JPMorgan Chase (JPM) CEO Jamie Dimon has his doubts that the AI spending boom will turn out the way investors are hoping for. Still, he's willing to entertain one of the AI build-out's more extraordinary projects: SpaceX's ambition to put data centers in space. When asked if the market is pricing in a perfect outcome of the AI boom, Dimon said, "Not perfect, but probably a good outcome." SpaceX's stock rose in its first three days of trading but has since tumbled, reaching a new low on Monday before regaining ground on Tuesday. When asked how much he thought about SpaceX's listing price, Dimon said "quite a bit."
