US spot Bitcoin exchange-traded funds (ETFs) saw a significant rebound on Monday, October 19, 2026, with $526.7 million in net inflows. This marked their largest daily intake in nearly a month, reversing the $82.4 million in net outflows recorded on Friday. According to Farside Investors, the last time these funds saw such strong inflows was on September 22, when they attracted $714.7 million.
BlackRock’s iShares Bitcoin Trust (IBIT) led the gains with $665.2 million in inflows, surpassing the net total across all funds. However, these gains were partially offset by $83.6 million in withdrawals from Fidelity’s Wise Origin Bitcoin Fund (FBTC) and $54.9 million from Grayscale Bitcoin Trust (GBTC). Other funds recorded no net flows, according to Farside.
The rebound followed two weeks of net outflows on a weekly basis. Last week, spot Bitcoin ETFs shed about $229 million after losing $681 million the week before. The funds also recorded $483.9 million in outflows on October 7, their largest daily withdrawal since June. Despite Monday’s inflows, US spot Bitcoin ETFs remain about $88 million in negative territory for October.
Meanwhile, US spot Ether ETFs recorded $103.3 million in net outflows on Monday, led by $95.4 million in withdrawals from BlackRock’s iShares Ethereum Trust (ETHA). Ether funds lost about $320 million last week, marking their third consecutive week of net withdrawals.
