TL;DR
Six indicators in the October 28 preview show a strong but uneven AI boom: SK hynix reported record quarterly revenue and operating profit, while U.S. earnings growth relies heavily on two companies and major technology firms are preparing large capital budgets. Spending, cash flow and market concentration leave the investment payoff uncertain; Microsoft, Alphabet and Amazon results were still pending when the source was written.
SK hynix reported record third-quarter revenue and operating profit on October 28, while a steep selloff in Chinese AI and chip stocks and heavy planned spending by U.S. technology companies illustrated how uneven the AI boom has become. The figures offer a snapshot of strong demand for AI hardware, but leave open whether cloud companies can earn enough from AI services to justify their investment. Microsoft, Alphabet and Amazon had yet to report their results when the preview was published.
SK hynix said preliminary, unaudited third-quarter revenue reached 104.6 trillion won, up 328% from a year earlier, and operating profit was 83.3 trillion won, up 632% from 11.4 trillion won. Its operating margin was 80%. Net profit, however, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items. The results show how lucrative sales of high-bandwidth memory for AI processors have become, while also showing that operating profit and net profit can move differently.
The preview identified concentration as a second test. FactSet’s October 19 analysis estimated that Micron and Nvidia together account for much of expected S&P 500 earnings growth: excluding them, the third-quarter growth estimate fell from 29.0% to 20.0%. Those figures were estimates, and several major companies had not yet reported. FactSet’s blended estimate for S&P 500 earnings growth was 29.5% as of October 23.
Spending and cash generation formed another part of the check. Alphabet, Amazon, Microsoft and Meta had indicated combined 2026 capital spending of about $725 billion to $745 billion, according to the source’s calculation from company guidance. Analysts expected Alphabet and Amazon to post negative free cash flow again for the third quarter. Separately, U.S. core capital-goods shipments rose 1.2% in September, and orders for computers and related products were up 20.3% for the year, according to Census Bureau data cited in the preview.

Hardware Profits, Cloud Payback
The figures capture different stages of the AI investment cycle. Chip and memory suppliers are recording immediate sales and profits, while cloud providers are spending heavily on data centers and equipment in anticipation of demand. That gap matters to investors because large capital budgets can pressure cash flow before new services generate enough revenue to cover them.
Concentrated earnings growth also means headline market results may depend on a small number of companies. FactSet’s calculation still showed 20% S&P 500 growth after excluding Micron and Nvidia, a substantial estimate in its own right, but the gap illustrates how much the two chipmakers influence the aggregate. The figures do not establish that AI spending will fail to pay off; they show why revenue growth, cash generation and future capacity plans are key measures to watch.
Market performance in China provides a contrasting signal. Reuters reported that the STAR50 index, which includes leading Chinese technology and chip companies, had fallen 40% since July by October 26, erasing about $480 billion in value. It still traded at about 100 times past earnings, according to the report. This points to sharp differences in investor expectations, not proof that the underlying AI opportunity is the same across markets.

Six Measures Behind the Snapshot
The source frames its review around six figures: SK hynix’s record quarter; the role of Micron and Nvidia in U.S. earnings estimates; planned capital spending by four large technology companies; expected free-cash-flow pressure at Alphabet and Amazon; U.S. shipments and orders for capital goods; and the decline in China’s STAR50 index. Taken together, these indicators cover supplier profits, market concentration, investment, cash flow and broader demand rather than relying on a single measure of AI adoption.
SK hynix makes high-bandwidth memory used alongside AI processors. The company said long-term agreements with 14 major customers cover more than half of its capacity for 2027 and 2028, and it forecast that demand would exceed supply through 2030. That outlook is the company’s forecast, not a confirmed future outcome. The company also said it planned about 100 trillion won in dividends and buybacks for 2026; a portion of its buyback is allocated to employee compensation, according to the source.
The source was published as a preview before quarterly results from Microsoft and Alphabet on October 28 and Amazon on October 29. It said a dated update would follow once those results were released, but the material provided here contains no such update. The reported figures and expectations therefore describe the situation before those companies’ results were available.
“Demand [is expected] to exceed supply “through 2030.””
— SK hynix
The Payback Remains Unproven
At publication, the key quarterly results from Microsoft, Alphabet and Amazon had not been released, so their latest capital-spending guidance, cloud growth and free cash flow were still unknown. The source said analysts expected negative third-quarter free cash flow at Alphabet and Amazon, but those were expectations rather than reported results.
Other measures also have limits. S&P 500 growth figures were estimates ahead of company reports, and the source noted that one-time charges in the year-earlier period affected comparisons for some companies. SK hynix’s demand outlook is management’s projection, while the company’s reported results were preliminary and unaudited. The available material does not establish how quickly AI revenue will grow relative to infrastructure costs, or whether current spending levels will deliver returns.
The China index decline records a market move but does not, by itself, explain the causes or predict what happens next. The source also does not provide the promised post-results update, leaving the eventual reported figures and management comments outside this account.
Results Will Test Spending Plans
The next scheduled evidence was quarterly reporting from Microsoft and Alphabet on October 28, followed by Amazon on October 29. The source said readers should watch four areas: capital-spending guidance, cloud growth in relation to that spending, free cash flow and funding, and management statements about capacity. Those disclosures could show whether demand is keeping pace with investment, but one quarter alone would not settle the longer-term question of returns.
Investors will also be able to compare new company results with SK hynix’s reported demand and capacity picture and with the market’s earnings estimates. Any assessment should distinguish actual results from forecasts and should account for changes in guidance. The source material provided no subsequent update, so the outcomes of those scheduled reports are not stated here.
Key Questions
What is the main development in this AI boom review?
The October 28 review brought together six indicators ahead of major U.S. technology-company earnings. It paired SK hynix’s record operating profit with concerns about concentrated earnings growth, high spending and uncertain cash-flow returns.
What did SK hynix report for the third quarter?
SK hynix reported preliminary, unaudited revenue of 104.6 trillion won and operating profit of 83.3 trillion won. Operating profit rose 632% year over year, while net profit fell 58% from the prior quarter to 39.8 trillion won.
Why are Micron and Nvidia important to the earnings figures?
FactSet’s October 19 estimate showed that removing Micron and Nvidia lowered expected S&P 500 third-quarter earnings growth from 29.0% to 20.0%. These were estimates before several companies had reported, not final earnings results.
How much were four major technology companies planning to spend?
The source calculated that Alphabet, Amazon, Microsoft and Meta planned about $725 billion to $745 billion in combined 2026 capital spending, based on their guidance. The range is the source’s sum of company plans, not a single company forecast.
What information was still pending?
Microsoft and Alphabet were due to report on October 28 and Amazon on October 29. Their results, updated spending plans, cloud growth and cash-flow figures were not included in the source material, so the investment payoff remained unresolved.
