TLDR

• SpaceX could file for its IPO within days, targeting a $1.75 trillion valuation
• The share sale could raise over $75 billion, making it the biggest IPO in history
• Space stocks surged Wednesday, with Firefly Aerospace up 16% and AST SpaceMobile up 10%

SpaceX could file for its initial public offering within days, according to a report from The Information. The filing would kick off what could become the largest stock market debut in history.

The company is targeting a valuation of around $1.75 trillion. If the share sale raises more than $75 billion as reported, it would surpass all previous IPO records.

News of the potential filing sent space stocks sharply higher on Wednesday. Firefly Aerospace led the gains, climbing 16% on the day.

AST SpaceMobile and Rocket Lab each rose around 10%. York Space, which held its own IPO in January, gained 5%.

AST SpaceMobile, Inc., ASTS

Intuitive Machines rose nearly 15%. Planet Labs jumped more than 10%, and Sidus Space gained close to 19%.

SpaceX was founded by Elon Musk in 2002. Musk also runs Tesla, X, Neuralink, and xAI.

SpaceX acquired Musk’s xAI last month. The combined company was valued at $1.25 trillion in that deal.

Musk currently has a net worth of more than $820 billion, according to Forbes. A SpaceX IPO at the reported valuation could push him past $1 trillion in personal wealth.

SpaceX has built a strong position in the aerospace industry over the past two decades. It holds billions of dollars in US government contracts.

SpaceX’s Satellite and Defense Business

The company operates Starlink, a satellite internet service with over 9,500 satellites currently in orbit. In January, Musk proposed expanding that to 1 million satellites, a plan that has drawn criticism from scientists over environmental concerns.

The space sector has also been boosted by President Donald Trump’s plans for a “Golden Dome” defense system. Companies focused on national defense and satellite technology have attracted increased investor interest as a result.

Data Centers in Space

There is growing discussion about putting data centers in space as a solution to rising electricity costs on the ground. The rapid buildout of AI infrastructure has driven up power demand, making space-based alternatives an area of interest.

However, this idea faces major barriers, including high launch costs and limited rocket availability.

SpaceX has not confirmed the IPO filing. The BBC reported it has contacted SpaceX for comment with no response at time of publication.

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