Nebius: When Your Biggest Customer Becomes Your Biggest Competitor
02.07.2026 - 10:35:56 | boerse-global.de
Nebius Group is the picture of operational perfection: revenues soaring 684% year-over-year to $399 million in the first quarter, every GPU generation selling out the moment it goes live, and pricing power that lets management dictate terms. Yet the stock has been hammered, sliding to €197.70 at one point — a 12% drop in just seven days — and closing Wednesday at €201.35, down nearly 11% on the week. The reason lies not in the company’s performance, but in an emerging threat from its own most important partner.
Meta Platforms, which signed a cloud infrastructure partnership with Nebius worth up to $27 billion, is now building its own cloud. Under the working name "Meta Compute," the tech giant plans to sell excess AI computing capacity directly to external developers. That would turn a key customer into a direct rival, flooding the market with spare high-performance compute from a source that controls both supply and demand. The potential margin pressure on Nebius is immediate and severe, and the stock’s reaction reflects that fear.
The operational story remains spectacular. Nebius can barely keep up with demand: first-quarter revenue rose 75% sequentially to $399 million, and the company’s forward pipeline is at record levels. The annualized gain in the stock still stands at 366% over the past year, and year-to-date it is up 158%. But beneath the surface, the bears are circling. Short interest has swelled to 23% of the float — an unusually high figure for a triple-digit grower — signaling deep skepticism that the rally has overshot reality.
Should investors sell immediately? Or is it worth buying Nebius?
Critics point to the circular nature of the sector’s financing. Nvidia invests capital in Nebius; Nebius uses that money to buy Nvidia GPUs; Nvidia books the revenue as a sale. The underlying demand from end customers like Microsoft and Meta is real, but the blurring of organic growth and vendor-financed sales makes valuation treacherous. The stock’s annualized volatility of roughly 105% underscores just how knife-edged the debate has become.
The math of the expansion plan only intensifies the worry. Nebius has raised its 2026 capital expenditure budget to between $20 billion and $25 billion, while guiding for revenue in a range of just $3.0 billion to $3.4 billion. That is an infrastructure gamble of enormous proportions — a bet that the AI capex cycle will keep accelerating. If growth slows before capacity is filled, the financial strain will be brutal. For now, the market still values the company at over €58 billion, but the coming months will test how long investors are willing to fund a business whose spending so massively outstrips its sales.
Meta’s move adds an existential layer to that risk. If the tech giant begins selling its own GPU clusters to third parties, it could trigger a price war that undermines Nebius’s fat margins. Nebius would then have to prove that its own pipeline is robust enough to absorb the shock. For a company already walking a tightrope between explosive growth and crushing capital demands, the arrival of a powerful rival with inside knowledge of the market is the last thing it needs.
