U.S. spot Bitcoin ETFs returned to negative flows on September 8, recording approximately $46.65 million in net outflows and ending a three-session inflow streak. The reversal shows that demand for Bitcoin investment products cooled after several consecutive positive trading days, although the size of the withdrawal remained relatively modest compared with some recent swings.
The September 8 data showed a broader divergence across crypto investment products. Bitcoin, Ether and Solana funds all lost capital, while XRP ETFs attracted approximately $1.55 million. Ether products recorded $24.29 million in net outflows, according to SoSoValue data also detailed in Yahoo Finance’s review of the session.
Bitcoin ETFs Break Three-Day Inflow Run
Bitcoin’s overall withdrawal masked positive activity in several individual funds. Bitwise’s BITB attracted approximately $14.47 million, while BlackRock’s IBIT added about $10.66 million. Grayscale’s GBTC was the main source of selling pressure, posting roughly $65.51 million in net outflows, enough to push the broader Bitcoin ETF category into negative territory.
The session ended a short recovery that had included $101.1 million in Bitcoin ETF inflows on September 2, $730.8 million on September 3 and another $174.6 million on September 4. The September 8 reversal illustrates how quickly daily ETF demand can change even after several strong allocation sessions.
Ether funds showed similar fragmentation. Fidelity’s FETH attracted approximately $9.89 million despite the category finishing with $24.29 million in net redemptions. Positive demand for FETH was outweighed by withdrawals elsewhere, particularly from Grayscale products, leaving the overall Ether ETF market in the red.
XRP Bucks the Broader ETF Trend
Solana-linked ETFs also experienced withdrawals, losing approximately $667,720 during the session. XRP products moved in the opposite direction, bringing in roughly $1.55 million. XRP was the only one of the four major crypto ETF categories to record positive net flows on September 8, providing a small counterpoint to the broader withdrawal trend.
The divergence does not necessarily indicate a lasting rotation toward XRP. Daily ETF movements can reflect portfolio rebalancing, market making, arbitrage and tactical allocation decisions alongside longer-term investment demand. One positive XRP session and simultaneous Bitcoin and Ether withdrawals are therefore better treated as a daily positioning snapshot than proof of a structural shift.
For institutional-flow watchers, subsequent sessions will provide the stronger signal. Persistent Bitcoin and Ether redemptions alongside continued XRP inflows would offer clearer evidence of changing allocation preferences, while a rapid return to positive flows would suggest September 8 was primarily another example of short-term ETF volatility.
