Google and CoreWeave have raised a combined $6.7 billion in junk bonds.

As reported by Bloomberg, Google has secured $5.7bn in debt, while CoreWeave racked up the remaining $1bn last week.

The Google bonds were led by Morgan Stanley, Bloomberg said, citing people with knowledge of the matter, and will be used to fund the construction of two data centers in Sullivan County, Indiana, being developed for Fluidstack.

Details of the project have yet to be publicly released. Google is known to be backing AI cloud firm Fluidstack for around $1.3bn of its long-term lease obligations. If Fluidstack becomes insolvent or defaults on a lease payment, Google has the option to pay a lease termination fee or take on the lease as a tenant on a discounted rate. This includes data center projects in Texas and Louisiana.

In February 2026, Google secured $32bn in bonds to help support its rising capex. The cloud and search giant is expecting a 2026 capex of up to $185bn, a large portion of which will go on data centers and AI infrastructure.

CoreWeave, meanwhile, has sold $1bn of 2031 bonds with a 9.75 percent interest rate. Just one week prior, the neocloud sold $1.75bn in its initial 2031 notes offering.

In late March 2026, CoreWeave secured an $8.5bn loan to support its GPU purchases for a Meta contract. The neocloud has been racking up its debt to fund its build-out, with the company amassing some $21.6bn in debt by the end of last year. Earlier this year, CoreWeave secured another $2bn in investment from Nvidia.
