Nebius Rallies on AI Buildout and ClickHouse Stake

Nebius Group is emerging as one of the market’s most interesting asymmetric bets on the AI infrastructure buildout, with a rally in the stock reflecting not just demand for GPU cloud capacity but the value of its underappreciated assets, especially its large stake in ClickHouse.
That matters because the AI trade is increasingly shifting from front-end model hype to the plumbing that actually makes the ecosystem work. Investors are paying up for the picks-and-shovels layer — compute, storage, observability, networking and developer tooling — and Nebius is sitting in the middle of that stack through its neocloud business, its international expansion and its embedded equity in one of the fastest-growing infrastructure software names in the market.
The stock rose 2.6% in recent trading, extending a run that has already been dramatic this year, as the market continues to re-rate AI infrastructure names that can prove they are more than simple GPU lessors. Nebius is trying to do exactly that. It is building out sales and marketing in Korea, where it has begun local hiring and is preparing a Seoul hackathon with Nvidia and the Korean AI community Bloom, a sign the company wants to turn developer awareness into long-term enterprise demand before a formal local launch.
That expansion matters economically because the next phase of AI demand is not just about who can buy chips — it is about who can secure access to them, package them into usable services and distribute them into regions where governments and startups are racing to build domestic AI capacity. In that environment, Nebius is positioning itself as a regional infrastructure provider with a global footprint, rather than a one-off beneficiary of a cyclical GPU shortage.
The deeper bull case comes from ClickHouse. Nebius owned roughly 28% of the company as of May 2025, and even after dilution from ClickHouse’s January financing, the stake is still widely estimated to be worth several billion dollars. That makes ClickHouse a meaningful hidden asset inside Nebius, one that the market can easily underprice when it focuses only on operating revenue. ClickHouse itself is now one of the hottest names in AI infrastructure software, with annual recurring revenue above $350 million and a customer list that includes major enterprise users.
The strategic importance of ClickHouse goes beyond valuation math. Its growth reflects the broader explosion in data generated by AI workloads, especially agentic systems that create far more unpredictable database demand than traditional software. As AI agents proliferate, they will generate more queries, more observability data and more infrastructure spend. That is the kind of second-order tailwind Nebius investors want exposure to: not just the infrastructure used by AI today, but the infrastructure required by the workloads AI creates tomorrow.
Nebius also has support from Nvidia, which holds a 9.3% stake and has backed a $2 billion investment program. That relationship gives Nebius credibility with the market and with customers, while also tying it more closely to the industry’s dominant hardware supplier. In a sector where capital intensity, supply access and customer trust all matter, that kind of alignment can be worth more than a simple valuation multiple.
The investment case is therefore not just that Nebius is a neocloud player riding AI capex. It is that the company owns a portfolio of assets — GPU infrastructure, international market access and a material stake in a breakout data infrastructure business — that could compound together as AI spending broadens from model training into inference, observability and agentic software. The market often pays the highest multiples to the obvious names in the chain, but the most attractive returns can come from the holdings and enablers one layer down.
With AI infrastructure spend still expanding globally and capital flowing toward companies that can prove durable demand, Nebius looks set up as a leveraged way to play the theme. If management executes on Korea, monetizes its platform and the value of ClickHouse continues to compound, investors may look back on today’s share price as a point when the market was still too focused on the obvious and not enough on the hidden engine underneath.
