US Spot Ethereum ETFs Achieve $747M in Inflows Over Five Days

US spot Ethereum ETFs have recorded a significant inflow of roughly $746.5 million from September 18 to September 24, marking five consecutive days of net inflows. Notably, no fund experienced an outflow on the final day of this streak.

This surge in inflows highlights an increasing appetite among investors for regulated exposure to Ethereum, bringing the total net inflows since the launch of these ETFs to approximately $13.85 billion. Currently, the total assets under management (AUM) across this product category stand at around $17.7 billion, which accounts for about 5.39% of Ethereum's total market capitalization.

Leading Funds in the Inflow Streak

On September 24, the funds collectively added $66.1 million, with BlackRock’s iShares Ethereum Trust (ETHA) leading the way by attracting $26.8 million. Fidelity’s FETH followed closely with $21.5 million, while Grayscale’s Ethereum Mini Trust brought in $17.8 million. The day prior, September 23, saw an even stronger inflow of $104.5 million.

Comparative Performance with Bitcoin ETFs

Despite this positive momentum, Ethereum ETFs still lag behind Bitcoin ETFs in terms of total capital raised. Bitcoin spot ETFs surpassed the $13 billion cumulative inflow mark much more rapidly after their launch in January 2024, and their total AUM significantly exceeds that of Ethereum funds.

Factors Driving Inflows

The recent uptick in inflows can be attributed to shifting macroeconomic conditions that favor risk assets, alongside Ethereum's historical price movements correlating with sustained ETF inflows. Institutional adoption appears to be broadening, as evidenced by the five-day streak that recorded zero outflows on the final day, indicating that existing holders are not selling even as new capital enters the market.
