What happened
TSMC, Samsung, and SK Hynix are escalating competition for AI chip dominance, driven by projected trillion-dollar semiconductor demand in 2026. TSMC maintains its 70% share of the global foundry market, with strong demand for 3nm and 2nm processes, and analysts project gross margins near 58%. Samsung plans a $73 billion capital expenditure for 2026, a 22% increase, to expand memory and advanced logic capacity, pushing 2nm technology and targeting over 30% HBM market share. SK Hynix leads the HBM market with an estimated 50-62% share, leveraging HBM3E and HBM4 execution and a 'One-Team' alliance with TSMC.
Why it matters
This intensified competition shifts the landscape for procurement teams and platform engineers. Supply chain concentration in Asia, where industry capital expenditure is projected to exceed $136 billion in 2026, creates potential bottlenecks and geopolitical risks for sourcing critical AI components. For investors, the sustained, high-margin demand for logic and specialised memory transforms the semiconductor industry from cyclical to a supercycle, though yield issues and packaging constraints remain challenges. This follows AMD's pursuit of Samsung HBM, indicating a broader industry effort to diversify high-bandwidth memory supply.
