Samsung hits $1 trillion valuation on AI chip boom

Samsung Electronics crossed into trillion-dollar territory in May 2026, joining an exclusive club of Asian companies that have reached that valuation milestone. The company's ascent was driven by a single, powerful force: the world's insatiable appetite for the memory chips that power artificial intelligence systems. Over the previous twelve months, Samsung's share price had more than quadrupled. On May 6 alone, an 11 to 12 percent jump pushed the company past the trillion-dollar mark, making it only the second Asian firm after Taiwan Semiconductor Manufacturing to achieve this distinction.

Samsung's position in the global chip supply chain explains much of this momentum. The company is the world's largest memory chipmaker, and alongside South Korean rival SK Hynix, it supplies the critical components that AI infrastructure demands: high-bandwidth memory, or HBM, used in servers and data centers; dynamic random access memory, or DRAM; and NAND chips. These are not luxury goods or niche products. They are the foundational materials upon which the entire AI buildout rests. During the company's earnings call, Kim Jae-june, executive vice president of Samsung's memory division, outlined the scale of the shift. HBM4 sales, he said, would account for more than half of total HBM revenue starting in the third quarter, and would represent the majority for the full year. The division expected HBM revenue to grow more than threefold compared to the previous year.

What had once been a cyclical business—memory chips rising and falling with the technology cycle—had transformed into something different. Bloomberg reporting noted that AI infrastructure demand had shifted the market toward structural, long-term growth. This was not a temporary spike. Customers were already securing inventory for the following year, bracing against potential shortages. The demand, Kim noted, continued to outpace supply.

The financial results bore this out. Samsung's semiconductor division posted record profits in the March quarter, with earnings rising 48-fold year-on-year. The division generated 53.7 trillion won, approximately $36.15 billion, out of the company's total operating profit of 57.2 trillion won, or about $39.3 billion. Semiconductors now accounted for the overwhelming majority of Samsung's earnings. Industry analysts, citing Bloomberg data, expected this trend to persist. Tight supply conditions would likely sustain elevated chip prices through 2027.

Yet the picture was not uniformly bright across Samsung's operations. The mobile and network division saw profit collapse by 35 percent in the first quarter, dropping to 2.8 trillion won, roughly $1.9 billion. The display division fared little better, recording a 20 percent decline in operating profit to 400 billion won, or about $270 million. Rising costs were squeezing these businesses even as semiconductors soared. Labour tensions had also emerged, with workers demanding higher compensation as the company's earnings surged.

Despite these headwinds in other divisions, market expectations remained bullish. Samsung was trading at around 5.3 times forward earnings, a valuation that left room for growth. Analysts projected the stock would gain roughly 30 percent over the next twelve months, buoyed by the continued tightness in memory markets and the structural demand for AI chips that showed no signs of abating. For Samsung, the trillion-dollar milestone was not a destination but a waypoint—a marker of how thoroughly the company's fortunes had become bound to the infrastructure race that was reshaping global technology.
