Ether ETFs Extend Their Inflow Streak to Eleven Sessions

US spot ether ETFs recorded roughly $87.68 million of net inflows in a recent session, extending a positive streak to eleven, with BlackRock's ETHA taking $59.94 million of it.

Small numbers, consistent direction

By the standards of the bitcoin complex these are modest figures. What distinguishes them is consistency. Eleven consecutive sessions of inflows into any fund category is unusual in a market where allocator behaviour has been characterised by round trips all year — and it stands in contrast to the bitcoin funds, which remain about $1 billion short of breaking even in 2026 despite a $3.52 billion August.

The upgrade in the background

The flows are arriving ahead of Glamsterdam, the largest protocol change since the Merge, which forks Sepolia around 21 September with mainnet activation expected in November. It is reasonable to assume some of the bid is positioning for it.

It is also reasonable to be sceptical of that explanation. ETF buyers are not typically trading protocol roadmaps, and the flows have been too steady and too evenly distributed to look like an event trade. A duller reading fits better: model portfolios that added ether allocations earlier in the year are now rebalancing into them on schedule.

What staking would change

The structural question for the category remains staking. Filings to add staking to US ether ETFs are in progress, and approval would alter the product materially — from an instrument that tracks a yield-bearing asset without capturing the yield, to one that captures some of it.

That is the difference between a fund that holds ether and a fund that holds ether properly, and it is the single change most likely to move these flows from steady to significant.
