Samsung Electronics Co., Ltd. saw its market capitalization breach the significant threshold of 1,000 trillion won (approximately $688 billion) for the first time during Wednesday's trading session. This milestone marks the first instance of a South Korean enterprise reaching such a valuation, driven by a sustained rally in the company's share price amid the global artificial intelligence frenzy.

According to data from the Korea Exchange, Samsung Electronics' shares closed at 169,100 won, a 0.96% increase from the previous session, pushing its market capitalization to 1,001 trillion won. During the day, the stock price climbed as high as 169,400 won, briefly giving the company a market value of around 1,002 trillion won.

Since its share price surpassed the 100,000 won mark on October 27th of last year, Samsung Electronics has maintained a record-breaking performance. This surge was initially fueled by a significant uptick in semiconductor demand, driven by massive global investments in AI infrastructure.

Industry observers anticipate that Samsung Electronics will continue to deliver robust performance in the future, with expectations for the company to further expand its market share in the premium High Bandwidth Memory (HBM) sector.

The company achieved record-breaking operating profit and sales in the fourth quarter of 2025. Its net profit for the entire previous year reached 45.2 trillion won, representing a substantial 31.2% increase compared to the year before.
