Spot Bitcoin ETF outflows reached about $120 million on September 9, the second day running that cash left the funds. On that same session, every other crypto ETF category pulled money in. Ethereum products took in roughly $35 million. XRP funds added about $12 million, and Solana funds gathered a similar figure. Bitcoin traded near $78,000 as it happened, then slipped under $77,000 the following day and printed a session low around $76,750.
Most desks led with the price. Bitcoin below $77,000, oil back over $100, Treasury yields climbing. All of that is real. The flow numbers point somewhere the price chart does not, because the money that left Bitcoin funds mostly stayed inside crypto rather than leaving it.
Where the money actually went on September 9
The Bitcoin damage was not spread evenly. One issuer did most of it.
| Fund | Net flow, September 9 |
|---|---|
| ARK 21Shares (ARKB) | -$78 million |
| Grayscale (GBTC) | -$27 million |
| BlackRock (IBIT) | -$20 million |
| Morgan Stanley (MSBT) | +$4 million |
| Ethereum ETFs | +$35 million |
| XRP ETFs | +$12 million |
| Solana ETFs | +$12 million |
ARK's fund carried about two thirds of the day's Bitcoin withdrawals on its own. BlackRock's IBIT, the largest of the group, gave back a comparatively small $20 million. Morgan Stanley's bank-issued fund even booked a small inflow. So this was not a broad exit from Bitcoin exposure. It read more like a rotation, with capital shifting toward Ethereum and the newer Solana funds that opened to thin demand earlier in the summer.
Early September looked nothing like this. Bitcoin ETFs had drawn more than $1 billion across three sessions the prior week, and September 3 alone brought in $731 million, their strongest single day since January. Two red sessions do not erase that. They do mark the point where the same funds that led August began to lag the field, echoing an earlier stretch when Ethereum products outpaced Bitcoin on flows.
What sat behind the two red days
The macro backdrop turned hostile in a hurry. WTI crude topped $100 a barrel for the first time since May, Brent pushed above $106, and the 10-year Treasury yield rose to 4.96% while the 30-year reached 5.362%. Rising yields pull cash toward bonds and away from assets that pay nothing, and traders using borrowed money felt it first, with $562 million in long positions wiped out on a hot inflation print. That macro squeeze explains part of the Bitcoin ETF outflows, but not why altcoin funds gained on the same day. Some of those inflows trace to plumbing rather than conviction, helped by a new SEC rule letting crypto ETFs hold a slice of ineligible assets. Whether the rotation outlasts the Bitcoin ETF outflows depends on the next inflation reading, which lands with oil and yields already doing the selling.
