Bitcoin exchange-traded funds attract persistent investor demand in the US, but Ethereum equivalents face mounting sell-off momentum.

Data from May 15th on spot cryptocurrency ETFs traded in the US revealed that investor interest remained largely focused on Bitcoin, while exit pressure continued on Ethereum funds.

According to SoSoValue data, Bitcoin spot ETFs recorded a total net inflow of $131 million yesterday, while Ethereum spot ETFs experienced a net outflow for the fourth consecutive trading day. On the Bitcoin side, the strongest performance of the day was exhibited by BlackRock’s spot Bitcoin ETF, IBIT, one of the world’s largest asset management companies. The fund topped the list by attracting a net inflow of $144 million in a single day. This brought IBIT’s historical total net inflows to $65.9 billion. In second place was Bitwise’s BITB fund, which recorded a net inflow of $17.7 million.

On the other hand, the biggest outflow of the day was seen in Grayscale’s GBTC fund. A net outflow of $31.6 million occurred from GBTC, bringing the fund’s total net outflow to date to $26.4 billion. According to the data, the total net asset value of Bitcoin spot ETFs reached $107.7 billion, which is equivalent to 6.61% of Bitcoin’s total market capitalization. Cumulative net inflows exceeded $58.6 billion.

The picture was weaker on the Ethereum spot ETF front. A total daily net outflow of $5.65 million was recorded. The highest net inflow was $6.87 million into Fidelity’s FETH fund. However, BlackRock’s ETHA fund experienced an outflow of $13.2 million.

Ethereum spot ETFs have reached a total net asset value of $13.45 billion, representing 4.85% of Ethereum’s market capitalization. Analysts note that strong inflows into Bitcoin ETFs indicate continued institutional demand, while outflows from Ethereum reflect cautious short-term expectations.
