TL;DR
SK hynix reported third-quarter operating profit of 83.3 trillion won, 7.3 times its year-earlier result, while major U.S. technology companies are due to report quarterly earnings. The data point to strong chip demand but also concentrated earnings growth, heavy planned spending and open questions about whether AI revenue will cover investment.
South Korean memory maker SK hynix reported third-quarter operating profit of 83.3 trillion won on Wednesday, 7.3 times its result a year earlier, as investors awaited quarterly results from Microsoft and Alphabet later that day and Amazon on Thursday. The results will help test whether surging demand for AI chips is being matched by sustainable growth in cloud revenue and cash generation.
SK hynix said revenue reached 104.6 trillion won, up 328% from the same quarter last year, while operating margin was 80%. Its net profit, however, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items. The company’s October 28 release was preliminary and unaudited. Its shares rose during the Seoul session, CNBC reported.
The company said long-term agreements with 14 major customers cover more than half of its planned 2027 and 2028 capacity. SK hynix expects demand to exceed supply through 2030, but that is the company’s forecast, not a confirmed outcome. It also announced a 14 trillion won dividend and a 20 trillion won buyback for the quarter; the source material says half the buyback is linked to employee compensation and is not counted by the company as a shareholder return.
The broader figures show a boom with uneven foundations. FactSet estimated on October 23 that S&P 500 third-quarter earnings would grow 29.5% on a blended basis. A FactSet calculation cited in the source material found that excluding Micron and Nvidia would reduce expected growth from 29.0% to 20.0%. Meanwhile, Alphabet, Amazon, Microsoft and Meta have indicated combined 2026 capital spending of roughly $725 billion to $745 billion, based on the source author’s sum of their guidance.

Testing AI Spending Against Returns
The reports matter because the largest technology companies are committing hundreds of billions of dollars to data centers, chips and related infrastructure. Investors will be looking for evidence that revenue from cloud and AI services is growing quickly enough to support that spending, and whether companies can fund it without weakening their cash positions.
The figures point in different directions. Chip and memory suppliers are recording exceptional profits, while the spending companies still face questions about payback. The source material says analysts expect Alphabet and Amazon to report negative free cash flow again for the third quarter; those are expectations, not reported results. A strong quarter for chipmakers does not by itself establish that every major infrastructure investment will earn an adequate return.
Concentration also matters. If a small number of companies account for a large share of projected index growth, changes in their results can have an outsized effect on the overall picture. Even without Micron and Nvidia, the cited estimate of 20% growth would still be substantial, but it is below the headline figure.

Six Figures Behind the Boom
The first number is SK hynix’s operating profit: 83.3 trillion won, compared with 11.4 trillion won a year earlier. Its 80% operating margin shows the extraordinary profitability of the current memory-market conditions, while the quarter-on-quarter decline in net profit shows why operating profit is not the only measure to watch.
The second is the earnings-growth estimate. FactSet’s October 23 blended estimate was 29.5% for S&P 500 companies. A separate October 19 calculation in the source material put growth at 29.0% before removing Micron and Nvidia, and 20.0% after. These are estimates made before all companies had reported, not final earnings results.
The third is planned capital spending: roughly $725 billion to $745 billion across Alphabet, Amazon, Microsoft and Meta in 2026, as summed from company guidance by the source author. The fourth is free cash flow, particularly whether reported cash generation holds up alongside that investment. The fifth is real-economy demand: U.S. shipments of core capital goods rose 1.2% in September, while orders for computers and related products were up 20.3% year to date, according to the Census Bureau figures cited in the source material.
The sixth is a warning about market reversals. Reuters reported on October 26 that China’s STAR50 index, which includes major AI and chip companies, had fallen 40% since July and erased about $480 billion in value. The index still traded at about 100 times past earnings. That decline does not establish that U.S. technology stocks will follow the same path, but it illustrates how quickly expectations and valuations can change.
“Demand will exceed supply through 2030.”

Payback and Earnings Still Unclear
The upcoming reports had not been released in the source material, so their actual revenue, profit, capital spending and free cash flow figures were not yet confirmed. It also remains unclear whether AI-related revenue will grow enough to cover the sector’s planned infrastructure spending over time. The estimates for index earnings growth may change as more companies report.
SK hynix’s forecast of demand exceeding supply through 2030 is the company’s view, and the figures supplied do not establish how long current pricing or margins will last. The source material also describes the STAR50 decline and high valuation but does not explain all causes of the sell-off. The comparison is a cautionary example, not proof that another market will follow the same course.
Cloud Results Set the Next Test
Microsoft and Alphabet are scheduled to report Wednesday evening, followed by Amazon on Thursday. The most useful details to compare are each company’s capital spending guidance, cloud growth, free cash flow and comments on capacity. Those disclosures will show whether investment plans are increasing, whether cloud demand is keeping pace, and how much cash remains after spending.
The source material describes the article as a preview dated October 28 and says a short update would be added after the results. Until those earnings are available, the central question remains open: the AI buildout has produced striking profits for some suppliers, but the reports will provide a clearer indication of whether the companies paying for the buildout are seeing returns to match.
Key Questions
What was SK hynix’s operating profit in the third quarter?
SK hynix reported 83.3 trillion won in preliminary, unaudited operating profit for the third quarter, up from 11.4 trillion won a year earlier.
Which major technology companies are reporting next?
Microsoft and Alphabet were scheduled to report Wednesday, October 28, 2026. Amazon was scheduled to report on Thursday.
Why are investors focused on capital spending and free cash flow?
The four companies named in the source material—Alphabet, Amazon, Microsoft and Meta—are expected to spend roughly $725 billion to $745 billion in 2026, based on the source author’s sum of their guidance. Free cash flow helps show how much cash companies generate after investment.
Does SK hynix’s result prove the AI boom will continue?
No. It confirms a very strong quarter for SK hynix, but it does not establish how long demand, margins or chip prices will remain at current levels. The company’s forecast of demand exceeding supply through 2030 remains a forecast.
What should readers watch in the upcoming earnings reports?
Compare capital spending guidance, cloud growth, free cash flow and capacity comments. Together, those figures can help show whether AI infrastructure investment is producing revenue and cash generation to support its cost.
