Nebius Group N.V. (NASDAQ: NBIS) experienced a volatile week on Wall Street, with shares ultimately closing 5.7% higher despite a sharp 15.0% decline on Friday. The stock ended the trading session at $187.77, a drop of $33.20 that wiped out 96.8% of the $34.30 surge recorded on Tuesday. The dramatic reversal highlights the market's rapid reassessment of risks surrounding the company's AI infrastructure investments and client commitments.
NVIDIA Filing Sparks Initial Optimism, Then Fades
The week's action was largely triggered by a regulatory filing from NVIDIA Corporation (NASDAQ: NVDA), which disclosed a 9.3% beneficial ownership stake in Nebius. However, a closer examination revealed that 94.6% of that stake, or 21.07 million shares, consisted of warrants rather than common stock. These warrants were purchased on March 11 and cannot be exercised or sold before September 11, according to SEC rules requiring their inclusion when exercise is possible within 60 days. The filing did not indicate any new purchasing activity last week, leading traders to initially price in an endorsement premium that quickly dissipated.
Sector-Wide Sell-Off Amid AI Cost Concerns
The Friday sell-off was not isolated to Nebius. CoreWeave, Inc. (NASDAQ: CRWV) fell 11.4% to $71.88, while IREN Limited (NASDAQ: IREN) dropped 8.7% to $37.07. Despite the weekly gain, Nebius underperformed IREN, which rose 10.3% for the week. Trading volume for Nebius surged to 23.95 million shares, 34% above its 65-day average, reflecting heightened investor anxiety. The broader market sentiment was weighed down by Alphabet Inc. (NASDAQ: GOOGL) raising its capital expenditure plans, stoking fears about the escalating cost of AI development. By Wednesday, $8.55 billion had been withdrawn from U.S. growth funds.
Funding and Client Commitments in Focus
To ease funding pressure, Nebius secured a $775 million senior facility on July 17, backed by deployed GPUs and customer cash flows. The loan matures on October 31, 2030, with pricing at SOFR plus 2.5 percentage points. Chief Operating Officer Ophir Nave called it an important step, noting it covers over 100% of related capital expenditure. The company also reported securing more than $40 billion in additional contracted revenue, naming Microsoft Corporation (NASDAQ: MSFT) and Meta Platforms, Inc. (NASDAQ: META) as clients. Nebius confirmed that its newest tranche of Microsoft capacity has been fulfilled.
Financial Results and Outlook
First-quarter revenue surged 684% to $399 million, with adjusted EBITDA reaching $129.5 million. However, capital spending on property, equipment, and intangibles totaled $2.47 billion. In May, Nebius raised its 2026 capital expenditure forecast to between $20 billion and $25 billion, up from a prior range of $16 billion to $20 billion. This aggressive spending underscores the capital-intensive nature of the AI infrastructure business, making client budgets a critical factor in the company's valuation.
Upcoming Catalysts and Risks
Meta and Microsoft are set to report earnings after Wednesday's close, while the Federal Reserve will conclude its July 28-29 meeting. As of Friday, futures implied a 38% probability of a 25-basis-point rate hike. Risks remain elevated for Nebius, including the need to deploy capacity on schedule, retain key clients, and manage increased debt expenses. Any delays, higher financing costs, or a slowdown in AI demand could pressure returns. Friday's swift reversal underscores how quickly market sentiment can shift from optimism to caution.
