Start with company-reported results, label AI-related segments carefully, then add a dated share price before calculating valuation. Strong growth alone does not mean a stock is attractively valued.
What counts as an AI stock?
“AI stock” is not a uniform business category. A company may sell accelerators used to train AI models, provide cloud infrastructure, or incorporate AI into a broader software business. Companies also define and report their segments differently. Treat AI exposure as a description of a company’s products and customers—not as a directly comparable accounting category unless the companies themselves define it that way.
For each company, identify which disclosed products or segments are relevant to AI, and distinguish those figures from total company results. A segment described as AI-relevant may include other products or demand drivers; do not relabel it as exclusively AI revenue unless the company does so.
How to compare growth
Use the same kinds of measures for each company: total revenue growth and growth in a clearly identified AI-relevant segment, over specified reporting periods. Include the period end date and whether a figure is quarterly or annual. Fiscal years differ, so do not assume that companies’ “FY2025” results cover the same dates.

The following disclosures illustrate why the labels and periods matter. They are company-reported results, not forecasts, and the figures should not be treated as a directly comparable ranking.
| Company and period | Total company result | AI-relevant disclosed result | Important context |
|---|---|---|---|
| Microsoft, FY2025 ended June 30, 2025 | $281.7 billion revenue, up 15%; $128.5 billion operating income, up 17%. | Microsoft Cloud revenue was $168.9 billion, up 23%; Azure revenue was above $75 billion, up 34%. | Cloud and Azure are relevant indicators, but neither figure is identified here as exclusively AI revenue. Source: Microsoft 2025 Annual Report. |
| AMD, FY2025 ended December 27, 2025 | $34.6 billion revenue, up 34%. | Data Center revenue was $16.6 billion, up 32%. | AMD attributed Data Center growth primarily to demand for EPYC processors and Instinct GPUs; the segment is not described as solely AI revenue. Source: AMD 2025 Form 10-K. |
| NVIDIA, fiscal 2026 fourth quarter and full year | Full-year revenue was $193.7 billion, up 68%. | Quarterly Data Center revenue was $62.3 billion, up 75% year over year. | The quarterly segment figure and full-year company figure cover different periods. NVIDIA’s release said its outlook assumed no Data Center compute revenue from China. Check the release for its stated reporting dates before making period comparisons.

Growth rates are a starting point, not a complete measure of business quality. Compare margin direction as well, while keeping company-specific definitions intact. For example, AMD reported a 50% gross margin in FY2025 versus 49% in FY2024. Its filing also described product-mix effects and approximately $440 million in net inventory and related charges associated with U.S. export controls on MI308 data center GPU products.

How to compare valuation
Valuation requires both a market price and a financial denominator. Choose and date the share price or market capitalization, then state the earnings or sales period used. A price-to-earnings ratio relates share price to earnings per share; enterprise-value-to-sales relates enterprise value to revenue. These measures answer different questions and should not be mixed without explanation.
- Set a market-data date. Record the share price or market capitalization and the date it represents. If comparing companies, use a consistent date.
- Name the denominator. Specify whether earnings or sales are trailing, for a fiscal year, or an estimate. Do not compare a trailing figure for one company with a forecast for another without clearly labeling the difference.
- Calculate consistently. Use the same valuation method and accounting basis across the companies where possible. Explain material differences in fiscal periods or definitions.
- Interpret the result alongside growth and risk. A higher multiple may reflect expectations of faster growth, but it can also leave less room for disappointment. A lower multiple does not by itself establish that a stock is cheap or that its risks are lower.
The company reports cited above do not provide a matched current share-price set or current comparable multiples. The examples therefore support an operating-growth comparison, not a current valuation ranking. Any live multiple comparison needs dated market data and explicitly matched financial periods.
How to assess risk
Use company disclosures to identify risks that could affect growth, margins, or the ability to deliver products. Separate company-specific exposures from issues shared across the sector.
- Competition: Microsoft describes software, devices, and cloud-based services markets as “dynamic and highly competitive.” Consider whether a company’s products must defend share against established rivals, new offerings, or alternatives. Source: Microsoft 2025 Annual Report.
- Infrastructure costs and capacity: AI services require investment in infrastructure. Microsoft warns: “The investments we are making in cloud and AI infrastructure and devices will continue to increase our operating costs and may decrease our operating margins.” Growth can therefore coincide with pressure on costs and margins, while capacity constraints can limit how quickly demand is served.

- Suppliers, supply, and energy: Assess whether a company can obtain the components and energy needed to meet demand. NVIDIA’s quarterly filing identifies supply and demand management and energy-capacity constraints as possible sources of revenue volatility. Source: NVIDIA quarterly filing.
- Product transitions and customer timing: A new product generation can create execution complexity, and customers may adopt products on a different timetable than expected. NVIDIA’s quarterly filing identifies product-transition complexity and customer adoption timing as possible sources of revenue volatility. Source: NVIDIA quarterly filing.
- Government policy and export controls: Policy changes can affect which products may be sold in particular markets and can create costs tied to inventory or product availability. AMD’s FY2025 filing describes inventory and related charges associated with U.S. export controls on MI308 data center GPU products. NVIDIA’s FY2026 results release said its outlook assumed no Data Center compute revenue from China. Sources: AMD 2025 Form 10-K; NVIDIA fiscal 2026 results release.
Put the comparison together without forcing a winner
A useful comparison presents growth, valuation, and risk as separate lenses before discussing their trade-offs. This keeps a fast-growing business from being mistaken for an automatically attractive stock, and prevents a single multiple or risk factor from standing in for the whole analysis.
- Growth: Compare total revenue and the relevant disclosed segment over clearly dated, aligned periods.
- Business quality: Add margin direction and evidence about product breadth or customer adoption, noting that segment and margin definitions differ.
- Valuation: Pair a dated market price or capitalization with a named earnings or sales measure for a stated period.
- Risk: Record the company’s disclosed competitive, capital, supply, transition, adoption, and policy exposures.
- Trade-offs: Explain what supports growth and what might weaken it, then consider whether the price reflects expectations that could prove difficult to meet.
Microsoft CEO Satya Nadella wrote in the FY2025 shareholder letter: “More than any transformation before it, this generation of AI is radically changing every layer of the tech stack, and we are changing with it.” That is management’s view of the technology shift, not evidence that any one company will capture a particular share of its value.
