TL;DR
SK hynix reported record third-quarter operating profit as demand for AI memory lifted its results, while US earnings growth remains concentrated in a few companies and major cloud firms are spending heavily. The figures point to strong demand for AI infrastructure, but they do not yet establish whether revenue will repay the investment. Microsoft and Alphabet report on October 28, followed by Amazon on October 29.
SK hynix reported 83.3 trillion won in third-quarter operating profit on October 28, about 7.3 times its year-earlier result, as investors awaited results from Microsoft and Alphabet and then Amazon. The figures show that demand for AI-related memory is generating substantial profits, but they do not settle whether Big Tech’s large infrastructure bills will earn an adequate return.
The six-number review published by ThorstenMeyerAI.com on October 28 puts the chip boom alongside the spending and market risks behind it. SK hynix’s preliminary, unaudited release reported 104.6 trillion won in revenue, up 328% from a year earlier, and an 80% operating margin. Net profit, however, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items. The different measures show why operating profit alone does not describe the whole financial picture.
The review also points to concentration in US corporate earnings. FactSet estimated third-quarter S&P 500 earnings growth at 29.5% as of October 23. In an earlier calculation dated October 19, FactSet analyst John Butters estimated that removing Micron and Nvidia would lower growth from 29.0% to 20.0%. Those figures are estimates, and several companies had yet to report; 20% growth without the two chipmakers would still be substantial.
Investment is the other central measure. Alphabet, Amazon, Microsoft and Meta together plan about $725 billion to $745 billion in 2026 capital spending, according to the article’s sum of company guidance. The author says analysts expect Alphabet and Amazon to report negative free cash flow again for the third quarter. The review also cites US Census Bureau data showing core capital-goods shipments rose 1.2% in September and orders for computers and related products were up 20.3% this year. Those economic indicators are consistent with rising investment, but do not show how much spending is specifically for AI.

Profits Rise as Payback Is Tested
The figures describe a boom with clear winners and unresolved financial questions. Memory and chip suppliers are already reporting strong results; cloud companies are committing large sums to data centers and related infrastructure. The key test for investors is whether cloud revenue and cash generation grow enough to support that spending over time. The current figures do not answer that on their own.
The concentration of earnings matters because headline growth can overstate how broadly companies are benefiting. FactSet’s calculation still shows strong growth after excluding Micron and Nvidia, but the gap between 29.0% and 20.0% illustrates how much those two companies influence the forecast. Meanwhile, high capital spending can support suppliers and equipment orders even before the spending produces returns for the companies making it.
China’s market provides a contrasting signal. Reuters reported that the STAR50 index, which includes Chinese AI and chip companies, had fallen 40% in under four months by October 26, erasing about $480 billion in market value. The index was still trading at around 100 times past earnings, according to the report. The decline shows investor expectations can reverse sharply; it does not, by itself, establish that AI demand or company revenues have collapsed.

Six Measures Behind the AI Trade
The article frames its numbers as a snapshot taken before major technology-company earnings, rather than a verdict on the industry. The first indicator is SK hynix’s results as a supplier of high-bandwidth memory, which sits alongside processors in AI data centers. The company said long-term agreements with 14 major customers cover more than half of its 2027 and 2028 capacity. Its expectation that demand will exceed supply through 2030 is a company forecast, not an independently established outcome.
Other measures track the breadth of earnings growth, capital expenditure, free cash flow, real-economy investment and the Chinese stock-market decline. The review notes that SK hynix plans about 100 trillion won in dividends and share buybacks for 2026, including a 14 trillion won dividend and a 20 trillion won buyback approved in the quarter. It also reports that the company halted a review of funding or a possible listing for its US unit Solidigm, with its chief executive citing volatility and a correction in semiconductor stocks. That decision is a reminder that even a company posting record operating results may still respond to market conditions.
The six indicators are not interchangeable: company guidance, analyst estimates, reported results and market prices measure different things. In particular, forecasts for spending or demand should not be treated as realized revenue, and market valuations do not directly measure the underlying pace of AI adoption.
“The company expects demand to exceed supply through 2030.”

What Earnings Cannot Yet Show
Results from Microsoft, Alphabet and Amazon had not been reported when the October 28 review was published. Their disclosures could change the picture on capital spending, cloud growth and free cash flow, but the source material provides no later results. It is also unclear how quickly current spending will translate into recurring AI revenue or whether demand will match the capacity being built.
The earnings-growth figures are forecasts rather than final results, and several major contributors had not reported. The source does not provide a complete breakdown of the four companies’ planned capital spending or isolate the share devoted to AI. Nor does the STAR50’s decline establish that every company in the index experienced the same business conditions. Those limits make the six measures useful signals, not a single definitive measure of whether the AI boom is a bubble.
Results Will Test Spending Plans
Microsoft and Alphabet were scheduled to report quarterly results on October 28, with Amazon due on October 29. The review identifies four items to watch in those disclosures: capital-spending guidance, cloud growth relative to spending, free cash flow and management’s comments on capacity. Together, they may clarify whether investment is rising alongside customer demand and whether cash generation is keeping pace.
SK hynix’s reported results are preliminary and unaudited, so its final figures may also be relevant. Any update to the analysis should distinguish reported results from management forecasts and analyst estimates. The source article says it planned a short dated update after Big Tech results, but the material provided here does not include that follow-up.
Key Questions
What is the main takeaway from the six numbers?
The review finds real profits at AI infrastructure suppliers, but also concentrated US earnings growth and large planned investments whose eventual returns remain uncertain.
What did SK hynix report?
SK hynix reported preliminary, unaudited third-quarter revenue of 104.6 trillion won and operating profit of 83.3 trillion won, up 328% and 632%, respectively, from a year earlier. Its reported operating margin was 80%.
How concentrated is the forecast US earnings growth?
FactSet’s October 19 calculation estimated that removing Micron and Nvidia would reduce S&P 500 third-quarter earnings growth from 29.0% to 20.0%. The estimate was not a final result for all companies.
Do the figures prove the AI boom is a bubble?
No. The numbers show strong supplier profits, major investment and a sharp drop in a Chinese AI and chip index. They do not establish whether future AI revenues will repay the spending or settle the broader bubble question.
Which results were due next?
Microsoft and Alphabet were scheduled to report on October 28, 2026, followed by Amazon on October 29. The review said readers should watch spending guidance, cloud growth, free cash flow and capacity comments.
