TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, while China’s STAR50 index has fallen 40% since July. The AI boom is generating substantial profits for chipmakers, but earnings are concentrated and major technology companies’ spending has yet to show clear cash-flow payback. Microsoft and Alphabet report Wednesday, followed by Amazon on Thursday.
Ahead of quarterly results from Microsoft and Alphabet on Wednesday and Amazon on Thursday, a six-number check of the AI boom points to a split picture: chipmaker SK hynix reported record preliminary third-quarter operating profit of 83.3 trillion won, while a leading Chinese AI and chip-stock index has dropped 40% since July. The figures show real profits and investment, but also concentrated earnings and unresolved questions about whether technology companies can earn back their spending.
SK hynix, a major supplier of high-bandwidth memory used alongside AI processors, said third-quarter revenue reached 104.6 trillion won, up 328% from a year earlier. Operating profit rose 632%, to 83.3 trillion won from 11.4 trillion won, giving the company an 80% operating margin. The release was preliminary and unaudited. Net profit, by contrast, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items.
The company said long-term agreements with 14 major customers cover more than half of its planned capacity for 2027 and 2028. Its expectation that demand will exceed supply through 2030 is a company forecast, not an established outcome. SK hynix also announced a 14 trillion won dividend and a 20 trillion won share buyback this quarter. The source report says the company plans roughly 100 trillion won in dividends and buybacks in 2026, though half of the buyback is for employee compensation and is not counted by the company as a shareholder return.
The other measures in the report look beyond chipmaker profits: how much the boom depends on two companies, how much the major cloud providers are spending, whether cloud growth covers that spending, how free cash flow and funding are changing, and what executives say about capacity. The report says Alphabet, Amazon, Microsoft and Meta plan a combined roughly $725 billion to $745 billion in 2026 capital spending, based on its sum of their guidance. It also cites analysts expecting Alphabet and Amazon to report negative free cash flow again for the third quarter.

Chip Profits Meet Big Tech Spending
The figures matter because they capture different stages of the AI investment cycle. Suppliers such as SK hynix sell the memory needed for data centers and are already reporting sharp revenue and profit growth. Cloud companies are financing the infrastructure, but large spending plans make cash flow and customer revenue key tests of whether the investment is paying for itself.
The earnings picture is also concentrated. FactSet estimated S&P 500 third-quarter earnings growth at 29.0% in an analysis dated October 19, but said growth would fall to 20.0% if Micron and Nvidia were excluded. That calculation is an estimate, and several large contributors had not yet reported. Even so, it shows why the index-wide growth figure may not describe the experience of the broader market.
Investment is reaching beyond company accounts. 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 Census Bureau figures cited in the report. Those indicators show activity in the wider economy, but they do not by themselves establish how profitable the resulting AI capacity will be.

A Boom With Uneven Signals
The report, published October 28, frames its numbers as a preview before results from major cloud and technology companies arrive. Its central distinction is between measured profits at chip suppliers and the still-open question of returns on the infrastructure investment. SK hynix’s quarter is a concrete report of past performance; the company’s demand outlook and the cloud providers’ future returns are forward-looking matters.
Market signals also differ by region. While SK hynix shares rose during the Seoul session, the source says China’s STAR50 index, which includes AI and chip companies, had fallen 40% since July and shed about $480 billion in value, citing Reuters on October 26. The index still traded at around 100 times past earnings, according to that report. Those figures describe a market drawdown and valuation at a particular time, not proof that the Chinese sector or the wider AI market will follow the same course.
FactSet’s earnings-growth estimate and its comparison excluding Micron and Nvidia are not final results. The source notes that some companies among the largest contributors, including Meta, EchoStar and Boeing, faced easier year-over-year comparisons because of charges in the prior-year quarter. The earnings picture may change as more companies report.
“Demand is expected to exceed supply through 2030.”
— SK hynix
Returns and Demand Remain Unsettled
The key question is whether AI-related revenue can grow enough to justify the cloud companies’ planned spending. The available preview figures do not settle that question: quarterly results were still pending, and the expectation of negative free cash flow at Alphabet and Amazon came from analysts, not reported company results.
It is also unclear how durable the current supply-demand balance will be. SK hynix’s agreements cover a substantial share of capacity in 2027 and 2028, but its prediction of shortages through 2030 remains a forecast. The report does not provide enough detail to determine how much of each cloud provider’s spending is dedicated specifically to AI, how quickly new capacity will be used, or what returns it will generate.
Finally, the index and earnings measures are snapshots. China’s 40% decline covers a period beginning in July, while US earnings-growth figures are estimates that may shift as more results arrive. Neither number alone establishes whether AI investment overall is a boom or a bubble.
Results Will Test Spending Plans
Microsoft and Alphabet are scheduled to report quarterly results Wednesday, October 28, followed by Amazon on Thursday, October 29. Investors and readers will be able to compare their reported cloud growth and cash flow with their capital-spending plans, and listen for management’s explanations of capacity, demand and funding.
The most useful updates will distinguish reported figures from guidance and analyst expectations. The source preview says it will add a dated update after the results are released; the figures and claims presented here are the information available before those reports. Until the companies publish their results, the scale of near-term AI returns remains unsettled.
Key Questions
What is the main development in this report?
The October 28 report sets out six measures for judging the AI boom before quarterly results from Microsoft, Alphabet and Amazon. It highlights SK hynix’s record preliminary operating profit alongside market declines and questions about spending returns.
How did SK hynix perform in the third quarter?
SK hynix reported preliminary, unaudited revenue of 104.6 trillion won and operating profit of 83.3 trillion won. Operating profit was 632% higher than a year earlier, while net profit fell 58% from the previous quarter to 39.8 trillion won.
Why does the report focus on Micron and Nvidia?
FactSet’s October 19 estimate showed that excluding Micron and Nvidia would reduce expected S&P 500 third-quarter earnings growth from 29.0% to 20.0%. The calculation highlights concentration; it is an estimate, not a final tally of reported earnings.
Have Big Tech companies shown that AI spending is paying off?
These preview figures do not establish that. The report says major technology companies have large spending plans and cites analysts expecting negative third-quarter free cash flow at Alphabet and Amazon. Their scheduled results may offer more evidence, but the long-term returns remain uncertain.
What happens next?
Microsoft and Alphabet are scheduled to release quarterly results Wednesday, October 28, and Amazon on Thursday, October 29. Their reported cloud growth, free cash flow, spending guidance and comments on capacity are the next figures to watch.
