The institutional bid did not leave with Friday’s bitcoin outflow. It just spread out.

U.S. spot crypto ETFs took in about $2.07 billion in the week of August 24–28. Bitcoin funds led with $924.48 million. Ethereum products followed with $824.42 million. Solana, XRP, and Hyperliquid funds added another $321.22 million combined. That is a second straight week of billion-dollar-plus creations, after the August 17–21 stretch that poured $2.6 billion into bitcoin and ether alone. Daily prints were mixed. The weekly tape was not.

Bitcoin still first — with an asterisk

Bitcoin ETFs opened the week hot and closed it cold.

Monday through Thursday brought $337.56 million, $314.37 million, $232.12 million, and $242.24 million. Combined assets pushed back above $100 billion during that run. Friday reversed it: $201.81 million left, ending a nine-session, roughly $3 billion inflow streak and leaving the week at $924.48 million. That is still a strong print. It is also a reminder that bitcoin ETF demand can flip in a session when the Fed chair talks inflation and $81,000 fails.

BlackRock’s IBIT did more than its share. It took in $938.3 million on the week — more than the entire category’s net — because several rivals leaked. Grayscale’s Bitcoin Mini Trust added $81.9 million, Fidelity’s FBTC $62 million, and Morgan Stanley’s MSBT $25.3 million. IBIT remains the conversion engine. When it is buying, the complex looks healthy even if ARK and Bitwise are redeeming. When Friday hits, the headline becomes the streak that broke, not the $924 million that survived.

Two-week bitcoin ETF inflows were still about $2.8 billion. August as a whole remains one of the strongest inflow months of 2026, even after the Jackson Hole pause.

Ethereum closed the gap

Ether funds were the cleaner story.

They took in money every session: $115.57 million, $179.80 million, $192.35 million, $234.51 million, and $102 million on Friday — the same day bitcoin ETFs went red. The weekly total, $824.42 million, was ether’s strongest week since October 2025 and a 2026 high. BlackRock’s ETHA did the heavy lifting, on the order of $567 million. The category’s inflow streak stretched to 10 sessions and more than $1.4–$1.5 billion since mid-August. Assets under management sat near $15 billion, with cumulative net inflows approaching $13 billion since launch.

That is the narrowing the market has been watching. The week prior, bitcoin took $1.92 billion and ether $697 million. This week the split was $924 million to $824 million. Ether is no longer a rounding error on the bitcoin ETF tape. It is a second institutional sleeve, and it held together on the day Warsh spoke.

The rest of the shelf showed up

Altcoin products stopped being footnotes.

Solana ETFs attracted $153.87 million, more than five times the prior week’s $28.34 million and the category’s second-best week since the October 2025 launches. That burst landed in the same window Bitwise’s BSOL crossed $1 billion in assets. XRP funds took in $110.49 million, a 2026 weekly record, lifting cumulative net inflows past $1.6 billion. Hyperliquid products jumped to $56.86 million from $3.89 million the week before, with five green sessions. Smaller prints hit LINK, HBAR, and DOGE. Breadth is still a fraction of the two majors. It is no longer zero.

Friday underlined the rotation. While bitcoin ETFs lost $202 million, ether, XRP, and Solana products were reported as net positive — about $145 million combined in one tally. That is not proof of a clean handoff. It is proof that the crypto ETF complex is no longer a single-ticker market.

What $2 billion a week actually says

It says the August rally had a sponsored bid underneath the squeeze.

The week of August 17–21 was the breakout: $1.92 billion into bitcoin, $697 million into ether, volumes more than tripling, bitcoin ETF assets jumping to $96 billion on a mix of creations and a 25% price spike. The week of August 24–28 was the follow-through — smaller bitcoin number, larger ether number, first real altcoin ETF week, and a Friday stress test that bitcoin failed and ether passed. Bank of America’s broader “Flow Show” had already flagged a swing from $392 million of crypto-fund outflows to $3.2 billion of inflows around the mid-August impulse. The ETF channel is where that impulse is still visible.

The constraints are the same as last week. Creations are not the same as price. AUM can swell because coins already in the funds rallied. One issuer can mask outflows at the others. A hawkish Fed reprint can turn a nine-day streak into a one-day redemption. Year-to-date bitcoin ETF flows are still digging out of an earlier deficit. September jobs data and the September 16 FOMC meeting will decide whether $2 billion weeks are a new baseline or the tail of an August liquidity burst.

For now the scoreboard is institutional, not tactical. Two consecutive weeks above $2 billion. Bitcoin still first. Ethereum close enough to matter. Solana and XRP no longer invisible. Friday mixed the daily tape. It did not erase the week.
