A Bernstein report titled "How Much WFE Do We Need to Achieve AI Nirvana" projects cumulative Wafer Fab Equipment (WFE) demand of $736 billion from 2027-2029, with annual figures of $200 billion, $245 billion, and $291 billion respectively, to support 70GW of annual US data center deployment by 2030. The report highlights that new wafer capacity additions for DRAM, NAND, and HBM combined account for 89% of the AI semiconductor equipment cycle's center of gravity, with advanced logic at 11%. Each additional 1GW/year of compute deployment capacity requires 46,000 wafers/month of new capacity, corresponding to $7.5-8 billion in equipment investment.
The AI infrastructure buildout is shifting WFE demand heavily towards memory, with deposition and etch equipment gaining prominence over advanced photolithography.
