Morgan Stanley, a global investment bank and asset management firm, filed an Amendment No. 4 to its registration statement on Form S-1 with the U.S. Securities and Exchange Commission (SEC) on April 1 for Morgan Stanley Bitcoin Trust, outlining plans to list an exchange-traded fund (ETF) based on Bitcoin on NYSE Arca under the ticker MSBT. The application describes a passive instrument designed to track the price movements of Bitcoin using a benchmark index. Bloomberg ETF analyst James Seiffart shared his opinion on the updated application and potential timelines on social media platform X. "BREAKING: Morgan Stanley's updated application for their Bitcoin ETF $MSBT. Looks like minor changes, which I assume are based on SEC feedback/comments," he said, adding: "My main assumption is that this is the final change before receiving the final prospectus and launching the product next week."
