Wall Street's New Math: Nebius's Prepaid Contracts Rewrite the AI Infrastructure Playbook
Published on 08/17/2026 at 15:51 | Redaktion boerse-global.de
The most telling number in Nebius's latest earnings release isn't the revenue growth, the backlog, or even the raised capacity target. It's the fact that roughly 70 percent of new contracts signed in the second quarter came with customer prepayments covering half to two-thirds of the associated capital expenditure.
That single data point explains why analysts are scrambling to reset their price targets with unusual urgency — and why the stock has become one of the most hotly debated names in the AI infrastructure trade.
Nebius shares closed Friday at 239.70 euros, up 8.4 percent on the day, after the company's Saturday earnings release triggered a re-rating that has now lifted the stock roughly 50 percent in a single week. The equity still sits about 8.2 percent below its 52-week high, but the velocity of the move has caught even seasoned traders off guard. On a 30-day basis, annualized volatility runs at 178 percent, and the shares now trade 23 percent above their 50-day moving average of 194.10 euros — a stark illustration of how quickly the market has repriced the story.
The Prepayment Signal
The mechanics of Nebius's business model are shifting in ways that matter more than the headline numbers. Customers are no longer simply renting cloud capacity as needed; they are effectively co-investing in infrastructure that doesn't exist yet. Prepayments of that magnitude signal that clients are betting on the continued scarcity of power and data-center floor space — not just on Nebius's ability to deliver chips and software.
The company's second-quarter results bear this out. Revenue surged 454 percent year over year to $582.3 million, with the AI Cloud segment alone growing 514 percent. Adjusted EBITDA margin came in at 41 percent, slightly ahead of the roughly 40 percent margin baked into the full-year guidance of $3.0 billion to $3.4 billion in revenue.
Management also confirmed plans for capital expenditures of $20 billion to $25 billion in 2026, backed by a liquidity reserve of $8 billion. Customer prepayments for the year are now expected to exceed $9 billion — a figure that helps explain why investors remain relatively calm about the scale of planned spending.

A Target That Keeps Moving
The analyst community is struggling to keep pace. Northland Securities' Nehal Chokshi lifted his price target on Thursday from $248 to $410 — more than 1.5 times the previous level — while reiterating a buy rating. It now ranks among the most aggressive calls on the Street. Citigroup followed suit on Friday, raising its target from $278 to $324 and holding its buy recommendation.
Bank of America had already adjusted its target twice in quick succession, a pattern that reflects how rapidly the underlying data is evolving. Each new print seems to render the previous estimate obsolete before it has had time to settle.
Not everyone is on board. D.A. Davidson cut its rating to Neutral and slashed its price target shortly before the earnings release — a call that now looks like it was made from a different vantage point, before the scale of the quarter became clear.
The Capacity Race
The company has raised its target for contracted power capacity to 5 gigawatts by year-end, up from the previous goal of over 4 gigawatts. That revision speaks to a broader industry dynamic: the bottleneck in AI is no longer computing chips but electricity and physical infrastructure. Competitors like CoreWeave are riding the same wave, as Reuters noted in its coverage of the sector's momentum.
Nebius's total customer commitments now exceed $40 billion, with four individual contracts averaging over $1 billion each. The total contract value booked in the second quarter nearly quadrupled sequentially, and for new customers it grew more than ninefold.
The relative strength index sits at 64.2, suggesting the stock hasn't yet reached overbought territory despite the recent surge. But with the shares trading at levels that already embed substantial future growth, the question for investors is whether the prepaid-capacity model can convert these commitments into durable, long-term revenue — or whether the current price targets are simply front-running a story that still has much to prove.
