--- title: "SK Hynix Becomes Korea’s Most Valuable Company in AI Era" date: 2026-06-22 author: "Kelvin Scott" featured_image: "https://coinlaw.io/wp-content/uploads/2026/06/sk-hynix-becomes-korea-s-most-valuable-company.jpg" categories: - name: "Investments" url: "/investments.md" tags: - name: "News" url: "/tag/news.md" --- # SK Hynix Becomes Korea’s Most Valuable Company in AI Era SK Hynix has overtaken Samsung Electronics in market value for the first time in 25 years, highlighting how the artificial intelligence boom has reshaped the global semiconductor industry. ## Key Takeaways - SK Hynix briefly surpassed Samsung Electronics to become South Korea’s most valuable listed company. - The company’s market capitalization reached about 2,082.5 trillion won ($1.35 trillion), narrowly ahead of Samsung. - Strong demand for high bandwidth memory (HBM) chips used in AI systems has fueled SK Hynix’s rapid growth. - The milestone marks a remarkable turnaround for a company that nearly collapsed under debt more than two decades ago. ## What Happened? **SK Hynix overtook Samsung Electronics on June 22**, ending Samsung’s uninterrupted position as South Korea’s most valuable listed company, a title it had held since 2000. The achievement reflects the growing importance of AI infrastructure and the critical role SK Hynix plays in supplying advanced memory chips used in artificial intelligence systems. The company’s rise has been driven by soaring demand for HBM chips, which are widely used in AI servers and accelerators developed by companies such as Nvidia and Google. > 🔴 SK Hynix overtakes Samsung as South Korea’s most valuable listed company > > SK Hynix’s market capitalization reached 2,082.5 trillion won (~$1.35 trillion), surpassing Samsung Electronics, which had previously held the top position. > • SK Hynix stock surged 1,400% over the past… [pic.twitter.com/USc5U3NN9P](https://t.co/USc5U3NN9P) > > — NewsTongue (@NewsTongueX) [June 22, 2026](https://x.com/NewsTongueX/status/2068941666577158450?ref_src=twsrc%5Etfw) ## AI Memory Boom Powers SK Hynix Higher Shares of **SK Hynix** surged more than 5% on Monday, pushing the company’s market capitalization to approximately **2,082.5 trillion won**, or about **$1.35 trillion**. Samsung Electronics stood close behind with a market value of roughly **2,081.3 trillion won** based on common shares. ![Sk Hynix Stock Price 22nd June](https://coinlaw.io/wp-content/uploads/2026/06/sk-hynix-stock-price-22nd-june.png)Image Credit – [Google Finance](https://www.google.com/finance/quote/000660:KRX?sa=X&ved=2ahUKEwjMo-e33JqVAxWIUGwGHfFTKKEQ3ecFKAR6BAg3EAU) The achievement underscores how AI has transformed the semiconductor sector. What were once viewed largely as commodity memory products have become essential components of modern AI infrastructure. SK Hynix has emerged as the dominant supplier of **high bandwidth memory**, a specialized chip technology that enables AI processors to handle enormous amounts of data at high speeds. The company currently controls about **61% of the global HBM market**, significantly ahead of rivals Samsung and Micron. Kim Sunwoo, a senior analyst at Meritz Securities said: “ The emergence of customised AI memory fundamentally changed the industry’s economics and allowed SK Hynix to establish itself as the market leader. Kim SunwooSenior analyst – Meritz Securities ## A Historic Reversal of Fortunes The milestone represents one of the most dramatic corporate turnarounds in South Korean history. In 2002, the company, then known as **Hynix Semiconductor**, was struggling under heavy debt and came close to being sold to Micron. The deal eventually fell apart, and the company spent years under creditor control. Its shares plunged to just **135 won in 2003**, leading many investors to view it as a penny stock. The company’s fortunes continued to fluctuate with the cyclical memory chip industry. As recently as 2023, a sharp downturn in memory prices contributed to a yearly operating loss of **7.73 trillion won**. However, the rise of artificial intelligence dramatically changed its trajectory. Increased spending by major technology companies including Microsoft, Google, and Meta fueled demand for advanced memory solutions. By 2024, SK Hynix reported a record annual operating profit of **23.5 trillion won**, reflecting the industry’s rapid recovery. ## Strategic Bet on HBM Pays Off Industry analysts credit SK Hynix’s success to its decision to continue investing in HBM technology during a difficult period for the memory market. Unlike conventional memory products, [HBM chips are tightly integrated with AI processors](https://coinlaw.io/nvidia-sk-hynix-ai-memory-supply-deal/) and offer faster performance while consuming less power. The technology is difficult to manufacture and qualify, creating higher barriers to entry and stronger pricing power for suppliers. SK Group Chairman Chey Tae-won explained the vision behind acquiring Hynix years ago. “ What I really wanted to accomplish when we acquired Hynix was to transform it from a commodity memory producer into a mainstream semiconductor company whose products are indispensable. In the past, it did not matter whether memory came from Hynix, Samsung or Micron. They were interchangeable commodity products. HBM is different. If SK Hynix’s HBM is replaced with another product, the AI system may not function properly. What used to be a peripheral component has become a core component. Chey Tae-wonChairman – SK Group ## Competition With Samsung Continues Despite losing the top spot based on common shares, [Samsung](https://coinlaw.io/samsung-pay-statistics/) argued that its preferred shares should be included when calculating market value. Including those shares would place Samsung’s valuation above SK Hynix. The competition between the two chipmakers is far from over. Samsung remains the world’s largest DRAM producer by manufacturing scale. However, analysts expect SK Hynix to continue expanding production capacity and narrowing the gap over the coming years. Reports have also indicated that SK Hynix is considering a future U.S. listing, potentially on the Nasdaq, a move that could broaden its investor base and strengthen its global profile. ## CoinLaw’s Takeaway In my experience, this milestone is about much more than a **temporary stock market ranking**. It shows how quickly the AI revolution is changing the technology landscape. I found the most important takeaway to be that specialized AI infrastructure is now creating winners that would have been difficult to imagine just a few years ago. SK Hynix’s journey from a debt burdened chipmaker on the brink of collapse to the most valuable company in South Korea highlights how strategic investments in emerging technologies can completely transform a business. As AI adoption accelerates, companies providing the critical components behind that growth are likely to remain at the center of investor attention.
