(FILES) SpaceX, Twitter and electric car maker Tesla CEO Elon Musk looks on as he speaks during his visit at the Vivatech technology startups and innovation fair at the Porte de Versailles exhibition center in Paris, on June 16, 2023. SpaceX's filing with US regulators was revealed on May 20, 2026, laying out plans for what could become the largest initial public offering in history as Elon Musk's rocket and satellite company seeks to raise up to $75 billion on the public markets. The filing with the Securities and Exchange Commission -- the first time SpaceX has publicly disclosed detailed financial information -- revealed that the company generated $18.7 billion in revenue in 2025 and posted an operating loss of $2.6 billion as it poured money into next-generation rocket development and AI.
