On Thursday morning, Samsung Electronics told the world it had earned roughly 107.4 trillion won in operating profit over three months. That is about $80.2 billion, according to CNBC’s conversion, and it is the first time a South Korean company has crossed the 100 trillion won line in a single quarter, as SBS reported. A year ago, the same quarter produced 12.17 trillion won.
The market’s response was a shrug. Samsung shares and the benchmark KOSPI both slipped slightly in early trading, which says as much about the AI hardware boom as the record itself.
What Samsung actually reported
The company published its third-quarter guidance at 07:49 Seoul time on October 8, in a release on its global newsroom. It put consolidated sales at about 195 trillion won and operating profit at about 107.40 trillion won. Korean disclosure rules do not allow ranges, so those numbers are midpoints of 194 to 196 trillion won and 107.3 to 107.5 trillion won.
The jump is hard to overstate. The previous quarter, Samsung posted 89.49 trillion won in operating profit on 171.5 trillion won in sales. Against the third quarter of 2025, operating profit is up about 782.5 percent and sales about 126.6 percent, figures that match both SBS’s reporting and a calculation from Samsung’s own numbers.
Our own arithmetic puts the operating margin near 55 percent. Samsung did not state that figure itself, but it shows how unusual the quarter is for a company that sells everything from phones to appliances.
The result also edged past expectations. LSEG’s SmartEstimate pointed to roughly 106.1 trillion won, and Yonhap Infomax’s consensus sat near 105.75 trillion won.
These are preliminary numbers. The release contains headline figures only, with no executive comment and no breakdown by division.
Memory is carrying the company
Samsung did not say which business produced the profit, but the picture from outside is consistent. Reuters reported, in a version carried by Emirates 24|7, that surging demand for AI chips lifted memory sales. SBS wrote that the Device Solutions division, and memory in particular, is believed to have generated nearly all of the profit, while consumer-device units probably lost money.
Treat those divisional claims as analyst estimates until Samsung publishes its full results. Still, the reported scale of the gap is striking. Analysts cited by Reuters suggest Samsung’s mobile business lost more than $1 billion in the quarter, which would mean one of the world’s best-known phone makers is being subsidized by its chip memory lines.
That helps explain why the company’s fortunes have swung so sharply. Samsung’s earlier record, 17.6 trillion won in the third quarter of 2018, stood for years. When Samsung guided to about 20 trillion won for the fourth quarter of 2025, it broke that mark, and the new figure is more than five times as large.
How it compares with Nvidia
It is tempting to line Samsung up against the company most associated with the AI boom. In its 10-Q filing, Nvidia reported GAAP operating income of $63.734 billion for the quarter ended July 26, 2026. Samsung’s guidance is higher on that raw measure.
Two cautions apply. The companies’ fiscal calendars do not line up, and their accounting standards differ, so the comparison is a rough one rather than a clean ranking.
The more interesting link between the two is cost. Nvidia said in August that its 75 percent gross margin was under pressure from rising memory and wafer prices, and it guided to 74 percent. In other words, part of Samsung’s windfall is money that its customers are paying.
Why the stock did not celebrate
The quiet reaction in Seoul had been building. On October 7, the KOSPI fell 1.98 percent to close at 6,803.90 on foreign selling, and Samsung closed at 268,500 won. By 10:30 a.m. on Thursday, AJP showed the index down 0.2 percent at 6,793.26 and Samsung down 0.2 percent at 268,000 won. Those are intraday readings, not closing prices.
AJP noted that much of the optimism looked to be priced in already. Samsung’s stock is down more than 25 percent from its June record high amid doubts about how long the AI boom can last. A record profit has not settled that argument.
Kiwoom Securities analyst Han Ji-young, speaking to Chosunbiz, said in substance that the market is likely to stay volatile as it digests the results, and that investors should follow Samsung’s share price, foreign flows and revisions to 2027 estimates.
The memory price question
The central variable is price. TrendForce expects conventional DRAM contract prices to rise 10 to 15 percent quarter on quarter in the fourth quarter. That is still an increase, but a gentle one next to the roughly 60 percent surge in the second quarter. The slowdown is being watched closely, because Samsung’s profit has depended so heavily on how much customers will pay.
Competition matters as well. Counterpoint said Samsung regained the top spot in DRAM revenue from SK Hynix in the fourth quarter of 2025, while SK Hynix held 57 percent of the market for high-bandwidth memory, the specialized chips used in AI accelerators. Samsung’s headline number says little about how that second contest is going.
What to watch next
The detail is still to come. Benzinga reports that Samsung will publish division-level results on October 29, though the company’s release does not give a date. That report, and the accompanying earnings call, should show how much of the profit came from memory and how deep the losses in other units run. Investors are expected to listen for any news on shareholder returns.
Before that, SK Hynix reports its own quarter, which aggregators place on October 27 or 28 (not confirmed by the company). Charles Schwab’s market note points to ASML and Taiwan Semiconductor reporting next week, which will give an early read on the wider chip sector.
For now, Samsung has proven that the AI boom can produce profit on a scale no South Korean company had reached. The harder question is whether it can hold that level when memory price increases slow and the market is already treating the record as old news.
