    HBM4 Mass Production Race Accelerates: SK Hynix Leads, Samsung Surges, Supply Locked Through 2026 Amid ~$950B Deal Wave

    SK Hynix commenced HBM4 mass production in Q2 2026 with yield stability described as 'approaching mature-generation levels,' while Samsung guided Q3 2026 HBM4 revenue at 3x Q2 levels and targeted parity with its overall DRAM market share in HBM by H2 2026; both vendors confirmed HBM4E sample shipments are underway for 2027 qualification cycles. Against a backdrop of fully sold-out HBM capacity across all three major suppliers through 2026, South Korean vendors locked in AI chip supply agreements through 2030 via a reported ~$950 billion US deal package, with SK Hynix also signing a confirmed multi-year technology partnership with Nvidia specifically for next-generation AI memory.
