The streak of inflows into spot Ether (ETH) exchange-traded funds (ETFs) has continued, reaching 15 consecutive days as of June 7, 2025. This remarkable run has resulted in a cumulative inflow of $837.5 million, signaling strong and sustained investor interest in the cryptocurrency through regulated investment products.

The current inflow streak, spanning three consecutive trading weeks, accounts for approximately 25% of the total net inflows since the spot Ether ETFs were first launched in July 2024. This indicates a significant acceleration in investment activity in recent weeks.

BlackRock's iShares Ethereum Trust (ETHA) has emerged as a dominant player in the spot Ether ETF market. The fund has attracted nearly $576 million in inflows, representing 71% of the total two-week inflow. ETHA's cumulative net flows have surpassed $4.8 billion, making it the absolute leader in the Ethereum ETF space. Fidelity's Wise Origin Ether Fund (FETH) follows with roughly $123 million in inflows over the past 14 days. FETH is the second-largest Ethereum ETF by inflows, though its cumulative net flows of $1.5 billion are less than ETHA's.

On June 5, US Spot Ethereum ETFs collectively recorded a net inflow totaling $11.3 million, marking the 14th consecutive trading day where more money flowed into these ETFs than out. BlackRock's ETHA was the clear leader for the day, registering a substantial net inflow of $34.7 million. In contrast, Fidelity's FETH experienced a net outflow of $23.4 million, which could be due to portfolio rebalancing or shifts between different investment products.

The sustained inflows into spot Ethereum ETFs suggest increasing confidence and demand from the market, particularly from traditional finance players seeking regulated ways to access the second-largest cryptocurrency. This bullish sentiment is further supported by the SEC's clarification that ETH staking does not constitute a security offering, potentially paving the way for funds to offer staking within ETH ETFs.

Despite the positive momentum in ETF inflows, Ethereum's price has traded largely sideways since May 13, hovering between $2,450 and $2,700. This price stagnation may be attributed to rising short positions across Ethereum futures, which could be neutralizing the impact of buying pressure in the spot market.

Nevertheless, analysts believe that the continued demand for spot Ethereum ETFs and a strengthening market structure may trigger a significant breakout for Ether. The rise in the ETH/BTC ratio indicates increased demand for Ether, with institutional investors potentially favoring ETH over BTC in recent days.
