Nebius Group (NASDAQ: NBIS), a resurgent AI infrastructure player, is much more than its core cloud business. With a significant 28% ownership stake in the high-growth data analytics firm ClickHouse, poised for an IPO, and a substantial 28% economic interest in the recently Jeff Bezos-backed AI data specialist Toloka, Nebius is strategically diversified and positioned for substantial long-term value creation in the burgeoning artificial intelligence sector.
In the rapidly expanding universe of artificial intelligence, a few companies stand out not just for their direct contributions but also for their strategic stakes in other high-potential ventures. Nebius Group (NASDAQ: NBIS), which saw its stock surge over 618% in the past year due to insatiable demand for cloud computing capacity, is one such entity. While its core business in AI infrastructure is robust, a closer look reveals a diversified portfolio of AI-related assets that could unlock significant shareholder value, particularly its holdings in ClickHouse and Toloka AI.
Nebius Group’s Strategic Rebirth and Core Business Foundation
Nebius Group’s journey to becoming a prominent AI infrastructure company is rooted in a significant corporate restructuring. Emerging from the divestment of Yandex N.V.‘s Russian and Russia-related assets, Nebius Group N.V. officially relocated its headquarters to Amsterdam and resumed trading on the Nasdaq Stock Exchange on October 20, 2024, after a trading halt since February 2022. This move marked a clean break from its past, allowing it to focus entirely on its international AI ambitions.
At its heart, Nebius is a full-stack technology company providing critical infrastructure for the global AI industry. This includes large-scale GPU clusters, cloud platforms, and specialized tools for AI developers. The company boasts proprietary cloud software architecture and in-house designed hardware, covering everything from servers and racks to data center design. Its state-of-the-art data center in Finland, for instance, operates with exceptional energy efficiency, consistently achieving a Power Usage Effectiveness (PUE) below 1.2, significantly lower than the global average of 1.58 in 2023. This facility houses approximately 14,000 GPUs, with substantial capacity for expansion.
Financially, Nebius presents a compelling profile. As of September 30, 2024, the company reported over $2 billion USD in cash on its balance sheet with zero debt. The core AI infrastructure business is projected to deliver an Annualized Run-Rate Revenue (ARR) of $500 million to $1 billion by the end of 2025. This growth is backed by a team of approximately 400 experienced AI, ML, software, and cloud engineers, many of whom have been with the company since its inception. Nebius’s full-stack expertise and optimized operations translate into a 20-25% lower total cost of GPU ownership and operations compared to average providers, giving it a significant competitive advantage in the market.
ClickHouse: A Rising Star Poised for IPO with Nebius’s Stake
Beyond its core cloud offerings, Nebius Group holds a significant 28% ownership stake in ClickHouse, an artificial intelligence startup gaining considerable traction. ClickHouse originated as an in-house project at Yandex before being successfully spun off in 2021. Initially valued at $2 billion in its second financing round that same year, ClickHouse’s valuation soared to $6.35 billion in May 2025, following a $350 million Series C funding round. This round was recently extended to include new investors like Citi Ventures and Insight Partners, alongside individual investors from the San Francisco 49ers, highlighting its growing appeal.
ClickHouse is an AI data company renowned for its real-time analytics, machine learning, and generative AI capabilities, along with robust data warehousing solutions. Its strength lies in its ability to store, sift through, and search massive amounts of data with lightning-fast query experiences. This makes it invaluable for high-profile customers like Instacart, which leverages ClickHouse for instantaneous fraud detection, retailer dashboards, A/B testing, and machine learning signals. The company has surpassed 2,000 customers, including major players such as Hewlett Packard, Cyera, ShopMonkey, Canva, Anthropic, and Meta Platforms, and has more than quadrupled its annual recurring revenue over the past year. The CEO of ClickHouse, Aaron Katz, has openly expressed the company’s interest in pursuing an Initial Public Offering (IPO) once its technology achieves a certain scale and unit economics, a move that would significantly benefit Nebius Group’s valuation of its stake. This strategic positioning in a potentially IPO-bound, high-growth AI data company underscores Nebius’s foresight in recognizing foundational AI technologies, as reported by The Motley Fool.
