TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, 7.3 times its year-earlier result, highlighting the strong earnings of AI chip suppliers. The broader payoff remains uncertain: AI investment is concentrated among a few companies, capital spending is rising, and Microsoft, Alphabet and Amazon have yet to report.
SK hynix reported 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 Wednesday and Amazon on Thursday. The figures show how strongly demand for AI-related memory can lift suppliers, but the cloud companies’ reports will help investors judge whether their large AI infrastructure outlays are producing returns.
SK hynix, a major maker of high-bandwidth memory used alongside AI processors, said revenue reached 104.6 trillion won, up 328% year over year and its first quarter above 100 trillion won. Its reported operating margin was 80%. The results are preliminary and unaudited. Net profit was 39.8 trillion won, down 58% from the previous quarter, which the source attributes to non-operating items; operating and net profit therefore point in different directions.
The company said long-term agreements with 14 major customers cover more than half of its 2027 and 2028 capacity. SK hynix expects demand to exceed supply through 2030, but that is the company’s forecast, not an established outcome. It also announced a 14 trillion won dividend and a 20 trillion won buyback for the quarter. Its planned shareholder returns for 2026 total about 100 trillion won, according to the company. The source notes that half of the buyback is for employee compensation and is not counted by the company as a shareholder return.
Broader US earnings estimates also point to a strong but concentrated quarter. FactSet put blended third-quarter S&P 500 earnings growth at 29.5% as of October 23. In an October 19 analysis, FactSet estimated that removing Micron and Nvidia would lower the index’s growth rate from 29.0% to 20.0%. Those figures are estimates, and some major contributors had not reported. Separately, the four biggest US technology companies—Alphabet, Amazon, Microsoft and Meta—are expected to spend about $725 billion to $745 billion in 2026, based on the source author’s sum of their guidance.

AI Profits Meet the Payback Test
The results present two different parts of the AI investment cycle. Chip and memory suppliers are already reporting large profits, while cloud companies are committing substantial sums to data centers, processors and related infrastructure. Their earnings can show whether demand for AI services is translating into business growth, but a single quarter cannot establish that current spending will earn an adequate return over time.
The concentration of estimated earnings growth matters to readers because a strong index-wide figure may depend heavily on a small number of companies. FactSet’s calculation still leaves estimated S&P 500 growth at 20% after excluding Micron and Nvidia, but that is notably below its 29% overall estimate. Investors will also be watching capital spending, cloud growth and free cash flow together: rapid revenue growth alone does not show whether infrastructure costs are being covered.
The figures offer a mixed economic signal. US shipments of core capital goods rose 1.2% in September, while orders for computers and related products were up 20.3% this year, according to data cited from the Census Bureau. Those measures suggest AI-related investment is reaching parts of the wider economy, but they do not by themselves establish how profitable the spending will be.

Suppliers Surge as Markets Diverge
The October 28 report arrived amid sharply different market readings of AI and semiconductor prospects. SK hynix shares rose about 8% to 10% during the Seoul session, according to the source material, which cites CNBC. In China, the STAR50 index, which includes technology and chip companies, had fallen about 40% since July and lost roughly $480 billion in value, Reuters reported on October 26. The source says the index still traded at around 100 times past earnings. These market moves reflect different expectations and are not, on their own, proof that AI is either a boom or a bubble.
SK hynix’s own actions also include a cautionary note: its CEO said the company 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, according to the source’s account of the call. The company’s strong current results and the pause on that financing review can coexist; one reports present operating performance, while the other concerns a potential transaction amid uncertain market conditions.
The immediate focus is the earnings calendar. Microsoft and Alphabet are due to report later on October 28, followed by Amazon on October 29. Their disclosures can add detail on cloud demand, spending plans and cash generation, but results and management forecasts will not settle the long-term question of AI investment returns.
“The company expects demand to exceed supply through 2030.”
— SK hynix
Returns and Demand Still Unsettled
The most important unknown is whether spending on AI infrastructure will produce enough lasting revenue and cash flow to justify its cost. The source says analysts expected Alphabet and Amazon to report negative free cash flow again for the third quarter, but those results were still pending when the article was prepared. The outlook may change as companies release results and update guidance.
Several headline figures also need careful qualification. SK hynix’s third-quarter results are preliminary and unaudited; its expectation of supply shortages through 2030 is a forecast. S&P 500 earnings-growth figures are estimates, with several large companies yet to report. The source material does not provide the subsequent Big Tech results, so it cannot confirm whether cloud growth accelerated, capital-spending plans changed, or free cash flow improved.
It is also unclear how durable current memory pricing and demand will be, how much planned capacity will be used, and whether the gains will spread beyond a small group of suppliers and technology companies. The comparison with China’s falling technology index describes a market reversal, but does not establish that the same outcome will occur in US markets.
Earnings Reports Set the Next Checkpoint
Investors will next see Microsoft and Alphabet’s quarterly results on Wednesday, October 28, followed by Amazon’s on Thursday, October 29. The key disclosures are their capital-spending guidance, cloud growth, free cash flow and comments on capacity. Those figures can clarify whether infrastructure investment is rising alongside demand and whether the companies are generating cash after spending.
Management forecasts will be relevant, but they should be read as guidance rather than proof of future results. A fuller assessment will require later quarters showing whether AI-related revenue continues to grow, spending plans turn into productive capacity, and cash generation keeps pace. The SK hynix figures establish a strong quarter for one major supplier; the pending reports will add evidence about the customers funding much of the buildout.
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 its year-earlier figure, and the company reported an 80% operating margin.
Why are Microsoft, Alphabet and Amazon’s results important?
They are major cloud companies spending heavily on AI infrastructure. Their results and guidance will give investors more information about cloud growth, capital spending and free cash flow, though one reporting period cannot establish long-term returns.
Is the S&P 500 earnings boom broad-based?
Not fully, according to the cited FactSet estimate. FactSet estimated 29.0% growth, falling to 20.0% when Micron and Nvidia are excluded. The figures are estimates, and several companies had not reported at the time.
Did SK hynix confirm a memory shortage through 2030?
No. SK hynix said it expects demand to exceed supply through 2030. That is the company’s forecast, not confirmation that a shortage will last that long.
What remains unknown about AI spending?
It is not yet clear whether AI-related revenue and cash generation will be sufficient to justify the planned infrastructure costs over time. The pending earnings reports may add evidence, but the long-term payback remains unsettled.
