SEC Opens Comment Window on Grayscale Ethereum Mini Trust Listing

The Securities and Exchange Commission published NYSE Arca’s proposed rule change for the Grayscale Ethereum Mini Trust in the Federal Register on June 3, 2024, opening the proposal to public comment and starting the formal decision period for the exchange listing.

The filing sought permission to list shares under NYSE Arca’s rules for commodity-based trust shares, with the ticker ETH expected if the product reached the market. The publication was an important procedural step, but it was not approval. The SEC’s notice said the associated registration statement was not yet effective and that the shares could not trade until it became effective.

A separate route into spot ether

The Mini Trust was designed as a passive vehicle holding ether rather than derivatives. Each share would represent a proportional interest in the trust’s assets, reduced by expenses and liabilities. Its objective was to track the value of its ether using the CoinDesk Ether Price Index at 4:00 p.m. New York time on each business day.

Grayscale Investments was identified as sponsor, Coinbase Custody Trust Company as custodian and BNY Mellon Asset Servicing as administrator and transfer agent. The proposed structure did not authorize active trading intended to profit from ether-price movements. It also excluded staking: neither the trust nor associated service providers would place its ether into Ethereum proof-of-stake validation to earn additional ether or other income.

The preliminary prospectus dated May 30, 2024 contemplated creations and redemptions in blocks of 10,000 shares. Authorized participants would transact through cash orders, while separate liquidity providers would acquire or dispose of the corresponding ether. The prospectus said definitive regulatory guidance had not yet established whether and how registered broker-dealers could handle in-kind ether transactions under federal securities law.

That detail mattered institutionally. A brokerage-traded security could provide ether exposure without requiring each shareholder to operate a wallet or arrange direct custody, but the wrapper introduced different risks and costs. Shareholders would remain exposed to ether’s market price, possible deviations between the trading price and net asset value, custody and cybersecurity risks, and the gradual reduction of ether represented by each share as trust expenses were paid.

The fee was still unknown

NYSE Arca’s filing described the Mini Trust as having a materially lower sponsor fee than the related Grayscale Ethereum Trust. It did not supply the Mini Trust’s fee rate, stating that the rate would be determined upon listing. The defensible June 3 conclusion was therefore that Grayscale intended to compete on cost, not that investors had been offered a verified price.

The proposal arrived immediately after a broader regulatory shift. On May 23, 2024, the SEC approved exchange rule changes for eight proposed spot ether exchange-traded products, including the conversion proposal for the existing Grayscale Ethereum Trust. Those approvals addressed the exchanges’ ability to list the products; they did not automatically make every registration statement effective or authorize the separately filed Mini Trust.

What June 3 established

Publication on June 3 placed file SR-NYSEARCA-2024-44 into the SEC’s public-review process. Under the timetable stated in the notice, the Commission had 45 days from publication—subject to a permitted extension—to approve or disapprove the proposal or begin proceedings on whether it should be rejected.

The development broadened the prospective lineup of regulated spot-ether products and made fee competition, custody arrangements and cash-only creation mechanics part of the emerging market structure. What remained uncertain on June 3 was equally important: the SEC had not approved the Mini Trust, its registration statement was incomplete, its sponsor fee was unset and no trading date had been established.
