NBIS vs NVDA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. NBIS and NVDA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined NBIS and NVDA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Nebius Group is an AI infrastructure company that builds and operates cloud platforms optimized for training and running artificial-intelligence models. It emerged from the international assets of the former Yandex business after Yandex's Russian operations were divested, and it relisted on Nasdaq as a standalone company headquartered in Amsterdam. Nebius's core business is an AI-focused cloud: it builds data centers packed with NVIDIA GPUs and rents that compute capacity to companies training large AI models, competing with the GPU-cloud and neocloud providers that have grown alongside the AI boom. The company designs its own server hardware and software stack to deliver high-performance, cost-efficient AI compute. Beyond the core cloud, Nebius holds several other technology businesses, including an autonomous-driving unit, an edtech platform, and a generative-AI data-labeling business, plus a stake in a data-center and other ventures. As a relatively young public company, Nebius is in a heavy-investment phase, spending aggressively on GPU capacity and data centers to capture AI-infrastructure demand, and is not yet consistently profitable. Over the trailing twelve months to June 2026, Nebius reported ~$1.36 billion of revenue, a gross margin near 74% and roughly break-even operating results, while capital spending pushed free cash flow to about -$9.6 billion. The balance sheet carried ~$8 billion of cash against ~$10.2 billion of debt as of mid-2026.

NVIDIA (NVDA) designs the graphics processing units (GPUs) and the software stack that have become the standard compute platform for modern artificial intelligence. The company operates across four reporting segments. Data Center sells GPUs to the major cloud providers (Microsoft Azure, AWS, Google Cloud, Oracle, Meta) and to AI labs (OpenAI, Anthropic, xAI) for training and running large language models; it brought in about $89 billion of the $96.2 billion total in the quarter ended July 26, 2026, roughly 92% of revenue. Gaming covers GeForce consumer GPUs, NVIDIA's original core market. Professional Visualization sells workstation GPUs for design and simulation, and Automotive ships the DRIVE platform for assisted and autonomous driving. NVIDIA also builds CUDA, the proprietary software platform that lets developers write code that runs on its GPUs and that AI frameworks like PyTorch, TensorFlow, and JAX target first. Founded in 1993 by Jensen Huang, Chris Malachowsky, and Curtis Priem, headquartered in Santa Clara, California, and led by co-founder and CEO Jensen Huang, NVIDIA is the most valuable listed company in the world at about $5.25 trillion in mid-October 2026. It designs its chips and outsources manufacturing primarily to TSMC.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• NBIS drivers: AI compute demand tailwind; Vertically integrated, cost-efficient stack.
• NVDA drivers: Continued AI infrastructure dominance; Beyond hyperscalers: sovereign AI and enterprise.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Nebius is an early-stage, capital-intensive business: building GPU data centers requires enormous upfront spending, and free cash flow was about -$9.6 billion over the trailing year to June 2026. For NVDA, customer concentration is high: a handful of hyperscalers and AI clouds account for a large share of revenue, so any slowdown in their AI capex hits results directly, and some newer GPU-cloud customers carry heavy debt.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick NBIS if you believe its drivers more; NVDA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the NBIS and NVDA guides.

NBIS. Nebius trades at ~32 times trailing sales, a valuation that leans on analysts' expectations of ~$3.3 billion in 2026 revenue and ~$12.3 billion in 2027 rather than on current profits. The shares are up ~91% year to date but have fallen ~23% in the past month as financing costs for neoclouds came into focus, and the next report, due November 10, 2026, is expected to show revenue near ~$905 million with a loss of ~$0.65 per share.

NVDA. The trailing P/E of about 27.5x is far lower than the roughly 50x of early 2026, because earnings more than doubled while the stock rose about 15% this year; on next fiscal year's consensus EPS of about $15.91 the multiple is under 14x. The market still prices continued hyperscaler AI capex, 60%+ operating margins, and a CUDA software moat. The risk is symmetrical: if AI spending slows, estimates and the multiple can fall together. NVIDIA guided the October 2026 quarter to about $108 billion of revenue (consensus about $109 billion) and reports on November 17, 2026.

Headline figures (approximate, October 2026): NBIS shows revenue (ttm) ~$1.36 billion (to June 2026), revenue growth ~454% year over year in the June 2026 quarter (~$582 million), margins Gross ~74%; operating roughly break-even (~-0.2%), net income (ttm) ~$42 million, lifted by a large one-quarter gain in Q1 2026; NVDA shows revenue (ttm) ~$303 billion (+106% YoY in the July 2026 quarter), data center revenue (q2 fy2027) ~$89 billion, ~92% of revenue, operating margin (ttm) ~66%, exceptionally high for a hardware company, net income (ttm) ~$193 billion.

NBIS and NVDA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
