Meanwhile, CNBC cited sources who claimed that Elon Musk is considering combining Tesla with SpaceX.

Elon Musk’s SpaceX is hoping to raise $75bn in a gargantuan initial public offering (IPO), which estimates suggest would value the tech giant at around $1.7trn.

The Starship rocket producer, in a filing with the US government, said that it plans to offer more than 555.5m class A common stock shares at a value of $135 per share.

Last month, SpaceX posted a net loss of $4.28bn on revenue of $4.69bn for Q1, compared with a net loss of $528m on revenue of $4bn a year ago.

Musk’s decision to offer shares at a fixed price ahead of the order-taking is unusual for large US IPOs, reports suggested.

However, depending on its success, SpaceX could rank as the largest IPO listing in history, far exceeding the 2019 listing of Saudi Aramco for $29bn, the current record holder for largest IPO. Following the raise, Musk, the company’s chairperson, CEO and chief technical officer, is expected to hold more than 82pc of the voting power.

The space-tech company was last valued at a reported $1.2trn following the February acquisition of xAI, Musk’s other company, which is behind the AI chatbot Grok. This came less than a year after xAI acquired the social media platform X, another of Musk’s businesses.

Meanwhile, CNBC reported late last month that Musk is considering yet another SpaceX acquisition, this time of his electric vehicle manufacturer Tesla, which currently sits at around $1.6trn in value.

SpaceX’s filings showed that it had purchased nearly $700m worth of Tesla’s battery storage products across 2024 and 2025, as well as more than $130m of its Cybertrucks in 2025.

xAI, by April of this year, had purchased $292m in Tesla battery solutions, and more than $400m last year. Tesla, meanwhile, committed $2bn to xAI, while owning nearly 19m SpaceX shares at an approximate value of $2.5bn. The two companies are also collaborating to develop semiconductors as part of Terafab.

SpaceX’s IPO comes just ahead of Anthropic, which filed with the US Securities and Exchange Commission on 1 June. The AI giant behind Claude was last valued at $965bn after a $65bn raise late last month.

OpenAI, recently valued at $852bn, is also planning to go public. CNBC reported that the company was preparing to confidentially file for an IPO late last month.
