What is SpaceX?
SpaceX is an American space launch and satellite communications company founded by Elon Musk in 2002, which went public in June 2026 in the largest IPO in history. Its post-IPO performance has become a bellwether for tech valuations and AI infrastructure investment, with early gains followed by a sharp decline.
