SK Hynix shares surged more than 7% to a record high during trading in Seoul, driven by renewed investor confidence in artificial intelligence demand after Intel’s latest earnings report painted a bullish picture for the sector.
The move helped drag South Korea’s benchmark KOSPI index past the 8,000-point threshold.
What’s driving the rally
Intel’s earnings report acted as the catalyst, reigniting expectations that demand for AI infrastructure remains not just intact but accelerating. SK Hynix, as the primary supplier of high-bandwidth memory (HBM) chips for Nvidia’s AI accelerators, sits at the center of that supply chain.
The stock’s performance on the day outpaced gains made by Samsung Electronics, its crosstown rival. Samsung has been trying to close the gap in HBM production, but SK Hynix continues to hold the supplier relationship that matters most: the one with Nvidia.
