Musk says SpaceX's $28.5T market estimate was wrong, real figure 'vastly higher'
Elon Musk said in an Oct 19 post on X that SpaceX's estimate of a $28.5 trillion total addressable market (TAM) in its IPO filing was wrong and that the real figure is "vastly higher", without giving a new number, calculation method or timeframe. SpaceX's S-1 split the TAM into about $370 billion in space-related services, $1.6 trillion in connectivity and $26.5 trillion in AI, with roughly $22.7 trillion of the AI portion attributed to enterprise AI applications and $760 billion to consumer subscriptions. Reports note that TAM is a company estimate of the market its products could theoretically reach, not SpaceX revenue, orders or valuation, and that the filing excludes China and Russia from its global estimates. Coverage also cites the Colossus 2 data center in Memphis, a proposed Starmind orbital AI compute constellation, and Musk's Oct 15 claim that SpaceX's market value could reach $100 trillion in under 10 years.
About 90% of SpaceX's stated $28.5 trillion TAM comes from AI segments, so the disputed figure is largely a bet on AI compute and application demand rather than on rockets or broadband.
