Nebius's Record Quarter Masks a Build-Out Bottleneck That Even Nvidia's Backing Can't Resolve

Nebius beats Q2 with 454% revenue growth and $40B backlog, but Vineland delays and $20-25B capex plan trigger share pullback.

The market's reaction to Nebius's second-quarter numbers told two stories at once. First came the euphoria — a 34 percent single-day surge as investors digested revenue that had more than quintupled. Then came the reckoning, with shares slipping 3.8 percent to €215.95 the following session as traders weighed whether the company can physically build fast enough to satisfy the demand it has already booked.

The numbers themselves were hard to argue with. Revenue hit $582.3 million, up 454 percent year over year, with the AI Cloud segment alone growing 514 percent to $574.9 million — now representing 98 percent of total turnover. The per-share loss of $0.12 landed far ahead of the $0.82 analysts had braced for. Management also raised its contracted power capacity target to 5 gigawatts by year-end, up from a prior 4 gigawatts, while the annualized contract revenue base climbed to $3 billion.

The Construction Question

The immediate catalyst for the post-earnings pullback traces back to a caution flag raised before the report even landed. DA Davidson trimmed its price target from $250 to $175 on Monday, holding a Neutral rating, with the rationale pinned squarely on delays at the company's Vineland data center campus — a facility that may no longer come online this year as originally planned.

That warning sits awkwardly against the record bookings. Nebius's order backlog now exceeds $40 billion, including four contracts worth more than $1 billion apiece with partners such as Cohere and Reflection AI. The Reflection AI deal, signed in early August, secures compute capacity through 2029 and includes access to Nvidia's GB300 chips. Nvidia itself holds 9.3 percent of Class A shares, some via a pre-funded warrant that becomes exercisable no earlier than September 11 — a strategic entanglement that many read as a credit signal for future orders.

But the gap between contracted demand and operational capacity is the crux. Adjusted EBITDA in the AI segment reached a 50 percent margin, and long-term contracts are pricing at $20–25 million per megawatt, with spot prices fetching $40–50 million. Management estimates investments pay back in roughly 22 months. Customer prepayments are expected to exceed $9 billion in 2026, covering 50–60 percent of planned capital expenditures.

The Capital Calculus

That capex figure is where the bear case sharpens. Nebius plans to invest between $20 billion and $25 billion in 2026 — nearly ten times the current quarterly revenue run rate. From 2027 onward, the company intends to add over a gigawatt of capacity annually. Sustaining that pace demands uninterrupted access to fresh funding, whether through customer prepayments, debt, or equity.

The equity route carries its own cost. Through June, Nebius sold 12.7 million Class A shares at a weighted average price of $223.60, raising roughly $2.8 billion in gross proceeds. Another 12.3 million shares remain available for sale — a persistent overhang that could pressure the stock with each new tranche. Insider activity adds to the optics: CEO Arkady Volozh and the chief infrastructure officer both trimmed positions in July, though some transactions were tax-motivated.

The GAAP picture complicates the narrative further. Despite the adjusted profitability, Nebius posted a net loss of $190.4 million for the quarter. The gap between adjusted and official figures remains substantial, and short interest exceeds 20 percent of shares outstanding. Investor Michael Burry has reportedly built short positions around the €212 level, signaling meaningful skepticism about valuation.

What Happens Next

The technical setup suggests a market catching its breath. The stock trades about 16 percent above its 50-day average of €193.30, and roughly 71 percent above the 200-day line at €126.31 — though the secondary article cites that longer-term benchmark slightly lower at €125.71. Either way, the stock sits about 14 percent below its 52-week high of €261, with resistance clearly forming in the upper range.

The immediate test comes on August 25, when shareholders gather in Amsterdam for the annual meeting. Management is expected to provide further detail on capacity planning and potentially the Vineland construction timeline. Beyond that, Nebius must expand its asset-backed financing beyond the existing $775 million to shoulder the 2026 investment burden. Success on that front, combined with an annualized revenue run rate of $7–9 billion by year-end, would likely force a re-rating of the current €42.49 billion market capitalization.

A slip in either direction — further Vineland delays or a tightening of the hardware supply chain, particularly around Nvidia components — would refocus the debate on capital burn. The 200-day average serves as the fundamental warning line; a sustained break below it would signal that the growth story itself is being questioned. Until then, Nebius remains a high-risk growth bet whose valuation hinges on converting announcements into physically operational data centers — and doing so before the financing clock runs out.
