BlackRock will execute a one-for-three reverse split of its spot Ethereum ETF on October 6, combining every three ETHA shares into one. Investor holdings and total fund value remain unchanged.
The restructuring compresses the share price, a common move in equity markets to reduce per-share trading costs. Eric Balchunas, senior ETF analyst at Bloomberg, said the split could cut the fund's bid-ask spread from 7 basis points to 2 basis points, lowering friction for institutional traders moving large positions. ETHA, which manages $5.58 billion in assets as of early August, is the second-largest spot Ethereum ETF after Fidelity's FETH.
Reverse splits typically make shares appear less volatile in nominal terms and can improve execution quality when spreads compress. The structure has no economic impact on shareholders; a holder of 300 shares worth $100 each will own 100 shares worth $300 each after October 6. BlackRock filed the change with the SEC under standard ETF modification procedures.
The move arrives as spot Ethereum ETFs, approved by U.S. regulators in July 2024, have accumulated roughly $12 billion in combined assets. Competition for inflows among Ethereum ETF providers has intensified, with expense ratios and trading efficiency becoming differentiators. Fidelity's FETH charges 0.20 percent annually; BlackRock's ETHA charges 0.25 percent.
A tighter bid-ask spread on ETHA could improve its competitive position against Fidelity and other providers including Grayscale and Franklin Templeton, all of which offer spot Ethereum exposure. Institutional allocators often route large trades through ETFs with the lowest friction costs, making execution quality a material factor in fund selection.
BlackRock's Ethereum ETF has held roughly 10 percent of total spot Ethereum ETF assets since launch. If the bid-ask compression Balchunas described materializes, the fund's appeal to large institutional traders could grow. The document to watch is BlackRock's amended prospectus filing on the SEC Edgar platform; it will specify the exact ex-date and payment schedule for the split.
