Shares of Samsung Electronics jumped over 15 per cent on Wednesday, lifting the chipmaker’s market value above $1 trillion as investors continued to rush into artificial intelligence-related stocks.

Samsung becomes the second Asian firm to surpass the $1 trillion valuation milestone, following TSMC.

According to FactSet data, the company first reached that level on February 26.

The stock hit a record high during the session and is tracking its biggest single-day gain on record, FactSet data also showed.

The rally came after Samsung Electronics reported record first-quarter earnings last week. Operating profit surged more than eightfold to 57.2 trillion won, while revenue rose to an all-time high of 133.9 trillion won.

The company’s first-quarter operating profit also exceeded its full-year 2025 profit of 43.6 trillion won.

Investor sentiment was further lifted by a Bloomberg report that Apple has held early-stage talks with Samsung and Intel on potentially manufacturing chips for its devices in the United States, a move that could reduce its reliance on long-time supplier TSMC.

Sales of high-bandwidth memory chips have strengthened Samsung’s profitability, though the company still faces stiff competition after losing its early lead in the HBM market to rival SK Hynix.

Samsung has been working to close the gap with SK Hynix in the rapidly expanding AI memory segment.

In February, the company said it had become the first in the world to begin mass production of HBM4 chips and had started shipments to undisclosed customers.
