South Korea's SK Hynix forecast sales of its high-end semiconductors used in generative artificial intelligence chipsets would double this year after reporting a record quarterly profit that surpassed its bigger rival Samsung.

SK hynix is estimated to have surpassed Samsung Electronics' Device Solutions (DS·semiconductor) division operating profit, recording the largest results ever last year. Securities firms projected that SK hynix's operating profit will further increase this year, not lagging behind Samsung Electronics' entire institutional sector.

SK Hynix Inc., a major supplier of memory chips, has announced record quarterly earnings. However, investors have reacted cautiously. Concerns about smartphone demand and future AI spending have tempered enthusiasm.
