U.S. spot Bitcoin exchange-traded funds recorded their largest weekly inflow since October with $2.4 billion in net additions, reversing the year-to-date flow trajectory and moving cumulative 2026 net flows into positive territory. The week prior had seen Ethereum ETFs shed $140 million; that reversal flipped to $690 million in inflows for ether-tracking funds.
The inflow surge marks a sharp shift in institutional appetite after a period of outflows earlier in 2026. Bitcoin ETF net flows had been negative through much of the year until this latest week. The timing and size of the capital movement suggest renewed demand across both Bitcoin and Ethereum spot products.
It remains unclear what drove the concentrated inflows in that specific week, whether flows will sustain at similar levels going forward, or how the reversal of prior Ethereum outflows correlates to broader market conditions or product-specific factors.
