SpaceX Plans Share Sale to Push Valuation Beyond $400 Billion

SpaceX, the private aerospace company founded by Elon Musk, is reportedly preparing to raise fresh capital and sell insider shares in a transaction that could value the company at approximately $400 billion.

According to sources familiar with the discussions, the proposed deal would mark a record valuation for a privately held US company, eclipsing SpaceX’s previous valuation of $350 billion following its share buyback in December.

The new valuation would position SpaceX ahead of other global private giants, including ByteDance and OpenAI.

The fundraising plan is expected to include a primary round in which a limited number of new shares would be offered to investors.

Concurrently, SpaceX insiders, including employees and early-stage backers, would have the opportunity to sell shares in a secondary transaction, with the pricing to be determined by the primary offering.

SpaceX has yet to issue an official statement on the development.

The prospective valuation underscores investor confidence in SpaceX’s core businesses, driven largely by the rapid expansion of its Starlink satellite internet network.

Industry sources indicate that Starlink currently contributes more than half of SpaceX’s annual revenue, highlighting its role as a key growth driver for the company.

SpaceX is also advancing its Starship rocket program, aimed at revolutionising deep space travel and interplanetary missions. However, recent development efforts have faced technical challenges, including a significant explosion at its Texas test site in June.

Despite such setbacks, SpaceX remains one of the leading commercial rocket launch providers globally, with contracts spanning government, commercial, and international clients.

The company’s new funding strategy mirrors its 2021 fundraising round, when it secured about $850 million from investors. The final valuation will depend on the level of interest from new and existing shareholders, as well as the volume of insider shares available for sale.

The development comes as Elon Musk, the world’s richest person, continues to dominate headlines beyond the space sector. Musk is currently engaged in a public spat with US President Donald Trump over tax and spending policies, and has hinted at the possibility of launching a new political party—moves that could have implications for his sprawling business interests.

As SpaceX moves forward with the proposed share sale, market watchers will monitor whether investor appetite can push the company’s valuation to the historic $400 billion mark.

The outcome could further reshape the landscape for private capital markets and cement SpaceX’s position as the world’s most valuable privately held company.
