Nebius Shares Hit $244.05 Record as $25 Billion Capex Plan Raises Funding Questions

Nebius stock stormed to an all-time high of $244.05 on Monday, capping a blistering run that has left many analyst price targets in the dust. The AI-cloud infrastructure company now commands a market capitalization of roughly $59.17 billion — a valuation that hinges not on past earnings but on the company's ability to execute an audacious expansion blueprint.

The rally has been relentless. On a year-to-date basis, shares have surged 176%, and over the past twelve months the gain stands at roughly 529%. Even after a slight pullback from the peak, the stock trades near $231, still well above the 52-week high of $233.73 cited before Monday's new milestone.

Q1 Numbers Fuel the Momentum

The first quarter provided the fundamental spark. Nebius reported revenue of $399 million, crushing the analyst consensus of $375 million. That represents a 684% jump from the prior year and a 75% sequential increase — a growth rate that is almost unheard of in the cloud-infrastructure space. The annualized run-rate revenue hit $1.92 billion at the end of March, up from $1.25 billion three months earlier.

Equally striking, the adjusted EBITDA swung to a positive $129.5 million from a loss of $53.7 million in the year-ago period. The loss per share came in at $0.23, dramatically better than the consensus estimate of a $0.77 loss. The AI-cloud business now accounts for 98% of total group revenue.

Should investors sell immediately? Or is it worth buying Nebius?

Management is targeting an annualized run-rate of $7 billion to $9 billion by the end of 2026 — a goal that looks increasingly plausible given that capacity is already sold out and demand commitments extend into 2027.

A Pivotal Week on the Conference Circuit

The timing of the all-time high could hardly be more charged. On Wednesday, June 3, co-founder and Chief Business Officer Roman Chernin is scheduled to appear at the BofA Securities Global Technology Conference for a fireside chat at 4:20 p.m. EDT. The event kicks off a marathon of investor engagement: Nebius will serve as a platinum sponsor at a US AI event on June 5, partner with NVIDIA at the Geektime Code in Tel Aviv on June 8, and host its own "Nebius Inflection: AI Expert Forum" in San Francisco on June 9.

Every word from management will be scrutinized for clues on capacity expansion, power agreements, and financing. The market wants to know whether the company can deliver the operational milestones needed to justify its elevated multiple.

The $25 Billion Capex Conundrum

Nebius ratcheted up its 2026 capital expenditure forecast to a range of $20 billion to $25 billion, a staggering commitment for a company that, until recently, was burning cash. The spending is directed at building out specialized AI clusters — data centers packed with GPUs, energy infrastructure, and short-iteration development cycles tailored for training complex models.

A key part of that strategy involves power. Nebius has partnered with Bloom Energy to deploy 328 megawatts of fuel-cell capacity for its AI data centers, ensuring reliable electricity for next-generation GPU clusters.

But the capex plan comes with a financing gap. Management indicated that an additional $4 billion to $5 billion in funding will be required to meet the 2026 targets. That could mean a capital increase, which would dilute existing shareholders and potentially dampen the stock's near-term momentum.

The company ended the quarter with $3.68 billion in cash and total assets of $12.4 billion, giving it some buffer. Vertically, it is on track to secure over four gigawatts of contracted capacity by year-end, implying a potential annualized revenue run-rate of $36 billion — far above current targets.

Insider Sales Cast a Shadow

While institutional interest remains robust — Foundations Investment Advisors boosted its position by 130% in the latest period — insider selling has been conspicuous. CEO Arkadiy Volozh sold 33,358 shares in April at an average price of $103.73, reducing his stake by 3.7%. Director Elena Bunina offloaded 10,894 shares in May at $206.87, cutting her holding by over 50%. Andrey Korolenko sold 500,000 shares at $203.24.

Combined, insider disposals over the past three months amount to approximately $123.5 million. Rovida Investment Management, a major institutional holder, trimmed its position by 16.6% but still holds Nebius as its largest single holding at 20.8%.

Nebius at a turning point? This analysis reveals what investors need to know now.

The selling does not necessarily signal a lack of confidence — insiders often diversify — but it adds a note of caution at a time when the stock is trading near record levels and the capex bill is mounting.

Acquisitions Build Out the Platform

Nebius has been busy expanding its technological footprint through M&A. The company announced the acquisition of Eigen AI, a developer of inference and model-optimization tools, for a mix of cash and Class A shares valued at roughly $643 million. The Eigen AI team, which includes researchers behind widely used optimization techniques, will establish an engineering and research hub in the San Francisco Bay Area.

Together with the earlier Clarifai acquisition, which focuses on system-level optimization, Nebius is assembling an end-to-end infrastructure stack capable of running complex AI models reliably in production.

Analyst Targets Play Catch-Up

Wall Street is scrambling to keep pace with the stock. The consensus rating is a "Moderate Buy," with price targets ranging from $144 (Morgan Stanley) to $270 (Citizens JMP). Bank of America recently lifted its target to $240 and reiterated its "Buy" rating, noting that the Q1 results demonstrated consistent execution amid strong demand and backlog growth. Compass Point sits at $260, while Goldman Sachs maintains a "Buy" with a $205 target — now well below the current market price.

The stark dispersion in targets underscores how quickly Nebius has outrun conventional valuation models. The stock's next leg will depend on whether the company can convert its ambitious capex plan into revenue without hiccups — and whether it can secure the financing to do so without spooking shareholders.
