HBM Supply Shortage Persists as SK Hynix Commands 56.4% Market Share; Micron Commits $250B to Domestic DRAM Expansion
SK Hynix's SEC filing confirms it holds 56.4% of the HBM market amid a verified global shortage affecting data center builders, with demand for its US listing running 7x oversubscribed — underscoring persistent HBM supply tightness directly impacting AI accelerator BOM costs. Concurrently, Micron has committed $250 billion in US DRAM manufacturing investment through 2035, targeting 40% of its DRAM output domestically, with ground broken on a New York fab on July 9, 2026.
The combination of a verified HBM shortage, SK Hynix's dominant 56.4% share, and Micron's record 87% data center gross margin confirms that HBM pricing power remains firmly with suppliers — H200/B100 integrators face structurally elevated memory BOM costs through at least 2026, with meaningful domestic supply relief unlikely before Micron's New York fab reaches volume production later this decade. The $250B CapEx commitment is a long-duration supply signal that does not alleviate near-term tightness.
