Nebius Faces a Rare Reckoning: Explosive Growth Meets a Valuation Ceiling

Despite $27B Meta contract, $19.4B Microsoft deal, and Jensen Huang's $2B bet, Nebius shares slip 8% amid valuation concerns and massive capex plans.

Nebius has everything a growth stock could want: a $27 billion contract with Meta, a $19.4 billion deal with Microsoft, and a $2 billion personal investment from Nvidia CEO Jensen Huang, who hailed the company as a "world-class AI cloud provider" at Computex 2026 in Taiwan. Yet the shares have slipped roughly 8% from their 52-week high of €242.95 set on June 2, settling at €224.35 on Thursday with a 3.39% gain. The disconnect between blockbuster demand and a pullback in price encapsulates a deepening debate over how much of the future is already baked in.

Revenue is exploding. First-quarter 2026 sales hit $399 million, a 684% surge year-over-year, with net profit of $621 million and an adjusted EBITDA margin of 45%. Analysts had braced for a loss. The annualized revenue run rate stood at $1.92 billion at the end of March, and management is gunning for $7 to $9 billion by year-end. By 2027, Wall Street forecasts top-line growth to more than $10.6 billion, up from $534 million in 2025. For all that promise, the stock's valuation already reflects an aggressive premium — and that has prompted a rare note of caution.

BNP Paribas initiated coverage on Nebius on June 2 with a "Neutral" rating and a $255 price target, pointing to limited upside relative to the forward revenue outlook. The call came shortly after DA Davidson downgraded the stock from "Buy" to "Neutral" while keeping its target at $250. Both firms praise Nebius's operational execution — particularly its 25% stake in ClickHouse — but see the share price as having run ahead of fundamentals. DA Davidson flags a valuation premium of roughly 30% versus the contracted backlog. The broader analyst consensus remains bullish: 16 analysts average a "Buy" with a mean target of $238.86, a figure now below the current euro-denominated price after currency conversion. Citigroup is the most optimist, lifting its target to $287, while Citizens JMP sits at $270 and Northland at $248.

The funding picture adds another layer of tension. Nebius plans to invest between $20 billion and $25 billion in 2026, requiring an additional $4 to $5 billion beyond its existing resources. At the end of March, the company held $9.3 billion in cash, up from $3.68 billion at year-end 2025. Some of that is already committed to a new AI data center complex in Pennsylvania, where land and power capacity have been secured. The bigger buildout is in Independence, Missouri, where a gigawatt-scale AI factory spanning 400 acres is under construction, set to generate 1,200 construction jobs. The Nvidia partnership is meant to help Nebius reach over five gigawatts of total capacity by 2030.

Meta's contract alone is worth up to $27 billion. The structure splits into $12 billion for dedicated GPU capacity and $15 billion for capacity that Nebius can sell to other customers if Meta does not use it. The Microsoft deal adds another $19.4 billion. Both are slated to ramp during the second half of this year, which makes the next six months the real test of whether Nebius can execute at scale without running into financing or construction delays.

Institutional appetite has been voracious. Leopold Aschenbrenner's Situational Awareness hedge fund now holds more than 12.4 million shares, valued at roughly $3.3 billion. Geode Capital Management increased its position by more than 1,000% in the last quarter. At the same time, short sellers have built a substantial bet against the stock: 21% of the free float, or more than 45 million shares, is sold short. That creates a double-edged dynamic. Positive execution news could trigger a squeeze; any hiccup in the capacity ramp could feed a violent unwind.

Technically, the stock remains stretched. The RSI sits at 68, approaching overbought territory, while the 30-day annualized volatility is a staggering 134%. The share price is more than 120% above its 200-day moving average and well above the 50-day average of €147.49. Year-to-date, gains stand at 193.27%, and the twelve-month return is 548.41%. The momentum is unmistakable — but so is the narrowing gap between the extraordinary growth narrative and the price investors now have to pay for it.
