SK Hynix Inc.’s stock climbed as much as 5.9% on Friday to a record after the company announced it had completed development of HBM4, the next generation of high-bandwidth memory crucial for artificial intelligence work. The Seoul-traded chipmaker, whose shares are up roughly 90% over the past year, is now worth close to $170 billion. The company’s stock was on an eight-day winning streak ahead of the announcement, as bullish AI sentiment lifted key supply chain players. SK Hynix is the go-to HBM provider for Nvidia Corp., surpassing much bigger rival Samsung Electronics Co. to secure a lead in this advanced technology. SK Hynix said on Friday that it’s now ready for mass production with HBM4. The development underscores the company’s effort to solidify its leadership in a rapidly growing and highly lucrative market. The company has benefited from being first to market, having shipped the world’s first 12-layer HBM4 samples to customers early this year, ahead of competitors like Micron Technology Inc. and Samsung.
