Deals with Meta Platforms and Microsoft could give Nebius billions of dollars in revenue visibility and financing flexibility.
Nebius is evolving beyond simply renting AI computing power to its customers; now, it's offering a broader full-stack AI platform.
Chipmaker Nvidia (NASDAQ: NVDA) remains the poster child of the artificial intelligence (AI) revolution, and even from its lofty perch as the world's largest company, it has gained around 20% so far in 2026. However, another AI stock has delivered far stronger returns: Shares of Nebius (NASDAQ: NBIS), a fast-growing data center infrastructure player, have surged by almost 143% over the same period.

Nvidia also appears confident about Nebius' growth prospects. In March 2026, it announced a strategic partnership and agreed to invest $2 billion in Nebius for an approximately 8.3% ownership stake in the company. Under this partnership, Nvidia will provide the AI processors that will allow Nebius to deploy more than 5 gigawatts of data center capacity by 2030.
Nebius is focused on building data center infrastructure that's optimized for AI training, inference (running AI models in real time), and emerging agentic AI workloads (in which AI systems autonomously perform multistep tasks).
The company's most recent financial report highlights its business momentum. In the first quarter, revenues surged 684% year over year to $399 million. Nebius' AI business performed even better, with revenue growing by 841% year over year to $390 million, accounting for 98% of total sales. The AI business exited the first quarter with annualized run rate revenue (an annualized projection based on its latest quarterly revenue) of $1.9 billion, up by more than 50% sequentially. Management now expects revenues of between $3 billion and $3.4 billion and an adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) margin of nearly 40% in 2026.
Nebius sold out its available data center capacity in the first quarter, with demand continuing to exceed supply. That imbalance is giving the company significant pricing power.
Nebius' growing customer base is another major strength. Meta Platforms and Microsoft are major clients. The company's recently expanded deal with Meta Platforms is valued at $27 billion over five years and could become even more valuable if demand for AI processing capacity remains strong. The company's AI infrastructure deal with Microsoft is worth $17.4 billion over five years. Nebius also remains on schedule with its Microsoft-related capacity commitments. Management notes that both deals could give the company access to billions of dollars in financing at attractive rates to expand its cloud infrastructure.
Nebius' clients also include Revolut, Monday.com, and robotics company 1X Technologies. It is seeing growing interest from industries such as manufacturing, pharmaceuticals, heavy equipment, and energy. Customers are increasingly making upfront payments to Nebius to secure scarce AI computing capacity.
Nebius is also expanding beyond simply renting AI computing power. The company has acquired Tavily, Clarifai, and Eigen AI to expand its presence into faster-growing areas such as AI inference and agentic AI. It's aiming to position itself as a full-stack AI platform, which could help it deepen customer relationships.
However, certain risks cannot be ignored. Nebius raised its 2026 capital expenditure forecast to between $20 billion and $25 billion, up from its prior estimated range of $16 billion to $20 billion. That makes it a riskier investment than Nvidia, especially since it may need to raise more funds to sustain the pace of its build-out. In line with that, it may have to sell more stock (and dilute existing investors) -- and leadership has already set up an "at the market" program that would allow it to sell up to 25 million new shares. However, on the Q1 conference call, management said it hasn't made use of that fundraising option yet.
But with $9.3 billion in cash, major hyperscaler contracts, and explosive growth, Nebius could still prove a smart buy in 2026.

Four leading AI models discuss this article
"Nebius' capex-to-revenue ratio above 6x in 2026 creates unsustainable funding pressure that the article understates relative to Nvidia's asset-light model."
Nebius' Q1 results show AI revenue at a $1.9B annualized run rate with sold-out capacity and $44.4B in combined Meta/Microsoft contracts, yet the revised $20-25B 2026 capex target dwarfs the $3-3.4B revenue guide. With only $9.3B cash and an ATM program for up to 25M shares already authorized, the company faces a multi-year funding gap that Nvidia's $2B investment only partially addresses. The shift into full-stack AI via acquisitions adds integration and margin risk at the exact moment hyperscaler pricing power may peak.
The $27B Meta and $17.4B Microsoft deals explicitly include attractive-rate financing access that could cover most of the capex without immediate dilution, while 98% AI mix and 40% EBITDA margins suggest cash flow will ramp faster than modeled.
"Nebius is executing a high-leverage capex bet that only pencils if GPU scarcity persists and hyperscaler demand remains inelastic — both assumptions are increasingly fragile."
Nebius' 143% YTD return and 684% revenue growth look spectacular until you stress-test the unit economics. Management raised capex guidance to $20-25B annually while targeting 40% EBITDA margins by 2026 — that's a $12-14B EBITDA target against $25B in spend. The math only works if utilization stays near 100% and pricing holds. The $27B Meta deal and $17.4B Microsoft deal provide revenue visibility, but both are multi-year contracts signed when GPU scarcity was acute. If supply normalizes or demand softens, Nebius faces margin compression while carrying massive debt-financed infrastructure. The 'at the market' equity program signals management knows dilution is likely.
