BlackRock's ETHA fund added $787.2 million of Ethereum to its holdings over the last 20 trading days, while its ETHB fund purchased $221.2 million. The combined $1.01 billion accumulation represents a concentrated period of buying by the world's largest asset manager across its spot ETF offerings.

The ETHB fund recorded net inflows on 13 of the previous 14 trading days. This activity occurred alongside a broader market recovery that saw U.S. spot Ether ETFs attract $270 million on Sept. 21, the largest single day inflow for those products since Oct. 7, 2025.
