BlackRock IBIT Pulls $665 Million in a Day as Bitcoin ETFs Net $527 Million, Their Best Showing Since September

U.S. spot Bitcoin ETFs recorded $526.7 million in net inflows on October 19, their largest single-day intake in nearly a month and the best result since September, snapping two consecutive weeks of net weekly withdrawals. The rebound was driven almost entirely by BlackRock's iShares Bitcoin Trust, known as IBIT, which alone drew $665.2 million, its biggest single-day inflow since October 7, 2025 and a figure that exceeded the combined net total across all funds. Those gains were partially offset by $83.6 million in outflows from Fidelity's Wise Origin Bitcoin Fund (FBTC) and $54.9 million from Grayscale's Bitcoin Trust (GBTC), with all other funds recording no net flows.

Despite the sharp inflow surge, Bitcoin's price response was muted. The coin rebounded from a Sunday low of $80,595 and briefly crossed $83,000 before sliding back below $82,000. Analysts noted that BTC remained trapped in a tight $82,000-$83,000 consolidation zone, with the $81,144 level identified as the critical support line. A break below that threshold would put $80,000 in play as the next test.

Ether ETFs moved in the opposite direction, shedding $103.3 million on the same day, adding to a pattern of continued outflows from alternative crypto funds. Solana funds also bled assets, underscoring what analysts described as a narrowing of institutional appetite toward Bitcoin specifically, with BlackRock's IBIT, which now holds $66.37 billion in net assets, cementing its dominance over the broader spot crypto ETF landscape.
