US spot Bitcoin ETFs recorded $462.7 million in net outflows during the four trading sessions from Sept. 8 to Sept. 11. Ethereum ETFs moved in the opposite direction, bringing in $196.9 million, while Solana funds recorded a smaller $9.7 million inflow.
Bitcoin ETFs saw net outflows in every session during the week. The losses started at $46.6 million on Tuesday, increased to $120.2 million on Wednesday, and reached $282.7 million on Thursday. The outflow then slowed to $13.2 million on Friday.
The four sessions erased part of the $986.7 million in inflows Bitcoin ETFs recorded during the previous trading week.

Some Bitcoin ETFs still attracted money. Morgan Stanley’s MSBT recorded $19.7 million in inflows across the four sessions, with positive flows each day. Bitwise’s BITB gained $1.9 million for the week.
Ethereum ETFs had a much stronger week. The funds were down $19.5 million heading into Friday, but a large $216.4 million inflow on Friday pushed the weekly total to a $196.9 million gain.
