Nebius, the AI infrastructure company that spun out of Russian internet giant Yandex, is extending its rally. The stock has been on a tear this year, and the latest boost comes from a significant partnership with Palantir, the data analytics firm. For investors, the move underscores how deeply the AI boom is reshaping the tech landscape—and why Nebius has become a favorite way to play it.
What's driving Nebius higher?
Nebius provides the heavy-duty computing power that AI developers need—think cloud services, data centers, and specialized chips. As more companies rush to build and deploy AI models, demand for this kind of infrastructure has skyrocketed. That's why Nebius shares have climbed so sharply in 2025.
The new deal with Palantir is a big deal. Palantir is known for its software that helps organizations analyze massive amounts of data, often for government and defense clients. By teaming up, the two companies can offer a more complete package: Palantir's analytics tools running on Nebius's powerful cloud. That combination could attract customers who want to harness AI without building their own expensive infrastructure.
This isn't just a one-off win. It signals that Nebius is becoming a go-to partner for established tech players, not just a startup with promise. For everyday investors, that's a sign the company's growth story has legs.
The AI trade is leading the pack
Nebius's performance is part of a broader trend. Looking back at two years of portfolio picks, the pattern is clear: AI-related stocks are the standout winners. Among the 18 ideas tracked, the three best-performing open positions are all AI plays, and they've gained an average of 100% this year alone. That's a remarkable return, especially compared to the average gain of 35% across all 18 picks.
To put that in perspective, eight of the 18 picks have been winners, rising an average of 89.9%. Eight have been losers, falling an average of 11%, and two have been roughly flat. The AI names are clearly the engine of the portfolio's success.
This isn't just about Nebius. The entire AI sector has been on a tear, from chipmakers to cloud providers. But Nebius stands out because it's a pure-play infrastructure company—it doesn't make consumer gadgets or sell software subscriptions. It's directly tied to the physical and digital backbone that AI needs.
What it means for investors
For everyday investors, the Nebius rally is a reminder that AI is not just a buzzword—it's driving real revenue and profits for companies that provide the underlying technology. But it also comes with risks. Stocks that rise this fast can be volatile, and a single piece of bad news—a missed earnings estimate, a slowdown in AI spending, or increased competition—could send shares tumbling.
That's why it's important to think about diversification. While AI has been a winning bet, no single sector should dominate your portfolio. The broader market has other opportunities, from rising crop prices to memory chip costs that are affecting consumer electronics. Keeping a mix of assets can help smooth out the bumps.
Also, consider the valuation. When a stock doubles in a year, it's natural to wonder if the good times can last. Nebius's partnership with Palantir adds credibility, but it doesn't guarantee future growth. Investors should watch how the company executes on its expansion plans and whether it can turn its infrastructure into steady profits.
Looking ahead
For now, the AI case for Nebius looks stronger than ever. The Palantir deal is a vote of confidence from a major player, and the company's infrastructure is in high demand. But as with any high-flying stock, it's wise to stay informed and not chase momentum blindly.
If you're considering adding Nebius to your portfolio, think about your own risk tolerance and time horizon. AI is likely to be a major theme for years, but that doesn't mean every AI stock will be a winner. Do your research, understand the business, and consider how it fits into your overall strategy.
In the meantime, the broader market continues to offer other stories worth watching, from data center IPOs to oil price movements. But for investors focused on growth, Nebius remains a name to keep on the radar.
