AI1 Capex: What the Prospectus Actually Commits To

The SPCX prospectus disclosed AI1 capex commitments through FY28. Here is what is actually authorised vs aspirational.

Authorised AI1 capex (3y)

~$8.5B

Pre-IPO capex spent

~$1.2B

Funded by

IPO proceeds + ops cash

What is actually committed

The S-1 lists $8.5B of authorised AI1 capex over the three years following the IPO. Roughly $1.2B was already spent on prototype hardware and ground testing pre-listing. The remaining ~$7.3B funds the first operational array — radiators, compute hardware, integration and launch — targeted for FY28 first revenue.

Funding sources are explicit: a portion of the $75B IPO proceeds plus operating cash flow from Starlink. AI1 does not depend on additional capital raises in the base case.

Key takeaways

  • AI1 capex is committed and funded; no additional raises required in base case
  • First operational array targeted FY28; first revenue same year
  • Track quarterly capex disclosures vs the $8.5B authorised envelope
