Nvidia Reveals a 9.3% Stake in Nebius, and the Stock Jumps 7%
The chip giant is backing Europe's fastest-growing AI cloud company with real money. Here's what that means and why investors are paying attention.
Key points
- Nvidia disclosed a 9.3% ownership stake in Nebius, an Amsterdam-based AI cloud company listed on the Nasdaq stock exchange.
- Nebius shares rose 7% in premarket trading on Tuesday, adding to a nearly 250% gain over the past 12 months.
- Nvidia had previously committed to investing $2 billion in Nebius, covering AI infrastructure and cloud services.
- Meta signed a separate long-term agreement in March 2026 to spend up to $27 billion on Nebius infrastructure.
- Nebius held a market capitalisation of $46 billion as of Tuesday morning.
Nvidia, the chip company whose processors power almost every major AI system on the planet, has revealed it owns 9.3% of Nebius. Nebius is a neocloud, meaning a newer type of cloud company built specifically to rent out AI computing power rather than the general-purpose services offered by Amazon or Microsoft. The news, first reported by CNBC Tech, sent Nebius shares up 7% before the market even opened on Tuesday.
What exactly is Nebius, and why does Nvidia want a piece of it?
Nebius is one of Europe's largest providers of AI computing infrastructure. Think of it as a landlord for AI: companies pay to use its warehouses full of powerful chips instead of buying their own. We've followed Nebius since our first story on 14 July 2026, and Tuesday's disclosure is the sharpest sign yet of how tightly Nvidia is binding itself to its biggest customers.
Nvidia had already announced a $2 billion investment in the Dutch firm. The two companies are working together on AI infrastructure deployment, fleet management, inference (the process of an AI model actually answering a question or completing a task), and designing AI factories, which are large data centres optimised for AI workloads.
Nebius stock has climbed nearly 250% over the past 12 months. Its market cap sat at $46 billion on Tuesday morning.
Is Nvidia doing this everywhere, or is Nebius special?
Nvidia's placing big bets across the AI industry. The company contributed $30 billion to the $110 billion funding round that OpenAI announced in March 2026, and it participated in Anthropic's $30 billion raise in February 2026. Taking a near-10% stake in Nebius fits the same pattern: back the companies most likely to buy enormous quantities of Nvidia chips.
Meta added its own vote of confidence in March 2026, signing a long-term deal to spend up to $27 billion on Nebius infrastructure.
| Event | Amount | Date |
|---|---|---|
| Nvidia investment in Nebius | $2 billion | Announced 2026 |
| Nvidia stake in Nebius | 9.3% | Disclosed Tuesday |
| Meta infrastructure deal with Nebius | Up to $27 billion | March 2026 |
| Nvidia contribution to OpenAI round | $30 billion | March 2026 |
| Nvidia participation in Anthropic raise | Part of $30 billion round | February 2026 |
What does this mean for ordinary people?
Directly, not much today. Nebius is part of the infrastructure that keeps AI tools running, so more investment generally means more servers and, eventually, faster, cheaper AI services for everyone using them.
Tuesday was a good morning if you hold Nebius shares. If you don't, this is mainly a signal that the biggest players still think AI infrastructure spending has a long way to run. Worth watching: our 22 July story on AMD's Helios raised the question of whether Nvidia's grip on data-centre chips is as secure as deals like this one suggest.
Common questions
Is Nebius a safe investment after this news?
Stock prices can move fast on announcements like this, and a 250% rise in 12 months means a lot of good news is already priced in. Consider that a caution, not a prediction.
Does Nvidia owning a stake affect the chips Nebius uses?
Nebius already relies heavily on Nvidia hardware, so this is less a change in direction and more a formal financial tie to a relationship that already existed.
