U.S. Spot Bitcoin ETFs Post $462.6M Weekly Net Outflow
AI Market Summary
U.S. spot Bitcoin ETFs flipped to net outflows ($462.6M over Sep 8–11), reversing prior week inflows near $1B and signaling softer institutional risk appetite. The drawdown coincided with higher Treasury yields and inflation surprises that pressured risk assets and refocused attention on the Sep 16 Fed decision, where markets price a likely 25 bp hike. Concentrated redemptions in ARKB/GBTC add to near-term flow-driven volatility.

U.S. spot Bitcoin ETFs swung back to net redemptions this week after solid inflows the prior week, according to CoinDesk. The shift came as U.S. Treasury yields moved higher and inflation data sparked volatility, sending bitcoin off its weekly peak and turning attention to the Federal Reserve's rate decision next week.
From Sept. 8 to Sept. 11, the group recorded a combined net outflow of $462.6 million. With the U.S. Labor Day holiday on Sept. 7, the reporting period covered one fewer trading day. Daily flows were negative throughout the week: $46.6 million on Sept. 8, $120.2 million on Sept. 9, and $282.6 million on Sept. 10, the largest single-day outflow of the week. Another $13.2 million exited on Sept. 11.
The pullback marks a sharp cooldown from the previous week, when U.S. spot Bitcoin ETFs drew nearly $1 billion in net inflows, pointing to softer near-term sentiment.
Bitcoin also retreated after its August run. As some investors took profits and yields rose, BTC fell from $81,427 to about $76,000 and was last trading near $77,343. On Sept. 10, it briefly dipped below $77,000. Reports cited inflation data coming in above expectations that day, reviving concerns the Fed could keep raising rates and weighing on risk assets. While core CPI was described as sitting at a five-year low, uncertainty over the policy path has contributed to slower ETF subscription demand.
Several major funds saw notable redemptions, with ARKB and GBTC facing the heaviest selling pressure. IBIT posted roughly $52.5 million in outflows, and FBTC about $50.7 million. A small number of products still attracted new money: Morgan Stanley's MSBT took in around $19.7 million, one of the few with net inflows.
Investors are now focused on the Fed's Sept. 16 decision. The report said markets are pricing in an 87% chance of a 25-basis-point hike. If macro pressure persists, short-term volatility in bitcoin could increase, and ETF flow trends are being watched as a real-time gauge of institutional risk appetite.
