Strip ETHA's $1.02 billion out and every other US spot Ethereum product combined took about $400 million across the nine sessions [1], which works out to roughly $44 million a session for the entire rest of the shelf against ETHA's $113 million [2] [3]. That is the shape of the month. On the best single day of the run, Fidelity's FETH at $56.2 million and BlackRock's staked ETHB at $20.7 million together accounted for 34% of the $225.8 million total [8], and that was the non-flagship shelf's high-water mark, not its average.
Set the streak against standing assets and the concentration gets more interesting: $1.42 billion arriving in nine trading days is about 11% of the $12 billion to $13 billion of combined assets the category has gathered since July 2024 [4] [12]. Or rather, the more interesting version of that comparison is ETHA's own cumulative inflow, which has passed $12 billion since launch [11] and therefore roughly equals the market value of the whole shelf [10], a sentence about ETH's price path as much as about anybody's conviction.
The counter-thesis is on the record and it is a decent one. Max Shannon of Bitwise Europe says the buying is coming from outside crypto, put this week's take at $713.6 million (half the entire streak [7]) and attributed it to a marked rise in the firm's Cross Asset Risk Appetite measure [14], which is a story about generalist money reaching for a wrapper rather than about anyone's sales force. Both can be true. Generalist money still has to arrive through somebody's distribution, and here it arrived through one fund that did not miss a single session [4].
The reporting is looser than the numbers deserve. Cryptobriefing described the run as a nine-to-ten session streak [19] where Farside's data gives nine [2], and carried a mid-month figure of over $534 million that it called a single-day or short-window surge [18], which cannot be a single day when $225.8 million was the strongest since October 2025 [9]. Arkham's count of $889.8 million over the first eight days, matching Farside exactly [5], is the more useful item, because it means two independent tallies agree on the concentration.
This is probably wrong, but I read the $16.5 million gap with Bitcoin ETFs [8], narrowed from a ten-to-one deficit on August 17 to 93% of Bitcoin's take by the 27th [6], as a fact about one order book rather than a fact about ETH, which was changing hands near $2,477 on Friday while lagging Bitcoin and the larger altcoins over the same stretch [10] [15]. What would change my mind is a September that keeps the total and loses the share: if the streak extends while ETHA drops toward half of category flow, then August was demand broadening and I mistook the plumbing for the water.
