SEOUL (AFP) : South Korean tech giant Samsung Electronics posted record quarterly profits Thursday, riding massive market demand for the memory chips that power artificial intelligence. The dazzling earnings came a day after a key competitor, South Korean chip giant SK hynix, said operating profit had doubled last year to a record high, also buoyed by the AI boom. Samsung said Thursday it expects “AI and server demand to continue increasing, leading to more opportunities for structural growth”. SK hynix announced Wednesday that its operating profit had doubled last year to a record 47.2 trillion won. But Nvidia has reportedly allocated around 70 percent of its HBM4 demand to SK hynix for 2026, up from the market’s previous estimate of 50 percent.
