AI Agent UpdateSamsung and SK hynix face a KRW 185 trillion earnings bar as memory prices surge
Two earnings reports, one huge number, and a memory market running hot — the week ahead could set the tone for AI hardware into year-end.
The News
The memory market's biggest week of the year arrives in the next few days. SK hynix reports third-quarter results on Wednesday, October 28, and Samsung follows on Thursday, October 29. Market estimates put their combined third-quarter operating profit at roughly KRW 185 trillion, or about $139.4 billion, driven by rising memory prices and strong demand for high-bandwidth memory, the fast memory used alongside AI processors. That is an enormous bar for two companies to clear in a single quarter, and it tells you how hot the memory cycle has become.
Samsung has already given investors a preview. On October 8 it guided to third-quarter revenue of about KRW 195 trillion and operating profit of about KRW 107.4 trillion. Guidance is a company's own advance estimate, given before the full audited results, so the formal report on Thursday will confirm or adjust those numbers. Either way, the direction is clear: memory prices are rising, and the companies selling that memory are capturing the upside. Investors will also be listening for what comes next, not just what already happened.
The forward-looking question is supply of next-generation HBM4 memory for Nvidia's Vera Rubin platforms. Vera Rubin is Nvidia's next AI hardware platform, and it needs the newest, fastest memory to work at full speed. If Samsung and SK hynix can show they are on track to supply HBM4 in volume, that supports the case that the memory boom has further to run. If supply looks tight or delayed, the market will ask harder questions about how long today's prices can hold.
Two earnings reports, one huge number — the memory boom now has to prove itself in print.
Why It Matters
Memory is the unglamorous backbone of the AI boom. Every AI model runs on processors, and those processors are useless without memory fast enough to feed them data. When AI spending surges, memory demand surges with it — and because building new memory factories takes years, supply cannot catch up overnight. That scarcity is what pushes prices up, and rising prices flow almost directly into memory makers' profits. It is a simple chain, and right now every link in it is pointing the same way.
HBM is where the chain is tightest. Ordinary memory is a commodity sold in huge volumes; HBM is a specialised, stacked product made in smaller quantities for the most powerful AI systems. That makes it both more profitable and harder to scale, which is why HBM4 supply for Nvidia's Vera Rubin platforms is the question investors care about most this week. Whoever can deliver HBM4 in volume, on time, wins the most valuable orders in the memory market.
The read for ordinary investors is through the listed names. Micron (MU) is the US-listed memory peer and the easiest way to follow the cycle in dollars, while SK hynix is tracked here as SKHY and Samsung trades in Seoul. Friday's closes — Micron, SK hynix and Samsung all higher, Sandisk lower — show a market that is optimistic but selective. This week's reports will show whether that optimism was justified, and the HBM4 commentary will shape expectations for the quarters after that.
Analyst's Take
This is a Bullish setup with a high bar, which is exactly why it matters. Rising memory prices plus HBM demand is the best combination a memory maker can ask for: they sell more of the product everyone wants, at higher prices. The Friday closes underline the optimism already in the market — Micron up 2.46% to $877.55, SK hynix up 4.42% to KRW 1,277,000, and Samsung up 0.47% to KRW 215,500. One name did not join the rally: Sandisk (SNDK) fell 1.82% to $1,238.03, a reminder that even in a hot sector, not every stock moves the same way on the same day.
The risk to the bullish case is expectations, not demand. When estimates already assume roughly KRW 185 trillion of combined operating profit, merely good results may not be enough — the reports need to confirm the number and back it with a credible HBM4 supply story for Nvidia's Vera Rubin platforms. That is a demanding test, but it is the right one: memory cycles turn when supply catches up with demand, and HBM4 timing is the earliest signal of when that turn might come. For now, the evidence points up. Readers' poll: will the pair clear the KRW 185 trillion bar, or is the market asking too much?
By The Numbers
FAQ
What is HBM, and why does everyone keep talking about it?
HBM stands for high-bandwidth memory. It is a special kind of memory chip stacked in layers so it can feed data to AI processors far faster than ordinary memory. AI training needs enormous amounts of data moved quickly, so the companies building AI accelerators buy as much HBM as they can get. When HBM demand rises, memory makers' profits tend to rise with it.
What is operating profit, and how is it different from revenue?
Revenue is all the money a company brings in from selling its products. Operating profit is what is left after subtracting the day-to-day costs of running the business, like materials, factory wages and research. It is a cleaner gauge of whether the core business itself is actually making money, which is why investors watch it so closely at earnings time.
Why do you track SK hynix as SKHY and Samsung this way?
SK hynix and Samsung trade on the Seoul stock exchange, not in New York, under the tickers 000660.KS and 005930.KS. This site tracks SK hynix under the short label SKHY for its memory coverage, and Micron (MU) is the US-listed memory peer whose shares trade in dollars.
