Bitcoin ETFs draw $368M in a day, strongest this month

All 12 spot Bitcoin ETFs posted inflows, led by Fidelity’s FBTC and ARK/21Shares’ ARKB, while Ether ETFs saw outflows again.

U.S. spot Bitcoin ETFs pulled in about $368 million on September 8, ending a two‑day run of outflows. It’s the biggest one‑day net intake in a month, according to SoSoValue.

Buying was broad‑based. None of the funds posted redemptions. Fidelity’s FBTC led with roughly $156.5 million in net subscriptions. ARK/21Shares’ ARKB followed at about $89.5 million. The rest of the lineup finished positive and made up the balance.

The timing isn’t random. Traders are lining up for a dense U.S. macro week: payroll revisions on Tuesday, PPI on Wednesday and CPI on Thursday. All three will feed into the Sept. 17 Federal Reserve rate decision. A quarter‑point cut is still the base case on most desks, but chatter about a larger move has picked up. Previously, GNcrypto reported that Standard Chartered now expects the Fed to cut rates by 0.5% next week.

Ether went the other way. U.S. Ethereum ETFs saw net outflows again, roughly $96.7 million on the day, extending a multi‑day streak. That matches what some analysts are calling a rotation. Illia Otychenko of CEX.IO put it simply:

Capital rotation patterns suggest funds are shifting back into Bitcoin from Ether.

For crypto investors, the picture is straightforward: flows have turned positive into a big data week, with leadership from the largest Bitcoin products and a temporary pullback in Ether funds.

How the week lands will set the tone: softer inflation and a dovish message keep BTC ETF demand firm; a hotter print or hawkish guidance can flip flows just as fast.
