Wu Shuo learned that Morgan Stanley submitted a second revised S-1 filing with the U.S. Securities and Exchange Commission for a Bitcoin ETF application, confirming that Morgan Stanley Bitcoin Trust will be listed on NYSE Arca under the ticker symbol "MSBT", and disclosed that each basket size will be 10,000 shares with initial seed shares of 50,000 shares, with expected fundraising of approximately 1 million U.S. dollars; it was previously disclosed that BNY Mellon and Coinbase will serve as Bitcoin custodian and related functions respectively; this revision indicates the application has made progress but does not guarantee approval. If approved, Morgan Stanley could become the first major U.S. bank to directly issue a spot Bitcoin ETF.
