Ethereum Spot ETFs Record $189M Inflows, Largest in 10 Months
On August 19, US spot Ethereum ETFs recorded net inflows of $189.15 million, the highest single-day inflow since October 28, 2025. This influx indicates a resurgence of institutional interest in Ethereum after several months of capital outflows.
The majority of the buying activity was attributed to BlackRock’s ETHA product, which alone absorbed approximately $122 million, representing about 65% of the total inflows for the day. Fidelity’s FETH and Grayscale’s mini ETH fund contributed $36.54 million and $16 million, respectively.
August is proving to be a pivotal month for Ethereum ETFs, with cumulative inflows surpassing $530 million, making it the strongest month of the year thus far. In contrast, May and June saw over $1 billion in net outflows from these funds.
As of now, the total net assets across all US spot Ethereum ETFs stand at around $12.06 billion, which is nearly 4.5% of Ethereum’s overall market capitalization. Additionally, data from Santiment indicates a tightening supply dynamic, with the amount of ETH on exchanges decreasing by approximately 15% over an eleven-week period, dropping from 7.70 million ETH on June 2 to 6.54 million ETH by August 18.
On the same day, Ethereum's price surged 18%, reclaiming the $2,000 level. BlackRock’s significant role in these inflows aligns with trends observed in both Bitcoin and Ethereum ETF markets, suggesting a broader shift in institutional positioning rather than isolated demand for individual products.
