Two hundred and two million dollars left the spot Bitcoin ETFs on August 28. That withdrawal snapped a nine-day inflow streak worth about $3.04 billion, and every outlet led with it. What almost none of them set next to it: the same session, the Ethereum ETFs took in $102 million and logged their tenth straight positive day. The money did not leave crypto so much as rotate inside it.
Read that way, the day tells a different story than the headline did. Ethereum ETF inflows are now on a longer unbroken run than the Bitcoin streak that just ended.
One fund drove most of the Bitcoin outflow
The $201.9 million net figure hides how lopsided August 28 was. ARK 21Shares ARKB shed $114.9 million by itself, more than the whole category's net for the day. Bitwise BITB lost $49.7 million, BlackRock IBIT $33.4 million, VanEck HODL $13.2 million. Only Morgan Stanley's MSBT finished green, at $9.3 million.
| Fund | Net flow, August 28 |
|---|---|
| ARK 21Shares ARKB | -$114.9M |
| Bitwise BITB | -$49.7M |
| BlackRock IBIT | -$33.4M |
| VanEck HODL | -$13.2M |
| Morgan Stanley MSBT | +$9.3M |
When one fund's outflow tops the category's entire net, that looks less like a broad exit and more like a single large holder stepping back. It happened on a rough tape. Bitcoin opened above $80,000 and fell 2.9% to around $77,500, with an intraday low near $77,078 after a weekly high of $81,200.
BlackRock had been the engine on the way up, too. IBIT alone took $277.6 million on August 27, and on August 24 it drew $209 million of the category's $338 million. Flows this size, in both directions, have been running through a handful of desks rather than the broad base the ETF wrapper was supposed to bring. That concentration cuts both ways, and it can turn one rebalance into a headline outflow, as it just did.
Ethereum's run is now the longer of the two
The Ethereum ETF streak reached day ten on the 28th, one session past the Bitcoin run that had just broken. The lead was building before the split. Back on August 13, the Ethereum ETFs had already outdrawn Bitcoin's on a single day, an early hint that flow leadership was shifting toward ether. You can read that earlier turn in our coverage of the day Ethereum ETFs beat Bitcoin.
The rotation showed up across assets, not just between the two majors. On August 27, the last day both sides were positive, Bitcoin ETFs pulled $242.3 million, Ethereum $235 million, Solana products $60.91 million, and the newer Hyperliquid funds $24.42 million. Solana's number stood out given how thin the first weeks after its launch had been, a gap we traced in the early Solana ETF flows.
The macro tape the flows are answering
None of this sits in a vacuum. Days earlier, crypto liquidations hit $488 million after Fed Chair Kevin Warsh pushed back on rate-cut bets, pointing to inflation running at 3.7% over twelve months, a jolt we covered in the $488 million liquidation wipeout. Bitcoin took the harder hit from that repricing. Ethereum, for now, is where the steady bid has parked.
The week's math still leaned positive. Even with the August 28 reversal, Bitcoin ETFs booked $924.5 million for the five days, and combined Bitcoin and Ethereum ETF inflows came near $2.3 billion, the biggest weekly total since October. Total assets in the spot Bitcoin funds sit around $79 billion, on roughly $8.23 billion of daily trading volume. What the flows leave open is whether the 28th was one desk trimming a position or the first day of a real handoff to ether, and the daily prints over the coming week are what will settle it.
