Samsung Electronics

South Korean semiconductor giants SK Hynix and Samsung Electronics surged on Friday, mirroring a U.S. tech rally. Strong earnings from Amazon and Microsoft fueled investor confidence in AI infrastructure spending. SK Hynix and Samsung saw significant stock price increases, as did Japanese chip manufacturers. This rally marks a turnaround after earlier market uncertainty, with strong cloud growth from tech leaders reinforcing the robust demand for AI-related technologies and infrastructure.

Samsung and SK Hynix shares plunged over 7% and 10% respectively, mirroring a Nasdaq downturn and impacting the Kospi index. This broad tech sector selloff, amplified by Micron’s decline, signals a market recalibration. Investors are scrutinizing AI monetization and fundamentals, moving from speculative growth to a more profit-driven approach. Samsung’s focus on “mobile agentic AI” aims to boost device intelligence and revenue.

Samsung Electronics is expanding its use of OpenAI’s ChatGPT Enterprise and Codex to all employees, including the global Device eXperience division. This move aims to boost innovation and efficiency across various functions like software development, marketing, and product ideation, enhancing tasks from information retrieval to code debugging. The initiative signifies a secure integration of generative AI, contrasting with previous data security concerns, and aligns with Samsung’s role as a strategic memory partner for OpenAI’s infrastructure.

SK Hynix has surpassed Samsung Electronics in operating profit for 2025, a first for the company. This achievement is driven by SK Hynix’s dominant position in high-bandwidth memory (HBM) chips, essential for AI processors. While Samsung is diversifying, SK Hynix’s specialized focus on memory, particularly HBM, has proven highly successful amid the AI infrastructure boom. Despite increasing competition from Samsung and Micron, SK Hynix is expected to maintain its leadership in the critical HBM market.

Samsung Electronics reported a robust semiconductor recovery in Q3 2025 with operating profit of KRW 12.2 trillion (US$8.6 billion), driven by its Device Solutions division and record-high memory revenue fueled by HBM3E and server SSD sales. This rebound, ending four quarters of decline, stems from strategic shifts, improved market dynamics, and growing AI chip demand. Samsung is mass-producing HBM3E and sampling HBM4, aiming for continued growth in the AI infrastructure market. Foundry business also improved, while System LSI faced challenges.

Samsung Electronics reported a strong Q3 rebound driven by surging demand for memory chips used in AI applications. Operating profit increased 32.9% year-over-year, exceeding analyst expectations. The chip business saw a tenfold increase in operating profit compared to the previous quarter. Samsung regained its position as the leading memory market player and anticipates continued growth in AI chip demand, focusing on mass production of HBM4 in 2026. The Mobile eXperience division also demonstrated positive growth fueled by flagship smartphone sales.

Reports suggest NVIDIA has secured a deal with Samsung for its 12-layer stacked HBM3E memory, potentially for use in liquid-cooled server systems. The initial order is rumored to be 30,000-50,000 units. Samsung has neither confirmed nor denied the agreement. While previous validation claims proved premature, Wall Street analysts are optimistic that Samsung will complete certification by the end of August and begin shipments to NVIDIA in Q4. Samsung aims to reduce HBM3E production costs and expects increased HBM profitability.

SK Hynix surpassed Samsung Electronics in operating profit in 2024, achieving 21.33 trillion won, driven by a strong performance in the memory chip market. South Korea’s 1,000 major listed companies also saw record profits, with a 92.7% increase from 2023. While Samsung had significantly higher revenue, SK Hynix’s operating profit margin was much higher. The CXO Institute predicts SK Hynix to maintain its lead in 2025.
