Samsung Electronics was once the dominant player in a type of semiconductor known as memory, putting it in a great position to capitalize on the boom of artificial intelligence.
But the South Korea electronics giant has now fallen behind its long-time rival SK Hynix in next-generation chips that have been key component for AI silicon leader Nvidia. The result? Samsung’s profit has plunged, around $126 billion has been wiped off its market value, according to data from S&P Capital IQ, and an executive issued a rare public apology about the company’s recent financial performance.
Memory is a critical type of chip used to store data, and it can be found in a plethora of devices from smartphones to laptops. For years, Samsung was the undeniable leader in this technology, ahead of South Korean rival SK Hynix and U.S. competitor Micron.
But as AI applications such as OpenAI’s ChatGPT rose in popularity, the underlying infrastructure required to train the huge models they rely on became a bigger focus. Nvidia has emerged as the top player in this space with its graphics processing units (GPUs) that have become the gold standard used by tech giants for AI training.
A crucial part of that semiconductor architecture is high-bandwidth memory, or HBM. This next generation of memory involves stacking multiple dynamic random access memory (DRAM) chips, but it had a small market before the AI boom.
That’s where Samsung got caught out and failed to invest.
“HBM has been a very niche product … for a long time and Samsung has not focused its resources on its development,” Kazunori Ito, director of equity research at Morningstar, told CNBC by email.
“Due to the difficulty of the technology involved in stacking DRAMs and the small size of the addressable market, it was believed that the high development costs were not justified.”
SK Hynix saw this opportunity. The company aggressively launched HBM chips which were approved for use in Nvidia architecture and, in the process, the South Korean firm established a close relationship with the U.S. giant. Nvidia’s CEO even asked the company to speed up supply of its next generation chip, underscoring the importance of HBM to its products.
“With strong R&D (research and development) investments and established industry partnerships, SK Hynix maintains an edge in both HBM innovation and market penetration,” Brady Wang, associated director at Counterpoint Research, told CNBC by email.
Samsung told CNBC that, in the third quarter, total HBM sales grew more than 70% quarter-on-quarter. The tech giant added that the current product known as HBM3E is in mass production and generating sales.
The South Korean tech company noted that development for its next-generation HBM4 is “underway according to plan” and that the company is targeting starting “mass production” in the second half of 2025.
Can Samsung make a comeback?
Analysts said that Samsung is lagging behind competitors for a number of reasons, including underinvestment in HBM and the fact that it is not a first-mover.
“It is fair to say that Samsung has not been able to close the gap with SK Hynix on the HBM development roadmap,” Morningstar’s Ito said.
Samsung’s ability to make a comeback in the short term appears to be closely linked to Nvidia.
A company must pass a strict qualification process before Nvidia approves it as a HBM supplier — and Samsung has not yet completed this verification. But a green light from Nvidia could open the door for Samsung to return to growth and compete more effectively with SK Hynix, according to analysts.
“Since NVIDIA holds more than 90% of the AI chip market, where most HBMs are used, NVIDIA’s approval is critical for Samsung to benefit from the robust demand for AI servers,” Ito said.
A Samsung spokesperson said that the company has made “meaning progress” regarding HBM3E and has “completed an important phase in the qualification process.”
“We expect to start expanding sales in the fourth quarter,” the spokesperson said.
Meanwhile, Wang noted that Samsung’s strength in research and development, as well as the company’s semiconductor manufacturing capacity that could help it catch up to SK Hynix.

OpenAI on Monday said the U.S. needs to substantially ramp up its investment in new energy capacity if it wants to stay ahead of China in the race to develop artificial intelligence.
“Electricity is not simply a utility,” OpenAI said in a blog post Tuesday. “It’s a strategic asset that is critical to building the AI infrastructure that will secure our leadership on the most consequential technology since electricity itself.”

