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, which would allow shares to be traded in the stock market. The value of SpaceX once it goes public is expected to surpass $1 trillion (£751 billion). That would make its eventual stock market debut one of the most financially significant in history. Musk's hold in SpaceX would position him to become the world's first trillionaire. The BBC has contacted SpaceX for comment. Reports indicate that the company aims to officially go public sometime in June. A confidential IPO filing with the SEC allows SpaceX to avoid immediately revealing information while it requests feedback from the regulator. The next step will involve holding 'roadshows' to entice big investors to buy shares. By offering public shares, SpaceX is looking to raise $50 billion or more. Earlier this year, SpaceX acquired xAI, Musk's artificial intelligence venture, which has elevated its internal valuation to $1.25 trillion, solidifying its status as the most valuable private company. The recent consolidation of Musk's companies signals that SpaceX is preparing for its public debut, as investor confidence grows. Industry analysts suggest that the capital influx from the IPO is vital for SpaceX to meet the demands of its ambitious goals, including operating Starlink and potentially establishing a human presence on Mars.
