(SeaPRwire) –   According to a report from The Information, SpaceX may file for its initial public offering within days, potentially initiating the largest stock market debut ever.

The company is reportedly aiming for a valuation of approximately $1.75 trillion. If the reported $75 billion or more is raised in the share sale, it would set a new record for IPOs.

News of the potential filing led to a sharp rise in space stocks on Wednesday. Firefly Aerospace saw the most significant gains, increasing by 16% during the day.

AST SpaceMobile and Rocket Lab each experienced gains of around 10%. York Space, which completed its own IPO in January, rose by 5%.

AST SpaceMobile, Inc., ASTS

Intuitive Machines saw an increase of nearly 15%. Planet Labs jumped by more than 10%, and Sidus Space gained close to 19%.

Elon Musk, who founded SpaceX in 2002, also leads Tesla, X, Neuralink, and xAI.

Last month, SpaceX acquired Musk’s xAI, with the combined entity valued at $1.25 trillion in that transaction.

Forbes reports that Musk’s current net worth exceeds $820 billion. A SpaceX IPO at the reported valuation could propel his personal wealth beyond $1 trillion.

Over the past two decades, SpaceX has established a strong presence in the aerospace industry and holds billions of dollars in U.S. government contracts.

SpaceX’s Satellite and Defense Business

The company operates Starlink, a satellite internet service with over 9,500 satellites currently in orbit. Musk’s January proposal to expand this constellation to 1 million satellites has faced criticism from scientists regarding environmental concerns.

The space sector has also benefited from President Donald Trump’s proposed “Golden Dome” defense system, which has increased investor interest in companies focused on national defense and satellite technology.

Data Centers in Space

There is growing consideration for establishing data centers in space as a response to escalating electricity costs on Earth. The rapid expansion of AI infrastructure has increased power demand, making space-based solutions an area of interest.

However, this concept faces significant challenges, including high launch expenses and limited rocket availability.

SpaceX has not yet confirmed the IPO filing. The BBC reported that SpaceX has been contacted for comment but had not responded at the time of publication.

Firefly Aerospace, which went public in August 2025, saw a 16% increase on Wednesday. York Space, which listed in January 2026, gained 5%.
