Nvidia just made its relationship with Nebius Group official, at least on paper. The chipmaker filed a Schedule 13G on July 13, 2026, disclosing a 9.3% beneficial ownership stake in Nebius, the Amsterdam-based AI cloud infrastructure company listed on the Nasdaq. The market responded the way it usually does when Nvidia puts its name on something: Nebius shares rose between 2.5% and 4.6% in after-hours trading on July 20, with momentum carrying into premarket the following morning.

This is not a sudden romance. The stake traces back to a $2 billion investment Nvidia made in Nebius on March 11, 2026, a deal structured around building out serious compute capacity for the AI era.

What Nvidia actually owns

The 9.3% stake breaks down into two components. Nvidia holds approximately 1.19 million Class A ordinary shares outright, plus an additional 21.07 million shares accessible through a pre-funded warrant, bringing the total position to roughly 22.25 million shares.

The filing itself is a Schedule 13G, which is the SEC’s standard form for passive investors disclosing ownership above 5%. It signals that Nvidia is not trying to take control of Nebius or direct its strategy, at least not formally.
