According to an FT article, CoreWeave, which supplies artificial intelligence (AI) computing power to Microsoft, was facing delivery issues and missed deadlines, causing the tech giant to reduce its commitments, though it remains a major partner.
Microsoft represents 62% of CoreWeave’s revenue and has pledged over $10 billion in spending on its services by 2030. CoreWeave has rapidly grown, generating $1.9 billion in revenue in 2024 but posting significant losses.
It relies heavily on Nvidia’s (NVDA) AI chips and has raised $14.5 billion in debt and equity. Microsoft’s decision aligns with its shifting AI infrastructure strategy, though it remains committed to major investments in the sector.
