Nebius Stock: A 454% Revenue Jump, a $20–25 Billion Buildout, and the Long Wait for Positive Cash Flow

Two numbers frame the debate around Nebius right now, and they pull in opposite directions. The first is 454% — the year-over-year revenue growth the company reported for its latest quarter. The second is 2034 — the year Rosenblatt expects the AI infrastructure builder to finally generate positive free cash flow. Everything in between is a question about financing.

The stock's recent slide is best understood as a repricing of time rather than a verdict on the business. A daily move of -3.8% extended a retreat that followed a sharper -9.8% selloff the prior session, after a hotter-than-expected U.S. inflation reading and mounting rate-hike expectations weighed on AI infrastructure names. Reuters reported further premarket losses as those rate and funding-cost concerns intensified. The market is no longer asking only how large demand might become. It is asking what return the capital required to serve that demand will produce.

The Buildout Sets the Bar

Nebius has penciled in capital expenditures of $20–25 billion for 2026. That figure belongs at the center of any valuation. Judging the company purely on its top-line trajectory leaves out the financial precondition for that growth.

None of this means expansion should be read as a weakness. New capacity can lay the groundwork for later returns. But a convincing demand forecast and an economically viable buildout are two different things, and the gap between them tends to widen when rates rise.

Rosenblatt puts free cash flow at -$3.41 billion for the reported second quarter and sees positive free cash flow arriving only in 2034. That is an analyst projection, not a fixed schedule — yet it marks the key caveat sitting behind the firm's otherwise optimistic view. For investors, the long wait matters more than any single weak trading day, because it means operational progress and financing must be assessed side by side over an extended horizon.

The Demand Case Is the Strongest Counterargument

The bullish side is not easily dismissed. Rosenblatt points to quarterly revenue of $582.3 million, growth of 454% from a year earlier, and adjusted EBITDA of $236.2 million — a substantial counterweight to the funding worries.

Those figures argue against the idea that Nebius is merely an abstract bet on demand that may or may not materialize. The business is already expanding at a rapid clip. Still, valuation requires separating operating profit from free cash flow: the buildout consumes capital that an earnings metric does not fully capture.

Microsoft and Meta together account for more than half of a reported order backlog exceeding $40 billion, according to Rosenblatt, which initiated coverage on October 7 with a Buy rating and a $304 price target. Large customers give the growth story concrete anchors. A backlog, though, is not the same as cash in hand — it describes business potential, while funding the buildout is a present-tense concern. The two belong together but should not be conflated.

Funding Remains the Proving Ground

Nebius has issued $5.75 billion in convertible bonds and raised more than $2 billion through a share placement in 2026. Those steps show the expansion is already drawing on multiple funding channels.

Anxiety over CoreWeave's bonds explains part of the sector's jitteriness — Reuters reported a bond yield above 15% there and record-high costs for default protection. That is not evidence of identical risks at Nebius, and lumping the two companies together would be as misguided as exempting Nebius from the funding debate simply because of its growth rate.

The earnings picture offers its own nuance. The August 13 report showed revenue of $582.30 million, up 454% year over year, with earnings per share of -$0.12. Analysts had expected -$0.67, so the reported figure came in better than forecast — a positive operational signal, though not an answer to whether further expansion is sustainable. A reported loss per share cannot be equated with proof of durable profitability.

Reading the Signals Without Overreading Them

Gartner expects more than 80% of neocloud providers to lose their independence by 2030. The warning deserves attention, but it is neither a specific insolvency forecast for Nebius nor evidence that every provider will fail economically. Deriving a verdict on Nebius directly from an industry projection skips the decisive analytical step: company-specific results and financing conditions. Correlated share prices are no substitute for that work.

The same caution applies to insider activity. CRO Marc Boroditsky sold shares on Monday under a pre-arranged Rule 10b5-1 plan — a constraint that must be part of any assessment. Reading the sale as a spontaneous reaction to recent market turbulence would not be justified.

Analyst targets capture the disagreement. BNP Paribas Exane sits at $399, Rothschild & Co Redburn at $84, with the consensus at $245.69. That spread is no reason to simply follow the most bullish house; it mainly shows how far estimates diverge. A price target is an expectation, not a guaranteed company value.

Two judgments can hold at once: Nebius has delivered substantial growth, and the recent decline does not automatically make the stock cheap. The more defensible stance is neither blanket sector pessimism nor blind faith in AI demand. The company should be measured by how reliably growth converts into economic value — and that is where the debate belongs, not in the hunt for a bargain after a steep drop. Until progress shows up in the relationship between buildout, financing, and free cash flow, the growth story remains powerful while its financial test stays open.
