Treat business quality, execution risk and valuation as separate tests.
1. Verify what the company actually earns from AI
Start with the company’s latest annual and quarterly filings, earnings release and management discussion. Look for named AI products or services, the business segment in which they are reported, and any quantified revenue or margin contribution. Use the company’s own definitions, and check whether segment labels or reporting methods changed before comparing periods.
Separate an explicit AI revenue measure from a broader result—such as cloud, software or semiconductor sales—that management links to AI without quantifying AI’s share. If the company does not break out AI revenue or operating effects, say so; do not estimate a figure from a broad segment total.
The SEC recommends reviewing company disclosures as well as promotional campaigns, and using its EDGAR database to access public-company filings. See the SEC Investor.gov alert on AI and investment fraud.
#1 Best Overall
NVIDIA’s Form 10-Q illustrates why the distinction matters. For the three months ended July 26, 2026, the company reported $96.221 billion in total revenue and $89.023 billion in data-center revenue. The latter is a company-reported segment figure, not a statement that all data-center sales were AI revenue, and neither figure is a forecast. The same filing reported that one direct customer accounted for 16% of quarterly revenue; three customers accounted for 16%, 15% and 13% of revenue in the first half. Those disclosures help identify concentration, but do not by themselves establish how much revenue is specifically AI-related. See NVIDIA’s Form 10-Q.
2. Trace who pays—and where demand could break
Map the company’s place in the AI supply chain: chips, networking, cloud capacity, software, applications or end-user deployment. A supplier can benefit from infrastructure buildout without proving that end customers earn a return from AI. A software or application company may need to show that users adopt paid features, renew, or pay more for measurable value. The relevant demand evidence depends on the company’s role.
Use filings to ask:
- Who are the largest customers, and what share of sales do they represent?
- Are customers buying directly, or is demand flowing through cloud providers, resellers or other intermediaries?
- Could a few buyers delay purchases, switch suppliers or negotiate prices down?
- Do backlog, purchase commitments, leases or other obligations leave the company exposed if demand slows?
- Can customers finance their purchases and secure the power, land and data-center capacity needed to use what they buy?
Customer concentration can make reported growth dependent on a small number of purchasing decisions. NVIDIA’s filing says customers may defer purchases if infrastructure or capital is unavailable, or adopt new technologies more slowly than anticipated. It identifies land, power, data-center “shell” capacity and customer financing as possible constraints. These are risks management disclosed, not predictions that any constraint will occur.
3. Compare AI spending with cash generation and customer returns
Large investment announcements show intent, not realized returns. Compare capital expenditure and lease obligations with operating cash flow, free cash flow, depreciation, debt and other commitments. Then look for evidence that customers are using the capacity and paying for it: adoption, retention, pricing power, usage or documented cost savings. Management’s confidence and demand commentary are evidence of management’s view, not proof of return on investment.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Consider whether today’s infrastructure would remain useful if customer demand, model economics or chip generations changed. A company can spend heavily and still face a gap between the time it pays for capacity and the time it earns revenue from it. For a cloud provider, capacity constraints may limit sales; for a company that buys cloud services, rising infrastructure costs may pressure margins.
Microsoft management said on its FY2026 Q3 earnings call in April 2026 that it expected roughly $190 billion in calendar-year 2026 capital expenditures, including about $25 billion from higher component pricing, and expected capacity to remain constrained at least through 2026. This was forward-looking company guidance on that call—not an audited full-year result. Treat it as an illustration of both the scale of spending and the possibility that investment does not immediately translate into available capacity.
4. Check execution, disclosure and the risks behind the story
Read the risk factors in filings alongside management’s discussion of strategy and results. Relevant risks can include:
- Dependence on a small number of customers or suppliers
- Supply-chain constraints, export controls, or access to power and data-center infrastructure
- Financing needs, debt, leases and other long-term commitments
- Competition, intellectual-property disputes and rapid product changes
- Cybersecurity, privacy, model reliability, regulation and responsible-use concerns
- Slow customer adoption or difficulty turning pilots into paid, recurring use
Compare stated plans with later reported results: did the company deliver capacity, win customers, sustain margins or convert investment into cash? Disclosure quality matters because companies do not all report AI activity in the same way. The SEC Investor Advisory Committee’s December 2025 recommendation said AI-risk disclosure practices varied significantly across industries, making comparison harder. A missing quantified AI line item is a limit on what can be verified—not a reason to fill in the blank.
The recommendation cited outside studies with different scopes. It relayed Deloitte and USC Marshall School of Business’s 2024 finding that 60% of S&P 500 companies viewed AI as a material risk, across issues including cybersecurity, competition, innovation, regulation, intellectual property, ethics and reputation. It also cited Boston Consulting Group’s 2024 finding that 22% of companies had moved beyond proof of concept toward core-business integration or new revenue. Separately, it quoted MIT NANDA’s 2025 study reporting zero return at 95% of organizations in that study despite $30–40 billion in enterprise GenAI investment. These are attributed study results relayed in an advisory recommendation, not regulator findings about every company or investor.
5. Watch for promotion masquerading as evidence
Be cautious when a company’s AI pitch relies on buzzwords, guaranteed gains, urgency or endorsements instead of verifiable products, customers and financial disclosures. The SEC warns that AI claims can appear in pump-and-dump schemes and notes that microcap companies may offer limited public information about management, products, services and finances. Compare promotional claims with filings and with the disclosures of similar companies; EDGAR provides access to public-company filings.
The SEC’s Investor.gov alert offers a useful test: “If the company appears focused more on attracting investors through promotions than on developing its business, you might want to compare it to other companies working on similar AI products or services to assess the risks.” It also suggests asking: “Why is this person endorsing this investment, and does it fit in your financial plan?”

A credible AI business is not automatically an attractive stock at every price. Choose a valuation measure suited to the company, then compare price with earnings, cash flow, margins, reinvestment needs and balance-sheet risk. For a company whose current earnings are distorted by unusually high investment or cyclical conditions, use scenarios rather than relying on one point estimate.
Best Value
Build at least three cases and make the assumptions explicit:
- Downside: slower adoption, lower pricing or margins, delayed capacity, or spending that fails to earn an adequate return.
- Base: a plausible pace of adoption and monetization, with investment and margins developing as expected.
- Upside: faster paid adoption, stronger pricing or better cash conversion than the base case.
For each case, ask what revenue growth and margins would be needed to support the valuation, how much reinvestment that growth would require, and what could make the assumptions fail. Compare companies on reported AI-linked revenue and its definition, customer and supplier concentration, capital intensity, cash conversion, customer adoption, operational and regulatory risk, and valuation across the scenarios. No ticker or dated share price is specified here, so a current multiple, fair-value estimate or buy/sell conclusion cannot be established from these checks alone.
