CoreWeave (NASDAQ: CRWV) and Nebius Group N.V. (NASDAQ: NBIS) have emerged as two of the most closely watched names in the rapidly expanding AI infrastructure sector.
Both companies focus on providing high-performance GPU capacity for AI model training and inference workloads at scale.
Per a report from Fortune Business Insights, the global AI infrastructure market is projected to grow from $75.4 billion in 2026 to $497.98 billion by 2034, at a compound annual growth rate of 26.6%.
CoreWeave has built a significant competitive edge through its close relationship with NVIDIA (NASDAQ: NVDA), becoming the first AI cloud provider to complete the bring-up and full system-level validation of NVDA’s Vera Rubin NVL72 platform.
In January, NVIDIA increased its investment in CoreWeave to $2 billion, further cementing a partnership that gives CRWV preferential access to cutting-edge hardware.
CoreWeave has surpassed 3.5 GW of contracted power capacity, secured more than $20 billion in debt and equity financing, and grown its backlog to nearly $100 billion.
The company projects capital expenditures of $31 billion to $35 billion in 2026, reflecting aggressive capacity buildouts that continue to pressure near-term profitability.
CoreWeave also expects substantial interest expense of $650 million to $730 million in the second quarter alone, driven by rising debt used to fund its rapid expansion.
Nebius is scaling aggressively from its European base, increasing contracted power capacity from just over 2 GW to more than 3.5 GW within three months and targeting at least 4 GW by 2026.
The company announced a new Pennsylvania data center campus capable of supporting up to 1.2 GW of capacity, marking its second owned gigawatt-scale site in the United States.
Nebius reported its sales pipeline grew 3.5x quarter over quarter in the first quarter, with notable customers including Revolut, 1X Technologies, Sword Health, Rhoda, and monday.com.
In the first quarter, Nebius completed three strategic acquisitions, Tavily, Eigen AI, and Clarifai, strengthening its capabilities in inference optimization, agentic search, and software integration.
Nebius maintains a strong financial position with $9.3 billion in cash and more than $6 billion raised this year, including funding from NVIDIA and convertible debt offerings.
The company raised its 2026 capital expenditure guidance to $20 billion to $25 billion, reflecting expansion plans that increase capital intensity and execution risk heading into next year.
Over the past year, CRWV has declined 35.5% while NBIS has gained 455.9%, illustrating a stark divergence in market sentiment toward the two companies.
Both stocks trade at a premium valuation, with NBIS shares at a Price/Book ratio of 9.91x compared to CRWV’s 10.36x, and both carry a Value Score of F.
Analysts have significantly revised earnings estimates upward for NBIS for the current year, while the Zacks Consensus Estimate for CRWV’s earnings has been sharply revised downward over the past 60 days.
Both CRWV and NBIS currently carry a Zacks Rank of 3, or Hold, reflecting balanced but cautious outlooks from the research community.
For investors seeking a more established AI infrastructure play, CoreWeave offers proven execution and strategic NVIDIA access, while Nebius presents higher potential upside within an underpenetrated European cloud market.
A balanced approach may involve holding both stocks, with CoreWeave serving as the lower-risk core position and Nebius acting as the higher-growth, longer-horizon opportunity.
