Monday's session gave US spot bitcoin funds their largest daily net inflow in nearly a month, with $526.6M added in total. The last bigger day came on September 22, when the group took in $714.7M.

BlackRock's IBIT alone pulled in $665.2M, its biggest daily inflow since October 7, 2025, more than the entire group's net total.

Fidelity's FBTC lost $83.6M and Grayscale's GBTC shed $54.9M, while the remaining funds recorded no net flows. The day more than erased last week's $228.5M of withdrawals, though bitcoin ETFs are still about $90.5M in the red for October.

Ether funds moved the other way, losing $103.3M in a fourth straight session of outflows. BlackRock's ETHA accounted for $95.4M of those withdrawals.
