Nebius Has $50 Billion in Backlog and a $2.6 Billion Fuel Cell Bet — Now It Must Deliver

Nebius draws divergent analyst views as $50B order backlog from Meta, Microsoft drives 684% revenue surge; power deal with Bloom Energy adds competitive edge.

The AI infrastructure gold rush has produced a curious split on Wall Street. Nebius, the Amsterdam-based cloud provider that saw its shares trade around $215 on Friday, is simultaneously winning bullish endorsements from Citigroup at $287 and a cautious "Neutral" from DA Davidson at $250. The divergence captures a tension at the heart of the stock: how much of a 684% revenue surge and a near-$50 billion order book is already priced in?

Citigroup holds the highest price target among analysts at $287, while Citizens JMP sits at $270 and the Seeking Alpha consensus points to $256.91 — implying roughly 20% upside from current levels. DA Davidson's Gil Luria, who downgraded to Neutral after the post-earnings rally, acknowledges strong execution and spending discipline but warns the premium valuation leaves little margin for error.

The Backlog That Defines the Story

What makes Nebius difficult to ignore is the sheer scale of its contracted pipeline. The company's order backlog is closing in on $50 billion, anchored by a multi-year commitment from Meta Platforms worth $27 billion. Microsoft accounts for up to $19.4 billion in pledges, and Nvidia has chipped in a $2 billion strategic investment. Together, these hyperscaler relationships bind Nebius tightly into the AI ecosystem — and set the stage for a massive revenue inflection.

That inflection hits hardest in the second half of 2026, when Nebius is scheduled to start delivering cloud capacity to Meta and Microsoft. Until then, revenue comes largely from existing operations: first-quarter 2026 sales hit $399 million, up 684% from $50.9 million a year earlier, powered by an 841% jump in Cloud AI revenue to $389.7 million. The adjusted EBITDA margin improved to 32.5%, and annualized recurring revenue climbed 54% to $1.92 billion.

Power as a Competitive Moat

Behind the revenue numbers lies a less obvious but equally critical advantage: electricity. Nebius has signed a 10-year agreement with Bloom Energy to deploy solid-oxide fuel cells that generate power on-site, bypassing overloaded grids and slow permitting processes. The first U.S. project, expected to go live later in 2026, will deliver 328 megawatts of capacity. The contract is worth up to $2.6 billion over its full term.

The deal gives Nebius a strategic edge in a market where hyperscalers are desperate for reliable, low-carbon energy. It also supports the company's build-out target: Nebius has already secured more than 3.5 gigawatts of contracted capacity, above its year-end goal of 3 gigawatts, and now aims for over 4 gigawatts by December. More than 75% of that total is expected to be owned infrastructure, giving Nebius tighter control over costs and operations.

Expansion into Pennsylvania — with a site capable of 1.2 gigawatts — is slated to come online in phases starting in 2027, complementing an existing 1.2-gigawatt AI factory in Independence, Missouri.

Capital Discipline vs. Aggressive Leverage

Nebius's financial structure sets it apart from rival CoreWeave, which exited 2025 with more than $20 billion in debt. Nebius carried roughly $4 billion in debt against $3.7 billion in cash, and in April it raised $4.3375 billion through a private placement of convertible notes — the larger $2.5875 billion tranche maturing in 2031 and the $1.75 billion tranche in 2033. While the convertible notes carry dilution risk, the overall leverage is far more controlled.

The company also has a $2 billion strategic investment from Nvidia, reinforcing its role as a key infrastructure partner.

From GPU Rental to Full-Stack AI

Nebius is positioning itself as more than a cloud GPU renter. It is building a full-stack AI infrastructure business, offering managed software for training, inference, education technology, and robotics. The planned acquisition of Eigen AI — for up to $98 million in cash and 3.8 million Class A shares, with vesting conditions for key personnel — strengthens the inference and model-optimization side of the platform. The logic: as AI moves from training spurs to steady-state production workloads, recurring revenue will matter more than one-off compute peaks.

The company's asset productivity metric — $0.941 million per megawatt of active capacity in the first quarter — will be closely watched as a measure of whether all that infrastructure is being monetized efficiently.

The 2026 Hurdle

Nebius management has set ambitious targets for the year: revenue between $3.0 billion and $3.4 billion, an adjusted EBITDA margin of roughly 40%, and annualized recurring revenue of $7 billion to $9 billion. To achieve that, the company plans to invest $20 billion to $25 billion, funded in part by hyperscaler contracts.

Execution risk is real. Delays in bringing new capacity online or in ramping deliveries to Meta and Microsoft would not only postpone revenue but also pressure a stock that already trades near peak expectations. When Nebius shares touched $215 on May 24, the market was effectively betting that the company can deliver on its blockbuster backlog — and that the fuel cell bet will keep the lights on when it does.
