May 17 (Reuters) - Specialized cloud services provider

CoreWeave is raising $7.5 billion in debt from financiers led by

Blackstone and Magnetar to expand its infrastructure to

meet rising artificial intelligence (AI) workloads, it said on

Friday.

The deal is one of the largest debt financing rounds for a

startup and adds firepower to CoreWeave's balance sheet as it

looks to expand its cloud computing services to more customers.

The Nvidia ( NVDA )-backed company has raised more than $12

billion in equity and debt investments over the past 12 months,

including a $1.1 billion series C investment led by private

equity firm Coatue earlier this month.

"The caliber of investors in this large debt financing round

is a powerful testament to ... the insatiable market appetite

for AI infrastructure," CEO and co-founder Michael Intrator said

in a statement.

Coatue, Carlyle, CDPQ, DigitalBridge Credit, funds

managed by BlackRock ( BLK ), Eldridge Industries and Great Elm

Capital Corp were also part of CoreWeave's latest debt raise.

CoreWeave has seen a boost from businesses rapidly adopting

generative AI technology. It has partnerships with AI startups

and competing cloud providers to build clusters to power AI

workloads.
