By far the most capital in the stack, $388bn, but extraordinarily concentrated: a handful of foundation-model labs hold the overwhelming majority while the rest compete for what remains. For everyone outside the top few this is still an early market, with 56% of the field at Seed or Series A despite the headline figures.
