Could SpaceX be worth $12 trillion one day? Citi says Starship gets it a step closer.

Citi analysts suggest SpaceX's recent Starship test flight advances several priorities that could support a long-term valuation path toward $12 trillion, with a potential share price near $900 over time. The assessment frames Starship not as a single mission but as infrastructure: a reusable heavy-lift vehicle whose cadence and payload capacity underpin multiple business lines.

For markets, the takeaway is less about one launch than about execution risk. Starship's progress matters because it feeds directly into SpaceX's launch economics — particularly Starlink deployment, where lower cost per kilogram and higher flight frequency can improve unit economics. Analysts tracking the company's trajectory will likely watch whether test flights move from demonstration toward routine, high-cadence operations, since that transition is what converts technical milestones into revenue and margin assumptions.

Investors should note the context: SpaceX remains private, so the $12 trillion figure is a long-horizon scenario, not a current valuation. What to watch next includes Starship flight frequency, payload deployment success, Starlink subscriber growth, and any changes to the competitive launch landscape. Those operational signals, rather than the headline number itself, will determine whether the projection gains credibility over time.
