Ether ETFs Soar with $837.5M in 15 Days: Institutional Trust Rising?

US-based spot Ether exchange-traded funds (ETFs) have recorded an impressive 15-day inflow streak, amassing $837.5 million since May 16, 2025. On June 6, the ETFs saw $25.3 million in daily inflows, marking a third consecutive trading week of positive flows.

This streak accounts for roughly 25% of the $3.32 billion in total net inflows since the ETFs launched in July 2024. With Ether trading at $2,490, up 31.23% over the past 30 days, institutional investors appear to be doubling down on the second-largest cryptocurrency.

If the trend continues, inflows could surpass $1 billion next week, signaling robust confidence from major players like BlackRock and Fidelity. In contrast, spot Bitcoin ETFs faced a $346.8 million outflow on May 29, highlighting Ether’s relative stability in the ETF market.

Institutional Appetite Fuels Ether’s Rise

The sustained inflows into spot Ether ETFs reflect growing institutional trust in Ethereum’s ecosystem. Major asset managers, including BlackRock and Fidelity, have driven significant capital into these funds, with BlackRock’s iShares Ethereum Trust (ETHA) alone holding over $1.2 billion in assets as of June 2025. Ether's price surge of 31.23% over the past month and the record-low 1.9 million ETH on exchanges underscore strong demand.

Unlike Bitcoin ETFs, which have seen volatile flows, Ether ETFs have maintained consistent inflows, suggesting institutions view Ethereum as a diversified bet in the crypto market. Analysts attribute this to Ethereum’s robust DeFi ecosystem, with over $110 billion in total value locked, and its ongoing network upgrades like the Dencun upgrade, which reduced transaction costs.

Contrasting Bitcoin ETF Volatility

While Ether ETFs enjoy a steady inflow streak, spot Bitcoin ETFs have faced turbulence. After a $346.8 million outflow on May 29, Bitcoin ETFs have seen mixed flows, with only $120 million in net inflows over the past week. This volatility contrasts sharply with Ether’s $837.5 million streak, which could reach $1 billion with an additional $162.5 million in the coming days.

The divergence highlights differing investor sentiments: Bitcoin’s $105,028 price has struggled against macroeconomic pressures, while Ether’s technical strength, including a 65% surge in futures open interest in May, signals bullish momentum.

Institutions may be favoring Ether for its utility in smart contracts and staking potential, with 306,438 ETH currently awaiting validator activation.

Can Ether ETFs Sustain the Momentum?

The question now is whether Ether ETFs can maintain their inflow streak and push past the $1 billion mark. Analysts like James Seyffart note that the introduction of staking ETFs, such as those proposed by REX Shares, could further boost investor interest by offering yield opportunities.

Ethereum’s staking ecosystem has grown, with 255,000 ETH staked in the past eight days, reflecting confidence in long-term returns. However, risks remain, including potential regulatory hurdles and market corrections, especially with short positions in ETH futures rising 20% in June.

As Ether eyes a potential breakout toward $6,000, as suggested by technical patterns resembling gold fractals, the ETF inflow streak could be a key driver in its path to a new all-time high beyond $4,878.
