In a separate post, Musk also addressed the commercial spaceflight company’s Total Addressable Market (TAM), which, in SpaceX’s pre-IPO prospectus, was at $28.5 trillion, with a majority of that market opportunity lying with artificial intelligence pursuits.

User James Cat, in a post on X, hinted that SpaceX’s TAM could be higher than the $28.5 trillion figure. “We were wrong. It is vastly higher than that,” the CEO said in his response. Musk did not provide any further details.
