Silicon Valley Insider: "Forget AI Stocks" (Ad)

A 25-year Silicon Valley veteran who recommended Nvidia before its 32,000 percent run says the next wave of AI gains wont come from Nvidia, Tesla, or SpaceX. He points to a detail buried on page 37 of the SpaceX IPO filing, tied to Elon Musks plans for 1 million AI satellites, 1 billion humanoid robots, and 200 billion AI chips a year. He says one overlooked sector could benefit most from this spending, and has identified a company trading under $1 that may factor into Musks supply chain.tc pixel
