The race for a spot Ethereum ETF intensifies on February 21, 2024, as Coinbase formally urges the U.S. Securities and Exchange Commission to approve Grayscale’s application to convert its $5 billion Ethereum Trust into a publicly traded fund. The filing, a comprehensive 27-page response with 96 citations, lands at a critical juncture — just as S&P Global raises concerns about the potential concentration risks that Ethereum staking ETFs could introduce to the network’s validator ecosystem.
TL;DR
- Coinbase files a 27-page response with 96 citations urging SEC approval of Grayscale’s spot Ethereum ETF
- Coinbase Chief Legal Officer Paul Grewal presents legal, technical, and economic rationale for approval
- Grayscale seeks to convert its $5 billion Ethereum Trust (ETHE) into a spot ETF on NYSE Arca
- S&P Global warns that staking ETFs could concentrate Ethereum’s validator set among institutional custodians
- Lido currently dominates Ethereum staking with $29.2 billion TVL and 31% market share
- Coinbase serves as custodian for 8 of the 11 approved spot Bitcoin ETFs
Coinbase Mounts a Comprehensive Case for Ethereum ETF Approval
Coinbase’s filing represents one of the most detailed public arguments in favor of a spot Ethereum ETF to date. Chief Legal Officer Paul Grewal shares the submission on social media, highlighting that Coinbase’s response addresses three pillars: the legal basis for approval, the technical readiness of Ethereum’s market infrastructure, and the economic rationale demonstrating that the conditions for a spot ETF are met.
The filing emphasizes Ethereum’s classification as a commodity rather than a security — a distinction that carries enormous regulatory implications. By asserting Ethereum’s commodity status, Coinbase aims to provide the SEC with a clear framework for approving the ETF under existing securities law precedents, particularly following the agency’s January 2024 approval of 11 spot Bitcoin ETFs.
Grayscale initially applied in October 2023 to convert its Ethereum Trust, which holds approximately $5 billion in assets, into a spot ETF. NYSE Arca, the exchange expected to list the fund, submitted the proposal on Grayscale’s behalf. Grayscale CEO Michael Sonnenshein has publicly advocated for approval, arguing that the same regulatory logic that justified Bitcoin ETFs applies equally to Ethereum.
S&P Global Raises Concentration Risk Alarm
While the ETF approval momentum builds, a February 20 report from S&P Global introduces a cautionary note. Analysts Andrew O’Neill and Alexandre Birry warn that the introduction of Ethereum staking ETFs could significantly alter the composition of the network’s validator set, potentially introducing new concentration risks for the Ethereum blockchain.
The concern centers on the mechanics of Ethereum’s proof-of-stake consensus mechanism. When ETF issuers include staking functionality in their products, they must select a custodian or staking provider to handle the ether on behalf of ETF shareholders. S&P Global’s analysts note that while institutional custodians could reduce the current dominance of decentralized staking protocol Lido, the shift could simply replace one concentration risk with another if a single entity is chosen to stake the bulk of ether included in these ETFs.
Lido, the largest Ethereum validator, currently holds $29.2 billion in total value locked and commands approximately 31% of the liquid staking market. While Lido’s protocol relations contributor Marin Tvrdic has emphasized that the protocol operates on a non-custodial basis — meaning neither the DAO nor the protocol holds custody of users’ ether — the sheer scale of its market share has long raised concerns about centralization on the Ethereum network.
The Coinbase Custody Connection
S&P Global’s analysts point to a particularly relevant dynamic: Coinbase already serves as the custodian for eight of the eleven spot Bitcoin ETFs approved in January 2024, and is named as a staking institution by multiple Ethereum ETF applicants. If Coinbase were to become the dominant staking provider for spot Ethereum ETFs, the concentration of Ethereum’s validator set could shift dramatically toward a single corporate entity.
This creates a paradox for regulators and market participants alike. The institutional credibility that Coinbase brings to the ETF ecosystem — the very quality that makes it an attractive custodian for fund issuers — could simultaneously undermine the decentralization principles that make Ethereum valuable in the first place. The SEC must now weigh these competing considerations as it evaluates the pending Ethereum ETF applications.
Regulatory Timeline and Market Expectations
The SEC faces a May 2024 deadline for several pending Ethereum ETF applications, creating a compressed timeline for decision-making. Market participants broadly expect the agency to reach a decision by late May, though the regulatory outcome remains uncertain. Executives from Grayscale, Bitwise, and Galaxy have estimated a roughly 50% probability of approval, reflecting both the strong precedent set by Bitcoin ETF approvals and the unique regulatory questions that Ethereum’s staking functionality raises.
The regulatory debate extends beyond simple approval or denial. The structure of any approved ETF — particularly whether it includes staking functionality and how that staking is managed — could have profound implications for Ethereum’s network architecture, validator distribution, and long-term decentralization trajectory. S&P Global’s report underscores that the design choices made by ETF issuers and approved by regulators will shape Ethereum’s consensus landscape for years to come.
Why This Matters
The collision of Coinbase’s aggressive ETF advocacy and S&P Global’s concentration risk warning encapsulates the central tension in cryptocurrency’s institutional evolution. On one hand, spot Ethereum ETFs represent a watershed moment for mainstream adoption, potentially unlocking billions in institutional capital and validating Ethereum’s status as a mature, regulated asset class. On the other hand, the infrastructure required to support these products — custodians, staking providers, and regulated market makers — could inadvertently centralize control over a network designed to be decentralized.
For investors and market watchers, the key development is that the Ethereum ETF conversation has moved beyond “will it be approved?” to “how will it be structured?” The answer to that second question could determine not just the price of ETH, but the fundamental character of the Ethereum network itself. As the SEC deliberates, every stakeholder — from Grayscale and Coinbase to S&P Global and individual validators — is watching closely.

27 pages and 96 citations. Paul Grewal went full legal nuclear on the SEC. The commodity-not-security argument was the whole ballgame.
Lido at $29.2B TVL with 31% market share is the concentration risk S&P was actually worried about. Not just staking ETFs.
