Bitcoin ETFs vs Ethereum ETFs: Which Bled More Last Week?

Why Size Makes the Comparison Tricky

The U.S. spot Bitcoin ETF market is substantially larger than its Ethereum counterpart in terms of cumulative assets under management. That means a given dollar outflow represents a far larger percentage swing for Ethereum ETFs than for Bitcoin ETFs. Readers tracking weekly headlines should watch both the raw dollar total and the percentage of AUM being redeemed, since a smaller Ethereum ETF market can show outsized percentage moves even when the absolute dollar figure looks modest against Bitcoin.

Ethereum ETFs have already shown signs of structural selling pressure, with ETH trading below its 50-day moving average alongside elevated redemption activity, compressing both the spot price and fund-level demand simultaneously. When spot prices weaken, authorized participants face less arbitrage incentive to create new shares, which can amplify net outflow readings even without a dramatic surge in redemptions.

Bitcoin ETFs Are Not Immune to Outflow Weeks

Bitcoin ETFs carry a much larger base but have also logged sharp single-week withdrawal episodes. Bitcoin ETFs recorded severe withdrawals following a sudden price correction, illustrating that even the most liquid crypto fund category can flip from inflow to outflow mode quickly when spot prices break a key level. In those episodes, a small number of sessions typically account for the bulk of the weekly net outflow, rather than steady daily redemptions.

Macro catalysts accelerate both sides of the trade. Bitcoin, Ethereum, XRP, and Dogecoin all dipped ahead of Fed minutes, a reminder that ETF flows often track broader risk-off moves rather than crypto-specific narratives. When equities sell off on rate expectations, crypto ETF holders who treat the products as risk-asset exposure tend to reduce positions, affecting Bitcoin and Ethereum funds in parallel.

What to Watch to Answer the Question Definitively

The most reliable way to settle which category bled more in any given week is to check daily net flow aggregates from sources such as CoinGecko’s Bitcoin market page and equivalent Ethereum data alongside fund-level disclosures from issuers. Aggregate weekly net flow, divided by the category’s total AUM at the start of the week, gives the cleanest apples-to-apples percentage comparison.

For context on where flows stand relative to the longer arc of institutional demand, the cumulative net inflow figure matters more than any single week. A category that has absorbed billions in net inflows since launch can absorb a difficult outflow week without signaling a structural reversal. Conversely, Ethereum ETFs, which launched later and have a shorter track record, carry less of a cumulative cushion, making each negative week proportionally more visible. XRP ETFs extending a 13-week inflow streak with $11.31 million in fresh demand shows how newer crypto fund products can diverge sharply from the Bitcoin and Ethereum trend in any given period, further complicating any single-asset narrative about “crypto ETF flows.”

Until verified weekly aggregate data for both categories is available from official filings or tracked fund disclosures, the honest answer is that the relative bleed depends on which lens you apply: raw dollars favor Bitcoin ETFs producing larger absolute outflow figures in a down week, while percentage-of-AUM measures often tilt toward Ethereum. Both metrics matter, and neither alone tells the full story.
