Samsung Reclaims Top Memory Spot in 4Q25

Samsung reclaimed the top spot in the memory market in 4Q25 with a revenue of KRW 37.1 trillion ($25.9 billion), according to Counterpoint Research. Simultaneously, SK Hynix set an industry record with a 58% operating profit margin.

SK hynix’s record margin serves as a powerful testament that memory semiconductors have evolved beyond simple commodities into indispensable, core components of the AI era. Strong sales of high-value-added products, such as HBM and server DRAM, coupled with rising prices for conventional DRAM, served as the primary growth drivers for both companies.

DRAM operating profit margins are on a steep upward trajectory. While the industry suffered negative margins in 2023 due to inventory gluts and collapsing prices, SK hynix spearheaded a sharp recovery as HBM3E shipments gained full momentum. By 2025, both Samsung and SK hynix were seeing a significant surge in profitability, bolstered by the skyrocketing prices of conventional memory. “2026 is projected to be a ‘Golden Era’ for the memory industry, as the mass production of HBM4 aligns with the maximization of profitability in conventional DRAM,” noted Jeongku Choi, Senior Analyst at Counterpoint Research.

The upward price trajectory is expected to persist for the foreseeable future. Following a surge of over 50% in 4Q25, memory prices are forecasted to rise by an additional 50% in the first quarter of this year. This sustained price rise is anticipated to impact all sectors of the electronics industry. “Consumer electronics, such as PCs, will be the most heavily affected. Products and brands with weaker price negotiation power are expected to face mounting pressure,” commented Tom Kang, Research Director at Counterpoint Research.
