Thesis
The AI '25: Semis & Memory theme remains strongly bullish, driven by an accelerating memory supercycle and HBM demand projected to easily exceed $100B by 2027. Broadening AI applications and transformative strategic customer agreements ensure robust growth, despite massive capital intensity and persistent supply constraints.
Bull case
Unprecedented and accelerating High Bandwidth Memory (HBM) demand, with the Total Addressable Market (TAM) now projected to easily cross $100 billion in 2027, a year earlier than anticipated. Demand for HBM3E, HBM4, and HBM4E, alongside non-HBM DRAM and SSDs, far exceeds supply through 2028, ensuring strong pricing and volume for high-performance memory critical for AI applications.
Broadening AI applications, including agentic AI, AI PCs, and edge AI (e.g., robotics, automotive), are driving continuous demand for advanced semiconductors and memory. This extends beyond GPUs to include a resurgence in CPU demand for AI data centers and second-order beneficiaries in memory testing, semicap subsystems, advanced packaging, and silicon photonics, creating diverse growth opportunities.
Strategic Customer Agreements (SCAs) are fundamentally transforming the memory business model, with over $22 billion in upfront cash deposits across 16 non-cancellable multi-year agreements. These SCAs provide unprecedented revenue visibility and stability, covering roughly half of company revenue and de-risking future demand and massive capital expenditure.
Bear case
Massive capital intensity and execution risks due to significantly increased capital expenditure (e.g., ~$27 billion for Micron fiscal 2026, $60-$64 billion for TSMC in 2026, plus an additional $100 billion investment in Arizona, with even higher CapEx expected for 2027). Greenfield fabs will not contribute production bits until calendar 2028, incurring substantial startup costs and potential gross margin dilution (e.g., 2nm ramp, overseas fabs).
Persistent supply chain constraints and bottlenecks, particularly in advanced packaging (CoWoS) and leading-edge nodes, with overall aggregate supply for both DRAM and NAND remaining substantially below aggregate demand. Manufacturers are unable to meet a significant portion of customer needs, severely limiting overall market growth and potentially leading to delayed platform ramps for new technologies like MRDIMM.
Geopolitical tensions and trade restrictions, particularly involving key manufacturing hubs like Taiwan, remain significant concerns. Potential new tariffs or export restrictions on AI-related memory and semiconductors could disrupt global supply chains, limit market access, and negatively impact profitability, as these risks are often explicitly excluded from guidance. Intense competition from larger, well-funded rivals also poses a long-term threat.
