South Korean memory chipmaker SK Hynix said Friday that it was ready to mass produce its next-generation high-bandwidth memory chips, staying ahead of rivals and sending the company’s stock soaring.
HBM is a type of memory that is used in chipsets for artificial-intelligence computing, including in chips from global AI giant Nvidia — a major client of SK Hynix.
According to its announcement Friday, the company has finished its internal validation and quality assurance process for HBM4 and is ready to manufacture those at scale.
“Completion of HBM4 development will be a new milestone for the industry,” said Joohwan Cho, head of HBM development at SK Hynix.
HBM4 is the sixth generation of HBM technology — a type of Dynamic Random Access Memory, or DRAM. DRAM can be found in personal computers, workstations and servers and is used to store data and program code.
SK Hynix’s latest HBM4 product has doubled bandwidth and increased power efficiency by 40% compared to the previous generation, according to the company.
Notably, HBM4 is expected to be the main AI memory chip needed for Nvidia’s next-generation Rubin architecture — a more powerful AI chip for global data centers — said Dan Nystedt, vice-president at TriOrient, an Asia-based private investment firm with a focus on semiconductors.
“SK Hynix is a key supplier for Nvidia, and the announcement shows it remains far ahead of rivals,” he said.
Samsung Electronics and Micron have struggled to catch up to SK Hynix in HBM, as it builds on its segment leadership and benefits from being Nvidia’s main HBM supplier.
However, the companies have made some progress. Micron has also shipped samples of its HBM4 products to customers, while Samsung has reportedly been working to get its HBM4 chips certified by Nvidia.
“Despite the shifting competitive landscape, we anticipate SK Hynix will maintain a commanding position, potentially securing around 50% of the HBM market share by 2026,” said MS Hwang, research director at Counterpoint Research, covering memory solutions.
SK Hynix shares rose more than 7% Friday to hit their highest since 2000, following its chip announcement, bringing year-to-date gains to nearly 90%. Shares of Samsung Electronics and Micron have risen over 40% and nearly 80% in 2025, respectively.
SK Hynix posted record operating profit and revenue for its June-quarter, thanks to strong HBM demand, which accounted for 77% of its overall revenues. The company’s market capitalization has increased by more than $80 billion since the start of the year, according to data from S&P Capital IQ.
The firm expects to double HBM sales for the full year compared to 2024, and for demand from AI to continue to grow into 2026.
OpenAI CEO Sam Altman speaks to media following a Q&A at the OpenAI data center in Abilene, Texas, U.S., Sept. 23, 2025.

OpenAI CEO Sam Altman said Thursday that the artificial intelligence startup is on track to generate more than $20 billion in annualized revenue run rate this year, with plans to grow to hundreds of billions in sales by 2030.
The company has inked more than $1.4 trillion of infrastructure deals in recent months to try and build out the data centers it says are needed to meet growing demand. The staggering sum has raised questions from investors and others in the industry about where OpenAI will come up with the money.
“We are trying to build the infrastructure for a future economy powered by AI, and given everything we see on the horizon in our research program, this is the time to invest to be really scaling up our technology,” Altman wrote in a post on X. “Massive infrastructure projects take quite awhile to build, so we have to start now.”
OpenAI was founded as a nonprofit research lab in 2015, but has become one of the fastest-growing commercial entities on the planet following the launch of its chatbot ChatGPT in 2022. The startup is currently valued at $500 billion, though it’s still not profitable.
In September, OpenAI CFO Sarah Friar told CNBC that OpenAI was on track to generate $13 billion in revenue this year.
Friar caught the attention of the Trump administration this week after she saying at at event that OpenAI is looking to create an ecosystem of banks, private equity and a federal “backstop” or “guarantee” that could help the company finance its investments in cutting-edge chips.
She clarified those comments late Wednesday, writing in a post on LinkedIn that OpenAI is not seeking a government backstop for its infrastructure commitments.
“I used the word ‘backstop’ and it muddied the point,” Friar wrote. “As the full clip of my answer shows, I was making the point that American strength in technology will come from building real industrial capacity which requires the private sector and government playing their part.”
Venture capitalist David Sacks, who is serving as President Donald Trump’s AI and crypto czar, said Thursday that there will be “no federal bailout for AI.” He wrote in a post on X that if one frontier model company in the U.S. fails, another will take its place.
Altman said Thursday that OpenAI does “not have or want government guarantees for OpenAI datacenters.” He said taxpayers should not bail out companies that make poor decisions, and that “if we get it wrong, that’s on us.”
“This is the bet we are making, and given our vantage point, we feel good about it,” Altman wrote. “But we of course could be wrong, and the market—not the government—will deal with it if we are.”
