TL;DR
SK hynix reported record third-quarter operating profit on October 28, while a sharp fall in Chinese AI and chip stocks showed how quickly sentiment can reverse. Ahead of results from Microsoft, Alphabet and Amazon, six figures offer a way to separate current chip profits and economic demand from concentrated earnings, rising investment costs and uncertain payback.
SK hynix reported record third-quarter operating profit on October 28, while a Chinese index of AI and chip companies had fallen 40% since July. The contrast frames a timely test of the AI boom: whether chipmakers’ strong profits and rising demand can be matched by cloud companies’ revenue and cash returns, as Microsoft, Alphabet and Amazon prepare to report.
SK hynix, a supplier of high-bandwidth memory used alongside AI processors, reported revenue of 104.6 trillion won and operating profit of 83.3 trillion won for the third quarter. The company said revenue was up 328% from a year earlier and operating profit rose from 11.4 trillion won, about 7.3 times the prior-year figure. Its reported operating margin was 80%. The release was preliminary and unaudited.
The quarter was not uniformly stronger across every measure: net profit was 39.8 trillion won, down 58% from the previous quarter, which the company attributed to non-operating items. SK hynix said long-term agreements with 14 major customers cover more than half of its capacity for 2027 and 2028. Its expectation that demand will exceed supply through 2030 is a company forecast, not a confirmed outcome.
The broader figures point in different directions. FactSet estimated S&P 500 third-quarter earnings growth at 29.5% as of October 23; its October 19 analysis found that excluding Micron and Nvidia would reduce the cited growth measure from 29% to 20%. Meanwhile, Alphabet, Amazon, Microsoft and Meta planned a combined roughly $725 billion to $745 billion in 2026 capital spending, according to the source’s sum of company guidance. US Census Bureau data showed shipments of core capital goods rose 1.2% in September and orders for computers and related products were up 20.3% this year.

Profits, Spending and Payback
The figures matter because the AI investment cycle links companies with very different financial positions. Memory and chip suppliers are already reporting substantial profits, while cloud companies are committing hundreds of billions of dollars to infrastructure. That spending may support further demand for chips, servers and related equipment, but its scale also makes the eventual revenue and cash returns important to investors and businesses.
The earnings-growth estimate is strong, but its concentration changes how it should be read. If two chipmakers account for a large part of expected growth, the headline does not describe every company in the index. FactSet’s cited calculation still showed 20% growth after excluding Micron and Nvidia, so the data do not indicate that growth disappears; they do show that a small number of firms shape the overall result.
Cash flow offers another check on whether investment is being funded by operating performance or requires other financing. The source expected Alphabet and Amazon to report negative free cash flow again for the third quarter, but those results had not yet been released. The distinction between forecast and reported figures is central to judging whether AI demand is translating into durable returns.

Six Measures Behind the AI Trade
The source’s six-number framework combines company results, market estimates and economic indicators rather than treating one figure as proof of a boom or a bubble. SK hynix’s profit and margin measure current supplier strength; its net profit shows why operating profit alone does not tell the whole story. The company’s customer agreements indicate planned demand coverage, while its longer-term supply outlook remains a forecast.
US earnings concentration is a separate measure: FactSet’s estimates show how much expected index growth depends on Micron and Nvidia. The spending figure aggregates guidance from four large technology companies, so it is a planned investment total, not money already spent. The source also flags free cash flow and funding, and management commentary on capacity, as key information to watch in the upcoming results.
Finally, industrial data and China’s market decline provide contrasting signals. US shipments and orders suggest activity in capital goods and computers, but do not by themselves establish how much demand is specifically driven by AI. Reuters reported that China’s STAR50 index had lost 40% in under four months and erased about $480 billion by October 26; the source said it still traded at around 100 times past earnings. The index movement describes market pricing, not the operating results of every company it contains.
“Demand [is expected] to exceed supply “through 2030.””

What the Results Cannot Yet Show
At the time of the October 28 preview, Microsoft and Alphabet had not reported, and Amazon’s results were due the following day. Their actual capital spending, cloud growth, free cash flow and explanations of infrastructure capacity therefore remained unknown. The source’s expectation of negative third-quarter free cash flow for Alphabet and Amazon was an analyst forecast, not a reported result.
Some of the broader earnings figures were also estimates, and several major companies, including Nvidia, had yet to report. Comparisons can be affected by unusual charges in the year-ago period, the source noted for Meta, EchoStar and Boeing. The available figures do not establish how much AI revenue will ultimately be generated by the new spending, when that revenue may arrive, or whether current demand and valuations will hold.
The article described itself as a preview and said it would add a dated update after the technology companies’ results. No such post-results update or figures are included in the supplied material, so the companies’ eventual reported outcomes cannot be stated here.
The Big Tech Reports to Watch
The immediate next milestone is the quarterly reporting from Microsoft and Alphabet on October 28, followed by Amazon on October 29, according to the source. Investors will be able to compare reported cloud growth and free cash flow with the companies’ investment plans, and hear what executives say about capacity and demand.
Those disclosures can sharpen the comparison between current AI-related spending and business results, but a single quarter will not settle the longer-term question of payback. The source said it planned a short, dated update once the reports were out; that update is not part of the material provided. Until reported figures and further results are available, the most grounded conclusion is that chip profits are strong, expected earnings growth is concentrated, and the returns on major infrastructure spending remain to be tested.
Key Questions
What did SK hynix report?
SK hynix reported third-quarter revenue of 104.6 trillion won and operating profit of 83.3 trillion won. Its October 28 release was preliminary and unaudited; it also reported net profit of 39.8 trillion won, down 58% from the previous quarter.
Does the earnings data show that AI growth is broad-based?
Not fully. FactSet estimated S&P 500 earnings growth at 29.5% as of October 23. Its cited analysis said excluding Micron and Nvidia reduced a growth measure from 29% to 20%, indicating that the two companies account for a substantial share while projected growth remains positive without them.
How much were major technology companies planning to spend?
The source calculated that Alphabet, Amazon, Microsoft and Meta planned roughly $725 billion to $745 billion in capital spending during 2026, based on their guidance. This is a planned total, not a report of spending already completed.
What should readers look for in the upcoming results?
Key disclosures include capital spending guidance, cloud growth, free cash flow and funding, as well as management comments about capacity. These can help readers compare investment plans with reported business performance, though they cannot settle the long-term return question on their own.
