From Russian search giant to GPU cloud powerhouse — Nebius Group’s transformation is unlike anything in tech right now. Here’s what investors need to know before the May 13 earnings.
There’s a strange footnote in the Nebius Group story that most people skip over. This is the same company that used to be called Yandex — Russia’s answer to Google. In August 2024, it changed its name to Nebius Group and reinvented itself as an AI cloud infrastructure company serving the global market from the Netherlands.
That backstory matters because it explains something unusual: Nebius came into existence as a fully funded, operationally mature business with real engineering talent, not a startup pitching slides. And in less than two years since rebranding, the stock has gone from a 52-week low of $23.25 to a high of $168.71.
As of May 2, 2026, NBIS trades at $154.49. It’s up 71.8% year-to-date and has outperformed the S&P 500 by 66.3 percentage points in 2026 alone.
The question isn’t whether this has been a great trade. It obviously has. The question is what happens next.
Why Nebius Group NBIS Stock Has Exploded in 2026
The revenue numbers tell most of the story. Nebius reported $529.8 million in trailing twelve-month revenue, up 500.8% year-over-year. The most recent quarter showed $150 million in revenue, a 44.5% sequential jump. These are not the kind of numbers you see from mature businesses.
Nebius builds what it calls full-stack AI infrastructure: large-scale GPU clusters, cloud platforms, and developer tooling for AI workloads. Think of it as a purpose-built alternative to AWS or Google Cloud, specifically optimized for the inference and training demands of AI companies that don’t want to be at the mercy of hyperscaler pricing.
The gross margin of 68.63% reflects how defensible that position is when you land a customer. That’s legitimately strong for a cloud infrastructure business.
On May 1, Nebius announced it was acquiring Eigen AI for $643 million. Eigen’s technology allows AI models to run more inference per GPU without adding physical capacity — in plain terms, it squeezes more output from existing hardware. The market liked this immediately: NBIS jumped 11.76% on the news, closing at $154.49 from the prior session.
NBIS Earnings Preview: What to Watch on May 13, 2026
The next earnings report lands on May 13. Here’s what matters.
Revenue Growth Trajectory
The YoY growth rate of 500.8% will inevitably slow as the base gets larger. The real question is how Q1 2026 revenue compares sequentially. If Nebius delivers another 30-45%+ quarter-over-quarter gain, the bull case stays intact. If growth decelerates sharply, that’s when the elevated valuation becomes a problem.
Gross Margin Stability
The last reported quarter showed a gross margin of 70.6%. For NBIS to justify its current price-to-sales ratio of 73.78x, margins need to stay in that range or improve. Any compression below 65% would be a yellow flag.
Path to EBITDA Breakeven
Current EBITDA sits at -$192.2 million. The operating margin is -102.99%. These numbers are uncomfortable, and management will need to show a credible roadmap toward profitability — not necessarily profit itself, but a narrowing loss. Investors in high-growth AI infrastructure stocks are generally tolerant of losses, but they need to believe the losses are finite.
Commentary on Eigen AI Integration
The $643 million acquisition closed right before earnings. How management frames the integration timeline, expected synergies, and what it does to capex guidance will move the stock.

Nebius Group Valuation: Expensive or Just Misunderstood?
The trailing P/E ratio is 1,404x. The forward P/E is -152x (negative because analysts expect ongoing losses). Price-to-sales is 73.78x. By any traditional metric, this stock looks expensive.
But here’s the thing about traditional metrics: they’re designed for businesses with stable cash flows and predictable margins. Nebius is neither of those things right now, and deliberately so. The company is in the land-grab phase of AI infrastructure buildout, spending aggressively to acquire GPU capacity and customers before the market consolidates.
The more useful lens is the PEG ratio, which sits at 0.63x. A PEG below 1.0 suggests the growth rate more than justifies the P/E multiple. Given revenue growing at 500%, even a very high absolute P/E starts to look reasonable in relative terms.
