TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, about 7.3 times its result a year earlier, as Microsoft and Alphabet prepared to report and Amazon followed Thursday. The figures show strong chip-sector profits alongside concentrated US earnings growth and rising investment; whether cloud revenue and cash generation can justify that spending remains unproven.
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won on Wednesday, about 7.3 times its result a year earlier, as investors awaited quarterly results from Microsoft and Alphabet that night and Amazon on Thursday. The contrast puts a central question about the AI buildout in focus: chip demand is producing striking profits, but the cash returns from the cloud companies’ heavy spending have yet to be established.
SK hynix, a major supplier of high-bandwidth memory used alongside AI processors, reported revenue of 104.6 trillion won, up 328% year over year, and operating profit of 83.3 trillion won, up 632% from 11.4 trillion won. Its reported operating margin was 80%. The company said long-term agreements with 14 major customers cover more than half of its expected 2027 and 2028 capacity. Its results are preliminary and unaudited.
The bottom line was less straightforward: net profit was 39.8 trillion won, down 58% from the previous quarter, which the source material attributes to non-operating items. SK hynix expects demand to exceed supply through 2030, but that is the company’s forecast, not an independently verified outcome. It also announced a 14 trillion won dividend and a 20 trillion won buyback for the quarter; the company says half of the buyback relates to employee compensation and is not counted as a shareholder return.
The wider earnings picture is strong but concentrated, according to FactSet estimates cited in the source material. FactSet’s blended estimate for S&P 500 third-quarter earnings growth was 29.5% as of October 23. In an October 19 calculation, removing Micron and Nvidia lowered the estimated growth rate from 29.0% to 20.0%. These are estimates, and several major companies had not yet reported when the figures were compiled.

The AI Boom’s Profit Test
The figures point to different stages of the same investment cycle. Memory and chip suppliers are already reporting large profits, while cloud companies are spending to build data centers and expand AI capacity. The key test in the upcoming reports is whether revenue growth and cash generation are keeping pace with that investment.
Alphabet, Amazon, Microsoft and Meta together plan roughly $725 billion to $745 billion in capital spending for 2026, based on the source author’s sum of company guidance. That scale matters beyond the companies themselves: spending on servers, chips, power and facilities can support suppliers and affect the wider economy, while weak returns could pressure cash flow and investor expectations. The spending total is a forecast based on guidance, not money already spent.
Market gains are also uneven. Strong results from a small number of chipmakers can lift aggregate earnings estimates without showing that AI investment is paying off broadly across companies. Conversely, a 20% growth estimate excluding Micron and Nvidia would still represent substantial growth if realized. Neither aggregate figure alone settles whether today’s spending will earn an adequate return.

From Chip Profits to Cloud Spending
SK hynix’s report arrived amid sharply different market signals. Its shares rose during the Seoul session, according to CNBC’s reporting cited in the source material. Meanwhile, Reuters reported on October 26 that China’s STAR50 index, which includes AI and chip companies, had fallen 40% since July, erasing about $480 billion in value. The index was still trading at around 100 times past earnings, Reuters reported. Those figures describe a particular index and period; they do not establish that all Chinese or global AI companies have followed the same path.
US economic data offer another piece of the picture. The Census Bureau reported that 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 the source material. These indicators are consistent with investment in equipment, but do not isolate how much was driven by AI or show whether the spending will generate profits.
SK hynix’s own actions also show that strong operating results do not remove market risk. The source reports that its chief executive said the company had stopped reviewing a pre-IPO funding round or listing for its US unit, Solidigm, citing market volatility and a correction in semiconductor stocks. The report does not provide further details of that decision.
“The company expects demand to exceed supply “through 2030.””

Returns and Demand Still Unclear
The upcoming earnings reports may provide evidence about AI-related revenue and investment, but they will not by themselves settle the long-term return question. The source material says analysts expect Alphabet and Amazon to report negative free cash flow again for the third quarter; those expectations need to be checked against the companies’ results. It does not provide comparable confirmed figures for all four major spenders or a complete breakdown of AI revenue.
Other uncertainties include how much of the earnings growth attributed to chipmakers reflects durable demand, how quickly new data-center capacity will be used, and whether customer commitments translate into sustained orders. SK hynix’s capacity agreements and outlook are company statements. The source material also does not establish that the sharp decline in the STAR50 index predicts the performance of other markets.
Watch the Earnings Releases
Microsoft and Alphabet are scheduled to report quarterly results on the evening of October 28, followed by Amazon on Thursday. Readers should compare capital-spending guidance with cloud growth, examine free cash flow and ask what management says about capacity, demand and funding. The source material identifies those as the main figures to watch; the reports will determine which are available and comparable.
This article is a preview based on information available before those results. The source says a dated update is planned after the releases. Any conclusions should distinguish reported results from management forecasts and analyst estimates, and should not treat a single quarter as proof of long-term returns.
Key Questions
What is the main news behind this preview?
SK hynix reported preliminary record quarterly operating profit on October 28, just before Microsoft and Alphabet were due to report and Amazon to follow. The timing makes its chip results a contrast with the cloud companies’ large AI-related investment plans.
How much did SK hynix’s operating profit rise?
The company reported 83.3 trillion won in third-quarter operating profit, up 632% from 11.4 trillion won a year earlier, or about 7.3 times the year-earlier figure. The results were preliminary and unaudited.
Why are Micron and Nvidia important to the earnings figures?
FactSet’s October 19 calculation said removing those two companies lowered estimated S&P 500 third-quarter earnings growth from 29.0% to 20.0%. The numbers are estimates, and the calculation illustrates concentration rather than proving that growth elsewhere is weak.
What should readers look for in the Big Tech reports?
Compare capital-spending plans with cloud growth and free cash flow, and note what executives say about capacity and funding. Those measures can help show whether investment is accompanied by revenue and cash generation, though they cannot establish long-term returns on their own.
