The largest TAM
ever printed in an S-1.
SpaceX's filing puts $28.5 trillion of opportunity on the table: across launch, connectivity, AI, and a long tail of "futures." This is an interactive walk through the disclosed numbers: segment economics, what's claimed, what's missing, and the capture rate the market is already pricing in.
Business View
Revenue, EBITDA, capex, and R&D, broken out by segment, 2023 to Q1 2026.
Segment Revenue
2025 segment snapshot

TAM Capture Math
SpaceX captures 0.07% of its claimed TAM today. Drag the slider. At any valuation anchor, the implied capture rate is the question every IPO buyer needs to answer.
Even at $1.75T, the implied capture is 6.1% of a TAM number that's 80% aspirational AI software. Strip that out. TAM falls to $5.8T, current capture rises to 0.32%, and the $1.75T anchor implies ~30% capture of a more honest opportunity set. Where you stand on the AI TAM is where you stand on the valuation.
