BlackRock is set to execute a rare reverse split on its iShares Ethereum Trust ETF (ETHA) on October 6, a move designed to improve trading efficiency and significantly reduce costs for investors seeking Ethereum exposure through traditional brokerage accounts.
What Is the ETHA Reverse Split?
The one-for-three reverse split will consolidate every three ETHA shares into a single share. According to the filing with the U.S. Securities and Exchange Commission (SEC), this adjustment raises the ETF’s share price without altering the total value of investors’ holdings or the fund’s underlying assets. Unlike reverse splits often associated with struggling companies, BlackRock’s action is aimed at optimizing the fund’s trading characteristics when the market price moves outside a preferred range.
Impact on Share Price and Trading Costs
ETHA currently trades around $14.15 per share, reflecting Ethereum’s 37% decline this year from over $3,200 to roughly $1,870. Despite the price drop, the ETF manages about $5.4 billion in assets and has attracted over $11 billion in cumulative net inflows. After the reverse split, the share price will rise to an estimated $42.45, and the number of outstanding shares will drop from 384 million to 128 million. Investor holdings will remain unchanged in total value.
Bloomberg Intelligence ETF analyst Eric Balchunas predicts that the higher share price will narrow ETHA’s bid-ask spread significantly. “This will lower cost to trade from 7bps to 2bps-ish,” Balchunas said, highlighting how ETF issuers work to reduce even small trading costs.
How ETHA Compares to Retail Crypto Platforms
The projected reduction makes ETHA substantially cheaper to trade than many retail cryptocurrency platforms. Balchunas noted that some crypto purchase services, such as those available through Ledger, quoted spreads around 150 basis points, while Coinbase’s simplified buying service charged approximately 140 basis points. Based on these figures, ETHA’s estimated 2-basis-point spread after the reverse split would make trading the ETF roughly 70 times cheaper than certain retail crypto purchases in terms of execution costs alone.
However, the two investment methods serve different purposes. An ETF provides Ethereum price exposure through a traditional brokerage account and charges an annual management fee. Direct cryptocurrency purchases allow investors to transfer assets into self-custody, interact with decentralized applications, and participate in on-chain activities. For those focused primarily on market exposure rather than blockchain utility, BlackRock’s reverse split could further strengthen ETHA’s position as one of the most cost-efficient regulated vehicles for gaining Ethereum exposure.
Frequently Asked Questions
1. What is BlackRock’s ETHA reverse split?
BlackRock will consolidate every three ETHA shares into one on October 6. This raises the ETF’s share price without changing the total value of investors’ holdings or the fund’s assets.
2. Why is BlackRock conducting a reverse split?
According to market analysts, the higher share price could reduce bid-ask spreads, making the ETF cheaper and more efficient to trade while improving overall market liquidity.
3. Will the reverse split affect my investment value?
No. Although you’ll own fewer shares after the split, each share will represent a proportionally larger value, leaving your total investment unchanged, assuming Ethereum’s price remains the same.
4. Why is ETHA considered cheaper than buying Ethereum on Coinbase?
According to Bloomberg ETF analyst Eric Balchunas, ETHA’s trading spread could fall to around 2 basis points, while some retail crypto purchase services charge around 140–150 basis points in execution costs.
5. Should investors choose ETHA instead of buying Ethereum directly?
It depends on the investment goal. ETHA offers regulated Ethereum price exposure through a brokerage account, while direct ETH ownership allows self-custody, staking opportunities (where supported), and participation in blockchain applications.
