In the competitive realm of AI infrastructure, Nebius Group emerges as the more appealing investment option for 2026, largely due to its profitable business model and manageable debt levels compared to CoreWeave.
Strong Revenue Growth and Profitability
Nebius Group has shown remarkable growth, with its revenue increasing by approximately 479% in its 2025 fiscal year, reaching around $529.8 million. This impressive trajectory has resulted in a net income of $101.7 million, yielding a positive net margin of 19.2%. In contrast, CoreWeave reported a staggering revenue of $5.1 billion but faced a significant net loss of $1.2 billion, leading to a negative net margin of 22.7%. While CoreWeave's revenue figures are striking, the difference in profitability metrics raises questions about its long-term sustainability.
Comparative Debt Profiles
Nebius wrapped up the 2025 fiscal year with around $4 billion in debt, reflecting a debt-to-equity ratio of approximately 1.1x. This metric suggests a balanced approach to using debt without excessive risk. Conversely, CoreWeave's financial strategy has resulted in over $20 billion in debt, with a substantially higher debt-to-equity ratio of 4.5x. This heavy reliance on debt raises concerns, especially as the company continues to aggressively expand its infrastructure.
Risk Assessment
CoreWeave's business model is fraught with risks, including high customer concentration—around 67% of its revenue comes from Microsoft—and a sole dependency on NVIDIA for GPU hardware. This reliance creates vulnerability to potential disruptions. Its operational risks are heightened by leasing third-party data centers, exposing it to risks such as power outages or security breaches.
In contrast, Nebius Group has diversified its customer base, serving various industries including healthcare and finance, which may help mitigate the impact of losing any single client. However, it still faces its own challenges, particularly in scaling its operations internationally and adapting to the fast-changing technology landscape.
Valuation Metrics
In terms of valuation, CoreWeave appears more attractively priced with a forward P/E ratio of 29.1x compared to Nebius’s lack of available earnings estimates. However, Nebius trades at a much higher price-to-sales (P/S) ratio of 89.6x versus CoreWeave’s 10.6x, reflecting market confidence in Nebius’s sustainable growth and profitability.
Market Outlook
Nebius reached a 52-week high of $233.73 as of mid-May 2026, indicating strong investor sentiment. Meanwhile, CoreWeave’s financial struggles and heavy debt load suggest a more vulnerable position in the market. While CoreWeave's extensive infrastructure expansion aligns with the surge in AI demand, the associated risks could overshadow potential returns.
Despite CoreWeave’s impressive top-line growth, Nebius Group’s profitability, lower debt levels, and broader industry applicability position it as the superior investment for 2026. Investors may find Nebius to be a more stable and resilient choice in the evolving AI infrastructure sector.
