Samsung Hits $1 Trillion Market Cap on AI Chip Surge
CNBC reported Wednesday that Samsung Electronics crossed a Samsung $1 trillion market capitalization milestone after its shares jumped more than 10% in a single session, powered by surging artificial intelligence investment and a blowout earnings report.
The South Korean chipmaker becomes only the second Asian company to reach that threshold, joining Taiwan’s TSMC in the exclusive club.
Record Profits Fuel the Rally
The share surge followed Samsung’s strongest quarterly result on record. First-quarter operating profit climbed more than eightfold to 57.2 trillion Korean won, while revenue reached an all-time high of 133.9 trillion won. Notably, that single-quarter profit figure already exceeded Samsung’s entire full-year 2025 operating profit of 43.6 trillion won.
Analyst firm Morningstar attributed the gains in part to tight semiconductor supply constraints driving up chip prices, particularly across South Korea’s technology sector.
Apple Supply Report Adds Another Catalyst
An additional tailwind came from a Bloomberg report indicating that Apple has held preliminary discussions with Samsung and Intel about manufacturing chips for its devices inside the United States. The talks suggest Apple may be seeking to reduce its heavy dependence on TSMC as a sole advanced chip supplier. Investors read the news as a potential long-term revenue opportunity for Samsung’s foundry division.
Background: The HBM Race
Samsung’s rise to the $1 trillion mark did not come without friction. The company lost its early dominance in the high-bandwidth memory market to rival SK Hynix, which has been the preferred supplier of HBM chips to Nvidia. HBM technology stacks memory dies to deliver the extreme bandwidth required by large AI models running in data centers.
Samsung has been working to close that gap. In February, the company announced it had become the first firm globally to begin mass production of HBM4, the sixth generation of the technology, and had started shipments to undisclosed customers. HBM4 is expected to feature in Nvidia’s forthcoming Vera Rubin AI architecture, designed for next-generation data center workloads.
Kospi Breaks 7,000 for the First Time
The wider South Korean market also benefited from the chip euphoria. Shares of SK Hynix climbed more than 9% on the same session. That combined buying pressure lifted the benchmark Kospi index more than 5%, carrying it above the 7,000 level for the first time in its history. The milestone underscores how deeply South Korea’s equity market is tied to the global AI infrastructure build-out.
Samsung first briefly crossed the $1 trillion valuation threshold in late February, according to FactSet data, but Wednesday’s move cemented that status with considerably more momentum behind it.
