The Google-related transaction, which received $19 billion in investor orders, will finance two data centers in a Sullivan County, Indiana park. These facilities will be leased to cloud computing startup Fluidstack Ltd., with Alphabet's Google providing a guarantee. Morgan Stanley's $5.7 billion deal marks the largest AI-related high-yield bond issuance in the U.S. dollar market and the largest single-bank-led high-yield offering, priced at 6.25% yield, at the lower end of the price discussion range.

Meanwhile, CoreWeave sold an additional $1 billion in 2031-maturity bonds just one week after its initial offering, capitalizing on sustained investor demand for AI-related transactions amid broader market recovery.

The financing rush reflects acute shortages in data center capacity, GPU chips, and power supplies driven by AI's rapid expansion. Companies are tapping every corner of the debt market, from high-yield bonds to project financing. Morgan Stanley's previous record for a single-bank-led high-yield issuance was $3.2 billion for crypto miner TeraWulf Inc. last year, also backed by Google's guarantee.

Fluidstack, which builds and operates high-performance computing infrastructure for data centers, recently announced a $50 billion deal with Anthropic to construct custom data centers for the large language model maker. The company has also expanded its use of a TeraWulf-operated New York data center, with Google increasing its guarantee to TeraWulf to $3.2 billion and raising its equity stake to approximately 14%.
