Nebius Group (NBIS) stock has emerged as a standout AI infrastructure play throughout 2026. Currently hovering around $231 per share as of Monday’s session, the neocloud provider captured renewed investor interest following disclosure of a significant stake by a prominent hedge fund manager.
Leopold Aschenbrenner — previously a researcher at OpenAI and now founder of Situational Awareness, which oversees approximately $13.7 billion in assets — submitted a 13G filing to the SEC revealing an acquisition of 12.4 million shares of NBIS stock. This transaction establishes the fund’s stake at 5.6% of total outstanding shares.
The investment aligns with a consistent strategy throughout Aschenbrenner’s portfolio. Situational Awareness maintains existing holdings in Iren (IREN) and CoreWeave (CRWV), both neocloud operators that provide GPU infrastructure for AI applications. Adding Nebius completes what appears to be a strategic trio of concentrated AI infrastructure positions.
Neocloud providers differentiate themselves from conventional hyperscale platforms such as AWS, Azure, or Google Cloud by concentrating exclusively on GPU-heavy computing resources. Unlike traditional cloud services that package storage, databases, and analytics tools, neoclouds deliver pure GPU computing power designed specifically for AI model training and inference. The value proposition is clear: hyperscalers haven’t expanded GPU capacity rapidly enough, creating opportunities for neoclouds to bridge the supply shortfall.
Impressive Financial Performance Fuels Optimism
Nebius’s recent quarterly results provided substantial evidence supporting bullish sentiment. The company announced Q1 revenue of $399 million, exceeding analyst projections of $375 million. This figure represents a remarkable 684% increase versus the prior year’s comparable period. Earnings per share registered at -$0.23, significantly outperforming the consensus estimate of -$0.77.
Executive leadership has established an ambitious revenue objective: achieving $7 billion to $9 billion in annualized revenue run rate before 2026 concludes. With a present market capitalization of $58 billion, this translates to a forward price-to-sales multiple of approximately 6.4x using the upper range — elevated pricing, yet defensible for an enterprise experiencing this growth velocity and securing multi-year agreements with leading AI companies.
Nebius has also increased its 2026 capital expenditure forecast to $20 billion–$25 billion, reflecting completely allocated AI infrastructure capacity and confirmed demand commitments extending through 2027.
