Samsung Breaks the One Trillion Dollar Barrier: Stocks Soar Thanks to AI

The semiconductor sector is going through an unprecedented phase of euphoria, with Samsung Electronics recently securing its place in the exclusive club of companies with a market capitalization exceeding one trillion dollars.

The decisive push came from an impressive stock rally, with shares of the South Korean giant rising by over 15% in a single session, marking the highest daily increase ever recorded in the company's history. This leap allowed Samsung to become the second Asian entity, after TSMC, to surpass this psychological and financial threshold, simultaneously propelling the Kospi index past the historic 7,000-point mark.

The financial fundamentals justify investors' enthusiasm. In the first quarter of 2026, Samsung reported an operating profit of 57.2 trillion won, a figure that not only represents an increase of more than eight times compared to the previous year but also exceeds the entire operating profit generated during all of 2025 (43.6 trillion won). Revenue has also reached unprecedented heights, standing at 133.9 trillion won.

Samsung Exceeds One Trillion Dollars: AI Semiconductors Rewrite Records

The engine of this growth is undoubtedly linked to the demand for high-bandwidth memory (HBM). After chasing competitor SK Hynix in the HBM3e segment, Samsung has accelerated its efforts by announcing the start of mass production of HBM4 chips as early as February 2026. These sixth-generation components are set to become the cornerstone of Nvidia's upcoming Vera Rubin architecture, designed to handle next-generation AI workloads in global data centers.

Although SK Hynix still holds a dominant market share in the HBM sector (estimated at 55% compared to Samsung's 25%), analysts observe that the technological gap is closing rapidly. Feedback from partners on Samsung's HBM4 samples is extremely positive, indicating renewed competitiveness in the advanced memory sector. Additionally, the profitability of conventional DRAM memories has recently surpassed that of HBM, a dynamic that benefits Samsung's diversified production structure.

In addition to direct results in memory sales, market excitement has been fueled by rumors regarding the potential diversification of Apple's supply chain. According to internal sources, Cupertino has initiated exploratory talks with Samsung and Intel for the production of chips for its devices on U.S. soil. If confirmed, this move would reduce Apple's dependence on TSMC, opening up enormous opportunities for Samsung as the primary foundry for A-series and M-series processors.

The current shortage of DRAM and NAND chips, caused by demand for storage and bandwidth exceeding installed production capacity, suggests that the positive cycle for Samsung is set to last. As activating new plants typically takes two to three years, the supply constraint will keep prices high and operating margins solid for at least the next eight quarters, consolidating Samsung's position as a cornerstone of global technological infrastructure.
