SpaceX is rated a sell, as its $1.43 trillion equity value bakes in highly optimistic outcomes across Connectivity, Space, and AI segments. Starlink drives profitability, but declining ARPU and limited scale mean it cannot alone justify SpaceX's current valuation without extraordinary AI or space success. AI and Space segments are deeply unprofitable and capital-intensive, with AI contracts short in duration versus long-lived infrastructure commitments, raising risk.
