Nebius, the Amsterdam-based company that rents out computing power for artificial intelligence, delivered a blockbuster earnings report that sent its shares sharply higher and caught a number of high-profile short-sellers off guard. The company's revenue surged 454% year-over-year in the latest quarter, easily beating analyst expectations.
The stock's rally was a painful reminder that betting against a company riding the AI wave can be a risky proposition. Several well-known investors who had taken short positions—essentially wagering that the stock would fall—were forced to cover their positions as the price climbed, adding further fuel to the rally.
What is Nebius?
For those unfamiliar, Nebius is what's often called a "neocloud" provider. Unlike the giant public clouds from Amazon, Microsoft, or Google, Nebius focuses specifically on providing high-performance computing infrastructure for AI workloads. Companies developing and training large language models and other AI systems rent Nebius's servers and data centers rather than building their own.
This niche has become one of the hottest corners of the technology sector, as businesses across every industry race to adopt AI. The demand for specialized chips, like those from Nvidia, and the data centers to house them has exploded, and companies like Nebius are positioned to profit from that boom.
The earnings breakdown
Nebius's Wednesday report showed that its core cloud business grew more than 500% compared to the same period last year. That's a staggering pace of growth, even for a company in the high-growth AI sector.
Perhaps even more telling for the future, the value of new contracts signed during the quarter nearly quadrupled from the previous quarter. This suggests that demand for Nebius's compute is not just strong today but accelerating, as customers commit to longer-term deals.
The company also highlighted that it has landed several billion-dollar contracts, a sign that its largest customers are scaling up their AI ambitions. This kind of forward-looking metric is often what investors focus on most, as it provides visibility into future revenue.
Why the short squeeze?
Short-sellers borrow shares and sell them, hoping to buy them back later at a lower price and pocket the difference. When a stock rises instead, they are forced to buy back shares to limit losses, which can push the price even higher—a phenomenon known as a short squeeze.
Nebius had attracted a notable group of short-sellers, including some famous names in the investing world. They likely believed the stock was overvalued given the intense competition in the AI infrastructure space and the heavy capital expenditures required. But the earnings report showed that Nebius is executing well, and the market rewarded it.
For the short-sellers, the surge meant significant losses. It's a reminder that even the most sophisticated investors can be wrong, especially in a market where sentiment and momentum can be powerful forces.
What it means for investors
For everyday investors, the Nebius story is a case study in the opportunities and risks of the AI trade. On one hand, the explosive growth in AI infrastructure spending is real, and companies that provide the "picks and shovels" for AI—like Nebius—are seeing tangible revenue gains. This is not a hype-driven story; the numbers are there.
On the other hand, the stock's valuation is likely stretched, and the competitive landscape is intense. Giants like Amazon and Microsoft are also investing heavily in AI infrastructure, and they have deep pockets. Nebius will need to keep executing flawlessly to justify its current market value.
For those considering an investment in Nebius or similar companies, it's important to understand that volatility is part of the package. Stocks in high-growth sectors can swing wildly on earnings reports, and short squeezes can amplify moves in both directions.
The broader market context also matters. Inflation data and interest rate expectations have been driving sentiment across tech stocks. As we've seen in recent sessions, AI infrastructure earnings have helped lift the Nasdaq, while cooling inflation has supported stocks. But rising oil costs could keep inflation worries alive, and the latest CPI data left rate bets unchanged.
Investors should also keep an eye on the company's ability to secure the chips and energy needed to expand its data centers. Supply chain constraints could limit growth, and any hiccup could hit the stock.
Ultimately, Nebius's earnings show that the AI boom is translating into real revenue for infrastructure providers. But as with any high-flying stock, caution is warranted. Diversification and a long-term perspective remain the best tools for navigating such volatile waters.
