Saturday signal: Hormuz talks, Meta silicon, and housing without a signature

Ceasefire rhetoric vs. diplomacy, custom chips, SoftBank retail capital, and a law that landed at midnight — press a signal for coverage.

Iris is a bargaining lever as much as a chip — every working in-house chip weakens Nvidia's pricing power over Meta's $145B-a-year infrastructure budget.

BackgroundMeta buys most of its AI computing power as Nvidia graphics chips — one of its largest costs. Like Google and Amazon, it has spent years designing its own chips, a family called MTIA, to loosen that dependence.

Points
  1. Iris is one of four chips in the MTIA family; the memo targets a new chip roughly every six months through 2027.
  2. The chip’s jobs: training the ranking and recommendation systems behind Meta’s feeds, plus running generative-AI features in its apps — augmenting, not ditching, Nvidia and AMD hardware.
  3. The same memo plans ~7 gigawatts of computing capacity this year, doubling toward 14 GW in 2027, against 2026 spending guided as high as $145B.
  4. It also locks in suppliers beyond the chip itself — Samsung memory, Sandisk storage, Sumitomo fiber — insurance against component shortages at data-center scale.
