SK Hynix Shares Surge on AI Data Center Spending Optimism

Shares of SK Hynix jumped as much as 12% on Monday, extending recent gains as investor sentiment strengthened following robust earnings from major U.S. technology firms.

The rally was largely driven by foreign buying, with investors responding positively to signals from leading American tech companies that they plan to sustain heavy investment in artificial intelligence infrastructure, particularly data centers. These spending commitments are expected to fuel continued demand for high-performance memory chips, a core business area for SK Hynix.

The chipmaker’s strong performance contrasted with that of its larger rival, Samsung Electronics, whose shares have faced pressure amid concerns over a potential labor strike. Unionized workers at Samsung are reportedly seeking a larger share of the company’s AI-driven profits, adding uncertainty to its near-term outlook.

SK Hynix’s gains underscore the broader market momentum tied to the AI boom, as semiconductor firms positioned within the data center supply chain continue to benefit from rising capital expenditure by global technology leaders.
