The AI cloud infrastructure startup CoreWeave said on Wednesday that Coatue-led investment round had brought in an incredible $1.1 billion for the company.

The Wall Street Journal reports that the acquisition values the company at $19 billion. This is a significant increase from the $2 billion valuation in a Series B extension last May, and it represents an almost threefold increase from the company’s valuation just five months ago, when it was valued at $7 billion after a secondary sale.

Magnetar Capital, which spearheaded CoreWeave’s last primary round, Altimeter Capital, Fidelity Management & Research Co., and Lykos Global Management are among the additional investors in the latest round. According to Crunchbase data, the company has now raised almost $4.6 billion with this most recent funding.

“CoreWeave is designed specifically to tackle the most complex and pressing challenges in high performance compute. With this new round, we will continue investing in and working with the largest AI enterprises in the world,” CoreWeave co-founder and CEO Mike Intrator said in a statement announcing the round.

According to the company, there is “explosive demand for GPU accelerated cloud infrastructure worldwide,” therefore the funds will be used to fund growth, including into new geographic regions.
