SpaceX is now publicly traded at nearly $1.8 trillion（約290兆円） valuation, but investors are betting primarily on AI services from space rather than traditional space business.

What happened: SpaceX began trading on Nasdaq on Friday at $135 per share, closing the day at $160.95 (up more than 19 percent). The company is now valued at nearly $1.8 trillion（約290兆円）, and founder Elon Musk's personal stake is valued at more than $700 billion（約110兆円）.

Why it matters: The company's S-1 filing revealed that space-enabled solutions and the Starlink internet constellation make up less than 7 percent of SpaceX's total addressable market value. Instead, Musk and SpaceX view the majority of their value as coming from providing AI services, mostly from space and primarily for enterprise applications — meaning shareholders expect the company to focus resources where they believe the real profit lies.

What to watch: As a publicly traded company, SpaceX is now subject to significant public disclosures and will conduct much of its business in the public eye. Musk retains complete autonomy over ownership and voting rights, but he is now beholden to shareholders through stock price performance.
