DRAM Market Share by Revenue, Q3 2024 – Q3 2025
While SK hynix ceded the top spot in the overall memory market to Samsung Electronics this quarter, it continued to lead the DRAM segment, supported by robust demand for both HBM and general DRAM. In the HBM market, SK hynix held a dominant 58% share, maintaining clear leadership. HBM accounted for 40% of SK hynix’s total DRAM sales in Q3. The company is also expected to deliver HBM4 products smoothly in line with customer requirements. In the general-purpose DRAM segment, stronger demand and rising prices contributed to the company’s solid performance.
“SK hynix is expected to continue its strong performance in the fourth quarter as AI memory demand remains high. The company is responding well to evolving customer requirements in HBM4 development and remains a leader in yield performance,” said Jeongku Choi, Research Analyst at Counterpoint Research.
