TL;DR
SK hynix reported record third-quarter revenue and operating profit on Oct. 28, while China’s STAR50 index has fallen about 40% since July. Ahead of results from Microsoft, Alphabet and Amazon, six indicators point to a real but concentrated AI boom whose long-term returns remain unproven.
SK hynix reported its strongest quarter on record on Oct. 28, with operating profit more than seven times its year-earlier level, as investors prepared for quarterly results from Microsoft and Alphabet that night and Amazon on Thursday. The contrasting signals—a record chipmaker result, heavy planned AI spending and a sharp fall in Chinese AI-related shares—make the earnings a test of whether AI demand is translating into durable returns.
SK hynix, a supplier of high-bandwidth memory used alongside AI processors, reported preliminary, unaudited third-quarter revenue of 104.6 trillion won, up 328% from a year earlier. Operating profit reached 83.3 trillion won, compared with 11.4 trillion won a year earlier, and its operating margin was 80%. Net profit, however, fell 58% from the previous quarter to 39.8 trillion won, which the company attributed to non-operating items. The measures show why operating performance and bottom-line profit can tell different stories.
The company said long-term agreements with 14 major customers cover more than half of its production capacity for 2027 and 2028. SK hynix expects demand to exceed supply through 2030; that is a company forecast, not an established outcome. It also announced a 14 trillion won dividend and a 20 trillion won buyback for the quarter. The source material says roughly half of the buyback is tied to employee compensation, so the full amount should not be treated as a direct shareholder payout.
Other indicators offer a less uniform picture. FactSet’s Oct. 19 analysis estimated that removing Micron and Nvidia would reduce projected third-quarter S&P 500 earnings growth from 29% to 20%. Separately, the source reports that Alphabet, Amazon, Microsoft and Meta together plan about $725 billion to $745 billion in 2026 capital spending, based on the author’s sum of company guidance. U.S. core capital-goods shipments 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.

AI Profits Meet Spending Tests
The results matter because chip suppliers’ profits are arriving before the full cost and payoff of AI infrastructure are clear. SK hynix’s margins show strong current demand for memory, but a single supplier’s quarter cannot establish whether the whole market will sustain that pace. The earnings concentration estimate also suggests that a small number of companies account for a substantial share of projected U.S. growth.
For cloud companies, investors will be comparing AI-related revenue growth with capital spending and cash generation. The source says analysts expect Alphabet and Amazon to report negative free cash flow again for the third quarter. That is an analyst expectation, not a reported result. If spending rises faster than cash returns, investors may question the timing and scale of investments; if cloud growth and cash generation improve, the case for continued investment could strengthen.
The signals differ by region and by business. The reported strength of memory demand and U.S. equipment orders contrasts with the fall in Chinese AI and chip shares. Together they suggest that “AI boom” is not a single market-wide condition: current profits, stock valuations, infrastructure spending and eventual returns need to be judged separately.

Six Signals Behind the Earnings
The source frames the earnings preview around six indicators: SK hynix’s record results; the concentration of projected U.S. earnings growth in Micron and Nvidia; planned capital spending by four major technology companies; expected free cash flow at Alphabet and Amazon; U.S. shipments and orders for capital goods; and the decline in China’s STAR50 index. Each measures a different part of the AI economy, and none alone establishes whether the boom is sustainable.
FactSet’s Oct. 23 blended estimate put S&P 500 third-quarter earnings growth at 29.5%. Its Oct. 19 contributor analysis said the estimate would fall from 29.0% to 20.0% if Micron and Nvidia were excluded. Those figures are estimates and use dates and calculations specified by FactSet; several large contributors, including Nvidia, had not yet reported. The source also notes that comparisons for some companies may be affected by one-time charges in the prior-year quarter.
In China, Reuters reported that the STAR50 index had lost about 40% since July and erased roughly $480 billion in value by Oct. 26, while trading at around 100 times past earnings. The index’s decline is a market signal, not proof that AI demand has reversed. The source’s account also says SK hynix shares rose during the Seoul session, while the company halted a review of funding or a possible listing for its U.S. unit Solidigm, citing market volatility and a correction in semiconductor stocks.
“The company expects demand to exceed supply through 2030.”

Returns and Demand Remain Unsettled
The earnings reports had not yet been released when the preview was published, so the actual results, updated spending plans and management commentary from Microsoft, Alphabet and Amazon remain unknown. The source does not provide a later update. It is also unclear how much of the planned spending will generate revenue, how quickly AI services can contribute to cash flow, or whether current memory demand will persist at the level SK hynix forecasts.
The earnings-growth figures are projections, not final results, and their concentration depends on estimates for companies that had not reported. The Chinese share-market decline and U.S. equipment data offer useful but incomplete evidence: they cannot by themselves establish the strength of global AI demand or the value companies will ultimately earn from their investments.
Earnings Will Test the Payback
Microsoft and Alphabet were scheduled to report on Oct. 28, followed by Amazon on Oct. 29. Readers should compare each company’s capital-spending guidance with cloud growth, free cash flow and comments about infrastructure capacity. Those figures can clarify whether AI demand is keeping pace with investment, though one quarter will not settle the longer-term question of returns.
The source said it would add a short, dated update after the companies reported. Until those results and any updated guidance are available, the central measure is not spending alone but whether companies can show that investment is supporting growth and cash generation.
Key Questions
What is the main development?
SK hynix reported record third-quarter revenue and operating profit on Oct. 28, ahead of quarterly results from Microsoft, Alphabet and Amazon that investors were watching for evidence of AI demand and returns.
What were SK hynix’s third-quarter results?
The company reported preliminary, unaudited revenue of 104.6 trillion won and operating profit of 83.3 trillion won. Operating profit was 7.3 times the year-earlier figure; net profit fell 58% from the previous quarter to 39.8 trillion won.
Why does earnings concentration matter?
FactSet estimated that removing Micron and Nvidia would lower projected S&P 500 third-quarter earnings growth from 29% to 20%. The figures are estimates, and several companies in the analysis had not reported.
What should investors watch in the Big Tech reports?
Key measures include capital-spending guidance, cloud growth, free cash flow and capacity plans. Comparing those indicators can help show whether AI-related business growth is keeping pace with infrastructure investment.
Does the STAR50 decline prove China’s AI boom has ended?
No. The source reports that the index fell about 40% since July, but a share-price decline alone does not establish that underlying AI demand has ended. The index’s valuation and the broader market picture remain separate considerations.
