Nebius: The $20 Billion Build-Out That Could Make or Break the AI Darling

Nebius plans a $16-20B AI data center build-out for a $12B Meta deal, but Wolfe Research questions its financing. Shares are up 94% YTD on $50B backlog.

The race to build AI infrastructure is a capital-intensive gamble, and Nebius Group is betting the house. To fulfill a massive $12 billion fixed-capacity contract with Meta, plus billions more in options, the company plans to spend between $16 and $20 billion this year alone. This staggering outlay dwarfs its 2025 revenue of $530 million, highlighting the high-stakes financing challenge at the core of its explosive growth story.

Wall Street remains largely enamored with the narrative. Of the 14 analysts tracked by Investing.com, 11 recommend buying the stock, with an average price target of $170 and a high target reaching $291. The share price itself reflects this optimism, having surged approximately 94% year-to-date and trading just 8% below its April peak. The company’s backlog is formidable, with nearly $50 billion in contracted revenue secured for the period from 2027 to 2031.

However, a lone dissenting voice urges caution. Wolfe Research initiated coverage on April 16 with a "Peer Perform" rating, effectively a hold. Analyst Arseniy Matovich places a fair value range on the stock between $80 and $170, derived from 4 to 8 times estimated 2027 EBITDA. The lower bound of that range sits nearly 50% below the recent price of around $158 dollars. Wolfe acknowledges the robust demand, evidenced by deals with Meta and Microsoft, but questions whether Nebius can actually finance and execute its ambitious construction plans.

The scale of the build-out is unprecedented. Nebius aims to expand its data center capacity from 170 megawatts at the end of 2025 to between 800 megawatts and 1 gigawatt by the close of 2026. This requires advancing construction on nine new facilities, including a planned AI factory in Finland slated to come online by 2027. To fund this sprint, the company has already raised capital aggressively, placing $8.3 billion in bonds this March and taking on approximately $4.3 billion through convertible notes.

Financing the growth is only half the battle. Technologically, Nebius is pursuing an integrated approach, offering everything from data center design to software optimization. It is also positioning itself at the forefront of new hardware, being among the first cloud providers—alongside AWS, Google Cloud, Microsoft, and rival CoreWeave—to deploy Nvidia’s new Vera Rubin architecture. Nvidia’s recent $2 billion direct investment in Nebius underscores this close partnership.

Management projects that a successful expansion will translate into 2026 revenue of $3 to $3.4 billion, with an adjusted EBITDA margin nearing 40%. Yet, for all the contracted future revenue, profits remain elusive today. The entire neo-cloud sector, including CoreWeave which saw revenue jump 168% last year, currently benefits from a scarcity of high-performance chips. A long-term risk looms: once Nvidia’s supply constraints ease, compute power could become a commodity, and mega-customers like Meta are already developing their own AI accelerators to reduce external dependence.

The coming weeks will provide a critical test. When Nebius reports its first-quarter 2026 results in late April, investors will scrutinize whether the ambitious plans are translating into tangible execution. The multi-billion dollar backlog only creates value if the infrastructure is delivered on time and the new hardware performs. For now, the market believes the growth story. The quarterly numbers will determine if Wolfe Research’s skepticism remains an outlier or becomes a prevailing view.
