Summary
US spot Bitcoin exchange-traded funds attracted $526.7 million on Oct. 19, reversing the previous week's withdrawals and marking the largest inflow in nearly two weeks, according to SoSoValue data. The inflow more than doubled the $228.4 million withdrawn during the five trading sessions ending Oct. 16. BlackRock's iShares Bitcoin Trust drove the recovery with $665.2 million in inflows, its strongest session since Oct. 7, 2025. Those purchases offset $83.6 million in outflows from Fidelity's FBTC and $54.9 million from Grayscale's GBTC, while nine other funds reported no net flows.
The rebound coincided with Bitcoin recovering toward $82,800 on Monday after briefly falling below $80,000 the prior week. Selling pressure had followed stronger-than-expected US inflation figures that revived expectations of further Federal Reserve rate increases. Demand remains volatile: Bitcoin ETFs recorded about $907 million in combined withdrawals over the preceding two weeks, including $679 million in the week ended Oct. 9. Monday's inflows offset more than half of that, leaving roughly $380 million in net withdrawals over the three-week period. Daily flows have alternated between inflows and outflows for six consecutive sessions. Cumulative net investment into Bitcoin ETFs now stands at $57.40 billion, with total assets of $105.46 billion, approximately 6.4% of Bitcoin's market capitalization.
BlackRock's inflow accounted for roughly 126% of the market's net purchases on Monday, illustrating how demand for a single product can outweigh selling across competing funds. The concentration contrasts with Ethereum ETFs, which lost another $103.3 million on Oct. 19. BlackRock's Ethereum ETF (ETHA) accounted for $95.4 million of those withdrawals. The outflow extended a withdrawal streak that has erased more than $1.1 billion over the past 15 trading sessions; the only positive session in that span brought in $24.8 million on Oct. 13. Cumulative net inflows into Ethereum ETFs have fallen from nearly $14 billion to $12.84 billion, and total assets declined about 17%, from $17.79 billion to $14.7 billion, reflecting both redemptions and lower Ethereum prices.
Net, Bitcoin ETFs outperformed Ethereum products by approximately $630 million in a single session, according to the flow data, a gap the source attributes to investors reassessing their cryptocurrency allocations.
