Bitcoin ETFs see $91M in outflows as Ethereum ETFs quietly absorb $82M

For every dollar leaving Bitcoin ETFs right now, Ethereum funds are catching roughly 90 cents of it. That’s an oversimplification, but the optics tell a story that’s hard to ignore.

On June 8, US spot Bitcoin ETFs recorded net outflows of $91.37 million, according to SoSoValue data. On the same day, US spot Ethereum ETFs pulled in $82.37 million in net inflows. The near-mirror image of those numbers is striking, even if the two markets operate on very different scales.

Bitcoin’s bleeding streak continues

This isn’t a one-day blip for Bitcoin. The $91.37 million outflow is part of a much larger pattern that stretches back to mid-May, during which Bitcoin ETFs have hemorrhaged roughly $4.4 billion to $5 billion in cumulative net outflows. That’s a meaningful chunk of capital exiting products that currently manage approximately $93.7 billion in total assets.

To put that in perspective, the outflow streak has drained somewhere between 4.7% and 5.3% of total Bitcoin ETF assets in just a few weeks.

The major products caught in this downdraft include the usual suspects. BlackRock’s IBIT and Fidelity’s FBTC remain the dominant Bitcoin ETF offerings, and their sheer size means they absorb most of the flow volatility, both positive and negative.

Ethereum’s quiet comeback

The Ethereum side of the ledger looks meaningfully different. The $82.37 million inflow on June 8 came on the heels of Ethereum ETFs snapping a 17-day outflow streak.

Ethereum ETFs manage roughly $21.5 billion in assets, making them about a quarter the size of their Bitcoin counterparts. That smaller base means the $82.37 million inflow carries proportionally more weight, representing a larger percentage of total AUM.

Products tracking Ethereum, including offerings like ETHA and ETHB, are the primary beneficiaries of this renewed interest.

What this means for investors

Right now, the marginal dollar is leaving Bitcoin and finding a home in Ethereum. The sustained nature of these outflows, north of $4 billion since mid-May, suggests this isn’t just portfolio rebalancing.

The near-equal and opposite flows on June 8 support the idea that capital is moving from one digital asset to another, not heading for the exits.

For Ethereum watchers, the risk is that this inflow proves to be a head fake. Ending a 17-day outflow streak with one positive session is encouraging, but it’s not a trend yet.

One factor worth monitoring closely is how BlackRock and Fidelity position their respective products across both assets. These firms manage the largest ETFs on both the Bitcoin and Ethereum side, giving them unique visibility into where their client base is allocating.
