BlackRock's IBIT Bitcoin ETF records $665 million one‑day inflow, the largest since October 2025
On October 19 2026 BlackRock’s iShares Bitcoin Trust (IBIT) logged a net inflow of $665.16 million, its biggest single‑day addition since October 7 2025. The fund’s assets now total $66.37 billion, while total U.S. spot Bitcoin ETFs saw net inflows of $526.6 million and spot Ether ETFs posted $103.3 million of outflows. Bitcoin’s price fell 1.61% to $81,421 despite the fund’s inflow, suggesting the money largely shifted from rival ETFs rather than representing fresh demand.
Why it matters
The inflow highlights a reshuffle of capital within the U.S. spot Bitcoin ETF market rather than new institutional buying, which may limit any immediate upside for Bitcoin’s price (the coin slipped 1.61%). The record inflow also reinforces IBIT’s dominance, potentially attracting further investor attention to BlackRock’s crypto offerings.
