U.S. spot Bitcoin ETFs recorded $526.7 million in net inflows on October 19, reversing the previous session’s withdrawals and recovering most of the category’s October deficit. The Monday inflow was the largest daily total since September 22, when the funds attracted $714.7 million.
According to Farside Investors, BlackRock’s iShares Bitcoin Trust accounted for all positive fund-level activity, recording $665.2 million in net inflows. Fidelity’s FBTC lost $83.6 million and Grayscale’s GBTC recorded $54.9 million in redemptions, while the remaining tracked products were flat. IBIT’s inflow was large enough to offset $138.5 million of withdrawals elsewhere and leave the overall category firmly positive.
The concentration is important because the $526.7 million headline does not represent broad inflows across the U.S. Bitcoin ETF complex. Only one fund recorded net creations on October 19, making the session primarily an IBIT-driven reversal rather than a synchronized increase across issuers.
October Deficit Shrinks to $88 Million
Bitcoin ETF flows had been volatile throughout October. Farside data show the funds entered October 19 with approximately $614.7 million in cumulative monthly net outflows after several sharp redemption sessions, including $484.9 million on October 7 and $261.4 million on October 14. Monday’s $526.7 million inflow reduced the month-to-date deficit to roughly $88 million.
The reversal follows an earlier stretch in which Bitcoin ETFs lost $244.1 million in their second consecutive outflow session. That period itself came shortly after a nine-day inflow streak ended with $148.7 million in redemptions, illustrating how quickly creations and redemptions have changed direction since late September. The October 19 result is therefore a large one-day reversal, not yet evidence of a sustained new inflow cycle.
SoSoValue data put total spot Bitcoin ETF trading volume at approximately $2.09 billion for the session, with IBIT accounting for about $1.76 billion. Total net assets stood at $105.46 billion, equivalent to roughly 6.4% of Bitcoin’s market capitalization, while cumulative net inflows since launch were approximately $57.40 billion. Assets under management and daily ETF flows remain separate metrics because changes in Bitcoin’s price also affect fund asset values.
Farside’s cumulative series produces a slightly different figure of approximately $57.48 billion. The difference reflects separate datasets and reporting methodologies rather than a materially different interpretation of the October 19 session.
Ethereum and Solana Funds Remain Negative
The Bitcoin rebound was not shared across the major crypto ETF categories. U.S. spot Ether ETFs recorded $103.3 million in net outflows on October 19, with BlackRock’s ETHA accounting for $95.4 million of the total. Bitcoin and Ether products therefore moved in opposite directions despite BlackRock funds dominating activity in both categories.
The divergence follows a volatile period for Ethereum funds. Ether ETFs only recently ended a 10-session redemption streak with $24.8 million in inflows, before returning to substantial withdrawals later in the week.
Solana ETFs also remained negative, posting approximately $6.72 million in net outflows on October 19. Bitwise’s BSOL accounted for about $4.88 million, while Fidelity’s FSOL lost another $1.84 million.
The October 19 data ultimately show a concentrated Bitcoin ETF rebound rather than a broad crypto-fund inflow. IBIT generated enough net creations to reverse most of Bitcoin ETFs’ monthly deficit in a single session, while Ether and Solana products continued recording redemptions. Several additional trading days will be needed to establish whether the Bitcoin move develops into another sustained creation period or remains an isolated high-volume reversal.
