U.S. spot Bitcoin exchange-traded funds turned negative on Aug. 28, breaking a nine-day inflow streak, while spot Ethereum funds kept drawing fresh money.
Bitcoin ETFs post net outflows on Aug. 28
U.S. spot Bitcoin ETFs recorded $201.9 million in net outflows on Aug. 28, according to SoSoValue, ending a run of consecutive inflows that had lasted since mid-August. The shift reduced cumulative net inflows to about $55.1 billion, while total net assets stood at roughly $93.9 billion.
Decrypt’s ETF flow tracker flipped its Bitcoin sentiment reading to “bearish” for the day.
An ETF, or exchange-traded fund, is an investment product that holds an underlying asset and trades on a traditional stock exchange. Investors buy and sell shares through a regular brokerage account. A spot Bitcoin ETF holds actual Bitcoin, and each share represents a claim on part of that pool, giving investors price exposure without having to buy and custody the asset directly.
That ease of access is one reason the products have appealed to traditional and institutional investors. U.S. spot Bitcoin ETFs launched in January 2024 after years of regulatory rejection, then quickly became some of the fastest-growing ETFs on record.
Daily fund flows now swing between sizable accumulation and sharp withdrawals along with price action and the macro backdrop. For that reason, market participants often watch ETF flows as a gauge of broader sentiment.
A strong run before the reversal
The Aug. 28 pullback followed a powerful stretch. Bitcoin ETFs brought in $2.8 billion over an eight-day streak as Bitcoin tested $80,000. Earlier in that run, the group also logged its biggest single-day intake since May.
During the streak, daily inflows repeatedly topped $300 million and peaked at more than $600 million on Aug. 20.
Ethereum ETFs extend their winning streak
Ethereum funds showed a different pattern. SoSoValue data shows U.S. spot Ethereum ETFs took in $102.1 million on Aug. 28, extending their inflow streak to 10 straight days.
That pushed cumulative net inflows to about $12.9 billion, with total net assets at roughly $13.8 billion.
Decrypt’s tracker kept its Ethereum reading “bullish.” The outlet said the steady demand marked a notable shift, as Ethereum products in recent sessions have nearly matched or rivaled Bitcoin’s daily intake despite operating with a much smaller asset base.
Split flows come as Bitcoin pulls back
The divergence came as Bitcoin weakened after hawkish remarks from Federal Reserve Chair Kevin Warsh at Jackson Hole cooled a rally that had carried the token toward $80,000. Bitcoin later recovered to around $79,000 over the weekend.
Even so, the one-day outflow remains modest compared with the tens of billions these funds have accumulated since launch. Decrypt also noted that the break in the streak does not necessarily point to a broader reversal in institutional appetite, which has remained strong across both assets.
