BlackRock’s iShares operation established the iShares Ethereum Trust on November 9, 2023, creating the legal vehicle for a proposed exchange-traded product designed to hold ether. The dated certificate of trust identifies a trustee associated with BlackRock Advisors and states that the Delaware statutory trust would become effective immediately upon filing.
A Nasdaq Rule 19b-4 proposal published later on November 9 supplied the product’s intended structure: shares representing interests in ether held for the trust, Coinbase Custody Trust Company as the proposed ether custodian, and the CME CF Ether-Dollar Reference Rate–New York Variant as its principal benchmark. The combination transformed an initially ambiguous Delaware registration into a documented institutional product plan.
What the November 9 records established
The certificate created a legal entity; it did not create a publicly traded fund. Nasdaq’s proposal described an investment objective of reflecting ether’s price before expenses and liabilities and sought permission to list the shares as Commodity-Based Trust Shares.
The proposal said the benchmark would aggregate eligible ETH/USD trades from constituent spot platforms during a 3:00 p.m. to 4:00 p.m. Eastern observation window. It also described shares as an alternative to acquiring and safeguarding ether directly. Those were proposed mechanics, not operational facts on November 9: no shares were trading, the related registration statement was not yet effective, and regulatory approval remained necessary.
Nasdaq and the sponsor advanced a broader regulatory argument. Because the Securities and Exchange Commission had permitted exchange-traded funds holding CME ether futures, they contended that surveillance of the futures market could also address manipulation affecting a spot product. That was the applicants’ position, not an SEC finding or approval.
Why the move mattered
The filing extended the institutional race for spot cryptocurrency products from bitcoin to Ethereum’s native asset. It also placed familiar securities-market infrastructure—exchange listing rules, a daily benchmark, regulated custody and authorized participants—around direct ether exposure.
That distinction mattered in November 2023. Ether-futures funds already existed, but a trust holding spot ether would expose shareholders more directly to the underlying asset’s price while adding product-level fees, custody arrangements and potential deviations between share price and net asset value. The proposal therefore raised both an access question and a regulatory-consistency question: whether surveillance arguments accepted for futures-based products could support a spot product.
Formation of the trust did not establish demand, safety, liquidity or legal acceptance. It also did not resolve how the SEC viewed ether under federal securities law. The verified development was narrower but still consequential: BlackRock had moved beyond general interest and created a named vehicle for a proposed spot-ether product.
The event-day market reaction
Ether moved sharply after the records became public. The Block reported a CoinGecko snapshot of $2,066 at 4:43 p.m. Eastern on November 9, up 9.9% over CoinGecko’s rolling comparison window. CoinDesk separately reported that ether approached $2,100 and was about 3% above its level immediately before the Nasdaq document appeared.
Those observations are not an official closing price. Cryptocurrency trades continuously, CoinGecko aggregates multiple venues, and the reports captured intraday or rolling 24-hour windows rather than a regulated closing auction. The timing supports describing a contemporaneous reaction, but it does not prove that the trust documents alone caused the entire move.
Later record, kept separate
BlackRock filed the trust’s Form S-1 registration statement on November 15, 2023, corroborating that the trust had been formed on November 9 and supplying fuller proposed terms. The SEC’s surviving rulemaking docket records a subsequent Nasdaq submission received on November 21 and an SEC notice dated December 5. Those later procedural milestones clarify the sequence; they should not be projected backward as approvals or completed filings on November 9.
