A legal pacing agreement among AI labs would hit Nvidia, because labs coordinating a training slowdown would stop buying the training hardware it sells. Dario Amodei's September 12 letter urging a slowdown seeks an antitrust waiver so labs can escape a costly training race while keeping profitable inference; Sam Altman and Elon Musk backed it, and Meta, with no inference margins to protect, said no. If Nvidia rallies on a waiver, this reading is wrong; cloud capex calls are the first check. x.comÂ
