Spot Bitcoin ETFs turned red for the first time since mid-August, losing more than $460 million over four business days last week. Ethereum ETFs moved in the opposite direction during the same stretch, pulling in fresh money as the underlying asset pushed toward an eight-month high.
The shift played out across US-listed exchange-traded funds tracking both cryptocurrencies, with data from SoSoValue showing a clear split in investor sentiment. Bitcoin’s outflows followed a strong run in August, while Ethereum extended its winning streak into a fourth straight week.
Bitcoin Funds Reverse Inflow Trend
Bitcoin ETFs recorded their best week in months between August 17 and 21, pulling in over $1.9 billion as the price jumped from under $65,000 to nearly $80,000. That momentum carried into the following two weeks too, with $924 million and $986 million in net inflows. Last week broke that pattern.
Outflows began on Tuesday at $46.65 million, followed by $120.24 million on Wednesday, $282.56 million on Thursday, and $13.29 million on Friday, the same day fresh inflation data landed. Total net inflows for Bitcoin funds slipped from $55.62 billion to $55.15 billion. Bitcoin’s price also swung sharply, dropping to $76,000 before climbing to $79,800 and settling back near its starting point.
Ethereum ETFs Maintain Strong Inflows
Ethereum ETFs followed a bumpier path early in the week, with $24.29 million leaving on Monday before $34.75 million came back in on Wednesday. Thursday saw another $29.76 million in outflows. Friday changed everything, as net inflows hit a two-week high of $216.41 million. Ethereum’s price spiked more than 8% within an hour of the inflation report, touching $2,670 before settling near $2,500.
Only one of the last ten weeks saw Ethereum ETFs post outflows, and that dip stayed small at just $2.26 million. Total net inflows for Ethereum funds climbed from under $10.89 billion to $13.39 billion over that period.
What’s Next for Crypto ETFs?
Markets now turn their attention to the CLARITY Act, which heads to the US Senate next week, along with the Federal Reserve’s upcoming rate decision, both of which could shape investor flows into crypto ETFs going forward.
