BlackRock's $11.6T Valuation Backs $5.4B Bitcoin Surge, IBIT ETF on 16-Day Inflow Streak

BlackRock Inc., with a market valuation of $11.6 trillion, has significantly increased its Bitcoin holdings, with its iShares Bitcoin Trust (IBIT) ETF purchasing over $5.4 billion worth of Bitcoin-related assets, according to a recent 13F filing. The firm's aggressive accumulation continued last week, with IBIT acquiring $2.5 billion worth of Bitcoin, averaging $500 million daily. On May 2, IBIT alone saw a substantial inflow of $674.91 million, while other Bitcoin ETFs recorded no inflows, highlighting BlackRock's dominant position in the Bitcoin ETF market. The firm's ETF has been on a 16-day inflow streak, adding a total of $4.6 billion during this period, with 47,064 BTC purchased since April 21. BlackRock's latest purchase on May 5 was 5,613 Bitcoin valued at approximately $531.2 million, bringing its total holdings to 614,339 Bitcoin, valued at around $58.03 billion. This consistent buying has led to BlackRock's IBIT ETF surpassing the inflows of its gold ETF in 2025, despite Bitcoin's year-to-date performance being significantly lower than gold's. The broader market for digital asset investment products saw $2 billion in inflows last week, with Bitcoin attracting $1.8 billion of that total. On May 5, around 4,520 BTC were bought, contributing to $425.5 million in net inflows for Bitcoin ETFs. However, on May 6, Bitcoin ETFs experienced a net outflow of $85.7 million, with 905 BTC sold, and Ethereum ETFs saw $17.9 million in outflows, with 9,840 ETH sold, indicating a shift in investor sentiment. Additionally, BlackRock made a $37.8 million Bitcoin purchase on May 7.
