Nebius Rides Nvidia’s Coattails — But the Debt Question Hangs Over the AI Cloud Race

The arithmetic of the AI infrastructure boom keeps getting bigger. Nvidia’s equity stakes in artificial-intelligence cloud providers ballooned to $99 billion by July 26, up from just $7 billion a year earlier, with more than $40 billion of fresh commitments made in 2026 alone. Nestled within that portfolio is Nebius, the Amsterdam-based cloud operator that pocketed a $2 billion investment from the chipmaker back in March — a relationship that now sits at the heart of a much larger strategic question.

Nebius shareholders have plenty to cheer about in the near term. The company’s second-quarter results delivered the message investors wanted to hear: demand remains robust, pricing power is improving, and four contracts each worth north of $1 billion are locking in what analyst Sacha Kavanagh describes as healthy returns. The market responded in kind, with shares climbing 6.2 percent to €192.06 in a single session — though the stock has since settled around €185.10, still hovering just above its 50-day moving average of €184.58.

A widening web of capital

The Nvidia connection runs deeper than a single equity check. The chip giant has committed roughly $30 billion to OpenAI, $2 billion to CoreWeave, and now holds an Intel stake valued at $30 billion. Nvidia CFO Kress pegs total investments in AI labs at nearly $50 billion, while CNBC reports the company is mobilizing more than $500 billion through partnerships to drive sales of its own GPUs. Nebius occupies a fixed slot in that ecosystem as a cloud-infrastructure partner.

That ecosystem is also getting crowded. Crusoe, a direct competitor, just raised $3 billion in fresh capital at a $30 billion valuation — a threefold jump in ten months — in a round led by Atreides Management and Valor Equity Partners, with Mubadala Capital joining in. The funding followed a $13 billion cloud agreement with Jane Street, and Crusoe is now in talks with banks about an initial public offering.

For Nebius investors, the Crusoe surge cuts both ways. It validates the sheer scale of demand for AI compute capacity, but it also demonstrates how quickly capital is flooding into rival infrastructure players. The valuation leap suggests investors will pay premium prices for AI-focused cloud capacity — a dynamic that supports Nebius’s own multiple even as it raises the competitive stakes.

The leverage question

The more pressing concern is how the industry pays for its ambitions. Jefferies analyst Christopher Wood warns of a bond wave: technology companies issued $223 billion in debt between January and August 2026 to fund AI infrastructure — more than double the total for all of 2025. CoreWeave alone has taken on $8.5 billion in March and another $2.6 billion in August, according to its own disclosures.

Should investors sell immediately? Or is it worth buying Nebius?

Nebius has so far charted a different course. Rather than leaning on the bond market, the company relies on customer prepayments covering 50 to 60 percent of capital costs. The anchor deal is a $12 billion agreement with Meta, expandable to $15 billion over five years, supplemented by Nvidia’s $2 billion investment. The model has kept Nebius’s balance sheet comparatively lean — its price-to-earnings ratio of 5.15 sits above the industry average of 3.7, a premium the market has underwritten with a 120.2 percent share-price gain over six months.

The central test is whether that capital-efficient structure can hold as Nebius pushes toward more than five gigawatts of capacity by 2030, with annual build-outs exceeding one gigawatt. The company is also reportedly in talks to acquire AI21 Labs, after Nvidia walked away from negotiations with the Israeli firm, according to The Information. No purchase price or terms have been confirmed.

Reading the tape

The stock’s trajectory tells a story of consolidation after a furious run. Shares are up 152 percent year to date and 231 percent over twelve months, yet they remain roughly 26 to 29 percent below the 52-week high of €261.00. The annualized volatility of 159 percent suggests the market is already pricing in considerable uncertainty about valuation and financing structure.

The market capitalization stands at approximately €47.76 billion. The four large contracts, generating returns of $20 million to $25 million per megawatt, provide a tangible earnings foundation. The bull case rests on Nebius maintaining its prepayment-driven expansion model while competitors pile into debt — a differentiation that would matter enormously if financing costs rise or AI demand softens.

The bear case is equally straightforward. Customer prepayments are tied to customers’ own growth expectations. If the AI capex cycle falters, or if rising bond yields make debt financing more expensive across the industry, the willingness of clients to front 60 percent of capital costs could evaporate. An AI21 acquisition struck at unfavorable terms could also tie up capital without delivering the hoped-for synergies.

The near-term catalysts are clear: confirmation or collapse of the AI21 discussions, followed by evidence on whether the expansion plan toward the 2027 target of five gigawatts stays on schedule. Between Nvidia’s deepening financial web, Crusoe’s valuation sprint, and the industry’s growing reliance on borrowed money, Nebius is navigating a moment where operational strength and systemic risk are converging — and the market is watching both sides of that equation.
