Innodata vs. Nebius Group N.V.: Which AI Stock Is a Better Buy in 2026?

The race to build generative artificial intelligence has shifted the spotlight from chipmakers toward the specialized firms providing the data and infrastructure needed to train massive models. Investors are currently weighing Innodata Inc (NASDAQ:INOD) and Nebius Group N.V. (NASDAQ:NBIS) as potential winners.

Innodata focuses on the human expertise and data engineering required to refine model outputs, while Nebius Group provides the underlying high-performance cloud infrastructure. Both companies occupy critical niches in the evolving artificial intelligence landscape, but offer very different financial profiles for long-term investors to consider.

The case for Innodata

Innodata is a global data engineering firm that provides the evaluation frameworks and human expertise necessary to deploy trusted artificial intelligence systems. Within the tech stocks landscape, it serves five of the "Magnificent Seven" technology giants and recently deepened its collaboration with Meta Platforms (NASDAQ:META) regarding AI data services. In its latest annual report, filed for FY 2025, the company highlighted its global workforce of over 6,000 professionals.

Financial performance has been robust as demand for model training data accelerates. In FY 2025, revenue reached nearly $252 million, representing growth of close to 48% over the previous year. The company reported net income of approximately $32.2 million, resulting in a net margin of roughly 13% for the fiscal year.

As of its December 2025 balance sheet, the debt-to-equity ratio is 0.0x, a measure of total debt relative to shareholders' equity that indicates the company is debt-free. Its so-called current ratio is roughly 2.7x, and free cash flow reached nearly $36 million. Note that stock-based compensation accounted for roughly 24% of operating cash flow, inflating reported cash generation because it is a non-cash add-back.

The case for Nebius Group N.V.

Nebius Group N.V. positions itself as a full-stack cloud infrastructure provider, helping start-ups and enterprises manage the entire model lifecycle. The company is aggressively expanding its footprint across North America and Europe, serving a global market of start-ups and large enterprises. By offering high-performance GPU clusters and model training environments, it aims to compete directly with the world's largest cloud service providers.

Growth has been explosive during the most recent fiscal period as the company established its new operational foundation. In FY 2025, revenue reached nearly $530 million, a massive increase of about 350% year over year. Net income for the period was approximately $102 million, yielding a net margin of roughly 19% as the company scales its operations.

As of its December 2025 balance sheet, the debt-to-equity ratio was nearly 1.1x, indicating the company uses slightly more debt than equity to fund its assets. Its current ratio is roughly 3.1x, but heavy capital spending led to a free cash flow loss of nearly $3.7 billion. Note that stock-based compensation accounted for roughly 21.6% of operating cash flow, inflating reported cash generation because it is a non-cash add-back.

Risk profile comparison

Innodata faces significant revenue concentration, with one major customer accounting for nearly 58% of its total revenue in 2025. This reliance means any change in that relationship could severely impact the business. Furthermore, the company competes with specialized firms like Appen and faces a pending securities class action lawsuit related to its technology disclosures.

Nebius Group operates in a capital-intensive industry where it must spend billions on hardware to stay competitive. It faces competition from massive hyperscalers like Amazon.com Inc (NASDAQ:AMZN) and Microsoft Corp (NASDAQ:MSFT), who have vastly larger balance sheets. Additionally, scaling global data centers across different regulatory environments carries inherent execution and geopolitical risks for the firm.

Valuation comparison

Nebius Group carries a lower earnings multiple based on future earnings estimates, while Innodata trades at a much lower multiple of its sales over the past twelve months.

Which stock would I buy in 2026?

Nebius Group is a newcomer to AI. It used to be part of the Russian Internet giant Yandex. It was split from Yandex to separate the Russian (Yandex) parts of the business from the non-Russian (Nebius) parts. That left Nebius with a lot of cash and a few unconnected businesses. It was just last year, 2025, that Nebius decided to go all-in on AI, electing to use its large cash pile to buy up thousands of top-tier chips from Nvidia Corp (NASDAQ:NVDA) and turn itself into a hyperscaler. The audacious move paid off, with annual sales topping $500 million last year. The year prior, before it dove into AI, it sold less than a fifth of that.

Nebius is projected to make $3.3 billion in sales in 2026, then an astonishing $12 billion in 2027, and $23 billion the year after. Nebius projects that the prices of the services and hardware it provides to hyperscalers will continue to rise. Management says its market share is perhaps 5% to 10%, which means there is space to capture more of a massive market.

Innodata has been moving to assuage customer concentration worries, reducing dependence on its two biggest customers as a percentage of sales by adding new customers, including one of the most significant operators in frontier AI, according to management.

Among enterprises, Innodata sees companies quick to develop AI agents but struggling to deploy them in production with confidence. The company believes that combining its trusted observability platform and its innovatively architected reinforcement learning gyms enables Innodata to position itself as the AI deployment assurance layer. It's a position that management says is opening up a huge long-term opportunity.

That said, it is a slower grower than Nebius. In fiscal 2026, revenue is seen advancing 43% year over year to $360 million, with net income around $43 million. Those are good figures, but they don't approach the scale and growth of Nebius. Even though it has a high P/S ratio, Nebius's lower forward P/E means it's the better buy among these two AI-focused businesses.
