Morgan Stanley is finalizing the sale of another $3 billion of X Holdings Corp. debt, making further progress in a years-long effort to offload loans that supported Elon Musk’s tumultuous purchase of the social-media platform.

Morgan Stanley (NYSE:MS) is reportedly planning to increase the size of its latest X Holdings Corp. debt offering, according to Bloomberg News, citing sorces familiar with the matter. The decision comes in response to robust investor demand.

Morgan Stanley advised Musk on the purchase, led the financing and sales and also held the largest chunk of X debt. Other holders include Bank of America Corp., Barclays Plc, Mitsubishi UFJ Financial Group Inc., BNP Paribas SA, Mizuho Financial Group Inc. and Societe Generale SA.
