Bitcoin ETFs Pull $170M as Ether Counterparts Bleed $11M in Single Session

The past week saw a stark contrast in investor sentiment towards Bitcoin and Ether ETFs. On Monday, spot Bitcoin ETFs pulled in $170 million in net inflows, while their Ether counterparts shed $11.4 million on the same day.

This divergence is not an isolated incident. According to flow data from trackers like SoSoValue and Farside Investors, Bitcoin ETFs have been consistently preferred by institutional investors over Ether ETFs. In fact, an $11.4 million outflow for Ether is not catastrophic in isolation but part of a broader pattern of inconsistency for Ether ETF products.

The major issuers in this space, BlackRock with its IBIT and ETHA products, Fidelity with FBTC and FETH, and Grayscale with its suite of converted and new products, all compete for the same pool of institutional dollars. When the Bitcoin products absorb inflows while the Ether products shed assets, it is a clear indication of investor preference being expressed through capital movement.

US spot Bitcoin ETFs launched in January 2024, after years of SEC rejections. Spot Ether ETFs followed later in 2024. Collectively, both asset classes accumulated cumulative flows reaching tens of billions before conditions shifted heading into 2025 and 2026. What makes Monday's $170 million figure notable is the contrast with Ether's simultaneous outflow, reinforcing a pattern that has been building for several months.
