So here's a fun puzzle in the AI infrastructure world. You have two companies, CoreWeave Inc. (CRWV) and Nebius Group N.V. (NBIS), that went public around the same time. Both are in the business of providing the heavy-duty computing power that fuels artificial intelligence. But over the past year, their stock performances have started to tell very different stories. CoreWeave is up a respectable 22% year-to-date, but Nebius has surged more than 37%. What gives?
It turns out investors are starting to look past the sheer growth potential of AI and are instead focusing on the old-fashioned stuff: balance sheets, capital intensity, and how much money these companies are burning to build their empires.
The Balance Sheet Burden
Paul Meeks, head of technology research at Freedom Capital Markets, put it bluntly in a recent interview. He said CoreWeave's underperformance isn't because it has a riskier business model. It's because it's carrying a "heavier balance-sheet burden." In simpler terms, CoreWeave has been much more aggressive—and expensive—in building out its AI infrastructure. Nebius, by contrast, has taken a more measured approach and maintains a cleaner financial position.
Felix Wang, tech sector head at Hedgeye Risk Management, added another layer, noting that CoreWeave's story depends heavily on a small number of big contracts with hyperscalers to keep investors interested. That's a lot of eggs in a very few, very large baskets.
When Financing Fears Spread
This focus on financial health was thrown into sharp relief recently when concerns about financing at CoreWeave triggered a sector-wide sell-off. Rivals like Nebius and Applied Digital Corp (APLD) got caught in the downdraft too. It was a stark reminder to the market: building AI data centers is incredibly capital-intensive, and these companies are leaning heavily on debt and private credit to fund their ambitions.
Analysts at Truist, led by Arvind Ramnani, echoed this, telling reports that companies in this space will likely need a steady diet of new financing to keep expanding. It's a high-stakes game of spending money to make money, and investors are getting nervous about the tab.
