TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, 7.3 times its year-earlier result, while Microsoft and Alphabet were due to report on October 28 and Amazon on October 29. Six figures in the source material point to strong chip profits and rising investment, but also concentrated earnings growth and an unresolved question: whether AI revenue will cover the cloud giants’ spending.
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 prepared for quarterly results from Microsoft and Alphabet that evening and Amazon on Thursday. The contrast captures the central question before Big Tech reports: AI infrastructure is generating striking profits for some suppliers, but the returns on cloud companies’ much larger investments remain uncertain.
The six figures in the source material show different parts of the AI investment cycle. SK hynix reported 104.6 trillion won in revenue, up 328% year over year, and an 80% operating margin. Its net profit, however, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items. The results were preliminary and unaudited.
Two figures track the concentration of US earnings growth: FactSet’s October 19 estimate said removing Micron and Nvidia would reduce expected S&P 500 third-quarter earnings growth from 29% to 20%. A separate FactSet blended estimate put growth at 29.5% as of October 23. These are estimates, not final reported results, and several major companies had yet to report.
Another pair concerns investment and the broader economy. Alphabet, Amazon, Microsoft and Meta plan a combined roughly $725 billion to $745 billion in 2026 capital spending, a total calculated from their guidance in the source. US September shipments of core capital goods rose 1.2%, while orders for computers and related products were up 20.3% for the year, according to the Census Bureau. The final figure looks at risk: analysts expected Alphabet and Amazon to post negative free cash flow again in the third quarter, according to the source.

AI Profits Meet the Payback Test
The results matter because they can show whether AI investment is turning into durable earnings or mainly expanding the cost base. Chip and memory suppliers are already benefiting from demand for data-center equipment, with SK hynix’s results offering a striking example. For cloud companies, however, the near-term test is whether revenue growth and cash generation keep pace with the cost of building capacity.
The earnings picture is also concentrated in a small number of companies. FactSet’s calculation still showed 20% expected index growth after excluding Micron and Nvidia, so the wider market was not projected to contract. But the gap between 29% and 20% indicates how much those two companies influence the headline estimate. Readers should treat both figures as forecasts until reporting is complete.
Capital spending can support future services and infrastructure, but spending plans alone do not establish that the investment will earn an adequate return. Free cash flow, cloud growth and capacity plans can help investors judge the pace of spending against current business performance. The supplied material does not establish whether AI revenue will ultimately cover the investments.

From Memory Chips to Cloud Spending
AI systems rely on large data centers, which require processors, high-bandwidth memory, networking equipment and power. SK hynix makes high-bandwidth memory used alongside AI processors. Its demand and earnings are therefore one indicator of the infrastructure buildout, though one supplier’s results cannot establish how profitable the whole industry is.
The source also describes a sharp split in markets: SK hynix shares rose during the Seoul session after its results, while China’s STAR50 index, which includes AI and chip companies, had fallen about 40% since July. Reuters reported the decline on October 26 and said it had erased about $480 billion in value; the index was still trading at around 100 times past earnings. These figures are a separate market signal, not a direct measure of US AI company earnings.
SK hynix said long-term agreements with 14 major customers cover more than half of its planned 2027 and 2028 capacity. The company forecast demand would exceed supply through 2030. That long-range outlook is the company’s forecast, not independently confirmed future demand. The source also reported that the company paused a review of funding or a possible listing for its US unit Solidigm, citing market volatility and a correction in semiconductor stocks.
“The company expects demand to exceed supply “through 2030.””

The Return on AI Spending
The supplied material is an earnings preview dated October 28, written before the scheduled results from Microsoft, Alphabet and Amazon. It does not include those companies’ reported results, so their actual quarterly revenue, capital spending and free cash flow remain unknown here. The source says analysts expected Alphabet and Amazon to report negative free cash flow again, but that expectation must not be confused with reported results.
It is also unclear how quickly AI services will generate revenue that offsets data-center investment, how much planned capital spending will change, and whether current demand for memory and chips will persist. SK hynix’s future-demand forecast and customer agreements provide company-specific indications, not proof of industry-wide returns. The source’s figures do not establish how much spending is directly attributable to AI or what portion of future revenue it will generate.
Results and Guidance to Watch
Microsoft and Alphabet were scheduled to report on the evening of October 28, followed by Amazon on October 29. The source identifies capital-spending guidance, cloud growth, free cash flow and capacity as the measures to watch. Comparing those figures with the companies’ plans and the prior quarter can help show whether spending is accelerating and whether cloud businesses are expanding alongside it.
The source says it would add a short, dated update after the results, but no update was provided in the supplied text. Until those figures and management commentary are available, the earnings picture remains a preview: supplier profits are documented, while the cloud investment payoff is still an open question.
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 year-earlier figure, and the operating margin was 80%.
Had Microsoft, Alphabet and Amazon reported when this preview was written?
No. The preview was dated October 28, 2026, before Microsoft and Alphabet were due to report that evening and Amazon on October 29. The supplied material does not include their results.
How much did Micron and Nvidia affect the earnings-growth estimate?
FactSet’s October 19 calculation said removing the two companies lowered expected S&P 500 third-quarter earnings growth from 29% to 20%. Those were estimates, not final reported growth figures.
What is the main unresolved issue for the AI boom?
The key uncertainty is whether cloud companies’ AI-related revenue and cash generation will grow enough to justify their infrastructure spending. The preview does not establish the eventual return on that investment.
