U.S. spot Ethereum ETFs posted $320.1 million in net outflows in the trading week of October 12–16, while Bitcoin funds shed $228.4 million over the same five sessions. The $91.7 million gap is the clearest sign yet that money is leaving the two fund categories at different speeds, and it stretched Ethereum’s losing streak to a third consecutive week. The headline totals, though, hide more than they show: nearly the entire Ethereum number traces to one product.

BlackRock’s iShares Ethereum Trust, the fund that trades under the ticker ETHA, accounted for $299 million of that $320.1 million weekly outflow. That is 93.4 percent of the category total. Strip out ETHA and the rest of the Ethereum complex was close to flat. Fidelity’s FETH actually took in $10.5 million, while Grayscale’s Ethereum Trust and its Mini Trust shed $18.3 million and $12.4 million respectively. A handful of large institutional redemptions in a single vehicle moved the whole category’s weekly figure. That concentration runs both ways. The same fund that dominates the outflows would dominate any recovery, so the category’s weekly reading is, for now, effectively a single-fund story.

Bitcoin’s outflows were shallower and spread across more names. BlackRock’s IBIT lost $165.4 million and Fidelity’s FBTC $60.2 million, with the heaviest single session landing on Wednesday at $261.4 million. That one-day withdrawal exceeded Bitcoin’s entire five-day net total, a reminder of how much a single redemption day can dominate a weekly reading.

The asymmetry has a structural cause worth naming. U.S. spot Ethereum ETFs do not pass through staking rewards, while an institution that stakes ether directly earns a yield on the asset. A buyer who wants both the exposure and that return has a reason to hold the asset outside the wrapper. For an institution that can stake directly, the fund is the lower-yield way to hold the same asset, so the wrapper is the first thing trimmed when a portfolio de-risks. Bitcoin carries no native yield, so its funds face no equivalent handicap. That difference means Ethereum ETFs tend to begin each risk-off episode at a disadvantage, which helps explain why their outflows run deeper and last longer.

None of this is a verdict on the ETF structure. Both categories remain in positive territory for 2026, and net flows measure share creation and redemption rather than the market value of existing assets. A fund can post redemptions while its asset base stays large. What the week records is positioning, not a withdrawal of conviction.

The number to watch is not the weekly total but the sequence. Because the concentration cuts both ways, if BlackRock’s ETHA stops bleeding, the category’s weekly figure flips positive almost on its own. Ethereum funds recorded one positive session last week. A second would be an early sign that the de-risking is unwinding. Until then the gap is best read as a single heavily concentrated fund absorbing most of a macro-driven pullback, not a broad judgment on either asset.
