Key Takeaways
- Samsung Electronics shares rallied over 15% during local market hours, elevating the company’s valuation beyond $1 trillion — becoming just the second Asian tech firm after TSMC to achieve this milestone.
- The impressive surge came after the company posted exceptional first-quarter results, with operating profit climbing more than eightfold to reach ₩57.2 trillion ($39 billion).
- Growing artificial intelligence infrastructure requirements for high-bandwidth memory (HBM) chips combined with constrained DRAM and NAND supply are fueling momentum.
- Market excitement intensified following Bloomberg’s report that Apple has initiated preliminary discussions with Samsung and Intel regarding potential U.S.-based chip manufacturing.
- Competitor SK Hynix experienced gains exceeding 10%, contributing to South Korea’s Kospi index breaking through the 7,000 threshold for the first time in history.
Samsung Electronics is experiencing what could become its largest single-session percentage increase ever, driven by outstanding first-quarter financial results and accelerating AI-related semiconductor demand.
Shares skyrocketed more than 15% during Wednesday’s trading session in Seoul, propelling the company’s market capitalization past the symbolic $1 trillion milestone. This achievement places Samsung as only the second East Asian technology company to reach this valuation level, following Taiwan Semiconductor Manufacturing Company.
Samsung Electronics Co., Ltd., SMSD.L
The dramatic price movement follows Samsung’s announcement last week revealing first-quarter operating profit reached ₩57.2 trillion — representing more than an eightfold increase compared to the same period last year. The company also reported record quarterly revenue of ₩133.9 trillion. Remarkably, Samsung’s Q1 profit alone exceeded its entire 2025 full-year profit of ₩43.6 trillion.
Additional momentum came from a Bloomberg report indicating Apple has engaged in preliminary conversations with both Samsung and Intel regarding potential chip production within U.S. borders. Such a development would represent a significant strategic pivot from Apple’s historical dependence on TSMC for semiconductor manufacturing.
SK Hynix, Samsung’s primary competitor in memory chip production, also experienced gains surpassing 10% on Wednesday. These combined rallies pushed South Korea’s flagship Kospi index past 7,000 points for the first time — establishing an unprecedented benchmark for the market.
Memory Supply Constraints Created by AI Expansion
Morningstar analyst Yu Jing Jie characterized the situation clearly: current market conditions reflect an acute shortage of both DRAM and NAND chips, largely attributable to the substantial memory requirements of artificial intelligence systems. Since new semiconductor production facilities typically require two to three years from groundbreaking to operation, supply constraints are expected to persist.
This supply-demand imbalance benefits Samsung’s profitability outlook. Rolf Bulk from The Futurum Group indicated that elevated memory pricing and robust earnings performance should continue even as additional manufacturing capacity comes online industry-wide throughout the coming years.
Client response to Samsung’s newest HBM4 chip technology has reportedly been favorable, according to Bulk. HBM4 represents the sixth and latest iteration of high-bandwidth memory technology and is anticipated to serve as a crucial component in Nvidia’s forthcoming Vera Rubin AI platform.
Samsung announced in February that it had become the industry’s first manufacturer to commence mass production of HBM4 chips, with initial shipments already reaching undisclosed clients.
Competitive Landscape: Samsung vs. SK Hynix
SK Hynix currently maintains market leadership in the HBM segment with approximately 55% market share. Samsung commands roughly 25% of the market. However, Bulk noted that investors have become less concerned about this competitive gap recently, as conventional DRAM products have begun generating higher profit margins than HBM chips.
Broader semiconductor sector strength was evident elsewhere, with Micron advancing 11%, AMD climbing more than 16% in extended trading following impressive Q1 results, and Intel gaining nearly 13%.
Chaiwon Lee, analyst at Life Asset Management, observed that Samsung currently trades at approximately six times forward 12-month earnings — substantially below TSMC’s roughly 25 times multiple and Micron’s approximately 10 times valuation. While acknowledging risks including intensifying Chinese competition and potential moderation in AI demand, Lee suggested the valuation discount indicates upside potential.
According to FactSet data, Samsung’s stock was approaching an all-time high as of Wednesday’s trading session.
