It took a single Bloomberg headline to wipe roughly 17% off Nebius’s market value in early July, and a full week of trading to claw back a fraction of the loss. By Friday, the stock had recovered 2.02% to close at €193.00, but the episode exposed a structural vulnerability that no amount of quarterly growth can erase: the company’s largest customer, Meta Platforms, is now weighing a move that would make it a direct competitor. The annualized 30-day volatility of 99.24% — among the highest for any large-cap technology stock — suggests the market is pricing in something far more fundamental than short-term noise.
The sell-off was triggered by reports that Meta is exploring the sale of excess GPU computing capacity, potentially undercutting dedicated infrastructure providers like Nebius that have built their business model around stable, long-term rental contracts. Nebius’s dependence on a handful of hyperscalers is acute: the bulk of its order backlog comes from a single $27 billion, five-year agreement with Meta, split into $12 billion in committed capacity and $15 billion in optional capacity, with another large chunk tied to Microsoft. That concentration leaves the company extremely exposed to any strategic pivot by either partner. Should Meta begin offering spare compute at marginal cost to cover its own depreciation, the pricing power that underpins Nebius’s capital-intensive model would evaporate.
The company’s management has pushed back, arguing that global demand for AI compute continues to outstrip supply. Roughly four to five customers line up for every new GPU cluster that comes online, it says, and the structural shortage insulates Nebius from shifts in any single player’s strategy. That line of reasoning found support from research firm SemiAnalysis, which dismissed the panic as overblown, noting that Meta’s own AI ambitions are still growing and will require additional external infrastructure partners. Roth Capital echoed the sentiment, calling the broader neocloud sell-off excessive. Nebius has also sought to diversify its supply chain: a strategic partnership with Nvidia, backed by a $2 billion investment, secures preferred access to next-generation hardware such as the Vera-Rubin platform, reducing reliance on Meta-supplied chips.
Should investors sell immediately? Or is it worth buying Nebius?
The operational numbers offer some backing for that optimistic view. Nebius reported that its adjusted EBITDA margin in AI cloud nearly doubled quarter-on-quarter to 45% in the first quarter, with management guiding for roughly 40% for the full year — gains driven by cost control rather than pricing leverage. Revenue has accelerated sharply: a year ago, the company posted just $105 million in second-quarter revenue; by the fourth quarter, its annualized run rate had hit $1.25 billion. For fiscal 2026, Nebius expects turnover to exceed $3 billion, with a potential further doubling in 2027. To support that expansion, it recently partnered with fuel-cell maker Bloom Energy to secure additional power capacity for its data centers.
On a technical level, the stock remains in a peculiar twilight zone. Friday’s close of €193.00 sits less than 2% below the 50-day moving average of €196.93, while the 200-day moving average of €117.87 lies roughly 64% lower — a chasm that underscores how far and how fast the shares have risen over the past twelve months. The relative strength index of 46.6 points to a market that is neither euphoric nor panicked, simply indecisive. Over the trailing twelve months, the stock has gained 384.92%, and from its 52-week low of €38.00, it has surged more than 400%. Yet it remains 26.05% below the all-time high of €261.00 recorded on June 22 — the same day Nebius joined the Nasdaq-100.
The real question, however, is not whether Nebius can grow revenue or widen margins. It is whether the entire neocloud business model — built on long-term rental agreements with the very hyperscalers that could one day cut those tenants out — can survive the logical endpoint of its own success. A market capitalisation of €48.11 billion has been erected on the assumption that GPU hunger will trump every warning signal, including the most alarming one: that the industry’s biggest customer may become its most formidable rival. Until that uncertainty is resolved with hard numbers rather than headlines, the 99% annualised volatility that surrounds Nebius looks less like a market anomaly and more like the precise price of genuine doubt.
