Bitcoin ETFs Shed $289 Million as Ether Funds Reverse to…

U.S. spot Bitcoin and Ethereum exchange-traded funds returned to net outflows on Tuesday, September 15, reversing Monday’s rebound as cryptocurrency markets sold off following the Senate’s failure to advance the CLARITY Act.Spot Bitcoin ETFs recorded $288.7 million in net outflows, according to Farside Investors’ latest fund-level data. That erased Monday’s $159.9 million inflow and brought the two-session balance to a net withdrawal of approximately $128.8 million.Ether ETFs recorded another $49.5 million in net outflows, reversing part of the $121.1 million they attracted on September 14. The combined Bitcoin and Ether ETF categories therefore lost approximately $338.2 million during Tuesday’s session.The redemptions coincided with a broader risk-off move in crypto. Bitcoin fell roughly 4% to around $75,900 after the Senate voted 49-50 against advancing comprehensive digital-asset market-structure legislation, while Coinbase and Circle shares each dropped roughly 9%.

Fidelity and Grayscale Drive Bitcoin Withdrawals

Fidelity’s FBTC accounted for the majority of Bitcoin ETF redemptions, posting a $214.8 million outflow. Grayscale’s higher-fee GBTC followed with $44.1 million withdrawn, while ARK Invest and 21Shares’ ARKB lost $17.4 million and Bitwise’s BITB shed $12.4 million.Invesco’s BTCO, Franklin Templeton’s EZBC, VanEck’s HODL, WisdomTree’s BTCW, Morgan Stanley’s MSBT and Grayscale’s lower-fee Bitcoin Mini Trust recorded no net movement in Farside’s latest table.BlackRock’s IBIT, normally the largest contributor to category flows, was still marked as unavailable in the dataset rather than zero. The reported $288.7 million category total should therefore be treated as the latest published figure rather than assuming BlackRock experienced no creations or redemptions.The reversal was significant after Monday’s session, when IBIT attracted $134.3 million and FBTC added $53.3 million, helping Bitcoin ETFs break a four-session redemption streak.Cumulative Bitcoin ETF net inflows stood at approximately $55.10 billion based on Farside’s latest figures.

Ether Turns Negative While Solana Stays Flat

Ether ETF selling was smaller but still represented a sharp change from Monday.Bitwise’s ETHW recorded the largest disclosed withdrawal at $34.4 million, while Grayscale’s legacy ETHE lost $17.5 million. 21Shares’ TETH partially offset those redemptions with a $2.4 million inflow, producing the category’s $49.5 million net outflow.BlackRock’s ETHA and ETHB, Fidelity’s FETH and several other funds were still awaiting updated figures in Farside’s table, meaning the total could be revised as remaining issuer data arrive.Solana ETFs, meanwhile, recorded zero net flows on September 15 after attracting $11 million the previous session. Cumulative Solana ETF flows remained approximately $1.33 billion, including seed capital.The September 15 figures mark another rapid shift in institutional crypto positioning. Monday brought broad-based inflows immediately ahead of major Washington events; one session later, Bitcoin and Ether funds were back in negative territory as the failed CLARITY vote, rising Treasury yields and uncertainty ahead of the Federal Reserve decision weighed on risk appetite.
