Samsung Becomes First Korean Company to Top 1,000 Trillion Won in Market Value

An AI-driven surge in high-performance memory demand is lifting profit expectations.

Overview

  • Shares closed at 169,100 won after an intraday high of 169,400 won, putting Samsung’s market capitalization at about 1,001 trillion won, according to the Korea Exchange.
  • The rally helped send the Kospi to a record close of 5,371.10, with Samsung accounting for 22.56% of the index’s total market value.
  • Samsung said it will start mass production of next‑generation HBM4 this month, reinforcing expectations for gains in high‑bandwidth memory used in AI servers.
  • The company posted record quarterly operating profit in Q4 2025 and reported full‑year 2025 net income of 45.2 trillion won alongside strong revenue and operating profit growth.
  • Analysts have raised targets and forecasts, with some projecting operating profit could reach as high as 170 trillion won this year if the memory upcycle persists; S&P Global Ratings said stronger chip demand should bolster credit metrics.
