Core Research: Investing in AI Infrastructure Choke Points

The SemiAnalysis Weekly podcast explores current choke points in the AI infrastructure supply chain. The discussion highlights constraints at nearly every layer, from TSMC's N3 node being sold out through 2027 to shortages in INP-based lasers used in optical transceivers and PCB substrates. The panelists note that while hyperscalers are facing stock declines, suppliers with the biggest shortages are experiencing gains, with networking being a key theme this year. Modular construction for data centers is also examined as a solution to labor shortages, with Comfort Systems identified as a key player. The conversation further dives into memory stocks, discussing the potential impact of OpenAI's letters of intent and the significance of prepayments in altering the financial dynamics of memory players.
