Crypto ETFs Cool Off: Bitcoin Posts $51 Million Outflow, Ether Slips $2 Million

Bitcoin ETFs ended their seven‑day inflow streak with a $51 million outflow, while ether ETFs slipped with a $2 million net exit. Both asset classes saw strong trading volumes but closed the day in the red.

Bitcoin’s Winning Run Ends as Ether Follows With Modest Outflow

The relentless run of inflows into bitcoin exchange-traded funds (ETFs) came to an abrupt halt on Tuesday, Sept. 17. After seven straight days of green, the funds collectively registered a $51.28 million outflow, marking a sharp reversal in sentiment. Ether ETFs followed suit with a smaller $1.89 million decline, leaving both major crypto products in negative territory for the day.

For bitcoin ETFs, the day was a tug-of-war between inflows and outflows. Blackrock’s IBIT stood tall with $149.73 million in new money, and Grayscale’s Bitcoin Mini Trust added $22.54 million. But the exits were far greater. Fidelity’s FBTC led the withdrawals with $116.03 million, Grayscale’s GBTC saw $62.64 million flow out, Ark 21Shares’ ARKB lost $32.29 million, and Bitwise’s BITB shed $12.58 million. Despite the red net figure, trading volumes remained robust at $4.24 billion, with net assets sliding slightly to $152.45 billion.

Fidelity’s FETH faced a $29.19 million exit, and Bitwise’s ETHW recorded $9.67 million in redemptions. These were partially offset by inflows into Blackrock’s ETHA ($25.86 million), Grayscale’s Ether Mini Trust ($6.38 million), Invesco’s QETH ($2.70 million), and 21Shares’ TETH ($2.02 million). Still, the combined flows landed at -$1.89 million. Total trading value reached $2.34 billion, with net assets holding steady at $29.72 billion.

With both bitcoin and ether ETFs dipping in unison, investors are left wondering whether this marks a short-term correction or the first signs of deeper rotation in crypto markets.
