Bloomberg Markets reports that companies financing data center projects are increasingly turning to junk bond investors to raise billions of dollars. For example, QTS Realty Trust this week sold $3.9 billion in bonds for a Microsoft-related facility in Georgia. Although these bonds were highly rated, they offered a yield of approximately 7.23%. Additionally, blue-chip securities sold by BlackRock in July for a data center project in Texas also provided a yield of 7.53%.
