BlackRock to Reverse Split Its Largest Ethereum ETF on October 6

BlackRock is set to implement a 1-for-3 reverse stock split for its spot Ethereum ETF (ticker: ETHA) on October 6, 2026. The move will reduce the number of shares outstanding while increasing the share price, without altering the fund’s net asset value or investor ownership. Analyst Eric Balchunas noted that this could narrow ETHA’s trading spread from 7 basis points (bps) to about 2 bps, potentially improving liquidity.

The reverse split will convert every three old shares into one new share. BlackRock’s ETHA, the largest U.S. spot Ether ETF with over $5 billion in assets under management, has seen significant inflows, leading with $42.46 million in a single day. Balchunas also highlighted that the price of ETHA will rise from $14 to $42 post-split.

While BlackRock did not specify the reason for the reverse split, such actions are typically taken to enhance trading efficiency or meet exchange listing requirements. As of the report, Ethereum was trading near $1,871, with retail sentiment around ETHA remaining bearish on Stocktwits.

The filing for the reverse split was submitted to the U.S. Securities and Exchange Commission (SEC) on Tuesday. Other major Ethereum ETFs, including Fidelity’s FETH and Bitwise’s ETHW, also saw notable inflows, though ETHA remained the leader in this regard.
