Samsung Electronics has surpassed a $1 trillion market valuation for the first time, driven by a powerful rally in semiconductor stocks linked to surging global demand for artificial intelligence infrastructure. The milestone was reached in early May 2026 after the company’s shares jumped more than 12% in Seoul trading, as reported by Reuters.
The rally comes amid a broader surge in AI-related equities, with global chipmakers benefiting from increased spending on data centres and high-performance computing. Samsung, the world’s largest memory chip producer, has seen strong demand for advanced memory products such as high-bandwidth memory used in AI systems, pushing its valuation above 1,500 trillion won (about $1.03 trillion), as highlighted by Reuters.
The stock surge at times exceeding 15% has also lifted South Korea’s benchmark KOSPI index to record highs above 7,000 points, reflecting a broader investor shift toward semiconductor-driven growth. Analysts attribute the momentum to global AI investment cycles, strong earnings performance, and renewed foreign inflows into Asian tech markets, as noted by Business Insider.
Samsung’s entry into the trillion-dollar club makes it only the second Asian company after Taiwan Semiconductor Manufacturing Company to reach the milestone, underscoring the strategic importance of chips in the global economy. Analysts say the rally signals a structural shift, with AI demand now a primary driver of market value and long-term growth across the semiconductor industry.
