The rapidly expanding artificial intelligence (AI) infrastructure sector sees CoreWeave and Nebius Group driving immense growth. While both are critical players, CoreWeave presents a stronger investment case with its robust backlog and attractive valuation, despite recent market fluctuations.
The race to build and provision the computational backbone for the artificial intelligence revolution is intensifying. At the forefront of this high-stakes game are two “neocloud” companies: CoreWeave (NASDAQ: CRWV) and Nebius Group (NASDAQ: NBIS). Both specialize in developing high-performance data centers tailored for AI workloads, which they then rent to hyperscalers, AI startups, and other enterprises demanding dedicated AI compute capacity.
This niche, yet rapidly expanding, segment of the tech market has propelled both companies to significant valuation jumps. CoreWeave, which made its initial public offering (IPO) in late March, initially saw its stock surge by 84% before experiencing a notable correction. Meanwhile, Nebius Group has witnessed an even more dramatic ascent, with its stock price soaring an impressive 231% this year. For investors eyeing the AI sector, the critical question remains: which of these high-growth contenders offers the better long-term value?
CoreWeave: A Deep Dive into its AI Dominance
CoreWeave’s market debut in late March marked the largest U.S. tech IPO since 2021, generating significant buzz. Although its stock price initially climbed and hit a peak on June 20, it has since retraced, losing over 60% of its value. This downturn was exacerbated by the company’s recent third-quarter results, which, despite reporting substantial year-over-year revenue growth of 134% to $1.36 billion, led to a slight reduction in its full-year revenue guidance to $5.1 billion from an earlier estimate of $5.25 billion, a detail confirmed by AOL Finance.
The adjustment in guidance was attributed to a temporary delay in data center capacity delivery from a third-party developer. CoreWeave has reassured investors that the impacted customer will maintain the total contract value, merely adjusting the delivery schedule. This suggests the issue is a short-term operational hiccup rather than a fundamental flaw in demand or strategy.
CoreWeave’s long-term growth narrative remains robust, underscored by its burgeoning revenue backlog. The company’s backlog surged from $15 billion a year ago to just under $56 billion by the end of the previous quarter, a nearly four-fold increase. This impressive expansion is a direct reflection of the escalating global demand for AI compute capacity. Major players like Meta Platforms and OpenAI are among the hyperscalers and AI firms that have inked substantial contracts with CoreWeave to secure this vital infrastructure, as reported by The Motley Fool.
To meet this demand, CoreWeave is aggressively expanding its infrastructure. In Q3 alone, it boosted its contracted data center power capacity by 600 megawatts (MW), reaching a total of 2.9 gigawatts. The company also brought 120 MW of new capacity online during the quarter, bringing its total active data center capacity to 590 MW. This rapid capacity deployment is crucial for converting its extensive backlog into realized revenue.
Furthermore, CoreWeave has successfully diversified its client base, now serving 10 large customers, many of whom have multiple contracts. This strategic diversification reduces reliance on any single client, enhancing the company’s stability and long-term resilience within the highly competitive AI infrastructure market.
Nebius Group: Rapid Expansion with Concentrated Growth
Just like CoreWeave, Nebius Group also operates at the cutting edge of AI infrastructure, attracting massive contracts from industry giants. While smaller in scale compared to CoreWeave, Nebius has demonstrated remarkable agility in scaling its operations through strategic deals. The company reported an astounding 355% year-over-year revenue growth in Q3, reaching $146 million.
Nebius’s growth trajectory is heavily influenced by a few high-value contracts. Notably, Microsoft awarded Nebius a deal valued between $17.4 billion and $19.4 billion in September to procure AI compute capacity over five years, according to AOL Finance. Similarly, Meta Platforms has committed to a five-year contract worth $3 billion. These agreements collectively contribute to Nebius’s substantial revenue backlog of over $20 billion.
To capitalize on these lucrative contracts, Nebius is accelerating its data center capacity expansion plans. The company has revised its target for contracted data center capacity, now aiming for 2.5 GW by the end of 2026, a significant increase from its earlier projection of 1 GW. Additionally, Nebius plans to boost its active data center capacity from an estimated 220 MW by the close of 2025 to a range of 800 MW to 1 GW by the end of 2026. These ambitious targets indicate a strong potential for continued rapid revenue growth, aligning with analyst expectations found on YCharts.
Valuation and Investor Outlook: CoreWeave’s Edge
Both CoreWeave and Nebius are compelling investment opportunities, poised to benefit immensely from the escalating demand for AI infrastructure. However, a crucial differentiator for investors lies in their respective valuations and underlying business structures.
CoreWeave currently trades at a significantly more attractive price-to-sales ratio, positioning it at a discount compared to the U.S. technology sector’s average P/S ratio of 8.4, a metric analyzed by The Motley Fool. This advantageous valuation, coupled with its much larger and more diversified revenue backlog of nearly $56 billion, provides a more compelling entry point for investors. CoreWeave’s broad customer base, encompassing 10 major clients with multiple contracts, mitigates concentration risk, a critical factor in volatile growth sectors.
In contrast, while Nebius exhibits explosive growth, its substantial backlog of over $20 billion is heavily concentrated with just two primary customers: Microsoft and Meta. This concentration, while indicative of strong partnerships, could expose Nebius to greater risk should one of these major clients alter their spending or strategic direction. Given these factors, CoreWeave’s current valuation and diversified growth profile offer a more prudent investment choice for those looking to capitalize on the AI compute boom, as detailed in financial analysis by The Motley Fool.
