US spot Bitcoin ETFs shed $120.2 million on September 9, the second straight day of net redemptions, while Ethereum ETFs pulled in $34.75 million the same day. Bitcoin ETFs still posted roughly $820 million in net inflows over the trailing seven days, even as the category's 2026 year-to-date total stays in outflow territory.
Bitcoin outflows concentrated in two funds
US spot Bitcoin ETFs hemorrhaged $120.2 million on September 9, marking the second straight day of net redemptions. ARK 21Shares' ARKB led the retreat with $78 million in net redemptions, while Grayscale's GBTC shed $27.2 million. The prior session, September 8, had already seen $46.6 million leave Bitcoin ETFs, bringing the two-day total to roughly $166.8 million.
That back-to-back daily outflow streak was the first of its kind since mid-August. For context, September 3 alone saw $730.9 million pour into Bitcoin ETFs, so the recent pullback erased less than a quarter of a single day's inflows from earlier in the month.
Ethereum ETFs move the other way
Ethereum ETFs told the opposite story. The $34.75 million in net inflows on September 9 came primarily from BlackRock's staking-enabled ETHB product. That single fund accounted for $22.94 million of the day's total.
Zoom out to the trailing seven days, however, and Bitcoin ETFs actually posted roughly $820 million in net inflows. One day's red ink looks a lot less alarming when the weekly ledger is still deeply green.
Year-to-date flows stay negative
Since spot Bitcoin ETFs launched in the US, they've attracted approximately $55 billion in total net inflows. Yet 2026 as a calendar year has been choppier, with roughly $1.07 billion in net outflows on the year overall. That year-to-date deficit means Bitcoin ETF investors in aggregate have been net sellers in 2026, even as individual weeks post massive inflows.
