AI boom puts SK Hynix on the cusp $1 trillion market value

SEOUL, May 14 (Reuters) – SK Hynix is on the verge of topping a $1 trillion market value, just weeks after Samsung Electronics crossed the milestone, as strong demand for artificial intelligence ​places South Korea at the heart of Asia’s AI boom.

SK ‌Hynix shares have risen more than 200% this year, after rising an eye-watering 274% in 2025, driven by AI-related demand for both conventional memory chips and high-bandwidth memory (HBM) chips used in AI servers.

If SK Hynix joins Samsung above the trillion-dollar ‌threshold, ​South Korea would become the first country ⁠outside the United States to ⁠have more than one trillion-dollar company.

“The market is running on FOMO sentiments, especially on AI-related names in Japan and Korea,” said Fabien Yip, market analyst at IG in Sydney.

Samsung became Korea’s first ​trillion-dollar company earlier this month, although Taiwan’s TSMC remains Asia’s biggest company by market value at over $1.83 trillion.

The three chipmakers and their ⁠record earnings have put the spotlight ⁠on their critical role in the global AI supply ​chain.

South Korea’s benchmark KOSPI index has climbed in near-vertical fashion, hitting record ​highs as foreign investors both big and small have poured ‌into chipmakers.

The index is up more than 86% this year, after soaring 75% in 2025 in its strongest annual performance since 1999. Since the start of 2025, the KOSPI has been the best-performing major stock ⁠market in the world.

SK Hynix, worth less than $100 billion 16 months ago, is now closing in on the market values of retail giant Walmart ⁠and Berkshire Hathaway, the ‌investment vehicle of the legendary investor Warren Buffett.

On ⁠Thursday, SK Hynix shares edged down 0.48% while ​Samsung rose ‌more than 3% to a record high, in ​a broader ⁠market that was up 0.9% – not far from the record high it reached earlier this week. SK Hynix’s market cap was roughly at $948 billion, based on Wednesday’s price and exchange rate.
