Only 1 Stock Is the Indispensable Backbone of the $1.8 Trillion Space Economy — and It’s Not SpaceX

The countdown to the SpaceX (SPCX) IPO is entering its final days, and the excitement is hard to miss. If the company debuts Friday at a valuation approaching $1.8 trillion, as many investors expect, it will immediately rank among the most valuable businesses on Earth. That valuation reflects more than just rockets. It reflects the growing importance of the global space economy, which industry forecasts project will expand from roughly $613 billion today to $1.8 trillion by 2035.

SpaceX itself thinks the opportunity is even larger. The company has pointed to a potential $28.5 trillion addressable market spanning launch services, satellite internet, defense, communications, Earth observation, lunar infrastructure, and eventually interplanetary transportation.
