TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, while Microsoft and Alphabet are due to report on October 28 and Amazon on October 29. The results will help investors compare AI-related spending with cloud growth, cash flow and signs of demand—but the supplied preview does not include the companies’ earnings.
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won on October 28, while Microsoft and Alphabet were scheduled to report quarterly results that evening and Amazon on Thursday, October 29. A preview published by ThorstenMeyerAI.com identifies six indicators—including AI infrastructure spending, cloud growth and free cash flow—that investors can use to judge whether record chip-sector profits are being matched by returns from the companies building AI services.
SK hynix, a supplier of high-bandwidth memory used alongside AI processors, said third-quarter revenue reached 104.6 trillion won, up 328% from a year earlier. Its operating profit rose to 83.3 trillion won from 11.4 trillion won, producing an 80% operating margin, according to the company’s preliminary, unaudited release. Net profit was 39.8 trillion won, down 58% from the previous quarter, which the preview attributed to non-operating items.
The preview’s six checks are the scale of chip suppliers’ profits; the concentration of forecast US earnings growth; planned capital spending; cloud growth relative to that spending; free cash flow and how investment is funded; and what executives say about capacity. FactSet’s blended estimate put S&P 500 third-quarter earnings growth at 29.5% as of October 23. In a separate calculation dated October 19, FactSet said removing Micron and Nvidia would lower the growth estimate from 29.0% to 20.0%.
The four largest US technology companies—Alphabet, Amazon, Microsoft and Meta—were projected in the preview to spend a combined roughly $725 billion to $745 billion in 2026, based on the author’s sum of company guidance. The author also said analysts expected Alphabet and Amazon to report negative free cash flow again for the third quarter. Those expectations are not the companies’ reported results; the preview was written before the earnings announcements.

Testing AI Spending Against Returns
The central question is whether the profits earned by suppliers of memory and processors will be followed by durable returns for companies investing heavily in data centers and AI services. SK hynix’s reported results show strong current earnings at one key supplier, but they do not by themselves establish how quickly cloud providers can turn their spending into revenue or cash.
Concentration is another risk for readers tracking the wider market. FactSet’s estimate suggests Micron and Nvidia account for a substantial part of forecast S&P 500 earnings growth; removing them still leaves projected growth of 20.0%, but that is below the 29.0% figure in the cited comparison. These are estimates, not final results, and a few companies’ performance can shift the overall picture.
The spending scale also matters beyond technology stocks. The preview cited 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. These indicators suggest investment is reaching parts of the broader economy, though they do not isolate AI spending or prove that the investment will earn a sufficient return.

From Chip Profits to Cloud Spending
The comparison in the preview is between businesses selling the equipment needed for AI infrastructure and the cloud companies buying and operating it. High-bandwidth memory is a component used in AI data centers; demand for it has helped lift SK hynix’s reported revenue and operating profit. The company said long-term agreements with 14 major customers cover more than half of its 2027 and 2028 capacity.
SK hynix forecast that demand would exceed supply “through 2030,” according to its release. That is the company’s outlook, not an independently confirmed outcome. It also announced a plan to return about 100 trillion won to shareholders in 2026, including a 14 trillion won dividend and a 20 trillion won buyback approved for the quarter. The preview notes that half of the buyback relates to employee compensation and is not counted by the company as a shareholder return.
The preview contrasts those supplier results with signs of market volatility. It reported that China’s STAR50 index had fallen 40% since July, citing Reuters, while still trading at around 100 times past earnings. That movement offers a separate example of how sharply AI- and chip-linked valuations can change; it does not establish that US technology shares will follow the same path.
“Demand to exceed supply “through 2030.””

What Earnings Have Yet to Show
The preview was published before the scheduled results from Microsoft, Alphabet and Amazon. It does not provide their reported revenue, cloud growth, capital-spending updates or free cash flow, so those figures cannot yet be treated as confirmed here. It is also not clear from the supplied material whether the companies will give comparable detail on AI-related revenue or capacity constraints.
Several market figures are forecasts or interpretations rather than settled outcomes. The earnings-growth estimates depend on companies that had not yet reported, and the cited growth calculation can change as results arrive. SK hynix’s demand outlook through 2030 is a corporate forecast; the reported quarterly figures were preliminary and unaudited. The preview also says its author planned to add a dated update after the Big Tech results, but no such update is included in the supplied source material.
Results Will Fill in the Scorecard
Investors will be able to compare the companies’ reported results and guidance with the six checks once the scheduled earnings are released: spending plans, cloud growth, free cash flow and funding, alongside capacity commentary and the supplier profit picture. Microsoft and Alphabet were due to report October 28, followed by Amazon on October 29. The next useful comparison is whether their disclosures show AI-related demand growing alongside—or faster than—the cost of expanding infrastructure.
Those reports will not settle the longer-term return question on their own. They can update near-term evidence on growth, cash generation and investment, while future results will be needed to show whether spending supports sustained profits. The source preview provides no post-earnings figures or company commentary, so the outcome remains open.
