SpaceX Files Confidentially for IPO in What Could Become the Largest Listing in History

SpaceX has filed confidentially for an initial public offering, sources familiar with the matter told Bloomberg on Wednesday, setting the company on track for what could become the largest public listing in history at a valuation potentially reaching $1.75 trillion. The confidential filing, confirmed by multiple reports including TechCrunch and Bloomberg, allows SpaceX to prepare its public offering documents without disclosing financials to competitors before a formal roadshow. Companies using the confidential filing process typically become public within six months; sources indicate SpaceX is targeting a June listing. At a $1.75 trillion implied valuation, SpaceX would debut as the most valuable company ever to go public, surpassing Saudi Aramco's 2019 IPO and dwarfing any listing in the technology sector. The company's businesses span Falcon and Starship rocket launches, the Starlink global satellite internet service, and its own AI and defense divisions. Bloomberg noted the timing as coming ahead of potential IPOs from AI-native rivals, suggesting SpaceX is moving to capture market momentum while investor appetite for frontier technology companies remains elevated following OpenAI's $852 billion funding close this week. SpaceX is majority-owned by Elon Musk, who also controls Tesla and xAI. A public offering would crystallize enormous paper wealth for early investors and employees while potentially giving Musk a new source of capital for future ventures. The company has historically resisted going public, with Musk citing a desire to avoid short-term earnings pressure on long-horizon projects like Mars colonization. The decision to pursue an IPO now reflects both the maturity of SpaceX's revenue streams and the scale of capital markets interest in AI-adjacent infrastructure. Bloomberg and TechCrunch reported the confidential filing on April 1, 2026.
