Morgan Stanley ETF Amendments Put Ethereum And Solana Fee War In Focus

TL;DR Morgan Stanley has reportedly updated proposed Ethereum and Solana ETF filings with a 0.14% sponsor fee. The amended filings include staking language, with most staking rewards expected to remain inside the trusts for investors. The filings are not approvals, but they add pressure to the growing altcoin ETF fee war. Morgan Stanley’s proposed Ethereum and Solana exchange-traded trusts have become the latest focus of Wall Street’s crypto ETF fee war after amended filings disclosed a 0.14% annual sponsor fee and new staking details. The updated S-1/A disclosures, reported from SEC filing materials, apply to proposed Ethereum and Solana products that have not yet received final approval. The filings reportedly show that the trusts would stake a portion of their underlying assets, with 95% of staking rewards retained inside the trust for investors and 5% paid to staking service providers and custodians. That structure is important because fees and staking economics are quickly becoming two of the biggest competitive battlegrounds for altcoin ETFs. Bitcoin ETFs largely competed on cost, brand, liquidity, and custody. Ethereum and Solana products add another layer: what happens to staking rewards? Why A 0.14% Fee Matters A 0.14% annual sponsor fee would position Morgan Stanley’s proposed funds near the low end of the crypto ETF cost spectrum. In plain English, that means investors would pay less in annual fund expenses compared with higher-fee products, assuming the funds are approved and launched as described. Low fees matter because ETF flows can be highly sensitive to cost, especially when products are otherwise similar. If several issuers offer exposure to the same underlying asset, investors and advisers often compare expense ratios closely. Over time, even small fee differences can affect returns, particularly for long-term holders. The fee disclosure also signals that major financial institutions are willing to compete aggressively for crypto ETF assets. That is a very different market from the early years of crypto investing, when access itself was scarce and investors often paid high fees for regulated exposure. Staking Rewards Add A New Competitive Layer The staking component may be even more important than the headline fee. Ethereum and Solana are proof-of-stake networks, meaning holders can earn rewards by participating in network validation through staking. ETF structures have had to deal carefully with this issue because staking can introduce operational, regulatory, tax, liquidity, and slashing risks. According to the filing details described in the source packet, Morgan Stanley’s proposed structure would retain 95% of staking rewards inside the trusts for investors, while 5% would compensate staking service providers and custodians. The sponsor would not take an additional cut of those rewards beyond the stated management fee. That approach could make the products more attractive if regulators allow staking-enabled spot crypto ETFs to move forward. Investors would not simply receive passive price exposure; they could also benefit from staking economics inside the fund structure. Still, the risks should not be ignored. Staking involves validator operations, lock-up mechanics, possible delays, and slashing risk if validators fail or behave improperly. The amended filing language is designed to disclose those risks, not make them disappear. ETF Filings Are Progress, Not Approval The most important caveat is that amended S-1 filings are not approvals. They usually show that an issuer is continuing to work through disclosure, structure, and regulator feedback, but they do not guarantee launch. Even so, the filings show how quickly crypto ETF competition is evolving. Bitcoin opened the door. Ethereum products pushed the market further. Solana filings now show that issuers are already preparing for a broader altcoin ETF landscape. For investors, the key question is whether regulators become comfortable with staking-enabled spot products. If they do, the ETF market may start competing not just on expense ratio, but on how much network yield remains with shareholders. That would make Morgan Stanley’s proposed 0.14% fee and staking reward split more than a filing detail. It could become a template for the next stage of institutional crypto product design.
