It’s official: SpaceX is on track to be the largest IPO in history, seeking to raise $75 billion once it goes public later this month.

The company will sell 555.6 million Class A shares at a fixed price of $135 each, according to an amended statement filed with the SEC on Wednesday. Combined with the company’s total shares outstanding, that prices SpaceX at roughly $1.77 trillion; enough to make it, on arrival, the seventh-largest company in the U.S. per the Fortune 500 list, walloping current no. 7 spot Berkshire Hathaway, and even CEO Elon Musk’s other darling, Tesla, which trades at a market cap of about $1.6 trillion.

The company going public is not just a rocket maker, anymore. February’s all-stock absorption of xAI turned SpaceX into a money-losing satellite-internet and AI conglomerate, with proceeds earmarked partly for expanding AI compute alongside the Starlink network. Musk makes the goal in the prospectus very clear: get a colony of a million people on Mars. The rockets are to transport there, and the AI is to organize the colony and also figure out how to get a million people on Mars.How much of the $80 billion actually reaches that buildout is another question: as Fortune has reported, more than three-quarters of the proceeds are already spoken for, pledged to repay debt held by Valor Equity Partners, X Corp, and xAI investors, and to pay EchoStar for a spectrum acquisition, leaving less than $18 billion for the AI express.
