U.S. spot Bitcoin ETFs attracted more than $1.07 billion in net inflows over three trading sessions through Wednesday, reversing October's earlier outflow trend. Ethereum ETFs, however, continued to struggle, losing approximately $1 billion during the month as investors showed diverging demand for the two largest cryptocurrencies.

The Bitcoin ETF rebound came even as Bitcoin traded around $81,904, down 1.6% over 24 hours.

BlackRock, Fidelity Lead Bitcoin ETF Rebound

U.S. spot Bitcoin ETFs recorded $526.7 million in net inflows on Monday, followed by $23.2 million on Tuesday and $524.8 million on Wednesday, bringing the three-session total to approximately $1.075 billion, according to Farside data.

BlackRock's iShares Bitcoin Trust (IBIT) led the Monday session with $665.2 million in inflows, its largest daily intake since October 2025. On October 21, IBIT attracted another $235 million, while Fidelity's Wise Origin Bitcoin Fund (FBTC) received $212.7 million, its largest daily inflow of the month.

Other funds, including Grayscale Bitcoin Mini Trust (BTC), Bitwise Bitcoin ETF (BITB) and ARK 21Shares Bitcoin ETF (ARKB), also recorded inflows on Wednesday.

The surge reversed October's earlier negative flow trend, bringing month-to-date net inflows to nearly $460 million. Whether this marks a sustained recovery will depend on whether inflows persist in subsequent sessions.

Ethereum ETFs Lose $1 Billion as ETHA Leads Outflows

Meanwhile, spot Ether ETFs recorded approximately $1.01 billion in net outflows this month through Wednesday.

BlackRock's iShares Ethereum Trust (ETHA) accounted for approximately $954 million in October outflows, nearly all the group's losses. However, Ether ETFs found slight relief of roughly $15 million in net inflows on Wednesday, ending a five-session outflow streak.

One potential difference for investors is staking. ETHA does not stake its Ether holdings to generate staking rewards, whereas direct Ether holdings can potentially earn yield through staking. Tom Lee-led Bitmine reportedly staked another 159,728 ETH during the week, according to 99 bitcoins, highlighting an alternative approach to generating returns from Ether.

The contrasting flows suggest that investors have favored Bitcoin-linked products over Ether funds during October. However, the data alone does not establish whether staking, price expectations or broader market positioning explains the divergence.

Separately, $41 Million Bitcoin Transfer Draws Attention

In a separate development, a wallet linked by blockchain analytics firm Arkham Intelligence to convicted Irish drug trafficker Clifton Collins transferred another 500 BTC, worth approximately $41 million, to a Coinbase Prime deposit address on Tuesday.

Collins reportedly accumulated 6,000 BTC in 2011 and 2012 using proceeds from drug dealing. Approximately 2,500 BTC from Collins-linked holdings have reportedly moved during 2026, leaving around 3,500 BTC in associated wallets. The latest transfer does not establish that the Bitcoin was sold or that the movement affected ETF flows.

For ETF investors, the immediate question remains whether Bitcoin's renewed fund demand can persist despite geopolitical uncertainty, while Ether funds continue to experience substantial withdrawals.
