SpaceX just filed for what could be the biggest IPO ever

Elon Musk's final frontier is officially open for business now that SpaceX has formally filed its S-1 prospectus with the SEC. That kicks off what could be the largest initial public offering ever when it lists on the Nasdaq stock exchange with the ticker SPCX. According to the filing, SpaceX generated $18.67 billion in revenue in 2025, driven largely by its Starlink satellite internet service.
