Ethereum ETFs Post Substantial Inflows Amid Minor Outflows

Ethereum ETFs collectively hold 4,110,246 ETH, with a market value close to $9.94 billion. The largest Ethereum fund, iShares Ethereum Trust, manages 1,768,573 ETH. On the reported day, it recorded a net inflow of 2,421 ETH and a seven-day inflow of 87,767 ETH.

The Fidelity Ethereum Fund also saw large inflows, adding 10,237 ETH in one day and 13,233 ETH over seven days. In contrast, the Grayscale Ethereum Trust and Mini Trust reported small outflows, losing 232 ETH and 7 ETH, respectively, during the day.

ETF Inflows Reflect Institutional Accumulation Trends

Inflow data indicates that institutional investors are gathering in Bitcoin and Ethereum through ETF products. iShares funds from BlackRock lead both markets with consistent gains in market share via large daily and weekly summations.

Flows of liquidation in some Grayscale trusts are only local adjustments and cannot be used to offset the general trend of accumulation that defines the industry. The huge net inflows over the first few days of July suggest that large investors and funds managers continue to be comfortable with these cryptocurrencies.
