Morgan Stanley filed a second amendment to its Form S-1 registration statement for the proposed Morgan Stanley Bitcoin Trust on March 17, 2026, adding operational details including a planned NYSE Arca listing under ticker MSBT and a $1 million seed capital structure, though the product remains unapproved and cannot be sold until the SEC declares the registration effective.
What Morgan Stanley changed in its latest Bitcoin ETF filing
The Amendment No. 2 to Form S-1, filed with the SEC on March 17, marks the third iteration of the registration statement since Morgan Stanley first submitted the original S-1 on January 6, 2026. An interim Amendment No. 1 followed on March 4.
The latest filing states that shares of the Morgan Stanley Bitcoin Trust are expected to list on NYSE Arca under the ticker symbol MSBT. That detail, absent from the original filing, signals the bank has moved past early-stage structuring into exchange-level planning.
Morgan Stanley already distributes BlackRock’s iShares Bitcoin Trust (IBIT) through its adviser network. Marcin Kazmierczak, co-founder of RedStone, noted that the bank “is moving from distributing BlackRock’s IBIT to issuing its own product, capturing management fees directly rather than earning distribution commissions.”
Key details inside the amended prospectus
The amended filing names The Bank of New York Mellon and Coinbase Custody Trust Company as bitcoin custodians for the trust. The dual-custodian arrangement pairs a traditional financial institution with a crypto-native firm, a structure similar to what other institutional players exploring digital asset custody have adopted.
The delegated sponsor expects to purchase 50,000 initial seed shares for total anticipated proceeds of $1 million. Those proceeds are intended to buy bitcoin for the trust ahead of any public listing.
A basket size of 10,000 shares is specified in the filing. Baskets are the creation and redemption units used by authorized participants to manage ETF share supply, and their size determines the minimum block for institutional transactions.
The combination of named custodians, defined seed capital, and a set basket size represents a level of operational specificity that goes beyond a placeholder filing. For context, Coinbase has been expanding its institutional crypto infrastructure across multiple product lines, and its role as custodian here reinforces that positioning.
Why the filing still falls short of full SEC approval
Despite the added detail, the prospectus explicitly states that the registration statement is preliminary. Securities may not be sold until the SEC declares the registration statement effective.
The filing timeline shows steady procedural progress: the original S-1 landed on January 6, 2026, Amendment No. 1 followed on March 4, and Amendment No. 2 arrived on March 17. Each iteration has added specificity, but filing amendments is a standard part of the SEC registration process, not a signal of imminent approval.
No SEC notice of effectiveness for the Morgan Stanley Bitcoin Trust registration statement has been publicly issued. Separately, no NYSE Arca 19b-4 exchange listing approval specific to this trust has been verified.
The distinction matters for investors tracking the growing institutional push into crypto products. An amended S-1 shows Morgan Stanley is refining its application, but the trust cannot accept investor capital or begin trading until both the SEC registration and exchange listing processes are complete.
Morgan Stanley’s entry would make it the first major U.S. bank-affiliated asset manager to launch its own spot Bitcoin ETF, moving beyond distribution agreements into direct product issuance. The next milestone to watch is whether the SEC declares the registration statement effective, which would clear the path toward a public launch.
