Amid a relentless surge in demand for AI-linked semiconductors, South Korean chip giant SK Hynix has achieved a $1 trillion market capitalization, with its shares soaring by approximately 250% this year. This milestone follows domestic rival Samsung Electronics’ recent entry into the trillion-dollar club, highlighting the growing significance of the nation’s chipmakers in the global AI supply chain, especially as a key supplier to Nvidia.
South Korean semiconductor giant SK Hynix has soared past a $1 trillion market capitalization, with its shares rocketing by as much as 11% on Wednesday. This dramatic surge underscores investors' ravenous appetite for artificial intelligence (AI)-linked semiconductor stocks, fueling a remarkable run for the company.

The rally extends a scorching performance that has seen SK Hynix shares skyrocket approximately 250% since the beginning of the year. This impressive growth is largely attributed to the exploding demand for high-bandwidth memory chips, which are crucial components in advanced AI servers and accelerators.
SK Hynix has cemented its role as a pivotal supplier to AI chip behemoth Nvidia, placing it squarely at the heart of the burgeoning global AI supply chain.
This valuation milestone arrives just weeks after its domestic rival, Samsung Electronics, also crossed the $1 trillion market capitalization threshold. Samsung's shares also saw a significant boost, adding over 6% on Wednesday.

Together, these two chipmaking powerhouses account for more than 40% of South Korea's benchmark Kospi index. This concentration highlights how intimately the index's performance is now tied to the global demand for AI-related semiconductors and memory chips. Data from LSEG indicates the Kospi index has nearly doubled since the start of the year.
However, analysts have voiced concerns that this high concentration could amplify market volatility, leaving the benchmark more vulnerable to potential risks such as supply chain disruptions and a slowdown in global data center investment.
Despite these warnings, Peter Kim, a global investment strategist at KB Financial Group, believes SK Hynix's rally may still have considerable room for growth. He points out that earnings upgrades are currently outpacing even the stock's already impressive gains.
Kim emphasized that the "fundamentals and valuations of the two twin towers… are still very much intact," referring to SK Hynix and Samsung Electronics. He added that SK Hynix's valuation has become "cheaper" as analysts have revised their earnings forecasts upwards at a faster rate than its share prices have increased.
