SpaceX

What it is
SpaceX (Space Exploration Technologies Corp.) is a space launch, satellite, and spacecraft company founded by Elon Musk in 2002, operating the Falcon 9 and Falcon Heavy rockets, the Starlink satellite broadband constellation, and the in-development Starship vehicle. It was for most of its history the world's most valuable closely held private company before going public.
Why it matters lately
SpaceX filed its S-1 prospectus on May 20, 2026 and priced its IPO on June 11, 2026 at $135 per share, listing on Nasdaq under ticker SPCX on June 12, 2026 at an initial valuation of about $1.77 trillion in what was reported as the largest IPO in U.S. history. The stock closed its debut day up about 19% near a $2.1 trillion market cap, but by late July 2026 shares had fallen roughly 50% from that post-IPO peak; the company also disclosed cumulative Starship R&D spending exceeding $15 billion, including $3 billion in 2025 alone.
Asymmetric Analytics view
Inference (AA): SpaceX's transition from private company to a trillion-dollar-plus public equity, intertwined with Elon Musk's other ventures, creates a major new node of founder-concentration and valuation risk relevant to ELSI's actor-network analysis.
