The author is bullish on AI infrastructure beneficiaries with US domestic capacity, particularly Meta, Corning, and Micron, citing strong demand signals and a virtuous cycle of AI-driven revenue growth supporting continued capex.

Several pieces of information emerged last night: 1. Micron's bet on capacity for 2028. 2. Meta and Corning signed a $6 billion data center fiber optic cable order. 3. Seagate and Texas Instruments both reported earnings; Seagate's earnings beat expectations, Texas Instruments' Q4 performance was slightly below expectations, but the guidance for the next quarter is very good. First, TSMC and Micron are investing real money, with layouts measured in years; this is the certainty of long-term demand. Meta is very representative. The market has always worried that Meta's annual capital expenditure of tens of billions of USD would drag down performance, but when advertisers find that every dollar brings higher conversion, Meta's revenue capability strengthens. This is a virtuous cycle. Strong Cash Flow supports buying fiber optics from Corning and chips from Nvidia. As long as the logic of AI -> improved ad effectiveness -> increased revenue persists, Meta's investment will not stop. Meta's signing with Corning emphasizes US capacity and the surge in fiber optic prices, indicating that the cost of building AI infrastructure domestically in the US is far higher than overseas; this hard tech inflation is real. Companies with domestic US capacity, such as Corning and some of Micron's production lines, will receive higher order priority.
