Catenaa, Wednesday, October 15, 2025- BlackRock spot bitcoin exchange-traded fund, IBIT, has surpassed 800,000 BTC under management, marking a new milestone in institutional bitcoin adoption after an extended streak of inflows totaling more than $4 billion.
The fund, which began trading in January 2024, now holds roughly 802,198 BTC worth about $97 billion, representing 3.8% of bitcoin’s total 21 million supply.
IBIT’s assets rose after $426 million in fresh inflows on Tuesday, pushing it beyond the threshold, according to BlackRock’s latest disclosures.
The surge positions BlackRock ahead of Strategy, the bitcoin treasury firm led by Michael Saylor, which holds 640,031 BTC valued near $78 billion.
Combined US spot bitcoin ETFs attracted $440.7 million in inflows Wednesday, extending an eight-day streak that has brought in over $5.7 billion in new capital.
Bloomberg ETF analyst Eric Balchunas said IBIT led all ETFs globally in weekly inflows with $3.5 billion, accounting for 10% of total net ETF flows.
Bitcoin ETFs also recorded their strongest daily inflows since President Donald Trump’s election victory last November, adding $1.21 billion on Monday.
Since launch, IBIT has drawn nearly $65 billion in cumulative inflows and ranks among the fastest-growing ETFs in history.
