   TSMC $265B US CapEx Commitment + ASML 30% EUV Capacity Surge Signal Multi-Year AI Supply Expansion — with Equipment Price Hike Risk

   TSMC has committed an additional $100B in US manufacturing investment (total $265B) while confirming 2026 CapEx at the high end of $52B–$56B guidance, directly supporting CoWoS and advanced-node wafer capacity for AI accelerators including Nvidia H200/B200 SKUs. Concurrently, ASML — the sole supplier of EUV lithography equipment critical to HBM and leading-edge logic fabs — raised its 2026 revenue outlook by ~$6–7B to €43–45B and announced 30% annual production capacity expansion for both EUV and DUV systems over the next two years, while separately reporting active negotiations to raise tool pricing, with TSMC reportedly resisting increases on both EUV and DUV equipment.

   SK Hynix CEO Flags 2027 as Worst-Ever HBM Supply Crunch; $26.5B IPO Capital Earmarked for Capacity Expansion

   SK Hynix CEO Kwak Noh-Jung publicly stated that 2027 will represent the worst supply shortage in the memory industry's history, with demand forecast to exceed production capacity beyond 2030, according to a Reuters interview conducted on July 10, 2026. Concurrently, SK Hynix raised $26.5B in its Nasdaq ADR debut — the largest-ever US IPO by a foreign company — with proceeds explicitly allocated to a new South Korean fab, a new packaging facility, and EUV scanner procurement to address AI-driven HBM demand.

   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.

   SK Hynix Commits $706B to HBM/DRAM Scale-Up as ISM Flags Memory Components in Active Short Supply

   SK Hynix, the dominant HBM supplier to Nvidia, has committed KRW 1,100 trillion (~$706B) within SK Group's broader $1.36 trillion investment roadmap to scale HBM and next-generation DRAM production capacity, while a separately announced KRW 20 trillion P&T7 advanced packaging facility (targeting 2027 completion) signals a direct push to relieve CoWoS-adjacent packaging bottlenecks. Concurrently, the ISM June services survey explicitly flagged memory components as having shifted from 'more expensive' to 'now in short supply,' introducing near-term allocation risk for AI accelerator BOMs ahead of capacity coming online.

   Samsung & SK Hynix Commit $518B South Korea Fab Buildout, Signaling Multi-Year HBM Supply Expansion

   Samsung Electronics and SK Hynix have jointly announced construction of four new semiconductor fabrication plants in South Korea's southwest (Gwangju region), backed by a combined 800 trillion won (~$518B) investment unveiled at a June 29 government event, with supplementary government co-investment of 5–81 trillion won across regional packaging and fab clusters. The scale of committed CapEx — among the largest coordinated semiconductor investment announcements on record — directly expands future HBM and advanced packaging supply capacity, with Samsung Electro-Mechanics additionally earmarking 15 trillion won specifically for AI server package substrates in Busan.

   South Korea Commits $518B HBM & Packaging Capacity Supercycle; Nvidia China Revenue Under Structural Pressure from Huawei

   Samsung Electronics and SK Hynix have jointly committed 800 trillion won (~$518B) to construct two new chip fabrication sites each in South Korea's southwest region, with an additional 81 trillion won earmarked for an advanced chip packaging cluster in the Chungcheong area — representing the largest single sovereign-backed capacity expansion commitment in HBM and advanced packaging history. Concurrently, AP News reports Nvidia's AI chip sales in China are stalling as Huawei captures domestic share, introducing a structural demand-mix risk that could compress Nvidia's addressable volume for H200/B100-class SKUs in the world's second-largest AI market.

   HBM3e Contract Prices Rise 20% as AI Memory Demand Outstrips Supply

   HBM3e contract pricing rose ~20% quarter-over-quarter as SK Hynix, Samsung and Micron allocate 2026 capacity against booked AI-accelerator demand. With HBM the largest single line in modern accelerator BOMs, the increase flows straight into device cost.
