Market Transformation: From "Narrative" to "Physical Limits"
This week, market logic is undergoing a fundamental transformation. Smart Money is heavily focused on solving the physical bottlenecks of the 2nm generation in the critical supply chain. This is not short-term speculation, but rather an early strategic positioning for the 2026 capacity threshold.
Five Key Conclusions
📊
🎯 Capital Flow Guidance
Capital is converging from broad AI concepts, focusing on the three physical limit solutions: "thermal management (liquid cooling), transmission (CPO), and packaging (advanced substrates)." Capital is re-rating "who can solve the physical problems after Moore's Law slows down."
🚀 Server Iteration Dividends
Market attention has moved beyond GB200 and is beginning to price in the 2.5x capacity expansion wave for 2026's GB300 (Rubin platform). The exponential increase in rack weight and pin count will directly benefit high-load server rails and high-end connector groups.
💎 Optical Communication Technology Transformation
1.6T transmission necessitates a paradigm shift in technology, with CPO (Co-Packaged Optics) officially replacing pluggable modules as the mainstream. Manufacturers possessing laser light source and silicon photonics epitaxy technology command a very strong scarcity premium.
🏰 Packaging and Testing Capacity Moat
As TSMC's 2nm process comes to fruition, the doubling of test time and surge in substrate layers (26 layers+) create extremely high capacity barriers, effectively deterring lower-tier competitors and forming an oligopolistic landscape where "the strong get stronger."
⚠️ Structural Risk Warning
Non-AI memory (DRAM/Flash) valuations are excessively high, requiring caution regarding valuation correction risks; some capital is shifting into finance and tourism for defensive positioning, suggesting that the market, despite its enthusiasm, maintains risk awareness.
