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 is 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 roughly 250% gain over the past 12 months.
- Nvidia previously committed to investing $2 billion in Nebius as part of a deal 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 computing company built specifically to rent out AI computing power, rather than the older general-purpose cloud 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 Nebius to use its warehouses full of powerful chips instead of buying their own.
Nvidia had already announced a $2 billion investment in the Dutch firm. The two companies are working together on building AI infrastructure, managing large fleets of servers, running inference (the process of an AI model actually answering a question or completing a task), and designing so-called AI factories, which are large data centres optimised specifically for AI workloads.
Nebius stock has climbed roughly 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 is placing big bets across the AI industry right now. 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. But Nebius is part of the infrastructure that keeps AI tools running. More investment means more servers, which generally means faster, cheaper AI services down the line for everyone using them.
If you hold Nebius shares, Tuesday was a good morning. If you do not, this story is mainly a signal that the big players still believe AI infrastructure spending has a long way to go.
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.