The article frames Nebius as a full-stack AI platform play, but it's still fundamentally a commodity data center operator competing on utilization and capex efficiency — not defensible IP. Nvidia's 20% gain reflects sustainable moat; Nebius' 143% could be speculative froth ahead of a capex reality check.
"Nebius is essentially a leveraged bet on hyperscaler infrastructure spending that faces extreme dilution risk if the $25B capex target outpaces free cash flow."
Nebius (NBIS) is currently trading on the 'picks and shovels' narrative, but investors are ignoring the massive execution risk inherent in their $20B-$25B capital expenditure guidance. While the 684% revenue growth is eye-catching, it is heavily reliant on massive upfront payments from hyperscalers like Meta and Microsoft, which essentially turns Nebius into a balance-sheet-heavy utility rather than a high-margin software play. The pivot to a 'full-stack' platform via acquisitions like Tavily is a defensive move to avoid commoditization. If the AI capex cycle cools or if these hyperscalers decide to bring more infrastructure in-house, Nebius’s massive debt-funding requirements could lead to severe shareholder dilution.
The massive upfront payments from Microsoft and Meta provide a unique, non-dilutive financing floor that effectively de-risks the infrastructure build-out compared to traditional data center REITs.
"Nebius has a credible path to a scalable AI infra platform, but the key risk is whether it can fund 20-25B of capex and avoid overwhelming dilution while preserving margins and customer concentration."
NBIS is pitched as a fast-growing AI infrastructure winner with Nvidia backing and marquee clients like Meta and Microsoft. The upside rests on expanding from renting compute to a full-stack AI platform and a capex buildout targeting 5GW by 2030, backed by $9.3B cash and 2026 revenue guidance of $3–3.4B with ~40% EBITDA margin. However, the story hinges on outsized capital expenditure and potential equity raises (ATM up to 25M shares), which risks dilution and funding frictions. Concentration risk (a few large customers), execution risk from post-acquisition integration, and competition from Nvidia and hyperscalers could compress margins or delay deployment. Real-world feasibility of 5GW and regulatory/energy costs are missing context.
The strongest counter is that Nebius may not be able to fund or monetize such rapid capex without heavy dilution, and a few key customers or slower AI demand could derail the thesis.
"Energy and regulatory costs for 5GW expansion plus acquisition integration risks threaten the 40% EBITDA margins despite contract financing."
The upfront payments provide a financing floor as Gemini notes, yet this ignores the energy and regulatory hurdles for scaling to 5GW by 2030. Those costs, unaddressed in the guidance, could compress the 40% EBITDA margins faster than hyperscaler pricing power erodes, especially with the ATM dilution already authorized. Combined with post-acquisition integration expenses, the math for sustainable cash flows weakens significantly even if utilization holds.
"Energy procurement strategy is the hidden variable that determines whether 40% EBITDA margins survive capex scaling—and it's completely absent from guidance."
Grok flags energy/regulatory costs compressing margins, but misses that Nebius hasn't disclosed capex per watt or power procurement strategy—critical unknowns. If they're locking in long-term renewable PPAs now, margins hold; if they're spot-buying power in 2026-2028, the 40% EBITDA target evaporates. The ATM dilution is a symptom, not the disease. The real question: does management have a power supply roadmap, or are they building data centers hoping energy costs stay favorable?
"Nebius is trapped in a commodity utility model where they lack the power-generation assets to protect their 40% EBITDA margin targets against hyperscaler innovation."
Claude, you’re hitting the right note on power, but the risk isn't just spot pricing—it's the 'utility trap.' By tying capex to 5GW, Nebius is essentially betting on infrastructure arbitrage. If hyperscalers like Microsoft and Meta develop proprietary silicon or more efficient internal cooling, they won't need Nebius's scale. The 40% EBITDA target assumes Nebius remains the primary landlord of choice, but that moat is paper-thin if they don't own the proprietary energy generation assets themselves.
"Nebius’s 40% EBITDA target hinges on a credible, scalable power procurement and financing plan; without it, the massive capex will dwarf cash flow, risking persistent negative FCF even with upfront hyperscaler payments."
Responding to Grok: energy/regulatory headwinds matter, but the bigger flaw is cash-flow timing and funding sustainability. $25B of capex with 40% EBITDA implies heavy debt service; with ATM dilution and potential delayed revenue recognition, Nebius could burn cash for years unless hyperscalers continue upfront payments or Nebius secures long-duration PPAs at scale. The article omits a credible power procurement and financing roadmap—without it, the 40% margin target looks optimistic.
Panelists generally express bearish sentiments regarding Nebius' long-term sustainability, citing massive capital expenditure requirements, potential dilution, and risks associated with energy costs and hyperscaler pricing power.
