IBIT Breaks 800,000 BTC Barrier
BlackRock, the world’s biggest asset manager, now holds 802,200 BTC in its IBIT ETF, according to Apollo co-founder Thomas Fahrer. The fund had amassed 798,747 BTC as of Oct. 7, per BlackRock’s own iShares website. IBIT’s purchase of 3,510 BTC (worth $426.2 million) yesterday was enough to push its total holdings above the 800K milestone. The market-leading ETF now holds roughly 3.804% of Bitcoin’s total 21 million supply.
IBIT accounts for over 55% of the total BTC held in US spot Bitcoin ETFs, data from Bitbo shows. Additionally, the BlackRock ETF holds more than Michael Saylor’s Strategy, the largest corporate holder of Bitcoin, which boasts a 640,031 BTC stockpile (valued at roughly $78 billion).
The recent Bitcoin milestone comes amid reports that IBIT has become BlackRock’s most profitable ETF, surpassing the revenue of its flagship S&P 500 fund, the iShares Core S&P 500 ETF, which debuted in 2000.
IBIT Leads Weekly Inflows
Meanwhile, IBIT has led the charge in weekly inflows among all U.S.-listed spot Bitcoin ETFs, as pointed out by Bloomberg’s senior ETF analyst Eric Balchunas.
 
“IBIT is #1 in weekly flows among all ETFs with $3.5 billion, which is 10% of all net flows into ETFs,” Balchunas wrote in a Wednesday X post. “Also notable is the rest of the 11 OG spot BTC ETFs all took in cash in the past week, even GBTC, somehow; that’s how hungry the fish are. Two steps forward mode. Enjoy while it lasts.”
On Monday, the dozen BTC ETFs pulled in their biggest daily inflow since crypto-friendly President Donald Trump secured the presidency against Kamala Harris as institutional appetite for crypto exposure continues to build. These funds have now posted cumulative net inflows of $63 billion since their launch, with IBIT taking in $65 billion, offset by net outflows from Grayscale’s Bitcoin Trust (GBTC).
