He noted that growing corporate treasury participation is strengthening Bitcoin’s position as a strategic reserve asset. At the time of writing, Bitcoin is trading at around $122,500 following a 97% surge in the past year.

The eight-day streak of ETF inflows underscores persistent structural demand, while corporate treasury participation continues to expand, adding ballast to Bitcoin’s narrative as a strategic reserve asset.

Misir added that easing geopolitical risks, following the Trump-brokered Middle East peace framework, has helped reduce short-term volatility, giving traders a clearer outlook heading into Q4.

BlackRock’s IBIT Leads ETF Inflows as BTC Funds Log $1.21B in a Single Day

On Monday, Bitcoin ETFs logged their largest daily inflow since Donald Trump’s pro-crypto election victory last November, pulling in $1.21 billion. Since their launch, U.S. spot Bitcoin ETFs have recorded nearly $63 billion in cumulative inflows—led by BlackRock’s IBIT with approximately $65 billion—though outflows from Grayscale’s converted fund have slightly offset the total.

Nate Geraci, President of NovaDius Wealth Management, noted that spot Bitcoin ETFs are experiencing unprecedented momentum, with $5.3 billion in inflows over the past seven trading days, including $2 billion in just the last two. In his view, the surge has surpassed early expectations , proving wrong initial skeptics who predicted the category would peak at $5 billion.

In a Wednesday post, Bloomberg Senior ETF Analyst Eric Balchunas reported that IBIT led all ETFs in weekly inflows , capturing $3.5 billion—about 10% of total net flows across all ETF products. Balchunas added that even Grayscale’s GBTC recorded inflows during the week, reinforcing the strength of current market demand.

In another milestone, IBIT has also become the world’s largest Bitcoin options platform , holding $38 billion in open interest and surpassing Deribit, which was recently acquired by Coinbase.
