Nvidia and Tesla Bet Big on a $40 Trillion Humanoid AI Market

Nvidia is courting a $40 trillion TAM for humanoid robots with its Isaac Groot foundation model and a data-center surge, while Tesla scales Optimus toward mass production, signaling Wall Street’s push into a “physical AI” thesis that pairs Nvidia as the compute backbone with Tesla as the execution vehicle. The thesis is supported by Nvidia’s robust revenue growth (Q1 FY2027 total revenue around $81.6B, data center ~$75.25B) and Tesla’s 1.28 million active FSD subscriptions, but valuations remain elevated (e.g., Tesla forward P/E ~208x) as investors bet that billions of robots and autonomous systems will materialize in factories, warehouses, and beyond.
