BlackRock Accumulates Millions in Ethereum
The bulk of the purchases came from the ETHA fund, which received approximately $1.27 billion during the analyzed period thanks to consistent capital inflows across multiple consecutive trading days. The firm’s more recent fund, ETHB, also recorded inflows of approximately $296.5 million over the same timeframe. A notable aspect of this fund’s behavior is that it did not register a single day of net outflows during the three weeks analyzed, despite the price volatility that characterized the market during that period.
No Outflows and Steady Demand
The consistency of capital flows into both products led BlackRock to control around 3.56 million ETH, equivalent to approximately $8.69 billion. The sustained growth of that position is largely driven by the daily influx of new capital into its funds, which operate as a channel for institutional exposure to the second-largest cryptocurrency by market capitalization.
The performance of BlackRock’s Ethereum ETFs reinforces a trend that has been accelerating since the launch of ETHB: institutional interest in ETH shows no signs of waning despite short-term price movements, and net inflows remain stable even during weeks of heightened uncertainty.
