In a groundbreaking achievement for the technology industry, SK Hynix has surpassed Samsung Electronics in operating profit for the first time, setting a record operating profit of 47.2 trillion won in 2025. This monumental accomplishment positions SK Hynix as a leader in the high-bandwidth memory (HBM) market, a critical component for AI processors and servers.
SK Hynix’s Strategic Dominance in High-Bandwidth Memory
HBM, or high-bandwidth memory, has become indispensable for advanced AI applications. Whether supporting Nvidia’s cutting-edge AI technologies or enabling powerful server performance, these memory solutions are in greater demand than ever. This surge in demand has cemented SK Hynix’s leadership in the market.
According to analysts, SK Hynix’s unparalleled quality and consistent supply of high-bandwidth memory are key drivers of its dominance, helping the company maintain its edge over competitors like Samsung and Micron. According to MS Hwang of Counterpoint Research, SK Hynix has played a pivotal role in supporting the global AI infrastructure boom.
How Samsung is Responding
While SK Hynix holds a commanding lead, Samsung is quickly closing the gap with the launch of its advanced HBM4 chips. These next-generation chips are expected to intensify competition in the AI memory sector as demand continues to soar across industries.
However, SK Hynix isn’t standing still. The company recently announced a $10 billion investment plan to launch a U.S.-based entity focused on accelerating artificial intelligence innovation. Tentatively named the “AI Company,” the initiative outlines their strategic intent to expand globally and lead in the AI-driven memory and technology markets. To achieve this, SK Hynix is restructuring its California-based subsidiary, Solidigm, separating AI and SSD operations for streamlined efficiency.
What This Means for the AI Industry
SK Hynix’s focus on HBM and memory solutions underlines the growing importance of specialized components in the era of AI. From autonomous vehicles to advanced data centers, memory technology like HBM is vital in supporting the performance demands of next-generation AI systems.
