Nebius Group shares jumped to a record high on Monday after Nvidia chief executive Jensen Huang praised the company as one of a small group of world-class AI clouds at COMPUTEX in Taiwan. He said Nebius was growing incredibly fast and pointed to customers including Cursor, World Labs, Revolut and Shopify.
The move gave fresh momentum to Nbis stock, but it did not start from zero. Nvidia invested $2 billion in Nebius in March, and the two companies have a strategic partnership aimed at accelerating cloud computing infrastructure for the AI market, with Nebius data centers running Nvidia GPUs and related hardware and software. That backdrop helps explain why Huang’s comments mattered so much to traders: they landed on a company already linked tightly to the dominant chipmaker in AI.
There was also a second reason investors were focused on the name. A regulatory filing showed that Situational Awareness acquired more than 12.4 million shares of Nebius, a position that would currently be valued at about $3.3 billion. The fund is led by former OpenAI researcher Leopold Aschenbrenner, and its own portfolio was worth roughly $13.7 billion as of March 31.
That new stake adds a layer of outside validation to a stock that was already surging on the back of Huang’s endorsement, but it also leaves an open question: how much of Monday’s record run came from Nvidia’s public praise, and how much came from the newly disclosed wager by Aschenbrenner’s fund. For now, Nebius has the kind of attention that can turn a routine trading day into a test of how far AI enthusiasm will carry a company already in Nvidia’s orbit.
