Spot Ethereum ETFs in the U.S. have crossed a key milestone, recording 15 consecutive days of net inflows and pushing cumulative investments to a record $3.33 billion. It marks the longest positive inflow streak since late 2024, reflecting renewed investor appetite as Ethereum posts a sharp price recovery.
The rally, which began on May 16 according to data from SosoValue, aligns with Ethereum’s nearly 40% gain over the past month. Leading the surge is BlackRock’s ETHA fund, which has attracted close to $600 million during the period—cementing its leadership in the ETH ETF arena.

While inflow momentum slowed slightly toward the end of the week—with Thursday and Friday seeing the lowest net contributions since May 21—the overall trend remains strong. Analysts attribute the uptick to growing clarity from the SEC and increasing confidence in Ethereum’s staking dynamics, driving institutional and retail interest alike despite a mixed broader market.
Institutional Demand Grows, But Network Use Lags Post-Upgrade
Much of the capital flowing into Ethereum ETFs appears to come from institutional players, encouraged by the network’s recent Pectra upgrade. The upgrade focused on long-term scalability and efficiency improvements. However, analysts at JPMorgan note that this leap in infrastructure has yet to result in a significant boost in user activity.
Instead, Ethereum’s appeal is increasingly centered on its evolving role as an institutional-grade asset—mirroring the narrative that has long surrounded Bitcoin. BlackRock’s ETHA leads in assets under management with nearly $3.3 billion. But in aggregate, Grayscale remains dominant, with over $4 billion combined across ETHE ($2.82B) and ETH ($1.27B). Fidelity trails in fourth with $1.09 billion, while other ETFs in the sector have yet to break the $250 million mark—highlighting how capital remains concentrated among a few major issuers.
Bitcoin ETFs See Pullback After Record-High Inflows
Meanwhile, Bitcoin ETFs experienced a brief setback after reaching a historic high of $45.34 billion in total inflows on May 28. As of the most recent trading session, they’ve dipped by over $1 billion, settling at $44.24 billion. The decline follows market turbulence triggered by a headline-grabbing clash between Donald Trump and Elon Musk, which rippled through both traditional equities and crypto markets.
Despite the short-term dip, BlackRock’s IBIT continues to dominate the Bitcoin ETF landscape with $69 billion in AUM—more than triple the size of its nearest competitors. Fidelity’s FBTC stands at $20.51 billion, followed closely by Grayscale’s GBTC at $19.32 billion. The stark AUM disparity underscores the growing investor preference for newer, lower-fee products over legacy vehicles like GBTC.
