BlackRock on a crypto buying spree with over $560 million Bitcoin haul in 5 days

BlackRock’s (NYSE: BLK) iShares Bitcoin Trust (NASDAQ: IBIT) recorded over $560 million in net Bitcoin (BTC) inflows in a week as institutional investors showed renewed interest in the maiden cryptocurrency. Specifically, the fund attracted $565. 7 million in net inflows over five trading sessions from October 19 to October 23, making it the strongest-performing fund in the U.

S. spot Bitcoin ETF market over the period. Despite IBIT’s gains, the broader U.

S. spot Bitcoin ETF market recorded a smaller net inflow of $301. 2 million.

IBIT attracted $665. 2 million on October 19, its largest single-day inflow since October 2025. It recorded another $29.

9 million on October 20 and $235 million on October 21. The trend reversed on October 22, when IBIT registered $254. 1 million in net outflows, followed by another $110.

3 million on October 23. Despite the withdrawals, the fund ended the period with $565. 7 million in net inflows.

Overall, U. S. spot Bitcoin ETFs attracted $1.

8 million on October 21. The market then recorded $635. 6 million in outflows on October 22, its largest single-day withdrawal since June, followed by another $137.

9 million on October 23. The rebound reflects growing institutional demand for Bitcoin ETFs, which have overtaken corporate treasuries as a source of Bitcoin buying, according to Coinbase Institutional’s October 23 commentary. Corporate treasuries bought approximately $14.

5 billion in Bitcoin during the first half of 2026, while U. S. spot ETFs recorded nearly $5 billion in net selling.

Since August, ETFs have attracted about $6. 4 billion, compared with $1. 5 billion for corporate treasuries.

Macroeconomic pressures remain a risk as U. S. producer prices rose 1.

3% month over month in September, their largest increase since March 2022, while markets priced in a higher probability of a Federal Reserve rate hike in December. Higher rates could weigh on Bitcoin by tightening financial conditions and making yield-bearing assets more attractive. Meanwhile, Coinbase Institutional identified $80,000 to $82,000 as a key support zone, citing ETF holders’ estimated cost basis of $81,300 and the 50-day moving average (MA) near $81,700.

A sustained break below this range could expose Bitcoin to further losses toward $73,000 to $75,000. Ethereum ETF records outflows On the other hand, Ethereum (ETH) ETFs recorded $220. 7 million in net outflows over the five sessions, despite attracting $4.

4 million on October 23. BlackRock’s iShares Ethereum Trust (NASDAQ: ETHA) accounted for $233. 2 million in outflows, losing $95.

4 million on October 19, $33 million on October 20, $29. 3 million on October 21 and $75. 5 million on October 22.
