Shares of bitcoin miner Core Scientific (NASDAQ: CORZ) experienced a 15% decline in pre-market trading following reports that Microsoft (NASDAQ: MSFT) reduced its commitments to cloud computing provider CoreWeave due to delivery issues and missed deadlines.
This development has raised concerns about CoreWeave’s operational reliability and its impact on partners like Core Scientific.
Microsoft’s Pullback from CoreWeave
Microsoft’s decision to scale back certain agreements with CoreWeave stems from challenges related to delivery issues and missed deadlines. Despite these setbacks, Microsoft maintains a substantial partnership with CoreWeave, involving contracts worth billions of dollars for computing capacity from data centers.
This move reflects Microsoft’s evolving AI strategy and its commitment to ensuring reliable infrastructure for its AI initiatives.
Core Scientific’s Expansion Plans
In February 2025, Core Scientific announced a significant expansion of its data center infrastructure, unveiling plans for a $1.2 billion investment in collaboration with CoreWeave. This expansion aims to bolster Core Scientific’s capacity to support high-performance computing (HPC) operations, including AI workloads. The partnership underscores the strategic alignment between Core Scientific and CoreWeave in addressing the growing demand for AI computing resources.
CoreWeave’s IPO Plans
CoreWeave has laid the groundwork for an initial public offering (IPO) that could value the company at over $35 billion. The company aims to raise $4 billion, positioning itself as a significant player in the AI infrastructure market. This move highlights CoreWeave’s ambition to capitalize on the increasing demand for AI computing power and its commitment to expanding its cloud infrastructure to meet this demand.
CoreWeave’s Reliance on Microsoft
Microsoft is a pivotal customer for CoreWeave, contributing 62% of CoreWeave’s revenue in the previous fiscal year. The tech giant has pledged to spend nearly $10 billion on CoreWeave’s services by the end of the decade, reflecting a deep integration of CoreWeave’s infrastructure into Microsoft’s AI strategy.
This substantial reliance underscores the importance of operational excellence and timely delivery in maintaining such critical partnerships.
CoreWeave’s Financial Growth & Challenges
In 2024, CoreWeave reported revenue of approximately $2 billion, a significant increase from $25 million in 2022. However, the company continues to face substantial losses and has accumulated significant debt. Despite these financial challenges, CoreWeave has secured substantial funding, including approximately $11 billion in debt and $2 billion in equity, led primarily by Blackstone, Magnetar Capital, and other major financial institutions.
The company’s rapid growth trajectory highlights both its potential and the financial hurdles it must navigate.
Dependency on Nvidia’s AI Chips
CoreWeave’s infrastructure heavily relies on Nvidia’s AI chips, owning around 300,000 of them. This dependency positions CoreWeave as a significant customer and partner of Nvidia, which holds over 5% of CoreWeave.
The strategic relationship with Nvidia is central to CoreWeave’s ability to deliver high-performance AI computing services, making the reliability of Nvidia’s technology crucial to CoreWeave’s operations.
Microsoft’s AI Infrastructure Shift
Microsoft’s decision to adjust its commitments to CoreWeave reflects its evolving AI strategy and the need for reliable infrastructure to support its AI initiatives. While scaling back certain agreements due to delivery issues, Microsoft remains committed to significant AI investments, including its substantial partnership with CoreWeave. This move underscores Microsoft’s focus on ensuring that its AI infrastructure partners can meet the high standards required to support its AI ambitions.
Conclusion
The recent developments involving Core Scientific, CoreWeave, and Microsoft highlight the intricate dynamics of partnerships in the rapidly evolving AI and high-performance computing sectors. Core Scientific’s share price decline following Microsoft’s reduced commitments to CoreWeave underscores the interconnectedness of these companies and the impact of operational challenges on market perceptions. As CoreWeave prepares for its IPO and continues to expand its infrastructure, addressing delivery and reliability issues will be crucial to maintaining and growing its strategic partnerships. For Microsoft, ensuring that its AI infrastructure partners can meet delivery expectations is essential to support its ambitious AI initiatives. These developments serve as a reminder of the importance of operational excellence and strategic alignment in the competitive landscape of AI infrastructure.
