TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, up 7.3 times from a year earlier, highlighting the strength of demand for AI-related memory. But earnings growth is concentrated, major technology companies are committing hundreds of billions of dollars to capital spending, and the payoff from AI investment remains uncertain ahead of results from Microsoft, Alphabet and Amazon.
South Korean memory maker SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won on October 28, up 7.3 times from a year earlier, as investors awaited results from Microsoft and Alphabet later that day and Amazon on Thursday. The contrast captures the question facing investors: AI-related chip demand is producing large profits, but the returns on the much larger data-center investments by technology companies have yet to be established.
SK hynix said quarterly revenue reached 104.6 trillion won, a 328% increase from a year earlier and its first quarter above 100 trillion won. 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 figures are preliminary and unaudited.
The company said long-term agreements with 14 major customers cover more than half of its 2027 and 2028 production capacity. It expects demand to exceed supply through 2030, a forecast rather than a confirmed outcome. SK hynix also announced a 14 trillion won dividend and a 20 trillion won share buyback for the quarter. Its planned 2026 dividends and buybacks total about 100 trillion won; the company does not count half of the buyback, which is for employee compensation, as a shareholder return.
The broader earnings picture is less evenly distributed. FactSet estimated on October 23 that S&P 500 third-quarter earnings growth would be 29.5%. In an October 19 analysis, FactSet said removing Micron and Nvidia would lower the index’s expected growth from 29.0% to 20.0%. Those figures are estimates, and several major companies had not reported at the time. They show the importance of a small number of companies to the forecast, not the final reported result.

AI Profits and Investment Payback
The figures point to two different parts of the AI economy. Chip and memory suppliers are already reporting strong sales and profits, while cloud providers are spending heavily on data centers, processors and related infrastructure. The pending results matter because they can show whether cloud revenue is growing alongside capital spending, and whether that spending is beginning to generate cash rather than relying on expectations of future demand.
For investors, concentration adds another risk to the headline growth figures. If a few chip companies account for a large share of forecast earnings gains, their results and outlook can disproportionately affect the perceived health of the wider market. That does not make the other companies’ growth figures irrelevant: FactSet’s calculation still puts S&P 500 growth at 20% after excluding Micron and Nvidia. But the gap between the headline and adjusted estimate is a reminder to look at who is producing the growth, not only the index total.
Capital spending also has effects beyond company earnings. US Census Bureau data showed September shipments of core capital goods rose 1.2%, while orders for computers and related products were up 20.3% this year, through the period covered by the source. These figures offer evidence of investment reaching manufacturers, but do not establish how much spending is specifically for AI or whether it will earn an adequate return.

A Mixed Market Picture
The October 28 report arrived against sharply different market signals. SK hynix shares rose during the Seoul session, according to CNBC. Meanwhile, Reuters reported on October 26 that China’s STAR50 index, which includes AI and chip companies, had fallen 40% in under four months, erasing about $480 billion in market value. Reuters said the index still traded at around 100 times past earnings. That valuation figure uses historical earnings and does not predict future performance.
Spending plans give the upcoming company reports a wider frame. A calculation based on company guidance puts combined 2026 capital expenditure by Alphabet, Amazon, Microsoft and Meta at roughly $725 billion to $745 billion. Analysts expected Alphabet and Amazon to report negative free cash flow again for the third quarter, according to the source material. Those expectations are not company results; the reports will provide a fresh test of spending, cash generation and demand.
There was also a cautionary signal within SK hynix’s own update. CNBC reported that the company’s chief executive said it had halted a review of a possible pre-IPO funding round or listing for its US unit Solidigm, citing market volatility and a correction in semiconductor stocks. The decision does not negate the quarter’s reported results, but it shows that strong current demand and concerns about market conditions can coexist.
“Demand [is expected] to exceed supply through 2030.”

The Returns Still Need Proof
The main unknown is whether AI-related revenue will ultimately justify the scale and pace of planned investment. The source material describes AI revenue at cloud companies as growing, but does not provide a common, comparable measure of AI revenue or a definitive estimate of returns on data-center spending. Capital expenditure plans are not realized returns, and one quarter of results cannot settle the longer-term question.
Several of the figures available before the reports are forecasts, not final results. The FactSet earnings-growth estimates could change as companies report, and analyst expectations for negative free cash flow at Alphabet and Amazon remain unconfirmed until the companies publish their accounts. SK hynix’s demand outlook through 2030 is also a corporate projection. The source material provides no post-report results or update, so the eventual figures and management explanations are not yet available here.
Company Results Set the Next Test
Microsoft and Alphabet are scheduled to release quarterly results on October 28, followed by Amazon on October 29. Investors will be watching capital-spending guidance, cloud growth, free cash flow and capacity plans—including whether management sees enough demand to support further investment. Reported revenue and cash figures will be confirmed in the releases; explanations of future demand and spending will remain company outlooks.
The next comparison is whether spending growth is matched by stronger cloud business and cash generation, rather than by investment commitments alone. Results could also clarify whether the planned outlays are changing and how companies describe constraints on data-center capacity. Until those reports are available, the evidence supports a strong but concentrated supplier boom, while the overall payback from AI investment remains unsettled.
Key Questions
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. Operating profit was 7.3 times the figure a year earlier, and operating margin was 80%.
Why do Microsoft, Alphabet and Amazon’s results matter?
The companies are among the major planned spenders on AI infrastructure. Their results can show how cloud growth, capital spending and free cash flow are moving together, though the reports alone will not prove the long-term return on investment.
Are the S&P 500 earnings-growth figures final?
No. FactSet’s figures are blended estimates for the quarter. As of the dates cited, several companies had not reported, so the final growth rate could differ.
Does SK hynix’s forecast mean memory shortages will last through 2030?
No. SK hynix said it expects demand to exceed supply through 2030, but that is the company’s forecast. Future supply, customer demand and market conditions could change.
