Samsung Electronics’ chip division earned an operating margin of about 72% in the third quarter, by our arithmetic from its results release. In the same quarter, global smartphone chip shipments fell 21% from a year earlier, a decline Counterpoint Research says was driven by rising memory costs.
Samsung’s own phone business reported a loss in the same quarter. Its MX and Networks Businesses reported an operating loss of KRW 0.6 trillion on KRW 37.7 trillion of revenue, and the release says their earnings “declined YoY due to cost pressures”.
Short explainer · Samsung Chips 72% vs Phone Chips -21%
A vertical news Short summarising this story. Figures come from Samsung’s Q3 2026 results release and Counterpoint Research; our arithmetic is labelled.
Business Pill · The Memory Wall
A short explainer on the memory wall, why memory capacity and bandwidth limit computing. It teaches the general idea only and says nothing about Samsung’s quarter.
The key insight: By our arithmetic, Samsung’s chip division earned about 72% operating margins in the same quarter that Counterpoint counted 21% fewer smartphone chips shipped, a 74-point gap between Samsung’s own chip and phone margins.
The release puts the Device Solutions (DS) Division, which holds the chip businesses, at KRW 106.5 trillion of operating profit on KRW 147.1 trillion of revenue. That is a margin of about 72%, and about 99% of the company’s KRW 107.4 trillion operating profit, by our arithmetic.
The Memory Business set records for quarterly revenue and operating profit “amid capacity constraints”, Samsung says. It gives the reason in one line: “Strong demand momentum for servers led to higher market prices across all applications”.
The MX and Networks margin was about minus 1.6%, by our arithmetic, and the gap between the two margins is about 74 points. The wider Device eXperience (DX) Division, which includes phones and TVs, recorded an operating loss of KRW 0.8 trillion.

What the Phone Market Reported
Counterpoint Research says global smartphone SoC shipments “declined by 21% YoY in Q3 2026, driven by rising memory costs, longer replacement cycles and cautious inventorymanagement by smartphone OEMs”.
It says smartphone memory pricegrowth slowed to 5%-10% in the third quarter from the second, and that prices are expected to rise another 5% in the fourth quarter. Counterpoint says it expects shipments to fall 20% in 2026 and another 3%-4% in 2027.
The firm adds that “Apple and Samsung were better positioned to weather the disruption”, while chipmakers UNISOC and MediaTek faced greater challenges due to their reliance on mid and low-end segments.
The Capex and the Visit
Samsung’s capital spending reached KRW 29 trillion in the quarter, up KRW 19.8 trillion from a year earlier, the release says. That puts the year-earlier quarter at KRW 9.2 trillion, and this quarter at about 3.2 times it, by our arithmetic.
On 31 October, OpenAI chief executive Sam Altman met about 50 Samsung executives in Yongin, Bloomberg reported, citing a Samsung statement. Bloomberg wrote that the talks aimed “to deepen cooperation on memory chips and AI infrastructure as global shortages intensify”.
SBS described the trip as a “sudden two-day visit” and said OpenAI’s Vice President of Hardware, Richard Ho, attended. A Bloomingbit report citing the Korea Economic Daily said SK Group Chairman Chey Tae-won hosted Altman for lunch with SK Hynix and SK Telecom executives. The same report recalls that SK and OpenAI signed a letter of intent on memory supply in October 2025, and that SK Hynix is building HBM capacity for OpenAI’s reported request of up to 900,000 DRAM wafers a month.
As we read the release, Samsung sits on both sides of the memory market: its Memory Business set records on higher prices across all applications, while its MX and Networks line, a buyer of components, reported lower earnings than a year earlier and cites cost pressures without naming memory.
As we read Counterpoint’s note, the phone makers that buy memory are trimming entry-level models and protecting margins, and the firm names rising memory costs first among three drivers of the 21% fall.
As we read the visit reports, an AI buyer went to the memory makers directly: OpenAI’s chief executive and its hardware vice president met Samsung executives, and SK’s chairman hosted Altman for lunch, two days after Samsung reported third-quarter capex about 3.2 times a year earlier, by our arithmetic.

“Strong demand momentum for servers led to higher market prices across all applications”
Three Implications
FOR PHONE MAKERS Counterpoint says some entry-level players have started using recycled memory to keep bill-of-materials costs under control, with adoption at a niche level.
FOR MEMORY MAKERS Samsung says its Memory Business set records for quarterly revenue and operating profit amid capacity constraints.
FOR AI BUYERS Bloomberg reported that Altman’s talks with Samsung aimed to deepen cooperation on memory chips and AI infrastructure.
The framework says “Memory is becoming the new compute. HBM growth is outpacing accelerator demand, making memory the rate-limiting factor in the AI scaling equation.”
As we read it, Samsung’s third quarter puts that argument into one income statement: about 72% margins in chips and a loss in phones, by our arithmetic. The framework is the owner’s argument and does not discuss Samsung’s quarter or Counterpoint’s figures.
Samsung’s release does not say how much of the MX loss came from memory prices rather than other costs. Counterpoint names three drivers of the shipment decline and does not split the 21% between them.
No new supply agreement, price or volume was reported for this visit in the readable parts of the reports, which include only the opening of Bloomberg’s article. The SK lunch report says the two sides likely discussed their AI alliance and does not name the executives present.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
In one quarter, Samsung’s chip division earned about 72% operating margins while its phone business reported an operating loss, with earnings down from a year earlier on cost pressures, and Counterpoint counted 21% fewer smartphone chips shipped worldwide, citing memory costs first. The same week, OpenAI’s chief executive went to Samsung and SK in person.
A note on sourcing. Samsung figures come from its third-quarter results release of 29 October 2026; shipment figures and forecasts from Counterpoint Research’s note of 30 October; the visit from Bloomberg, Yonhap, SBS and a Bloomingbit report citing the Korea Economic Daily. Margins, the margin gap and the capex multiple are our arithmetic. We did not contact Samsung, Counterpoint, OpenAI or SK.