Toloka AI: The Jeff Bezos Backing and Nebius’s Strategic Economic Interest
Adding another layer to Nebius’s diversified strategy is Toloka AI, a leading AI data labeling and evaluation platform. In May 2025, Toloka received a significant boost with a $72 million strategic funding round led by Jeff Bezos’s investment firm, Bezos Expeditions. As part of this deal, Nebius Group strategically relinquished majority voting control of Toloka, allowing it greater operational freedom and direct access to dedicated capital and strategic partnerships. However, Nebius retains a substantial 28% economic interest, ensuring it benefits from Toloka’s future growth and success.
Toloka is critical to the AI lifecycle, providing high-quality expert data for training, aligning, and evaluating large-scale AI models. Its services are essential for companies building generative AI tools, supporting everything from chatbots to autonomous vehicles. With a global network of over 200,000 contributors across 100+ countries and 40 languages, Toloka serves enterprise clients like Amazon, Anthropic, Microsoft, and Shopify. The market reacted positively to the news of Bezos’s investment, with NBIS stock surging over 26% in the week following the announcement, reflecting investor confidence in Nebius’s strategic capital allocation and its ability to incubate and spin off valuable assets.
Expanding the AI Ecosystem: AV Ride and TripleTen
Nebius Group’s investment tapestry extends further to include other innovative businesses under its umbrella: AV Ride and TripleTen.
- AV Ride: This autonomous vehicle division is developing self-driving technology for both cars and delivery robots. AV Ride recently secured a multi-year strategic partnership with Uber for both mobility and delivery services. Plans are underway to launch sidewalk delivery robots in Austin in the near future, with ambitions to expand the fleet to hundreds in 2025 and introduce robotaxi services.
- TripleTen: A leading edtech platform specializing in reskilling individuals for successful careers in tech. Primarily focusing on the US and Latin American markets, TripleTen was recognized as the best overall software engineering bootcamp in the US by Fortune magazine in June 2024, showcasing Nebius’s commitment to bridging the tech skills gap and fostering social inclusion within the AI ecosystem.
Investment Outlook and Community Perspectives on Nebius Group (NBIS)
From the perspective of a fan community focused on in-depth financial analysis, Nebius Group represents a compelling, though speculative, investment opportunity. Many investors believe it is an “under-covered AI infrastructure company” that should be receiving more attention, especially given the seemingly limitless demand for AI compute resources. The company’s clean balance sheet, with over $2 billion in cash and no debt, provides significant flexibility for its ambitious investment program, which anticipates capital expenditures of $600 million to $1.5 billion in 2025 for data center expansion and operations.
Key attractions for investors include Nebius’s direct exposure to burgeoning AI compute trends, its experienced CEO Arkady Volozh (co-founder of Yandex), and the cost advantages of its Finland data center. Furthermore, the strategic stakes in high-growth private companies like ClickHouse and Toloka provide significant “optionality” and potential for future value accretion, distinguishing Nebius from pure-play data center operators. The company’s commitment to high standards of corporate governance and sustainability also resonates with long-term investors.
However, the investment is not without its risks. Community discussions often highlight the uncertainty of future demand for AI compute, the potential for over-building infrastructure, and intense competition from trillion-dollar cloud service providers. The capital intensity of data center construction and maintenance, along with potential power limitations, are also noted concerns. Moreover, a historical “Russian overhang” from its Yandex origins might influence market perception, potentially preventing the stock from being awarded an “AI-like” multiple on sales or EBITDA, as discussed in various investment forums.
Despite these risks, the current market sentiment remains highly favorable towards AI infrastructure providers. If Nebius successfully executes its expansion plans and achieves its projected ARR targets, it is positioned to be a significant winner. The diversified portfolio, with a core AI cloud business complemented by stakes in innovative AI data and autonomous driving ventures, offers a robust long-term investment thesis for those willing to embrace a calculated level of speculation. The company’s strategic moves, like the Toloka spin-off and the potential IPO of ClickHouse, illustrate a dynamic approach to value creation that could lead to substantial returns for patient investors.
