Shares of Samsung Electronics experienced a remarkable surge of over 10% on Wednesday, catapulting the South Korean semiconductor powerhouse's market capitalization past the $1 trillion mark. This significant valuation milestone reflects investors' continued enthusiasm for stocks deeply entrenched in the burgeoning artificial intelligence sector.
Samsung now joins TSMC as only the second Asian company to achieve a $1 trillion market cap. According to FactSet data, the company initially crossed this impressive threshold on February 26th earlier this year.
This latest rally follows Samsung Electronics' stellar first-quarter earnings report released just last week. The company announced an extraordinary eightfold increase in operating profit, reaching 57.2 trillion won, alongside record revenue of 133.9 trillion Korean won. Notably, Samsung's first-quarter operating profit alone surpassed its full-year profit for 2025, which stood at 43.6 trillion won, underscoring its rapid financial acceleration.
Further boosting investor confidence was a recent Bloomberg report indicating that Apple has engaged in exploratory discussions with both Samsung and Intel regarding the potential for manufacturing chips for Apple devices in the United States. This strategic move could signal a diversification away from Apple's long-standing primary supplier, TSMC.
The widespread AI-driven market optimism also benefited other South Korean chipmakers, with shares of industry giant SK Hynix jumping over 9%. This collective upward movement among semiconductor stocks was a key factor in pushing the benchmark Kospi index more than 5% higher, enabling it to breach the 7,000-point level for the first time in its history.
While the robust sales of high-bandwidth memory (HBM) chips have been a significant contributor to Samsung's improved profitability, the company continues to navigate an intensely competitive HBM market. Samsung is actively working to regain its early advantage, which it had previously lost to rival SK Hynix. In a crucial development aimed at closing this gap in the fast-growing AI memory segment, Samsung announced in February that it had become the first company globally to commence mass production of HBM4 chips, the sixth and latest generation of this advanced memory technology, and had begun deliveries to undisclosed customers. These cutting-edge HBM4 chips are anticipated to play a pivotal role in Nvidia's upcoming Vera Rubin AI architecture, designed to power advanced AI workloads in data centers.
Morningstar analysts noted that strong demand fueled by AI infrastructure spending, combined with tight supply due to capacity constraints, has led to increased prices for semiconductor chips and other critical input costs, particularly impacting the market in South Korea.
