TL;DR
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won, up 7.3 times from a year earlier, while Microsoft and Alphabet are due to report quarterly results Wednesday and Amazon on Thursday. The figures point to strong chip-sector profits, but also concentrated earnings growth, heavy cloud-company investment and uncertainty over whether AI revenue can repay that spending.
SK hynix reported preliminary third-quarter operating profit of 83.3 trillion won on Wednesday, 7.3 times its year-earlier result, as investors await quarterly results from Microsoft and Alphabet later that day and Amazon on Thursday. The contrast captures the question facing the AI boom: chip suppliers are reporting extraordinary profits, while the cloud companies funding data-center expansion still have to show how quickly AI revenue can cover their investment.
SK hynix, a major supplier of high-bandwidth memory used alongside AI processors, said quarterly revenue reached 104.6 trillion won, up 328% from a year earlier and the first time it exceeded 100 trillion won. Operating margin was 80%. The company’s release was preliminary and unaudited. Net profit was 39.8 trillion won, down 58% from the prior quarter, which the source account 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. 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 buyback for the quarter; the source says half of the buyback is intended for employee compensation and is not counted by the company as a shareholder return.
The broader numbers show both growth and exposure. FactSet’s blended estimate put S&P 500 third-quarter earnings growth at 29.5% as of October 23. In an October 19 analysis, FactSet’s John Butters estimated that removing Micron and Nvidia would lower the index growth rate from 29.0% to 20.0%. These are estimates, not final reported earnings, and some of the biggest companies had yet to report.

AI Profits Meet the Payback Test
The results matter because the AI investment cycle is producing different signals at different points in the supply chain. SK hynix’s figures show that demand for memory used in AI infrastructure is translating into reported revenue and operating profit. For cloud providers, however, building and equipping data centers requires substantial spending before the returns are fully visible.
Alphabet, Amazon, Microsoft and Meta are expected to spend a combined roughly $725 billion to $745 billion in 2026, according to the source’s sum of company guidance. Analysts expect Alphabet and Amazon to report negative free cash flow again for the third quarter. The results and management commentary will help investors judge whether cloud growth, cash generation and planned capacity are keeping pace with that spending. They will not, by themselves, settle whether the investments will ultimately earn an adequate return.
The gains are also concentrated. The estimate that Micron and Nvidia account for a large share of expected US earnings growth means strong headline index figures do not describe every company equally. Removing those two still leaves an estimated 20% growth rate in the FactSet comparison, but the result underlines how much the broader picture depends on a small number of chipmakers.

Six Figures Behind the AI Cycle
The source frames the moment through six measures: SK hynix’s operating profit; the contribution of Micron and Nvidia to expected S&P 500 growth; planned spending by four major technology companies; expected free cash flow at Alphabet and Amazon; US shipments and orders for capital goods; and the decline in China’s STAR50 index. Together, they distinguish current results from forecasts and market signals.
In the United States, 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 source. Those data offer evidence that investment is reaching the wider economy, but they do not show how much of the activity is specifically tied to AI or whether it will generate returns.
China offers a contrasting market signal. Reuters reported that the STAR50 index, which includes Chinese AI and chip companies, had fallen 40% in under four months by October 26, erasing about $480 billion in market value. The source says the index still traded at around 100 times past earnings. A sharp market decline alongside a high valuation illustrates volatility, but does not alone establish whether the sector’s business prospects have changed.
“Demand is expected to exceed supply through 2030.”

The Unknowns Behind AI Returns
The central unknown is whether revenue from AI services and cloud computing will grow enough to justify the capital being committed to infrastructure. The companies’ quarterly results may provide updates on cloud growth, spending plans, cash flow and capacity, but they cannot establish the long-term return on investment.
Some of the earnings figures are still estimates, and several major contributors had not reported at the time of the preview. Comparisons can also be affected by unusual items in the prior-year quarter: FactSet noted one-time charges at Meta, EchoStar and Boeing. The source does not provide final results from the upcoming Big Tech reports, or a confirmed measure of how much of the companies’ spending is generating AI-specific revenue.
SK hynix’s demand outlook is its own projection, and the reason its net profit fell from the previous quarter is described only as non-operating items. The available information does not establish the future path of memory supply, the durability of current prices or whether the market decline in China reflects changing business fundamentals.
Big Tech Results Set the Next Test
Microsoft and Alphabet are scheduled to report quarterly results on Wednesday, October 28, followed by Amazon on Thursday, October 29. Investors will be watching capital-spending guidance, cloud growth, free cash flow and capacity plans—the four measures identified in the source as key tests of whether the AI buildout is progressing in step with its costs.
Those reports will show what the companies have disclosed for the latest quarter and whether they have changed their outlook. A fuller assessment will require comparing spending with revenue and cash generation over time. The source was written as a preview before the results and says it would add a dated update afterward; no post-report figures are included in the material provided here.
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 company reported an 80% operating margin.
Why are Microsoft, Alphabet and Amazon’s results relevant?
These companies are among the major investors in data centers and AI infrastructure. Their reported cloud growth, capital spending and free cash flow will give readers more information about whether revenue and cash generation are keeping pace with investment.
How much are the major technology companies expected to spend?
The source estimates that Alphabet, Amazon, Microsoft and Meta plan to spend roughly $725 billion to $745 billion in 2026, based on its sum of company guidance. This is an estimate of planned spending, not a final tally of actual expenditure.
Is the AI boom already proven to be profitable?
SK hynix’s reported figures show strong profits for a major memory supplier. But the provided information does not establish whether the wider investment in AI infrastructure will generate sufficient returns over time. That depends in part on future revenue and cash flow from the companies making the investment.
