A recent in-depth report provides a systematic comparison of the strategic differences and similarities between two prominent Neocloud companies, CoreWeave, Inc. and NEBIUS. According to the analysis, CoreWeave, Inc. has established a leadership position in the industry due to its larger scale, proven execution track record, and highly visible financing pathway. In contrast, NEBIUS is building differentiated optionality value through greater spot market flexibility, a diversified strategy targeting enterprise customers, and a more flexible capital structure.
The disparity in financial performance is stark. In 2025, CoreWeave, Inc. reported revenue of $51.3 billion, representing a 168% year-over-year increase, with EBITDA reaching $31 billion and a margin of 60%. NEBIUS reported revenue of only $5.3 billion, a 479% year-over-year increase, but posted an EBITDA loss of $65 million, resulting in a negative margin of -12%. However, the growth rates for both companies are impressive. CoreWeave, Inc.'s revenue is projected to grow to approximately $125 billion in 2026, while NEBIUS is expected to surge to around $33 billion, indicating both are on a hyper-growth trajectory.
A key differentiator for investors is the nature of their revenue streams. Over 98% of CoreWeave, Inc.'s business is tied to multi-year "take-or-pay" long-term contracts, providing strong revenue visibility. Conversely, NEBIUS has a higher exposure to the spot market, which could offer greater near-term pricing flexibility in an environment of rising GPU prices. Excluding contracts with Microsoft and Meta, approximately $550 million of NEBIUS's Annual Recurring Revenue (ARR) comes from on-demand/spot markets and shorter-term contracts. This provides significant repricing potential amid strong demand and constrained supply. Factors supporting near-term GPU pricing strength include robust demand, supply bottlenecks, memory price inflation, and a surge in token consumption driven by autonomous agents.
In the spot market exposure dynamic, NEBIUS holds an advantage and may benefit more from near-term GPU price increases. The aforementioned $550 million ARR is largely subject to repricing. In contrast, CoreWeave, Inc.'s long-term contracts lock in revenue visibility but sacrifice spot market elasticity. It is noted that memory price increases, deployment challenges, and rising compute consumption from autonomous agents are likely to sustain strong GPU pricing trends in the short term. If GPU prices continue to climb, NEBIUS could consistently outperform.
Regarding data center strategy, both CoreWeave, Inc. and NEBIUS employ a "hybrid" approach, combining co-location, build-to-suit, and self-built facilities, but their existing infrastructure differs significantly. CoreWeave, Inc. currently operates 43 data centers, predominantly using a co-location model, but is actively introducing self-build and joint venture models. NEBIUS already operates a 75MW self-built data center in Finland and has planned large-scale projects in the US. NEBIUS views self-built campuses as the long-term optimal solution for cost control and operational efficiency. Both companies utilize co-location for rapid expansion but plan to increase self-build ownership for better economics and control.
Power capacity is a core resource in the AI cloud competition. As of the end of 2025, CoreWeave, Inc. had secured 3.1GW of power capacity, with over 850MW active. NEBIUS had secured 2GW, with only 170MW active, meaning CoreWeave, Inc.'s active power is five times greater. Looking ahead, CoreWeave, Inc. aims for over 8GW of secured capacity by 2030, while NEBIUS targets 3GW by the end of 2026 and 5GW by 2030. The gap in annual capacity additions reflects CoreWeave, Inc.'s proven execution capability at scale, whereas NEBIUS's story is still in a relatively earlier stage.
Capital structures and financing strategies also differ markedly. To support massive capital expenditure, both require substantial ongoing funding. CoreWeave, Inc. relies heavily on a Delayed Draw Term Loan (DDTL) mechanism, having developed a mature asset-level debt financing system. Its total debt principal reached $21.6 billion by the end of 2025, with projections suggesting significant increases through 2028. NEBIUS started with a cleaner balance sheet, utilizing convertible notes, equity issuance, and customer prepayments for financing. Its recent $4.338 billion convertible note offering has bolstered liquidity. For 2026 capital expenditure, CoreWeave, Inc. guided for $30-35 billion, while NEBIUS guided for $16-20 billion. Both have received $2 billion in strategic investment from NVIDIA.
Customer concentration and market strategy reveal another contrast. CoreWeave, Inc.'s strategy prioritizes achieving maximum scale rapidly. Approximately two-thirds of its current revenue comes from Microsoft, with a similar proportion of ARR expected from Microsoft, OpenAI, and Meta combined by the end of 2026. This high concentration offers strong revenue visibility but carries concentration risk. NEBIUS's strategy focuses on selling AI cloud services to a broader base of enterprise customers and AI startups. While its current backlog is also concentrated, its anchor contracts with Microsoft and Meta are of high quality. A portion of the Meta contract provides a "remaining capacity backstop commitment," giving NEBIUS flexibility to serve smaller and less creditworthy clients. NEBIUS aims to grow its ARR from its core contracts and gradually diversify its customer base.
In terms of software stacks, both companies aim to be "full-stack AI infrastructure platforms" rather than mere GPU lessors. CoreWeave, Inc.'s software stack is more mature, particularly in infrastructure orchestration, observability, workload management, and storage. Its Object Storage business has surpassed $100 million in ARR. NEBIUS focuses on building a tightly integrated, secure AI cloud environment, emphasizing virtualization, tenant isolation, workload orchestration, and inference toolchains, aiming for a vertically integrated platform for enterprise clients. CoreWeave, Inc. leads in software maturity and platform breadth, while NEBIUS shows long-term potential with its differentiated, application-focused products.
Profitability profiles start from vastly different points but may converge. CoreWeave, Inc. already demonstrates strong EBITDA profitability (60.8% margin in 2025), though its adjusted EBIT margin is expected to face temporary compression due to timing differences between capital deployment and revenue recognition. NEBIUS is currently in a significant loss-making phase, attributed to inherited operational costs, drag from loss-making assets, and depreciation/interest pressures during rapid expansion. However, NEBIUS's EBITDA margin is projected to improve dramatically from -12.2% in 2025 to over 70% by 2028. If NEBIUS can realize the cost advantages of its self-built data centers and successfully transition to higher-margin enterprise clients, its long-term profit potential is significant.
Both companies face valuation challenges. A "Neutral" rating was assigned to each, with target prices below current trading levels, suggesting optimistic expectations are largely priced in. CoreWeave, Inc.'s primary risks include its high debt load and concentrated customer base. NEBIUS's core risks involve aggressive short-term revenue targets, an unproven profit record, and uncertainty surrounding its sales transformation towards a broader enterprise clientele. Shared potential risks include normalization of AI demand, in-sourcing of AI compute by major customers, and a shortening effective useful life of GPUs. For investors prioritizing scale and certainty, CoreWeave, Inc.'s execution and financial visibility are more appealing. For those seeking growth optionality and diversification, NEBIUS's spot market exposure and enterprise cloud strategy offer a differentiated investment thesis.
