Samsung Regains HBM Market Share Lead
Samsung's HBM business regained momentum in Q3 2025 as market share reached 22%, surpassing Micron but trailing SK hynix, Counterpoint Research and Chosun Biz reported. The turnaround follows internal policy and development changes alongside reported customer wins from AMD (HBM3E) and NVIDIA (HBM3E/HBM4), plus HBM4 products claiming industry-leading pin speeds and planned competitive pricing. That positions Samsung to strengthen presence as HBM4 products mainstream in early 2026.
Key Points
- 1Reports show Samsung's HBM market share rose to 22% in Q3 2025.
- 2Internal process improvements and wins with AMD and NVIDIA restored competitiveness and product performance.
- 3Positions Samsung to secure larger HBM4 supply contracts as products mainstream in 2026.
Scoring Rationale
Credible, industry-wide customer wins and product momentum drive high impact, limited by incremental hardware evolution rather than paradigm shift.
