NVIDIA's 9.3% Stake Disclosure Sends Nebius Soaring Over 18%

Nebius Group (NBIS-US), an AI cloud infrastructure provider, surged over 18% on Tuesday (21st) to close at $216.92 per share. This followed NVIDIA's latest regulatory filing revealing its beneficial ownership in Nebius reached 9.3% when including shares obtainable through warrants. The market interpreted this as a vote of confidence from the AI chip leader, driving capital back into AI infrastructure stocks.

NVIDIA's regulatory filing submitted on Monday showed the company currently holds a 9.3% stake in Nebius. Following the disclosure, Nebius shares soared on Tuesday, reaching an intraday high of $217.62, and closing up over 18% at $216.92 per share.

Headquartered in Amsterdam, Nebius primarily provides AI computing and cloud infrastructure services. The company's stock had previously declined from last month's peak due to a broad correction in AI-related stocks. However, with the revelation of NVIDIA's stake size, market confidence in its growth potential and strategic value has been rekindled.

NVIDIA first disclosed a minor stake in Nebius in early 2025 and announced a $2 billion investment in the company this March. NVIDIA CEO Jensen Huang stated at the time that the two companies were deepening collaboration and expanding cloud service capacity to meet the rapidly growing global demand for AI computing.

NVIDIA itself rose 1.75% on Tuesday. Another AI cloud service provider backed by NVIDIA and competing with Nebius, CoreWeave (CRWV-US), also gained 7.62%, indicating a broader return of capital to the AI infrastructure sector.

Wall Street analysts have also maintained a positive outlook on Nebius. A Citigroup analyst, after attending the company's 'Inflection' event in San Francisco last month, noted that as AI applications expand, Nebius's pricing power could prove more sustainable, and its expanding software product portfolio demonstrates greater strategic value.

Citigroup currently maintains a 'Buy' rating on Nebius with a $287 per share price target, above the Visible Alpha consensus target of approximately $276.

Factoring in Tuesday's gains, Nebius has risen approximately 141% year-to-date and achieved a 314% increase over the past 12 months.
