SK hynix tops global memory chip market in Q3 2025: report

SK hynix maintained its position as the top global dynamic random access memory (DRAM) supplier in Q3 2025, according to Omdia, holding a 34.1% share of the market by sales.

This marked its third consecutive quarter in the lead, despite a 5.3 percentage-point drop from the previous quarter.

Samsung Electronics increased its share to 33.7%, while Micron Technology held 25.8%.

Global DRAM sales rose 30% quarter-on-quarter to US$40.3 billion, driven by higher prices.

SK hynix had overtaken Samsung in DRAM market share in Q1 2025.

🧠 Food for thought

Implications, context, and why it matters.

SK hynix’s lead narrows as Samsung closes gap and Micron surges

Top spot stays with SK hynix at 33.2% share while Samsung reached 32.6% for a 0.6 percentage point gap 1.
SK hynix led 3Q25 with $13.75 billion revenue but posted 12.4% quarter-over-quarter growth 1.
Samsung’s bit shipments beat forecasts with 30.4% revenue growth to $13.5 billion 1.
Micron posted the strongest growth at 53.2% quarter over quarter, reaching $10.65 billion and gaining 3.7 percentage points to capture 25.7% share 1.
High Bandwidth Memory (HBM) demand stays strong, yet conventional DRAM pricing and bit-shipment execution still drive results 1. Samsung and Micron are gaining as supplier inventories near depletion entering 4Q25 1.

Memory efficiency software and CXL vendors should accelerate enterprise outreach now

Conventional DRAM contract prices may jump 45-50% quarter over quarter in 4Q25 as inventories empty, so enterprises face pressure to cut total cost of ownership 1.
Modern server CPUs support CXL Type-3 devices (memory expansion modules attached over CXL), and demos put hybrid systems (servers mixing DRAM and CXL-attached memory) at 95-100% of DRAM-only throughput with 5-10µs (microseconds) added latency 2 3.
For CXL hardware vendors, the CXL market could reach $16 billion by 2028 3.
Memory compression and optimization software providers can use data that say CXL integration with compression may cut total cost of ownership by up to 50% in cold data storage scenarios (infrequently accessed data) 3.
AMD and Intel CPUs now support CXL memory expansion 2. Micron says customers expect solid demand through the rest of 2025 4.
