300mm fab equipment spending to hit US$227 billion by 2029, SEMI says

The 31% YoY jump in 2026 is not a cyclical bounce—it is a structural repricing of front-end capacity driven by AI accelerator demand. The more telling signal: the spending curve holds a double-digit slope through 2029, meaning EUV lithography lead times (already booked past 2027) will become a harder constraint than capex itself. On the tech stack, incremental capital is highly concentrated. HBM stacking, CoWoS advanced packaging, and GAA/CFET node migration will absorb over 70% of the spend, while mature-node investment gets systematically compressed. Applied Materials' dominance in etch and deposition will further entrench; Lam Research must prove its selective-etch irreplaceability in the 3D NAND layer-count race. Geopolitically, export controls have bifurcated the equipment market into two pricing regimes. TSMC, Samsung, and Intel's expansion cadence is now anchored by CHIPS Act subsidies and allied-capacity sharing. Equipment makers enjoy high order visibility, but customer-concentration risk scales in parallel. Over the next 18 months, the critical variable is not 'who spends' but 'who gets equipment first.' Bottlenecks will migrate from wafer fab to HBM supply chains, photoresist, and precursor chemicals—that is where the real profit redistribution behind the $227B number actually lives.
