Bitcoin ETFs Log Second Straight Week of Outflows While Ether ETFs Shine With Fourth Successive Week of Inflows

A tale of two crypto markets unfolded this past week. While bitcoin ETFs continued their downward slip with a $128.81 million net outflow, ether ETFs surged ahead, notching their third-highest weekly inflow of 2025 at $281.07 million. The divergence marks the second straight week of bitcoin ETF weakness, starkly contrasting ether’s growing investor appetite.

Thursday, June 5, delivered the week’s worst session for bitcoin ETFs, with outflows totaling $278.44 million, dragging the overall weekly figure into the red despite two positive days.

Blackrock’s IBIT was the lone bright spot, ending the week with an $81 million net inflow. On the flip side, Fidelity’s FBTC bled $167.72 million, topping the outflow chart, while Grayscale’s GBTC and Ark 21shares’ ARKB shed $40.57 million and $24.54 million, respectively. Vaneck’s HODL and Bitwise’s BITB offered some relief, adding $19.66 million and $12.94 million, but not enough to change the week’s bearish tilt.

For ether ETFs, Blackrock’s ETHA stole the show with $249.15 million in weekly net inflows, fueling the asset class’s stellar performance. Grayscale’s Ether Mini Trust and Fidelity’s FETH followed with inflows of $9.37 million and $3.73 million. No ether ETF posted a net outflow, reflecting broad market confidence.

Total net assets stood firm, with bitcoin ETFs closing at $125.58 billion and ether ETFs holding near $9.40 billion. The contrast in flows suggests growing institutional interest in ether over bitcoin for the week.
