Navigating the AI Cloud Landscape: A Tale of Two Companies
Understanding the Core Offerings: CoreWeave's Scale vs. Nebius' Innovation
Both Nebius Group and CoreWeave are pivotal in providing advanced cloud infrastructure essential for the development and deployment of artificial intelligence models. CoreWeave has achieved rapid expansion through a strategy involving leased infrastructure, substantial client agreements, and considerable debt financing. In contrast, Nebius, while smaller in scale, distinguishes itself by independently crafting its cloud software, storage solutions, networking capabilities, and tools for workload management.
Examining Revenue Trajectories and Market Presence
The superior investment opportunity hinges on whether CoreWeave's impressive scale and robust order book can outweigh its substantial financial commitments, or if Nebius can leverage its healthier financial standing to generate enhanced shareholder value. CoreWeave reported revenues nearing $2.1 billion in the first quarter, marking a 112% increase year-over-year. The company also boasts over 1 gigawatt of operational power capacity across its data centers. This indicates CoreWeave's significant current operational footprint and clear future revenue streams.
Unpacking CoreWeave's Financial and Operational Footprint
CoreWeave concluded the first quarter with an enormous revenue backlog of $99.4 billion. These figures not only highlight its considerable operational capacity but also provide strong assurances regarding its future revenue prospects. However, a large portion of this backlog will only translate into actual revenue once the company successfully delivers the committed computing power and makes these services accessible to its clientele.
Nebius' Explosive Growth and Strategic Client Engagements
Nebius, despite being a newer entrant, witnessed an astounding 684% year-over-year revenue growth in the first quarter, reaching $399 million. The company has also secured access to more than 4 gigawatts of power for its expanding data center operations. Nevertheless, a significant portion of this future capacity is still under construction and awaits activation. Nebius has dramatically increased its commercial pipeline generation, achieving 3.5 times the previous quarter's volume and securing major customer agreements. Notably, Microsoft has committed to a payment of up to $17.4 billion through 2031, contingent on Nebius installing the agreed-upon GPU systems and maintaining their availability. Microsoft also has the option to acquire an additional $2 billion in services or capacity, potentially increasing the total contract value to approximately $19.4 billion. Furthermore, Meta Platforms has agreed to a $12 billion purchase of dedicated capacity over the next five years, with an additional requirement to purchase up to $15 billion in capacity if Nebius fails to secure other clients for specified resources. These substantial agreements mitigate the risk of Nebius developing costly data centers without sufficient customer demand.
Analyzing the Financial Pressures and Investment Outlook
CoreWeave's adjusted EBITDA margin of 56% appears strong, but its adjusted operating margin was a mere 1% after accounting for depreciation and amortization. Its expansion, heavily reliant on debt, led to $536 million in net interest expenses, resulting in a net loss of $740 million. By the end of the first quarter of 2026, CoreWeave carried $25.1 billion in debt and $10.1 billion in operating lease liabilities. Consequently, a significant portion of CoreWeave's revenue is currently consumed by depreciation, interest payments, and long-term lease obligations, leaving less for shareholders. Nebius, during the first quarter, invested approximately $2.47 billion in tangible and intangible assets. While its operating cash flow reached $2.3 billion, this figure includes a $3.2 billion increase in deferred revenue, primarily reflecting customer prepayments for future services. Although these prepayments facilitate expansion, they do not represent recurring free cash flow. Currently, CoreWeave operates more efficiently. However, Nebius' lower financial leverage and its emphasis on owning its data centers could potentially yield greater long-term returns for investors. Therefore, Nebius seems to be the more promising stock, though investors should closely monitor its ability to deploy new capacity without incurring excessive debt or shareholder dilution.
