Inside the AI hardware stack, from Nvidia's chips to the grid that powers them
An AI data center is seven layers of hardware: GPUs, memory, storage, CPUs, networking, manufacturing, and power. Here's the full map, with the public companies behind each layer and where the bottlenecks actually are.
A senator sold Apple and Nvidia in June. He bought Coherent and Micron instead.
Senator Sheldon Whitehouse's latest disclosure shows he sold Apple and Nvidia in late June, then bought Coherent and Micron the same week. Here's what the filing actually shows, and how each stock has moved since.
SemiAnalysis says Nvidia's Kyber AI rack is delayed to 2028: what it means for NVDA, AMD, and the photonics trade
SemiAnalysis says Nvidia's Kyber NVL144 rack is delayed more than a year to 2028, its backup design was scrapped, and Rubin Ultra was quietly cut in half. NVDA barely moved and AMD jumped instead. Here's what it means for the wider photonics trade, from Coherent and Lumentum to POET Technologies.
Today's AI rotation map: out of the chips, into software, power and the frontier
A snapshot of Monday's rotation: as the AI build-out sold off, money moved into software (ServiceNow, Adobe), AI power (GE Vernova), quantum, space and cyber. A one-day picture that can flip fast.
It is not just the chips: optics, memory and the neo-clouds all sold off this morning
The whole AI build-out sold off Monday morning, not just semiconductors. Optical names like Coherent (COHR) led the drop, memory (MU) and the neo-clouds fell hard, and Nebius (NBIS) was the lone holdout. What is going on.
AAOI cracks its floor: why photonics is getting routed today, and why the AI optics story holds
AAOI is down 14% into the $140s and the whole optical complex is bleeding. A deep dive into the sector rout, the broken chart, and why the long-term AI photonics thesis is still intact.
The AI stock map: every layer of the trade, from sand to software
A top-to-bottom deep dive on the AI supply chain, from the machines that make the chips down to the hyperscalers writing the checks, and how every layer pushes and pulls on the others.
