AI Infrastructure Supply Risk Intel

AI infrastructure is no longer a chip-only demand story. This hub tracks how AI data centers reserve foundry capacity, memory, advanced packaging, power delivery, optical links, and regional manufacturing options.

  • Week 31: The Shortage Moved to a Material You Don't Buy: Week 31: the shortage stopped being about memory. Lumentum's CEO says indium phosphide is running more than 30% below customer need and will become more acute than the memory squeeze. Corning's Optical Communications grew 32% with its AI data-center line up 65%, GlobalFoundries signed a proposed $300M CHIPS silicon-photonics LOI, and UMC's Singapore photonics cleanroom ramps late 2027. Meanwhile the general-purpose base came back — and Renesas is retiring a 50-year-old 6-inch analog and discrete line without a date. The honest counter: a 94.1% revenue forecast against 7.4% more silicon area shipped.
  • Week 30: You Can Lock a Year of Supply and Still Not Know the Price: Week 30: the buy side stopped waiting and started signing — and what it signed away was optionality, not price. TSMC is reportedly planning 2027 wafer increases up to 25%; Intel and AMD reportedly locked about a year of Chinese server CPU volume without fixing price; NVIDIA and SK Group put more than $500 billion behind AI factories and memory. The honest counter is IDC's PC and smartphone unit declines.
  • Week 29: The Money Showed Up. The Permission Didn't.: Week 29: TSMC committed ~$100B more to Arizona 2nm fabs and advanced packaging, funding the packaging gap — but New York's first US statewide data-center moratorium moved the binding constraint from capacity to permission. The money is arriving at every upstream layer; each dollar still has to pass a permit, a power contract, or an end-use rule.
  • Week 28: The Shortage Got a Deadline — It's Years Out: Week 28: SK Hynix's CEO called 2027 the worst year of the memory shortage and expects demand to outrun supply beyond 2030 — backed by a $26.5B IPO. The suppliers are financing a multi-year shortage, and the bottleneck is spreading past memory to packaging, racks, and power.
