Samsung hits $688b market cap, a first for South Korea

Samsung Electronics’ market capitalization exceeded 1,000 trillion won (US$688 billion) on February 4, the first South Korean company to reach this level, as its shares rose amid increased global interest in AI and chip demand.

The company’s shares closed at 169,100 won (US$116.13), up 0.96 percent, according to the Korea Exchange.

The company reported record operating profit in Q4 2025, and for the full year, it posted a net income of 45.2 trillion won (US$31.04 billion), a 31.2% increase from the previous year.

Industry analysts expect Samsung to sustain its performance, particularly in expanding its high bandwidth memory (HBM) sector.

🧠 Food for thought

Implications, context, and why it matters.

Samsung’s record profit masks its underdog status in the AI memory race

Samsung booked record profit, yet SK Hynix still earned more full-year operating profit in 2025 for the first time, at 47.2 trillion won versus Samsung’s 43.6 trillion won 1.
SK Hynix leads in High Bandwidth Memory (HBM), a critical component for AI accelerators (specialized chips used to train and run AI models), with Counterpoint putting its Q3 2025 revenue share at 57% versus Samsung’s 22% 1.
Samsung’s share rise leans on a comeback story. Some versions cite earlier trouble qualifying HBM3E with Nvidia, though the source here does not back the timing details 2.
A Reuters-cited report says Samsung could become the first to ship next-generation HBM4 memory chips to Nvidia, which may help it close the gap with SK Hynix 3.

The AI memory boom is creating a structural shortage that could reshape the electronics industry

Commentators call the surge a “structural” change in memory demand rather than a normal cycle, though this framing reads as opinion in the provided material 4.
Memory makers are steering output toward higher-priced AI and server products, including HBM and server DRAM such as DDR5, which tightens supply elsewhere 5.
That shift may push up memory costs for smartphones, PCs, and other consumer devices. Stronger claims about pressure on low-margin brands need clear attribution to analysts or commentators 5.
Samsung says its available HBM capacity for 2026 is already sold out, and it expects HBM sales to more than triple year over year in 2026 6.
