Ethereum ETFs have been on a remarkable winning streak, recording net inflows for 15 consecutive trading days as of June 7, 2025. This sustained investor interest has pushed the year-to-date total above the significant $3 billion milestone, signaling growing institutional confidence in the second-largest cryptocurrency .
The Impressive Inflow Streak
The uninterrupted series of positive flows began in mid-May when Ethereum’s price was fluctuating between $2,500 and $2,650. According to the latest data, spot Ethereum ETFs recorded $25.3 million in inflows on June 6 alone, continuing the momentum that has been building for over two weeks .
This consistent pattern of investment follows a particularly strong day on May 22, which saw $110.5 million added to Ethereum ETFs—the largest single-day inflow since early February. By May 30, the cumulative inflows had officially crossed the $3 billion threshold, according to data from Farside Investors.
Leaders in the Ethereum ETF Space
BlackRock’s iShares Ethereum Trust (ETHA) continues to dominate the field, capturing approximately $15.9 million of the June 6 inflows. This ETF has consistently led the pack, accounting for over 70% of the two-week inflow total and amassing more than $4.8 billion in cumulative net flows since its launch .
Fidelity’s Wise Origin Ether Fund (FETH) holds the second position, having attracted roughly $123 million over the past two weeks. While impressive, its total of $1.5 billion in cumulative flows remains significantly behind BlackRock’s offering .
The ETF landscape shows interesting contrasts:
• 21Shares’ CETH represents the smallest Ethereum ETF by inflows, having accumulated just $19.5 million since its July 2024 launch
• Despite Grayscale’s ETHE experiencing nearly $4.3 billion in outflows, the company’s Ethereum Mini Trust has successfully attracted $688 million
Institutional Investors Leading the Charge
The growing interest in Ethereum ETFs is primarily driven by institutional players. Investment advisors currently hold the largest share of declared spot Ethereum ETF exposure, with approximately $582.4 million in holdings based on first-quarter filings .
Other significant institutional participants include:
• Hedge fund managers: $244.7 million
• Brokerages: $159.3 million
• Private equity firms: $39.8 million
• Holding companies: $17.2 million
• Trusts: $11.4 million
Smaller allocations come from pension funds ($7 million), banks ($5.7 million), and family offices ($1.16 million). Collectively, these institutional positions now exceed $1 billion, demonstrating the growing mainstream acceptance of Ethereum as an investment asset .
The continued inflows come despite market volatility, suggesting strong underlying confidence in Ethereum’s long-term prospects as we move through the 2025 market cycle .
