Nebius's $46 Billion AI Bet: The Power Play That Could Make or Break the Stock

Nebius shares fell 11% on jobs data, but the company's $46B backlog and aggressive power deals highlight the infrastructure race powering AI.

The stock market punished Nebius last week, but the company's real battle isn't fought on trading screens. It's waged in the physical world, where securing a single megawatt can determine the winner in the AI arms race. On Friday, the shares tumbled 11.45% to €197.90, having hit an all-time high of €242.95 just days earlier. That 18% round-trip from the record looks dramatic, but it masks a deeper narrative about the infrastructure challenges underpinning the entire artificial intelligence boom.

Power has become the primary bottleneck for AI cloud providers. Nebius's infrastructure chief recently described electricity as the single biggest hurdle to scaling, and the company is acting on that conviction. In May, it struck a deal with Bloom Energy to deploy fuel cells that bypass traditional grid connections entirely. These modular units can be installed far faster than conventional power plants—the first project alone will deliver 328 megawatts this year—and require fewer permits. In an industry where months of delay mean lost contracts, that speed translates directly into revenue.

The aggressive push for power is a response to overwhelming demand. Nebius reported first-quarter revenue of $399 million, a 684% surge from a year earlier, with servers completely sold out and electricity fully allocated. Management says four customers are typically competing for every new graphics processor. The company's contracted power needs have already swelled to over 3.5 gigawatts, with a target of 4 gigawatts by year-end, and a new site in Pennsylvania will contribute up to 1.2 gigawatts.

These aren't speculative builds. Nebius has locked in customer contracts worth $46 billion, with Meta committing $27 billion and Microsoft adding $17 billion. Nvidia itself has weighed in with a $2 billion investment. The order backlog provides the financing clarity for Nebius's capital expenditure budget, which has been raised to as much as $25 billion. Management has reaffirmed a multi-billion-dollar revenue goal for 2026 alongside an operating margin target of roughly 40%.

Yet even as the operational story strengthens, the stock has been hit by a convergence of headwinds. The proximate cause was Friday's US jobs report, which showed 172,000 new positions—double the consensus forecast—and crushed hopes for imminent rate cuts. Yields on US Treasuries spiked, and richly valued tech names took the brunt. Nebius's annualized volatility of 136% amplifies every macro tremor, and the shares have now slipped well below their 50-day moving average of €149.41, though they remain comfortably above the long-term average of €101.77.

Adding to the unease, a cluster of insider sales coincided with the recent peak. Chief technology officer Danila Shtan, CFO Sanchez Maria Del Dado Alonso, and sales chief Marc Boroditsky all unloaded stock, as did Nvidia director Mark Stevens. The breadth of the cashing out among key insiders has raised eyebrows, even if the timing may be tax-related or part of routine portfolio management.

Analysts are split on what lies ahead. Citi maintains a price target as high as $287, while DA Davidson has downgraded Nebius to "Neutral" with a $250 target. Technically, the relative strength index at 56.2 suggests the shares are no longer overbought after the pullback. With a market capitalisation of roughly €55 billion, the stock has already priced in a transition from speculative AI play to something closer to a utility-grade infrastructure provider.

The swing in sentiment does not change the fundamental wager. Nebius is racing to lock down every available watt before rivals can, and its contracts with the industry's biggest names provide a financial cushion that pure-play cloud companies often lack. The real test will come over the next two years, as massive data centres in Missouri and Pennsylvania begin to go live. If the company delivers its planned capacity on schedule, the current stock volatility will look like a footnote. If the grid remains the bottleneck, no amount of fuel-cell engineering will salvage the valuation.
