AWS is adding substantial operating profit alongside revenue, challenging the case that Amazon's AI buildout lacks earnings power. About $6.3B of incremental profit on $13B of revenue implies nearly 49% incremental margins; inference and Trainium could improve economics. But depreciation lags, AI margins remain lower and $220B planned cash CapEx leaves returns uncertain. If profit and cash flow catch up, the selloff may underestimate long-term earning power; otherwise the discount is deserved. x.comÂ