Every weekday, the CNBC Investing Club with Jim Cramer releases the Homestretch — an actionable afternoon update, just in time for the last hour of trading on Wall Street. Markets: Stocks tumbled Thursday as concerns about eye-watering valuations in AI-linked names persisted. The S & P 500 shed nearly 1% in afternoon trading. But the market’s big laggards were in tech, as the Nasdaq retreated more than 1%. Club holdings Nvidia and Meta Platforms declined 2.8% and 2%, respectively. Investors also looked at fresh economic data that indicated a massive increase in corporate layoffs. Job cuts last month reached their highest level of any October reading in over two decades, according to outplacement firm Challenger, Gray & Christmas. The government’s ongoing shutdown is likely playing a hand in it Big Tech news: Apple is nearing a deal to use Google ‘s AI model in a revamped version of Siri, according to Bloomberg . The iPhone maker, as part of the agreement, would pay Alphabet ‘s Google around $1 billion each year. Jim called it a “terrific deal” during “Squawk on the Street” on Thursday. He added, “I love this combination,” even if there’s some debate about whether the payment should be going the other way. The partnership would be a step in the right direction for Club name Apple’s so-far rocky rollout of its generative AI offerings. Apple Intelligence, the company’s AI suite, has faced many delays. Management has postponed its AI-enhanced Siri until at least 2026. Making matters worse, Big Tech peers like Meta have continued to poach top AI talent from Apple, as well. Still, we continue to believe that Apple doesn’t need to be first to market. The company just needs to be the best. Costco premium: Shares slipped more than 1% on Thursday despite the retailer posting solid October sales. Costco ‘s U.S. core comparable sales, excluding gas price and foreign exchange fluctuations, were up 6.7% for the four weeks ending Nov. 2 — shy of Wall Street’s estimates of 7% to 8%. That’s still a strong showing, given how many consumer-focused names have stumbled recently due to concerns about the weakening consumer. Wells Fargo described the Costco figures as “good results in a choppy retail tape,” but cautioned that “everything matters at this valuation.” That makes further stock upside hard to justify, according to the analysts. But the Club holding’s premium remains a key focus. Shares currently trade at 47 times forward earnings, lower than the 52 times forward earnings figure earlier this year. This brings Costco’s multiple closer to its recent historical average. Oppenheimer analysts on Monday said the lower multiple makes Costco shares more attractive, and they view the stock’s recent decline as a buying opportunity. Jim agrees. “I want to buy Costco,” he said Monday . Although a multiple above 50 can feel “dangerous” for some investors, Jim believes it is not a good enough reason to stay away. Though the stock still trades above the Club’s cost basis, Jim doesn’t expect a major pullback. Costco deserves its premium. The retailer’s subscription-based model delivers reliable and high-margin recurring revenues that traditional retailers just can’t match. Betting partner: Disney announced Thursday that DraftKings would be ESPN’s new official sportsbook and odds provider, bringing an end to its Penn Entertainment partnership. The change will take effect Dec. 1, but a full rollout of the integration is not expected until 2026. The decision to part ways with Penn comes just two years into working together. The two entered into a partnership in August 2023, with a 10-year agreement that allowed either party to exit after the third year if certain market share goals weren’t met. Both have now mutually agreed to wind down that operation. Under the new deal, ESPN will work with DraftKings to “continue to super-serve passionate sports fans and grow our ESPN direct-to-consumer business,” said ESPN chairman Jimmy Pitaro in a statement. The partnership could strengthen Disney’s broader direct-to-consumer (DTC) strategy, where ESPN plays a crucial role in the Disney+ streaming bundle. Disney’s DTC business is viewed as a long-term driver of earnings growth. If the DraftKings alliance helps boost engagement and monetization within the ESPN ecosystem, it could serve as a much-needed catalyst for Disney’s stock. Shares are down roughly 1% year-to-date, compared to the S & P 500’s 14.5% advance. Up next: Club holding Texas Roadhouse reports earnings after Thursday’s close. Qnity , the new Club name that just spun off from DuPont , is scheduled to hold a business update call after the close. (DuPont reported pretty solid earnings before the bell.)

Meta projected that 10% of its overall sales in 2024, or about $16 billion, came from running online ads for scams and banned goods, according to a Thursday report from Reuters.
Those kinds of ads included promotions for “fraudulent e-commerce and investment schemes, illegal online casinos and the sale of banned medical products,” according to the Reuters report, which was based on internal company documents. Those documents showed the company’s attempts to measure the prevalence of fraudulent advertising on its apps like Facebook and Instagram.
Meta brought in more than $164.5 billion in overall sales for 2024. Last week, the company said that third-quarter sales rose 26% year-over-year to $51.24 billion and that it lifted the low end of its total expenses for the year by $2 billion as part of its massive investments into artificial intelligence.
The Reuters report cited a December 2024 document that showed how Meta each year generates roughly $7 billion in annualized sales from so-called “higher risk” scam ads, which are promotions that are clearly deceptive. Each day, Meta shows users an estimated 15 billion of these higher risk scam ads, the Reuters report said, citing a separate document.
Although some of the documents show that Meta aims to reduce the amount of bogus ads on its platform, the Reuters report also said that other documents suggest the company is concerned that its business projections could be impacted by any abrupt removal of the fraudulent promotions.
A Meta spokesperson said that the company “aggressively” addresses scam and fraud ads on its apps. The projections that 10% of the company’s 2024 ad sales came from bunk ads “was a rough and overly-inclusive estimate rather than a definitive or final figure; in fact, subsequent review revealed that many of these ads weren’t violating at all,” the spokesperson said in a statement.
“Unfortunately, the leaked documents present a selective view that distorts Meta’s approach to fraud and scams by focusing on our efforts to assess the scale of the challenge, not the full range of actions we have taken to address the problem,” the spokesperson said.
