Ethereum spot ETFs experienced a net outflow of $30.043 million on June 29 (EST), breaking a streak of consecutive net inflows. According to SoSoValue data, total net assets of all Ethereum spot ETFs fell to $8.594 billion, with a net asset ratio (market cap relative to total Ethereum market cap) of 4.4%. Historical cumulative net inflows remained at $10.873 billion.
Detailed Fund Flow Breakdown
Among the 11 Ethereum spot ETFs, the largest net inflow came from BlackRock's ETHA, which gained $5.869 million on the day, bringing its historical net inflow to $11.086 billion — the highest among all Ethereum ETFs. Fidelity's FETH followed with a net inflow of $5.252 million, accumulating a total of $2.113 billion historically.
However, BlackRock's Staked ETH ETF (ETHB) saw a significant net outflow of $37.549 million, the largest single-day exit among all Ethereum ETFs. ETHB's historical net inflow stands at $520 million, meaning yesterday's outflow erased a substantial portion of recent capital. As a staking-focused ETF, this sharp retreat may reflect shifting sentiment among investors toward yield-bearing ETH products.
Other ETFs showed relatively minor movements, with the overall net outflow dominated by ETHB. As of press time, the total net asset value of Ethereum spot ETFs was $8.594 billion, representing 4.4% of Ethereum's total market capitalization. The cumulative net inflow since inception reached $10.873 billion (adjusted for ETHB's outflow).
Market Interpretation and Key Takeaways
While the headline net outflow of $30 million is modest, the magnitude of ETHB's outflow is noteworthy. The fund has accumulated approximately $520 million since launch, so yesterday's $37.5 million exit represents about 7.2% of its total AUM — a significant one-day withdrawal. In contrast, traditional spot ETFs like ETHA and FETH continue to see steady inflows, indicating sustained institutional appetite for direct Ethereum exposure.
The current total net assets of Ethereum spot ETFs stand at $8.594 billion, implying that ETFs represent only 4.4% of Ethereum's total market cap (estimated at roughly $195 billion at press time). The historical cumulative net inflow of $10.873 billion underscores that Ethereum ETFs have consistently attracted capital since their approval.
Analysts suggest that a single ETF's outflow could be driven by short-term redemption pressures and does not necessarily signal a trend reversal. However, if ETHB continues to see persistent outflows, it may dampen confidence in staking-based ETF products. Meanwhile, the resilient inflows into ETHA and FETH suggest that demand for traditional spot ETFs remains robust.
