Spot Ethereum ETFs are attracting heavy attention from institutional buyers. On September 11, 2025, they saw $113.12 million in fresh inflows, a sharp reversal after five straight days of outflows earlier in the month. Advisers are leading the charge, adding more than $1.3 billion worth of ETH in Q2 alone, a 68% rise compared to the previous quarter.
BlackRock’s Ethereum ETF currently manages around $16 billion, while Fidelity’s FETH holds $3.5 billion. Combined, spot ETH ETFs have now pulled in $10.83 billion since May 2025.
This steady inflow highlights how ETH is being adopted as a serious tool for portfolio diversification, sitting alongside stocks and bonds.
Meanwhile, Bitcoin ETFs recorded outflows of $751 million in August, while Ether ETFs drew in $3.87 billion, sparking debates about whether ETH could eventually challenge BTC’s market dominance.
With tighter supply on exchanges and growing institutional demand, Ethereum continues to stand out as one of the best altcoins to buy now.
