Spot Ether ETFs record $729M inflows in second-largest daily rise

Spot Ether ETF inflows hit $729.1 million on Wednesday, marking the second-largest daily total since the U.S. approved Ethereum exchange-traded funds earlier this year. The surge underscores accelerating institutional demand and helped push ETH to $4,775, just shy of its all-time high.

BlackRock’s ETHA led with $500.9 million in new investments, followed by Fidelity’s FETH with $154.7 million. Four other Ether ETFs also saw positive contributions, extending a three-day streak of inflows.

Over that period, Spot Ether ETF inflows totaled $2.2 billion — nearly seven times the $330.9 million that flowed into Bitcoin ETFs.

“Ethereum’s trajectory shows the market is recognizing its unique role in decentralized finance and beyond,” — Emily Carter, senior analyst at Digital Asset Research, told Market Insight Weekly.

Ethereum ETFs dominate Bitcoin counterparts

On Wednesday alone, Ethereum funds drew $704 million, compared with just $86.7 million for Bitcoin ETFs. The rapid accumulation of Spot Ether ETF inflows has coincided with a 60% monthly price increase, fueling both investor optimism and short-seller losses.

CoinGlass data shows that $127.4 million in short positions were liquidated in the last 24 hours, underlining the rally’s market impact.

Institutional buying is also constraining supply. Since Ethereum’s “Merge” upgrade in September 2022, only about 450,000 ETH has been issued, yet monthly Spot Ether ETF inflows are equivalent to roughly 500,000 ETH. “Supply and demand are aligning in Ethereum’s favor, and ETFs are amplifying that effect,” — Mark Ruiz, portfolio strategist at Arcadia Digital, said in an interview.

Corporate treasuries deepen the ETH supply squeeze

Crypto-focused corporations are also boosting demand. BitMine Immersion, the world’s largest corporate holder of Ethereum, disclosed plans to raise its acquisition fund from $4.5 billion to $24.5 billion. The move aims to secure additional ETH reserves at a time when Spot Ether ETF inflows are already pressuring available supply.

However, Ethereum co-founder Vitalik Buterin has urged caution. In a recent interview, he warned that excessive leverage within Ethereum-focused corporate treasuries could create systemic risks.

“If you woke me up three years from now and told me that treasuries led to the downfall of ETH… my guess would basically be that somehow they turned it into an overleveraged game,” Buterin said.

Skepticism over the rally’s sustainability

Some industry figures remain wary. Samson Mow, CEO of Bitcoin adoption firm Jan 3, argued that a portion of current Spot Ether ETF inflows may be driven by tactical asset rotation rather than long-term conviction.

Mow claims that many early ETH investors, especially from the initial coin offering era, already hold substantial Bitcoin reserves. He believes some are selling Bitcoin to buy ETH, temporarily boosting prices before selling their Ether holdings and returning to Bitcoin.

“No one wants ETH in the long run,” Mow said, warning that Ethereum may face what he calls the “Bagholder’s Dilemma” — growing selling pressure as the price approaches its previous all-time high.

The road ahead

For now, Spot Ether ETF inflows remain one of the clearest indicators of Ethereum’s rising prominence in the institutional investment landscape. Whether this momentum can be sustained will depend on continued investor confidence, market liquidity, and the absence of destabilizing leverage in corporate holdings.

With inflows already surpassing most market expectations, the next few weeks could determine if Ethereum breaks new records or faces a sharp correction.