The DCF model run on current projections — using a FCF margin expansion path from roughly 2% (Year 1) to 18% (Year 10) — puts the base-case intrinsic value significantly above the current price. The enterprise value of $35.12 billion against a projected revenue trajectory makes the stock look attractively valued on a 10-year horizon, with the model implying an annual return well above the 11.5% cost of capital.
None of that means the stock can’t fall 30% in the next six months. It absolutely can. The 30-day historical volatility of 78% means two-standard-deviation moves are a normal week for NBIS.
Nebius Group AI Infrastructure: The Competitive Moat Question
The bear case on Nebius ultimately comes down to one question: can a $34 billion company compete with AWS ($2.88 trillion Amazon), Azure ($3.08 trillion Microsoft), and Google Cloud ($2.25 trillion Alphabet)?
The short answer is: probably not head-to-head. But that might not be the right question.
Nebius is targeting AI-native companies that need high-density GPU compute without the overhead of general-purpose cloud platforms. It’s a focused market — inference workloads, AI training, model serving — where the hyperscalers are actually less optimized than they appear. AWS wasn’t built for GPU-heavy AI workloads. It was built for web applications and enterprise software.
The NVIDIA strategic alliance matters here. Access to cutting-edge GPU allocation is a real competitive advantage when H100s and B200s are chronically oversupplied with demand. Nebius’s ability to source, deploy, and manage high-density GPU clusters at scale is not something a startup replicates in a year.
The Eigen AI acquisition adds a layer of software differentiation. If Nebius can deliver 20-30% better inference efficiency on the same hardware, that’s a real cost advantage it can pass through to customers or pocket as margin improvement.
NBIS Stock: The Institutional Picture and Short Interest
Institutional ownership stands at 48.67% of shares. That’s meaningful — it means professional money managers have done their diligence and decided the risk is worth taking. The current ratio of 3.08x and quick ratio of 2.96x confirm the company has the liquidity to survive a rough quarter or two.
But 19.89% of the float is sold short. That’s a large bet against the stock. About 44 million shares are short as of April 15, with the prior month showing 43 million — the short interest is growing, not collapsing.
Insider transactions over the past three months show 9 sells and 0 buys. The largest single sale was 31,357 shares by Andrey Korolenko on April 6 at $111.20 per share. Multiple executives have been trimming. This doesn’t mean the company is doomed — insiders sell for lots of reasons — but it does mean insiders aren’t using their own money to signal confidence at current prices.
Should You Buy, Hold, or Sell NBIS Stock Now?
Fourteen Wall Street analysts say Buy, with a mean target of $170.29 and a high target of $291. The median target of $172 is very close to the mean, which suggests there’s reasonable consensus around that range rather than a few outliers pulling the average up.
At $154.49, NBIS sits 7.6% below resistance at $165.03, which has been tested six times recently without breaking. Above its 50-day SMA ($121.65) and 200-day SMA ($98.84) comfortably. Technically the uptrend is intact, but momentum, as measured by the MACD histogram, has turned negative — the stock needs the May 13 earnings to act as a fresh catalyst.
If you’re already long: the long-term trend supports holding. A stop below the 50-day SMA ($121.65) gives you a defined exit if the thesis breaks.
If you’re looking to buy: the setup is slightly stretched right now. A confirmed move above $165 with strong volume would be the cleaner entry. Alternatively, a pullback toward $140-145 on no bad news would improve the risk/reward significantly.
If you’re short: the combination of a buy-rated analyst consensus and an upcoming earnings catalyst makes this a dangerous place to press a short position. Short squeezes in high-short-interest stocks can be violent — 19.89% float short with a 2.2x days-to-cover ratio means covering could happen quickly.
The May 13 earnings report is the pivot point. Between now and then, NBIS stock is essentially a coin flip with a slight upward lean from the Eigen acquisition tailwind.
