SpaceX is preparing to file its initial public offering application with the US Securities and Exchange Commission next week, according to a source. The aerospace company had previously filed a confidential initial document in early April, a standard step in the listing process. The second filing is expected to reveal financial statements and operational details to the public. SpaceX aims for a June listing on the Nasdaq electronic stock exchange, with an estimated valuation of approximately US$1.75 trillion, and hopes to raise up to US$80 billion. This IPO could potentially surpass the record set by China's Alibaba in 2014, which raised US$21.7 billion. Globally, the Saudi Aramco oil group holds the highest valuation. SpaceX has substantial capital requirements for its space projects, including the Starship rocket, the Starlink satellite internet network, the Terafab chip factory, and advanced AI models. Founded in 2002 by Elon Musk, who remains CEO and principal shareholder, the group also includes the AI startup xAI and the social network X, formerly Twitter.