OpenAI shared an 11-page submission with the White House Office of Science and Technology Policy, in which it encouraged the U.S. to commit to building 100 gigawatts of new energy capacity each year.
A gigawatt is a measure of power, and 10 gigawatts is roughly equivalent to the annual power consumption of 8 million U.S. households, according to a CNBC analysis of data from the Energy Information Administration.
OpenAI said that China added 429 gigawatts of new power capacity last year, while the U.S. added 51 gigawatts. The company said this disparity is creating an “electron gap” that is putting the U.S. at risk of falling behind.
Amazon is preparing to announce sweeping job cuts beginning Tuesday, CNBC has learned.
The layoffs will amount to the largest cuts to Amazon’s corporate workforce in the company’s history, spanning almost every business, according to a person familiar with the matter, who asked not to be named because the details are confidential.
Amazon is expected to begin informing employees of the layoffs via email Tuesday morning, the person said.
The company plans to lay off as many as 30,000 staffers across its corporate workforce, according to Reuters, which first reported the news.
Amazon declined to comment.
Amazon is the nation’s second-largest private employer, with more than 1.54 million staffers globally as of the end of the second quarter. That figure is primarily made up of its warehouse workforce. It has roughly 350,000 corporate employees.
The planned layoffs would also represent the biggest job cuts across the tech industry since at least 2020, according to Layoffs.fyi. As of Monday, more than 200 tech companies have laid off approximately 98,000 employees since the start of the year, according to the site, which monitors job cuts in the tech sector.
Microsoft has laid off about 15,000 people so far this year, while Meta last week eliminated roughly 600 jobs within its artificial intelligence unit. Google cut more than 100 design-related roles in its cloud unit earlier this month, and Salesforce CEO Marc Benioff said in September the company laid off 4,000 customer support staffers, pointing to its increasing AI adoption as a catalyst behind the cuts. Intel‘s cuts this year totaled 22,000 jobs, the most of any listed by Layoffs.fyi.
The steepest year for job cuts in tech came in 2023, as the industry reckoned with soaring inflation and rising interest rates. Close to 1,200 tech companies slashed over 260,000 jobs, the site said.
Over the past year, companies across industries including tech, banking, auto and retail have also pointed to the rise of generative AI as a force that’s likely to or already changing size of their workforces.
Amazon has conducted rolling layoffs across the company since 2022, which has resulted in more than 27,000 employees being let go. Job reductions have continued this year, though at a smaller scale. Amazon’s cloud, stores, communications and devices divisions have been hit with layoffs in recent months.
The layoffs are part of a broader cost-cutting campaign by Amazon CEO Andy Jassy that began during the Covid-19 pandemic. Jassy has also moved to simplify Amazon’s corporate structure by having fewer managers in order to “remove layers and flatten organizations.”
Jassy said in June that Amazon’s workforce could shrink further as a result of the company embracing generative AI, telling staffers that the company “will need fewer people doing some of the jobs that are being done today, and more people doing other types of jobs.”
“It’s hard to know exactly where this nets out over time, but in the next few years, we expect that this will reduce our total corporate workforce,” Jassy said in the June memo to staff.

Shares of iRobot plunged more than 30% on Monday after the company warned its search for a buyer has hit a substantial roadblock and its financial condition remains dire.
The Roomba maker has been vying to sell itself since March, but last week, the only remaining potential buyer withdrew from the process following a “lengthy period of exclusive negotiations,” iRobot disclosed in a regulatory filing.
Since then, iRobot has struggled to generate cash and pay off debts, and in March warned there’s “substantial doubt” about its ability to stay in business.
Amazon CEO Andy Jassy called regulators’ efforts to block the deal a “sad story,” arguing it would’ve allowed iRobot to scale and compete against rapidly growing rivals, such as China-based Anker, Ecovacs and Roborock.

iRobot said Monday its last remaining bidder offered a price per share that was “significantly lower” than its stock price over recent months. Shares of iRobot are down more than 50% this year.
“We currently are not in advanced negotiations with any alternative counterparties to a potential sale or strategic transaction,” iRobot wrote in the filing. “As such, there remains no assurance that our review of strategic alternatives will result in any transaction or outcome.”
In July 2023, iRobot took a $200 million loan from the Carlyle Group to fund its operations as a stopgap until the Amazon deal closed. iRobot said in the filing that it extended the waiver period for certain financial obligations until Dec. 1, its sixth amendment to the credit agreement.
The filing warns that if lenders don’t provide additional funding or if it can’t secure other sources of capital in the near term, it “may be forced to significantly curtail or cease operations and would likely see bankruptcy protection.”
