BlackRock’s IBIT spot bitcoin ETF crossed 800,000 BTC in assets under management on Wednesday, reaching roughly $97 billion.
The fund cleared the mark after $426.2 million of net inflows on the day pushed its holdings to about 802,257 BTC. IBIT launched in January 2024 and has grown quickly since then.
What moved the needle?
IBIT held more than 798,747 BTC as of Oct. 7, based on its latest disclosures. The day’s inflows of $426.2 million, about 3,510 BTC by CoinGlass counts, were enough to push it past the 800,000 BTC level. That amount equals roughly 3.8% of bitcoin’s total supply of 21,000,000 coins.

The wider group of U.S. spot bitcoin ETFs also saw fresh money. Combined ETF inflows on Wednesday were $440.7 million. The funds have now recorded an eight-day streak that totals more than $5.7 billion. IBIT alone pulled in over $4.1 billion in net inflows during a seven-day stretch.
How IBIT compares to other holders?
BlackRock’s client holdings now outpace some major corporate treasuries. Michael Saylor’s Strategy fund holds about 640,031 BTC, which is worth nearly $78 billion and represents about 3.1% of the total supply. IBIT’s accumulation puts BlackRock’s ETF clearly ahead in bitcoin holdings for clients.
Since launch, U.S. spot bitcoin ETFs have taken in nearly $63 billion in net inflows. IBIT accounts for a large piece of that. Grayscale’s converted fund has seen net outflows that offset some of the total, but IBIT’s inflows remain large.
Market view and sentiment
Analysts see these flows as proof of steady demand from institutional and retail investors. Timothy Misir, head of research at BRN, said the multi-day inflows show lasting structural demand.
He also noted that more corporate treasuries are treating bitcoin as a strategic reserve asset. Misir added that a recent easing of geopolitical risk tied to the Trump-brokered Middle East peace framework has lowered near-term volatility. That, he said, gives traders clearer room to move heading into Q4.
Bloomberg analyst Eric Balchunas highlighted IBIT’s weekly edge. He pointed out that IBIT led weekly ETF flows with $3.5 billion, which he said was about 10% of all net flows into ETFs. Balchunas also noted that all 11 original spot BTC ETFs took cash last week, showing broad appetite.
NovaDius Wealth Management’s Nate Geraci stressed how big the recent inflows are. He said the category pulled in $5.3 billion over the past 7 trading days and $2 billion in the last two days alone. He compared today’s pace to early sceptics who never expected the category to reach such scale.
A milestone path
IBIT passed 500,000 BTC last December and kept growing fast. In March 2024, when it crossed 250,000 BTC, BlackRock CEO Larry Fink called IBIT the fastest-growing ETF in ETF history. He said he was surprised at how much bitcoin had risen.
The steady inflows and large holdings make IBIT a major player in the bitcoin market. The fund now represents a sizable slice of the circulating supply and will be watched closely by traders and institutions alike.
IBIT’s push past 800,000 BTC marks a clear shift in how the market uses ETFs to gain bitcoin exposure. The fund’s rapid growth shows strong demand from many corners of the market.
