SpaceX has outlined plans for what would be the largest initial public offering on record, according to a filing submitted to the Securities and Exchange Commission. The company, led by Elon Musk, is seeking to raise $75 billion by selling 555,555,555 shares of common stock at $135 each.
If completed at that size, the offering would more than double the current IPO record set by Saudi Aramco, which raised $29 billion in 2019. The proposal marks a significant step for one of the world’s most valuable private companies and follows the release of SpaceX’s initial S-1 filing a week earlier. That document gave investors a rare view into the company’s finances, business structure, and stated mission.
The filing also indicates that Musk, who serves as chief executive, chief technology officer, and chairman of the board, would retain substantial influence after the public listing. Under the proposed share structure, he would control about 82% of the voting power of the company’s common stock. Such an arrangement would allow Musk to maintain broad authority over corporate decisions even as SpaceX enters the public markets.
An S-1 registration statement is a required part of the process for companies preparing to go public. SpaceX is expected to make its stock market debut this month, though final timing and terms can change before the offering is completed.
The prospective listing comes during a period of heightened attention on large technology companies considering public offerings. Other closely watched names include OpenAI and Anthropic, both of which have drawn investor interest because of their roles in artificial intelligence. For SpaceX, the IPO would represent a major transition from private ownership to broader public investor participation, while preserving Musk’s central role in the company’s governance and strategic direction. Market response will depend on demand, valuation, and regulatory review.
