SpaceX made its public market debut on June 12, 2026, with shares climbing 19% on the first day of trading — a strong opening for what analysts are describing as the largest initial public offering in history.
The aerospace and rocket company, founded by Elon Musk, has long been one of the most anticipated IPO candidates in the private market. The first-day gain signals robust investor appetite for the stock. Institutional demand had already shaped the offering, with retail investors receiving a smaller allocation of shares ahead of the listing.
The debut adds momentum to a broader technology and innovation sector rally. OpenAI recently submitted a confidential IPO filing, suggesting major private technology firms are increasingly looking to access public capital markets in 2026.
