TL;DR
SK hynix reported record third-quarter operating profit on October 28, while Microsoft and Alphabet were due to report that evening and Amazon on Thursday. The results will test whether soaring AI infrastructure spending is being matched by cloud growth and cash generation, amid concentrated earnings gains and sharp losses in China’s AI and chip stocks.
SK hynix reported record third-quarter operating profit on Wednesday, October 28, while Microsoft and Alphabet were set to report results that evening and Amazon on Thursday. The contrast frames a key test for the AI boom: whether chipmakers’ strong profits and technology companies’ rising infrastructure spending are being matched by cloud growth and cash generation.
SK hynix said it earned 83.3 trillion won in operating profit, 7.3 times its result a year earlier, on revenue of 104.6 trillion won. Its reported operating margin was 80%. The release was preliminary and unaudited. Net profit was 39.8 trillion won, down 58% from the previous quarter, which the source attributes to non-operating items. The company also said long-term agreements with 14 major customers cover more than half of its 2027 and 2028 capacity.
The company expects demand to exceed supply through 2030, but that is SK hynix’s forecast, not an established outcome. It plans about 100 trillion won in dividends and share buybacks in 2026. The board approved a 14 trillion won dividend and a 20 trillion won buyback for the quarter; the source notes that half of the buyback is for employee compensation and is not counted by the company as a shareholder return.
The other measures in the preview are capital-spending guidance, cloud growth relative to spending, free cash flow and funding, and management commentary on capacity, alongside the broader earnings picture. Alphabet, Amazon, Microsoft and Meta together plan roughly $725 billion to $745 billion in capital spending in 2026, according to the source’s sum of their guidance. Analysts expected Alphabet and Amazon to report negative free cash flow again for the third quarter. These figures are not yet the companies’ reported results.

Can AI Spending Pay Back?
The results matter because the boom’s visible gains and its costs are landing in different parts of the technology industry. Memory and chip suppliers are reporting exceptionally high profits, while cloud and platform companies are committing hundreds of billions of dollars to data centers and related infrastructure. Investors will be looking for evidence that customer demand and AI-related revenue can support those outlays.
The earnings growth picture is also concentrated. FactSet’s October 19 analysis said removing Micron and Nvidia would reduce the S&P 500’s expected third-quarter earnings growth from 29.0% to 20.0%. The 20.0% figure would still represent growth, but the comparison shows how much of the forecast depends on two companies. It is an estimate before several major results, not a final account of earnings.
There are signs of spending reaching beyond technology-company accounts. The US Census Bureau reported that core capital goods shipments rose 1.2% in September, while orders for computers and related products were up 20.3% this year. Those numbers show activity in equipment orders and shipments; they do not establish how profitable AI investments will be or how much of the demand is directly attributable to AI.

Two Markets, Diverging Signals
The October 28 preview describes a split between strong chip-sector results and market weakness in China. In Seoul, SK hynix shares rose during the trading session after its results, while China’s STAR50 index, which includes AI and chip companies, had fallen 40% since July, erasing about $480 billion, according to Reuters on October 26. The source says the index still traded at around 100 times past earnings. Those are different markets and measures, not a direct comparison of company performance.
SK hynix makes high-bandwidth memory used alongside AI processors in data centers. Its results provide evidence that demand for key hardware is generating substantial revenue and operating profit for a major supplier. They do not show whether customers’ spending on AI systems will earn an adequate return over time.
The US earnings figures also require care. FactSet’s blended estimate for S&P 500 third-quarter earnings growth was 29.5% as of October 23. The separate calculation cited in the preview, dated October 19, put growth at 29.0% and estimated it would be 20.0% without Micron and Nvidia. These are forecast-based calculations made on different dates. The source also says some companies among the largest expected contributors had one-time charges in the year-earlier quarter, which can affect comparisons.
“Demand to exceed supply through 2030.”

The Payback Is Still Unproven
The central uncertainty is whether AI-related revenue will eventually justify the scale and pace of infrastructure spending. The preview says AI revenue at cloud companies is growing, but the spending is not yet being covered by current cash flow. That is an interpretation of the available figures, and the companies’ results and explanations could change the picture.
Several important details were still pending when the preview was published: the technology companies’ actual quarterly results, updated capital-spending plans, cloud growth rates, free cash flow and comments about capacity. Analysts’ expectations of negative free cash flow at Alphabet and Amazon were forecasts, not reported outcomes. SK hynix’s long-term demand outlook is also a company projection, while its quarter’s release was preliminary and unaudited.
The Shanghai index’s losses and high past-earnings valuation describe market conditions but do not, by themselves, establish whether China’s AI sector is in a lasting downturn. It also remains unclear from the source how much of the US equipment demand and corporate earnings growth can be attributed specifically to AI rather than other business activity.
Big Tech Results Set the Test
Microsoft and Alphabet were scheduled to report on the evening of October 28, followed by Amazon on Thursday, October 29. The next key evidence will be the companies’ reported cloud growth and free cash flow, their updated capital-spending guidance, and any explanation of how quickly new capacity is being built and used.
The preview said it would be updated after the results, but the supplied material contains no post-report figures or dated update. Until those results are available, the six measures offer a way to distinguish hardware demand and planned investment from demonstrated returns. The next reporting milestone is the companies’ earnings releases and accompanying management commentary.
Key Questions
What is the main development in this report?
SK hynix reported record third-quarter operating profit before Microsoft, Alphabet and Amazon were due to report results. The preview uses those events to assess whether AI spending is translating into sustainable revenue and cash generation.
What does SK hynix’s quarter show?
The company reported 83.3 trillion won in operating profit, 7.3 times its year-earlier result, and an 80% operating margin. Its release was preliminary and unaudited; the result alone does not establish whether AI infrastructure spending will pay off for customers.
Why watch cloud growth and free cash flow?
Cloud growth can indicate demand for services tied to AI infrastructure, while free cash flow shows how much cash remains after operating costs and investment. The source said analysts expected Alphabet and Amazon to report negative free cash flow for the quarter, but those were expectations ahead of results.
How concentrated is expected S&P 500 earnings growth?
FactSet’s October 19 calculation estimated that removing Micron and Nvidia would lower expected third-quarter S&P 500 earnings growth from 29.0% to 20.0%. These were estimates before several companies had reported, not final results.
What is not yet known?
The supplied material does not include the later results from Microsoft, Alphabet or Amazon. Their actual capital spending, cloud growth, free cash flow and capacity plans—and the eventual returns on AI investment—remain unresolved in this preview.
