DRAM
DRAM demand is spreading across memory for AI accelerators and for host systems. Micron reports volume production of HBM4 and SOCAMM2, while newer server modules are still being qualified. Buyers should check capacity and qualification for each product. AI growth may not keep suppliers stable or make every memory type equally available.

Core thesis
The DRAM industry consolidated to three players after decades of brutal competition. AI demand (HBM) is the growth driver. Conventional DRAM growth is modest; HBM grows 60%+ annually. China's CXMT is attempting entry but export controls limit access to advanced equipment. The oligopoly structure means rational pricing and sustained margins — a stark contrast to the commodity cycles of the past.
State of the art (2026)
The 2026 memory supercycle is real and HBM-led. NVIDIA certified all three makers — SK hynix, Samsung and Micron — for Vera Rubin HBM4 supply on 5 June 2026, and HBM4 entered mass production in February. SK hynix holds roughly 60–70% of Rubin HBM4 volume and is already sampling 12-high HBM4E; it has sold out its entire 2026 HBM allocation, as have Micron and Samsung. The pivot to HBM has starved commodity supply: Samsung guided Q1 2026 memory ASPs up about 146% year on year, with SK hynix DRAM ASPs up in the mid-60s. By share, Samsung (~38%) still leads conventional DRAM ahead of SK hynix (~29%). The open question is whether HBM pricing corrects once 2027 capacity lands.
