Elon Musk's SpaceX is poised to become one of the most valuable publicly traded companies in the world. The company, which manufactures rockets, space exploration technology, and Starlink satellites, is currently privately held. But on Wednesday, it made a confidential filing with the US Securities and Exchange Commission (SEC) for an initial public offering (IPO), which would allow shares to be traded on the stock market. The value of SpaceX once it goes public is expected to surpass $1 trillion (£751bn), making its stock market debut one of the most financially significant in history. Musk's own holding in SpaceX would put the billionaire on track to become the world's first trillionaire. The company is aiming to officially go public sometime in June, according to reports in Bloomberg, Reuters, and the New York Times. A confidential IPO filing with the SEC allows a company to avoid immediately revealing information to the public while it requests feedback from the regulator. The next step will be for company executives to hold 'roadshows'—meetings with big investors to convince them to buy shares. By making shares of SpaceX available for purchase by the public, the company is looking to raise $50 billion or more. Earlier this year, SpaceX took over xAI, Musk's artificial intelligence venture, and is believed to have become the most valuable private company in the world, with an internal valuation of $1.25 trillion. Musk's various companies have been increasingly intertwined, and this consolidation may signal to investors that SpaceX is preparing for its IPO. Experts suggest that this move is essential for providing the cash infusion needed for the company's large-scale ambitions in space. Musk founded SpaceX in 2002 with the goal of reducing the costs of launching spacecraft, and today, the company also operates Starlink, a satellite network delivering global internet access. However, Musk speaks of broader goals, including establishing a self-sustaining city on Mars.
