Nebius Falls 5% as Investors Question AI Cloud Returns

Nebius stock fell alongside other AI cloud providers on Thursday as investors questioned whether the sector can earn adequate returns from its costly infrastructure. The decline followed a sharp sell-off in CoreWeave shares and fresh concerns about how long AI investment may take to pay off.
Nebius was down about 5% in late-morning trading, CNBC reported, while CoreWeave shares continued to slide after losing 15% on Wednesday. The pressure spread beyond companies with heavy debt, raising questions about the business model shared by specialized cloud providers serving AI companies.
Investors scrutinize the neocloud model
Neocloud providers supply computing capacity built for artificial intelligence and machine learning. CoreWeave buys GPUs from Nvidia and rents computing power to other companies, including hyperscalers such as Meta. Nebius sells similar services to similar customers, according to Gil Luria, head of tech research at DA Davidson.
“Look at a comparable company like Nebius,” Luria said. “They literally sell the same thing to the same companies and have almost no financial leverage.”
That comparison suggests the latest pressure is not limited to companies carrying large debt burdens. CNBC reported that Nebius and IREN fell together on Thursday, while AI colocation firms also declined. Investors may be reassessing returns across providers of AI infrastructure, not just the finances of one company.
The consequences reach beyond stock prices. If investors become less willing to fund new computing capacity, AI infrastructure providers could face a tougher path to financing expansion, while customers relying on rented computing power may encounter changes in how providers build and price capacity. The sources describe investor concerns but do not report any change to Nebius services or customer contracts.
There is a longer-term concern. Gartner forecast that “cost pressure and a lack of a differentiating business model will force over 80% of neocloud providers to cease independent operations” by 2030, according to its report cited by CNBC. Investors are also weighing whether demand will generate returns quickly enough to justify the capital required.
CoreWeave’s debt adds pressure
CoreWeave has become a focal point because of its borrowing and role in the sector. CNBC reported that the yield on its 2032 bond rose to 15.77% on Thursday, while its five-year credit default swap spread reached 1140 basis points, or 11.4% per year. FactSet data cited by CNBC put CoreWeave’s forward debt-to-equity ratio at 667-to-1.
The sell-off followed concerns about an AI slowdown, tighter credit conditions and rising inflation, as well as social media posts. CNBC said several technology investors it spoke with could not identify a single specific cause for the slump in neocloud stocks.
CoreWeave’s exposure also ties the episode to Nvidia. Yahoo Finance reported that Nvidia invested $2 billion in CoreWeave stock in January and now holds 47.2 million shares, or around 10% of the company. CoreWeave has committed to using Nvidia technology to build more than 5 gigawatts of AI factories by 2030.
Nvidia CEO Jensen Huang may face pressure to address confidence in CoreWeave, Yahoo Finance reported, given Nvidia’s investment and the companies’ commercial ties. Bernstein analyst Madison Rezaei, meanwhile, said in a Thursday note: “In our view, the company's long-term business model remains economically challenged; we maintain our Underperform.”
The sell-off leaves investors watching whether pressure on CoreWeave’s debt and shares continues to spread across AI infrastructure providers, including Nebius.
