Tech brief
Thursday signal: markets shrug at war, Meta's own silicon, and Micron's $250B
Day two of strikes meets a chip rally, Meta dates its Iris production run, Congress braces for a defense-money fight, and an AI agent raises its own round — press a signal for coverage.

The clean six-week test is the story — a working in-house chip turns Meta’s $100B-plus hardware budget from a captive Nvidia order book into a negotiation.
BackgroundMeta buys most of its AI computing power from Nvidia — one of its biggest costs. Like Google and Amazon before it, Meta has spent years designing its own chips, a family called MTIA, to loosen that dependence.
- Iris is one of four MTIA-family processors unveiled in March; Meta plans a new chip roughly every six months through 2027, twice the industry’s usual pace.
- Broadcom co-designs, TSMC manufactures — and the memo locks in Samsung memory, Sandisk storage and Sumitomo fiber, insurance against the component shortage.
- The chip’s jobs: training the ranking and recommendation systems behind Meta’s feeds, and running AI features in its apps; Meta still expects to spend heavily with Nvidia and AMD.
- The pattern is industry-wide: OpenAI unveiled a Broadcom-built chip last month, Anthropic is reportedly exploring silicon with Samsung, and Amazon and Google already run their own.

Memory chips, not processors, are now the bottleneck on AI — Micron is spending like the shortage will last years, and the market is pricing it that way.
BackgroundMicron is the only US-based maker of memory chips — the components that store data for AI systems and get consumed in huge volume by data centers. Memory prices have soared over the past year as AI demand outran supply.
- CEO Sanjay Mehrotra calls memory “in deep shortage” with no visible catch-up point — the pledge targets making 40% of Micron’s DRAM, the main type of memory chip, in the US across New York, Idaho and Virginia.
- A separate up-to-$3B goes into the domestic supply chain, including $500M for GlobalWafers’ raw-silicon plant in Texas.
- The stock is up 677% in a year on AI memory demand; Thursday’s announcement helped drive the main index of chip stocks 3% higher.
- Commerce Secretary Lutnick claimed the project creates nearly 100,000 jobs — political framing that ties the buildout to the administration’s manufacturing-reshoring scorecard.
