SpaceX isn’t just trying to get humans to Mars anymore. According to ARK Invest, the company’s Starship launch system is the linchpin of a $28.5 trillion total addressable market, with the vast majority of that figure, somewhere between $22.7 trillion and $26.5 trillion, tied directly to artificial intelligence infrastructure in orbit.
The math behind space-based AI
The company filed its S-1 in June 2026, laying out the $28.5 trillion TAM figure ahead of its IPO. In that filing and in a separate FCC application from late January 2026, SpaceX outlined plans for a constellation of up to 1 million satellites designed specifically for AI workloads.
The satellite design, called AI1, is built around efficient heat dissipation using radiators, integrated solar power, and Starlink-style connectivity. ARK analysts Daniel Maguire and Brett Winton have noted that these AI satellites would actually be simpler than existing Starlink units.
The economic argument hinges on Starship’s reusability. SpaceX has driven launch costs down by approximately 95% since 2008, and ARK believes the trajectory points toward costs below $100 per kilogram to orbit. ARK’s analysis suggests these space-based compute facilities could become economically viable within 2-3 years.
