Key Highlights

● Nebius closed steeply lower on Friday, October 30, 2026.

Nebius Group (NASDAQ:NBIS) fell sharply on Friday, October 30, 2026, closing steeply lower, according to market data. The AI cloud company was one of many stocks tied to the Data Center buildout that sold off as investors grew wary of how much the AI boom costs and how it is being financed.

No same-day company catalyst was given for the decline. Nebius moved with the AI-infrastructure group in a session when the Nasdaq Composite fell 747.73 points to 25,437.00, its worst day since June 5.

Recent company developments

A separate market brief noted two recent items for Nebius: a $3.5 billion bridge Loan and a plan for 1 gigawatt of capacity in 2027. The brief did not tie either item to Friday's share move.

Nebius provides Cloud Computing infrastructure built on graphics processors for companies that develop and run AI models. Its expansion requires heavy Investment in data centers and hardware, which ties the stock closely to investor sentiment about AI spending and access to financing.

A broad retreat from AI hardware

The selloff began with Intel (NASDAQ:INTC), whose weak fourth-quarter outlook and warning of cash burn sent its shares to a record one-day decline and dragged the Philadelphia Semiconductor index down to 10,688.80. Nvidia (NASDAQ:NVDA), the leading supplier of AI chips, lost about $185 billion in market value, according to market data.

Amazon (NASDAQ:AMZN)'s third-quarter report added to the anxiety. Its trailing 12-month free Cash Flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier, as spending on AI infrastructure ballooned, and the company said 2027 Capital spending would be "meaningfully more" than this year's. Alphabet (NASDAQ:GOOGL) was still under pressure after its worst day ever on Thursday, when it reported negative free cash flow of $9.1 billion.

"Together, Amazon, Google, Microsoft (NASDAQ:MSFT) and Meta (NASDAQ:META) spent more than $200bn in the third quarter alone," said a market analyst, who warned that "the risk is that higher financing costs will absorb more of the cash generated".

Other AI-infrastructure names

Nebius had plenty of company among decliners. CoreWeave (NASDAQ:CRWV), another provider of AI computing capacity, closed sharply lower with no company-specific news. Oracle (NYSE:ORCL) fell with the AI-infrastructure sector after an early rise, and Bloom Energy, which supplies power for data centers, fell before the opening bell. Software and cloud names including Datadog (NASDAQ:DDOG), Snowflake (NYSE:SNOW), MongoDB (NASDAQ:MDB) and DigitalOcean (NYSE:DOCN) also slid.

"The message from investors is becoming clearer: strong AI Demand is no longer enough on its own," said a senior market analyst.

The broader market was hit hard. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average lost 572.25 points to 51,770.31, and the Russell 2000 slid 47.37 points to 2,811.84. Technology was the worst of the 11 S&P 500 sectors, while energy, consumer staples, health care and utilities rose. The Federal Reserve held rates steady this week, but three Fed officials said on Friday that rates need to be higher, and futures markets are pricing a likely December hike.

What to watch

Investors will look for further detail on Nebius's capacity plans for 2027 and how the company funds its expansion. Broader sentiment toward AI infrastructure will also be key, with Palantir (NASDAQ:PLTR) reporting on Monday, November 2, Super Micro Computer (NASDAQ:SMCI) on November 3 and Qualcomm (NASDAQ:QCOM) on November 4.

The midterm elections on Tuesday, November 3, are also in focus. Investors are watching state and local races, including in Texas, for implications for data-center development. The October jobs report, due Friday, November 6, will shape expectations for the Fed's next move.
