Nvidia to expand substrate capacity over next three years

The signal here is less the expansion itself than the absence of any disclosed figure or target, which leaves the scale of the commitment unverifiable for now. Substrate capacity is a supply-chain chokepoint rather than an end product, so the move reads as a bet that demand durability justifies multi-year buildout. The audience that matters is the substrate supplier base and the broader AI hardware supply chain, which has been shaped by exactly this kind of upstream constraint. Whether the three-year timeline translates into disclosed capex or firm capacity numbers is the open question.
