BlackRock's IBIT carried the day for Bitcoin funds while Ethereum ETFs extended their outflow streak to nine straight sessions
US spot Bitcoin ETFs pulled in $21.13 million in net inflows on October 9, according to data from SoSoValue. It’s a small number, but it arrived after a rough stretch.
The day before, the same group of funds bled $244.1 million.
Ethereum funds didn’t share the relief. Spot Ether ETFs shed $56.10 million on the same day, their ninth consecutive session of net outflows.
Who did the heavy lifting
BlackRock’s iShares Bitcoin Trust, ticker IBIT, did most of the work. It took in $22.38 million on its own, which is more than the entire category’s net figure.
VanEck’s HODL added $2.33 million.
Fidelity’s FBTC went the other direction, with $3.58 million in net withdrawals. The remaining products posted no net change for the day.
The bigger picture is still red
Over the past five trading days, spot Bitcoin ETFs have recorded cumulative net outflows of approximately $679 million.

Since the products launched in January 2024, cumulative net inflows have reached roughly $57.11 billion.
Total assets under management across the US spot Bitcoin ETFs now sit at around $105.84 billion. The cumulative inflow figure stands at about 6.38% of Bitcoin’s total market capitalization.
Ethereum’s losing streak keeps going
The Ether side of the ledger tells a gloomier story. The $56.10 million outflow on October 9 marked the ninth straight day of net redemptions for spot Ethereum ETFs.
BlackRock’s ETHA accounted for a considerable share of that withdrawal. That’s an interesting split: the same issuer was the top buyer on the Bitcoin side and a major source of selling on the Ether side.
Major issuers in the space include BlackRock with IBIT and ETHA, Fidelity with FBTC and FETH, VanEck with HODL, and Grayscale with GBTC and ETHE.
Why daily flow data gets so much attention
Spot ETFs hold the underlying asset directly. When money comes in, the fund generally needs to own more of the coin; when money leaves, it needs less.
That mechanical link is why trackers like SoSoValue and Farside Investors publish flow figures daily. Institutions watch the numbers as a rough read on how professional money feels about Bitcoin and Ether.
What this means for investors
The concentration is worth noting. With IBIT supplying more than the net total by itself, the inflow depended heavily on a single product.
The split between the two assets is the most telling detail of the day. Investors aren’t abandoning crypto ETFs wholesale; on October 9, they were selectively adding to Bitcoin while trimming Ether.
