The Metals Bill | What the AI Buildout Runs On — & Where It Jams
The binding constraints on AI infrastructure are not chips or capital. They are a short list of cheap-but-critical metals—split between a manufacturing queue and a licence issued in Beijing.
The AI buildout is capital-rich and input-constrained. The parts that photograph well—GPUs, models, the concrete shells rising out of the desert—are not what jams the pipeline. The binding constraints sit one layer down, in the physical layer’s bill of materials: a handful of metals, most of them a rounding error on project cost, none of them easily substituted. The risk they carry shows up not as price but as lead-time and licensing—and it falls into two families, one that behaves like a manufacturing queue, one that behaves like a geopolitical option.
