"We've seen a strong shift in company selling compute versus buying compute," says Noah Kann. He points out Alphabet (GOOGL) signaling negative free cash flow in earnings and its following stock sell-off as an example. Noah says it's all about the race to create the first "true" AI model that will generate phenomenal profits. Nvidia (NVDA) and several financial firms seek to finance $500 billion to AI infrastructure as a way to ease these woes, giving the Mag 7 giant a "kingmaker" role.
