Competitive Positioning: Nebius vs. CoreWeave

While Nebius has gained momentum, it faces stiff competition from CoreWeave, a larger player with 10 times more GPUs and exclusive access to Nvidia's cutting-edge hardwareCoreWeave vs. Nebius: Which AI Infrastructure Stock Is the Better Buy^[10]. CoreWeave's $30.1 billion contracted backlog and 207% year-over-year revenue growth (to $1.2 billion in Q2 2025)CoreWeave’s Q2 2025 Earnings Report^[11] highlight its dominance. However, CoreWeave's financials are a double-edged sword: $25 billion in debt and rising interest expenses (up to $267 million in Q2 2025)CoreWeave’s Financial Risks^[12] pose significant risks, particularly if client concentration (77% of 2024 revenue from top two clients) leads to volatility.

Nebius, by contrast, boasts a cleaner balance sheet and a diversified client strategy.

Risks and Realities

Despite its strengths, Nebius is not without vulnerabilities. The company is expected to report negative adjusted EBITDA for 2025Nebius’s EBITDA Outlook^[15], and its reliance on debt financing for capital expenditures could strain liquidity if interest rates remain elevated. Additionally, the AI infrastructure market is highly competitive, with new entrants and established players like Oracle and Amazon Web Services (AWS) vying for market shareArtificial Intelligence - Worldwide | Market Forecast^[16].

Microsoft's deal with Nebius also raises questions about the sustainability of such large contracts. While the five-year term provides visibility, the AI landscape could evolve rapidly, requiring Nebius to innovate beyond GPU capacity to maintain relevance.

Conclusion: A High-Risk, High-Reward Proposition

Nebius Group represents a compelling, albeit speculative, investment in the AI infrastructure boom. Its partnership with Microsoft validates its role in the ecosystem, while the explosive growth of AIaaS and GPU-as-a-Service markets offers a vast addressable opportunity. However, investors must weigh the company's unprofitable status, heavy capex requirements, and competitive pressures against its strategic advantages. For those with a long-term horizon and a tolerance for volatility, Nebius could deliver outsized returns as AI reshapes the global economy.
