BlackRock’s IBIT raked in $665.16 million on Monday, Oct. 19, topping the total of all U.S. spot Bitcoin ETFs, which collected $526.6 million.
Bitcoin traded in a tight range around $82,000 to $83,000.

Fidelity’s FBTC fell $83.63 million, while Grayscale’s GBTC was down $54.93 million. Those two exits left the group about $139 million short of IBIT’s own intake.

IBIT recorded its biggest one-day jump since Oct. 7, 2025, and the biggest of 2026. The fund holds net assets of $66.37 billion, the most of any spot Bitcoin ETF, and took in ~8,130 BTC.
Total traded value across all funds stood at $2.09 billion. Net assets finished the day at $105.46 billion and total net inflows since launch in January 2024 are $57.40 billion.
The group lost around $229 million the week before; about $165 million of that was from IBIT. Monday killed them both in one session.
Bitcoin stayed boxed in as fears of further interest rate hikes hit risk assets. <a href="https://www.cryptopolitan.com/bitcoin-etfs-october-negative-487m-outflow/" rel="noopener noreferrer nofollow">Cryptopolitan</a> reported in October that the funds had turned the month negative after a $487 million outflow, with IBIT losing $207.7 million that day.
The group’s last bigger day was Sept. 22, at $714.75 million. But IBIT only got $381.4 million of the ~$1 billion <a href="https://www.cryptopolitan.com/bitcoin-ether-etfs-largest-inflow-october/" rel="noopener noreferrer nofollow">haul</a> a day earlier.
<h3 id="span-style-font-weight-400-ether-funds-lose-103-28-million-on-a-fourth-straight-outflow-day-span">Ether funds lose $103.28 million on a fourth straight outflow day</h3>
Ether ETFs saw a fourth straight day of outflows totaling $103.28 million. BlackRock’s ETHA accounted for $95.40 million.
Fidelity’s FETH declined $5.96 million, while Grayscale’s ETHE fell $1.92 million. Assets in ether funds dropped to $14.77 billion, after $320 million in outflows the prior week.
Solana funds were down for the 11th day in a row, with a net outflow of $6.72 million. The run comes after two consecutive record outflow weeks for Solana ETFs.
Fidelity’s FSOL was down $1.84 million, and Bitwise’s BSOL was down $4.88 million, leaving the assets at $1.63 billion.
Grayscale’s ZCSH Zcash fund lost $10.45 million, leaving it with $601.70 million in assets. Bitwise’s Near ETF (NRR) went the other way, adding $5.42 million and lifting assets to $86.95 million.
Min Jung, associate researcher at Presto Research, said it is unclear why IBIT is buying. Bitcoin has traded in a range while other risk assets are near all-time highs, which could be leading investors to establish a “catch-up trade,” Jung said.
Jung expects volatility to persist while the Federal Reserve’s rate decision remains uncertain. A clean breakout above the current range would need macro clarity and better risk appetite, Jung added.
The flows suggest institutional demand is holding up, with ETF buying mopped up by sellers at resistance, said Dominick John, an analyst at Zeus Research.
Market commentator Luke Martin noted that the last IBIT inflow of this size was ahead of Bitcoin’s strong run in August.
On Monday, BlackRock also filed for the iShares Bitcoin Managed Protection ETF, ticker PBIT, an actively managed options fund based on IBIT that caps the upside for some downside protection.
