TL;DR
SK hynix reported record third-quarter operating profit on October 28, while US AI-related earnings growth and investment remain concentrated among a small group of companies. The figures suggest strong demand for AI hardware, but whether cloud companies can earn enough to cover their spending remains unresolved ahead of results from Microsoft, Alphabet and Amazon.
South Korean memory-chip maker SK hynix reported record third-quarter operating profit on October 28, while a sharp fall in Chinese AI and chip stocks and heavy planned investment by US technology companies offered a less certain view of the AI boom. The figures arrive just before Microsoft and Alphabet report quarterly results, followed by Amazon on Thursday, with investors looking for evidence that AI revenue can support the spending.
SK hynix said revenue reached 104.6 trillion won, up 328% from a year earlier, and operating profit was 83.3 trillion won, up 632% from 11.4 trillion won. Its operating margin was 80%. The company’s October 28 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 capacity for 2027 and 2028. SK hynix expects demand to exceed supply through 2030, but that is a company forecast, not a confirmed outcome. It also announced a 14 trillion won dividend and a 20 trillion won share buyback for the quarter. Its planned shareholder payouts for 2026 total about 100 trillion won, according to the source report.
The broader market indicators point in different directions. FactSet’s October 19 analysis said removing Micron and Nvidia from its calculation would reduce estimated S&P 500 third-quarter earnings growth from 29% to 20%. Separately, the source report estimates that Alphabet, Amazon, Microsoft and Meta plan about $725 billion to $745 billion in capital spending in 2026, based on their guidance. US core capital-goods shipments rose 1.2% in September, while orders for computers and related products were up 20.3% this year, according to the Census Bureau on October 27.

AI Profits Meet a Costly Buildout
The figures distinguish between companies selling the equipment needed for AI and the cloud platforms paying to build data centers. SK hynix’s results show that demand for high-bandwidth memory is generating substantial current profits for at least one supplier. But those results do not establish that cloud companies will earn a sufficient return on their own investments.
That gap matters because the planned spending is large and corporate earnings growth is concentrated. FactSet’s estimate still implies 20% S&P 500 growth without Micron and Nvidia, a strong rate in its own right, but the two companies materially lift the headline. Investors will be watching whether cloud revenue growth, cash flow and capacity plans support continued spending, rather than relying on equipment demand alone.
The contrast with China is another caution against treating AI-related markets as a single, uniformly rising trade. The source report says the STAR50 index, which tracks major Chinese technology and chip companies, had fallen about 40% since July and lost roughly $480 billion in value. It cited Reuters for the decline and said the index still traded at around 100 times past earnings. That valuation measure and market drop describe risk and sentiment; they do not by themselves prove that the sector is a bubble.

Six Measures Behind the Debate
The source report organizes the debate around six indicators: SK hynix’s profit and margin; the concentration of US earnings growth; planned capital expenditure; cloud growth compared with that investment; free cash flow and funding; and management commentary on capacity. Together they cover different stages of the AI business, from chip supply to the ability of customers to pay for infrastructure.
The measures have limits. SK hynix’s quarterly figures are preliminary, and its long-term demand outlook is a forecast. The earnings-growth figures are estimates while several major companies have yet to report. The capital-spending total is the source author’s sum of company guidance, not a single figure published by the four companies together. The report also says analysts expect Alphabet and Amazon to post negative free cash flow again for the third quarter; that expectation must be checked against the companies’ actual results.
On October 28, Microsoft and Alphabet were due to report that evening, with Amazon scheduled for October 29. The source material was written as a preview before those results, so it contains no confirmed figures from those reports. Meta is included in the 2026 spending estimate, but its results are not identified in the supplied material as part of this week’s reporting sequence.
“The company expects demand to exceed supply through 2030.”
— SK hynix
Returns and Demand Remain Unsettled
The key open question is whether AI-related revenue will generate enough cash to justify the scale of planned investment. The supplied material gives a spending estimate but does not provide confirmed results from Microsoft, Alphabet or Amazon for the quarter. It therefore cannot establish the latest cloud growth, free cash flow or management outlook against that spending.
Other limits also remain. The S&P 500 figures are estimates, and removing two companies is a calculation rather than a forecast of what the index will earn. SK hynix’s figures are preliminary and unaudited, while its expectation of demand through 2030 is a corporate projection. The source also reports a fall in the Chinese STAR50 index but does not establish how much of that decline reflects company fundamentals, valuation changes or broader market conditions.
SK hynix’s CEO also said the company had halted its 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 report’s account of the call. That decision offers evidence of caution, but the supplied material does not give further details about the process or its future.
Results Will Test Spending Plans
Microsoft and Alphabet’s scheduled October 28 reports, followed by Amazon’s October 29 results, are the next immediate milestones. Investors will be able to compare reported cloud growth and cash flow with management’s capital-spending guidance. Any revisions to spending plans, data-center capacity or expected AI demand will help clarify whether investment is accelerating, holding steady or being reassessed.
The source report identifies four areas to monitor: capital-spending guidance, cloud growth relative to spending, free cash flow and funding, and comments on capacity. Those disclosures can test the central question, but they may not settle it: spending and returns can emerge over different time horizons, while company forecasts remain subject to change. No post-results update is included in the supplied material.
Key Questions
What is the main development?
SK hynix reported a record third quarter, with operating profit of 83.3 trillion won, as investors prepared for results from Microsoft, Alphabet and Amazon that could shed light on the returns from AI infrastructure spending.
Does SK hynix’s result prove the AI boom is sustainable?
No. It shows strong reported results for one major memory supplier. The figures are preliminary and unaudited, and they do not establish whether cloud companies will earn enough from AI services to cover their investments.
How concentrated is the US earnings growth estimate?
FactSet’s October 19 calculation said that excluding Micron and Nvidia would lower estimated S&P 500 third-quarter earnings growth from 29.0% to 20.0%. The figures are estimates, not final results.
How much are major technology companies planning to spend?
The source report estimates Alphabet, Amazon, Microsoft and Meta together plan about $725 billion to $745 billion in capital spending for 2026, based on company guidance. This is the report author’s combined estimate, not a separately issued joint figure.
What should readers watch in the next results?
Look for reported cloud growth alongside capital-spending guidance, free cash flow, funding needs and capacity plans. Those disclosures will help show whether AI-related revenue is keeping pace with the infrastructure buildout.
