Shares of space companies soared in US trade on Wednesday following a report that technology multi-billionaire Elon Musk's SpaceX could this week file to list shares on the stock market.

The stock prices of rocket makers Firefly Aerospace and Rocket Lab rose by more than 10%, while other space-related firms also saw their shares jump.

SpaceX is expected to go public this year with a valuation of around $1.75tn (£1.31tn). The technology news outlet The Information reported that the firm could file for the initial public (IPO) within days.

The BBC has contacted SpaceX for comment.

SpaceX, which makes and launches rockets, could reportedly raise more than $75bn from the share sale. That would make it the biggest stock market debut in history.

Other space industry firms also saw their stock prices surge on Wednesday, including Intuitive Machines - which rose by nearly 15%, while shares of Earth-imaging company Planet Labs jumped by more than 10%.

Satellite maker Sidus Space gained nearly 19% and shares of AST SpaceMobile rose by 10%.

SpaceX was founded in 2002 by Musk, the world's richest man who also runs several other companies including electric car giant Tesla, the social media platform X and brain implant firm Neuralink.

SpaceX has in recent years become an aerospace powerhouse, securing billions of dollars in US government contracts and space projects.

The firm has other companies in its stable like xAI, which owns social media platform X and artificial intelligence (AI) firm Grok.

SpaceX also owns satellite firm Starlink, which provides internet services around the world.

The SpaceX share sale could make Musk the world's first trillionaire.

He currently has a fortune of more than $820bn, according to Forbes, which tracks the wealth of the world's richest people.

In 2025, Musk became the first person ever to achieve a net worth of more than $500bn.
