HedgeCo.Net — U.S. spot bitcoin ETFs recorded a combined net outflow of $236.5 million on September 1, reversing the prior session’s $216.7 million net inflow. Farside Investors is the primary flow table. Lookonchain independently printed the same FarsideUK total of $236.5 million and the same issuer split: BlackRock’s IBIT at a $201.2 million net outflow, Fidelity’s FBTC at a $43.7 million net outflow, and Bitwise’s BITB at an $8.4 million net inflow, with other BTC products at zero net flow for the day.
Bloomingbit’s Trader T print rounded the session to $236.47 million of net outflows and confirmed the one-day reversal from August 31’s $216.7 million inflow already published on HedgeCo.Net’s Tuesday slate. IBIT again dominated the tape on the sell side; BITB was the only major product to print a positive day. The session is a single trading day—do not annualize it, and do not stack ether ETF flows into the same short.
This is a one-day flow print, not a structural redemption cycle and not a fund liquidation. Mark $236.5 million net, IBIT $201.2 million, FBTC $43.7 million, and BITB +$8.4 million as the Farside/Lookonchain figures. Do not invent AUM levels or cumulative-since-launch totals that are not in these two sources. The allocator object is the daily U.S. spot bitcoin ETF complex flipping from a strong Monday inflow to a Tuesday outflow led by the two largest issuers.
