That projection for demand is more than double the current global capacity for HBM or high-bandwidth memory, underscoring Stargate’s enormity and quickening global AI development, the SK group said. Shares in SK Hynix, the leader in HBM, surged 12% to its highest in more than two decades. Rival Samsung’s stock rose as much as 4.7% to a four-year peak, while Hynix-supplier Hanmi Semiconductor Co. leapt about 8%.
Samsung Electronics Co. and SK Hynix Inc. shares rose to their highest in years after South Korea’s largest companies forged initial agreements to supply chips to OpenAI’s Stargate project, reinforcing their lead in artificial intelligence memory.
OpenAI’s Sam Altman signed a letter of intent Wednesday to enlist the two firms in his data centre construction effort, a global undertaking that involves the sector’s biggest players from Nvidia Corp. to Oracle Corp. The US startup could need as many as 900,000 wafers per month as Stargate expands, the companies said.
