Bitcoin spot ETFs pulled in $698.42 million in net inflows over the seven days through Sept 8, extending a steady accumulation pattern. On the day itself, BTC products added another $31.07 million.
Ethereum ETFs moved in the opposite direction in the same session, bleeding $48.34 million, though ETH's seven-day tally stayed marginally positive at $39.18 million.
Why it matters
The split is the real signal. BTC's $31M daily inflow landed opposite a $48M ETH outflow, a divergence that points to where institutional conviction is consolidating this cycle. ETH's weekly net remains positive, but daily direction flipped hard, and flows follow conviction faster than they follow narrative.
Market impact
A $698M weekly haul for spot BTC ETFs is a meaningful tape-read: that level of bid absorbs several days of miner sell pressure and confirms continued institutional appetite at current prices. ETH's single-day $48M outflow is not catastrophic in context, but the asymmetry, where BTC adds while ETH bleeds, is the kind of rotation that tends to persist once it starts. Watch tomorrow's print: a follow-up ETH outflow would confirm the rotation, a snapback would suggest it was noise.
