Key quotes
The SpaceX S-1 filing claimed that the company has 'the largest actionable total addressable market in human history' and highlighted AI as representing most of that opportunity at an estimated $26.5 trillion market—a number that comes close to rivaling US nominal GDP that stood at nearly $32 trillion in the first quarter of 2026.
SpaceX described its traditional space launch and satellite business as playing a supporting role to its fledgling AI business.
