The leading-edge foundry and IDM sector is in a structural growth phase driven by insatiable AI infrastructure demand, advanced packaging, and the proliferation of custom silicon (ASICs/XPUs). The global semiconductor market is projected to reach $1.29 trillion in 2026, with IDM IC market alone valued at ~$262 billion and growing at a 4.9% CAGR. Key tailwinds include AI model training/inference, HBM memory (HBM4 volume production in 1H26), automotive electrification, and Edge AI. However, the sector faces persistent geopolitical risk, escalating capex requirements (single fabs >$10B), wafer cost inflation (10-20% since 2025), and supply chain concentration concerns. The capital cycle is firmly in mid/late expansion with capacity tight at leading nodes (7nm and below), while 2nm ramp by TSMC and Rapidus (mass production 2027) signals continued investment.

| Ekspozycja na AI | Very high — AI infrastructure is the primary demand driver. AI chips require leading-edge logic (5/3/2nm), advanced packaging (CoWoS, 3D stacking), and high-bandwidth memory (HBM). Edge AI is an emerging second leg. |
The thesis is structurally supported by multi-year AI infrastructure buildout, memory recovery (HBM4), and government incentives (US CHIPS Act, Japan subsidies). Price elasticity remains low for leading-edge foundry output, underpinning pricing power. Risks from geopolitics and capex cyclicality are real but partially offset by secular demand visibility and supply discipline.
