US Bitcoin ETFs recorded $462.7 million in net outflows across 8-11 September, while Ether funds attracted $196.9 million. The comparison sums the four sessions in Farside Investors' Bitcoin and Ether tables.
The paths differed. Bitcoin funds had net withdrawals in every session. Ether funds finished ahead because Friday's $216.4 million inflow exceeded the combined $19.5 million outflow over the preceding three sessions.
Four sessions, two directions
| Session | Bitcoin ETFs, $m | Ether ETFs, $m |
|---|---|---|
| 8 September | -46.6 | -24.3 |
| 9 September | -120.2 | +34.7 |
| 10 September | -282.7 | -29.9 |
| 11 September | -13.2 | +216.4 |
| Period total | -462.7 | +196.9 |
Positive values indicate net inflows; negative values indicate net outflows. Totals are calculated from Farside's daily figures in millions of US dollars.
The aggregate Bitcoin result also masks differences between funds. MSBT received $19.7 million across the four sessions, despite withdrawals for the category overall.
These figures measure net fund flows, not trading volume or changes in token prices. They show different demand across the two ETF groups during this period. They do not identify investors or establish that money withdrawn from Bitcoin funds moved into Ether funds. The comparison excludes the incomplete 14 September session.
