Morgan Stanley has submitted an amended S-1 filing with the Securities and Exchange Commission for its proposed Solana exchange-traded fund, moving the product one step closer to a potential listing on NYSE Arca under the ticker MSOL.
The S-1/A filed on May 20, 2026, is labeled Amendment No. 1 to the original registration statement for the Morgan Stanley Solana Trust. The bank first filed the initial S-1 on January 6, 2026, alongside a separate registration for a Bitcoin trust.
What Changed in the Amended Solana ETF Filing
The amended prospectus lays out the trust’s investment objective: track Solana using the CoinDesk Solana Benchmark 4PM NY Settlement Rate, adjusted for expenses and liabilities, while reflecting staking rewards. Notably, the delegated sponsor intends to stake up to 100% of the trust’s SOL holdings under normal market circumstances.
That staking provision is a differentiator. While other crypto ETF filings have addressed staking in varying degrees, committing to stake the full portfolio signals Morgan Stanley’s intent to pass yield through to fund performance, not just track a passive price index.
The filing names Bank of New York Mellon and Coinbase Custody Trust Company as SOL custodians. BNY’s role extends beyond simple custody; the bank also serves as administrator, transfer agent, and cash custodian for the trust.
Creations and redemptions will be handled in baskets of 10,000 shares, with the trust anticipating $1 million in initial seed proceeds tied to 50,000 seed shares.
One detail the amendment does not resolve: the delegated sponsor fee remains blank, listed as “[ ]%” in the prospectus. That placeholder suggests further amendments or a final pricing decision are still pending before the fund can launch.
Another structural provision worth noting is that the delegated sponsor retains the right to change the benchmark index or benchmark provider via website disclosure and Form 8-K notice, without requiring shareholder approval.
Why the Solana ETF Update Matters for Altcoin Markets
Morgan Stanley is the largest U.S. wealth management firm to pursue a spot Solana ETF. The amended filing reinforces that institutional interest in altcoin-based investment products extends beyond Bitcoin and Ethereum, the two assets that have already secured ETF approvals.
SOL traded at $85.69 during the filing window, up roughly 1.2% over 24 hours, with a market capitalization near $49.5 billion.
Broader crypto sentiment remains cautious. The Fear & Greed Index sat at 29 on the day of the filing, firmly in “Fear” territory. Secondary coverage on Stocktwits noted that SOL retail sentiment remained bearish with normal chatter volume on May 20.
The filing arrives during a period of heightened regulatory scrutiny across crypto markets. Missouri’s attorney general recently sued crypto ATM operator CoinFlip over alleged scam enablement, and Binance announced a temporary suspension of ETH deposits and withdrawals tied to network upgrades. Against that backdrop, a major bank pushing forward with a Solana ETF amendment stands out as a constructive institutional signal.
ETF progress for altcoins beyond Bitcoin and Ethereum has been a key narrative for the sector. A Morgan Stanley-backed product reaching the amendment stage lends credibility to the idea that regulated Solana exposure could eventually be available through traditional brokerage accounts.
What Comes Next After the Amended Filing
An amended S-1 is a procedural step, not an approval. The filing itself states that the registration statement is not yet effective and that securities may not be sold until the SEC declares it effective.
The blank fee field and the “Amendment No. 1” label suggest Morgan Stanley expects additional rounds of revision. Typical ETF registration processes involve multiple S-1 amendments before a final prospectus is declared effective, and a parallel 19b-4 filing from the listing exchange (NYSE Arca, in this case) must also clear SEC review.
The original Morgan Stanley announcement confirmed that both the Solana Trust and Bitcoin Trust products remain pending regulatory approval. That status has not changed with this amendment.
Traders watching for progress should monitor SEC EDGAR for subsequent S-1/A filings and for any 19b-4 rule change proposal from NYSE Arca. The fee disclosure, once it appears, will also signal how close the product is to a launch-ready state.
Security incidents elsewhere in the ecosystem, such as the recent Butter Network bridge exploit that hit MAP Protocol, could also factor into the SEC’s broader risk assessment of altcoin-based products. Whether that lengthens the review timeline remains an open question.
